-# Copyright 2013-2017 by
-# David Turner, Robert Wilhelm, and Werner Lemberg.

-#
-# This file is part of the FreeType project, and may only be used, modified,

-# LICENSE.TXT. By continuing to use, modify, or distribute this file you

-#
-#
-# As a preliminary, create a compilation directory and change into it, for
-# example
-#
-# mkdir ~/freetype2.compiled
-# cd ~/freetype2.compiled
-#
-# Now you can say
-#
-# cmake <path-to-freetype2-src-dir>
-#
-# to create a Makefile that builds a static version of the library.
-#
-# For a dynamic library, use
-#
-# cmake <path-to-freetype2-src-dir> -D BUILD_SHARED_LIBS:BOOL=true
-#
-# For a framework on OS X, use
-#
-# cmake <path-to-freetype2-src-dir> -D BUILD_FRAMEWORK:BOOL=true -G Xcode
-#
-# instead.
-#
-# For an iOS static library, use
-#
-# cmake -D IOS_PLATFORM=OS -G Xcode <path-to-freetype2-src-dir>
-#
-# or
-#
-# cmake -D IOS_PLATFORM=SIMULATOR -G Xcode <path-to-freetype2-src-dir>
-#
-# Please refer to the cmake manual for further options, in particular, how
-# to modify compilation and linking parameters.
-#
-# Some notes.
-#
-# . `cmake' creates configuration files in
-#
-# <build-directory>/include/freetype/config
-#
-# which should be further modified if necessary.
-#
-# . You can use `cmake' directly on a freshly cloned FreeType git
-# repository.
-#
-# . `CMakeLists.txt' is provided as-is since it is normally not used by the
-# developer team.
-#
-# . If you want to disable the automatic generation of the distribution
-# targets, add the `-D FREETYPE_NO_DIST=true' command line argument.
-#
-# . Set the `WITH_ZLIB', `WITH_BZip2', `WITH_PNG', and `WITH_HarfBuzz'
-# CMake variables to `ON' or `OFF' to force or skip using a dependency.
-# Leave a variable undefined (which is the default) to use the dependency
-# only if it is available. Example:
-#
-# cmake ... -DWITH_ZLIB=ON -DWITH_HarfBuzz=OFF ...
-#
-# . Installation of FreeType can be controlled with the CMake variables
-# `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'
-# (this is compatible with the same CMake variables in zlib's CMake
-# support).

-
- Handle some integer overflow run-time errors (#46149, #48979).
-
- This commit (mainly for 32bit CPUs) is the first of a series of
- similar commits to handle known integer overflows. Basically, all
- of them are harmless, since they affect rendering of glyphs only,
- not posing security threats. It is expected that fuzzying will show
- up more overflows, to be fixed in due course.
-
- The idea is to mark places where overflows can occur, using macros
- that simply cast to unsigned integers, because overflow arithmetic
- is well defined in this case. Doing so suppresses run-time errors
- of sanitizers without adding computational overhead.

- warning because the macro itself uses `double' literals).

-
- [smooth] Implement minimal dynamic padding for LCD filtering.
-
- Extra bitmap padding for LCD filtering depends on the filter. The
- default 5-tap filter needs 2 extra subpixels. The light 3-tap filter
- needs only 1 extra subpixel. This space could be already available
- due to rounding. In order to optimize the padding, we now expand
- CBox for the given filter weights before rounding.

-
- [autofit] Fix metrics computation.
-
- Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and
- Nikolaus Waxweiler <madigens@gmail.com>.
-
- * src/base/ftobjs.c (FT_Request_Size): Trigger recomputation of
- auto-hinter metrics. Without this change, multiple size changing
- calls for a single face fail.
-
-2017-04-29 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttdriver.c (tt_size_request): Properly check `error'.
-
- Reported by Earnestly <zibeon@googlemail.com> in
-
- http://lists.nongnu.org/archive/html/freetype/2017-04/msg00031.html
-
-2017-04-27 Werner Lemberg <wl@gnu.org>
-
- Introduce AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option.
-
- * include/freetype/config/ftoption.h
- (AF_CONFIG_OPTION_TT_SIZE_METRICS): New option, commented out by
- default.
-
- * src/autofit/afloader.c (af_loader_load_glyph): Use
- AF_CONFIG_OPTION_TT_SIZE_METRICS to guard the corresponding code.
-
-2017-04-26 Werner Lemberg <wl@gnu.org>

-2017-04-22 Werner Lemberg <wl@gnu.org>
-
- [truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470).
-
- * src/truetype/ttobs.h (TT_SizeRec): Add field `hinted_metrics' to
- hold hinted metrics.
- Make `metrics' a pointer so that `tt_glyph_load' can easily switch
- between metrics.
-
- * src/truetype/ttdriver.c (tt_size_request): Updated.
- (tt_glyph_load): Use top-level metrics if FT_LOAD_NO_HINTING is
- used.
-
- * src/truetype/ttgload.c (TT_Hint_Glyph, TT_Process_Simple_Glyph,

-
-2017-04-22 Werner Lemberg <wl@gnu.org>
-
- Add new `slight' auto-hinting mode.
-
- This mode uses fractional advance widths and doesn't scale glyphs
- horizontally, only applying vertical scaling and hinting.
-
- At the same time, the behaviour of the `light' auto-hinter gets
- restored for backward compatibility: Both vertical and horizontal
- scaling is again based on rounded metrics values (this was changed
- in a commit from 2017-03-30 as a side effect). To be more precise,
- the behaviour is restored for TrueType fonts only; for other font
- formats like Type 1, this is a new feature of the `light' hinting
- mode.
-
- * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
- (FT_RENDER_MODE_SLIGHT): New render mode.
-
- * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add
- `autohint_mode' and `autohint_metrics' fields.
-
- * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c

-
- * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use
- `autohint_metrics'.
- (af_loader_load_glyph): s/internal/slot_internal/.
- Initialize `autohint_metrics' and `autohint_mode' depending on
- current auto-hint mode.
- Use `autohint_metrics'.
- Updated.
-
- * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated.
-
- * src/base/ftobjs.c (FT_Load_Glyph): Updated.

- structure with a single field `module_data'.
-
- * src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of
- `FT_Size' structure.
-
- * src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use

- [autofit] Prevent overlapping blue zones.
-
- Problem reported as
-
- https://github.com/google/fonts/issues/632
-
- The font in question (Nunito) has values 705 and 713 for the
- reference and overshoot values, respectively, of the first blue
- zone. Blue zone 2, however, has value 710 for both the reference
- and overshoot. At 12ppem, reference and overshoot of blue zone 0
- becomes 8px, while blue zone 2 becomes 9px.
-
- A peculiarity of this font is that the tops of isolated vertical
- stems like `N' have a slight overshoot also. The auto-hinter tries
- to find the nearest blue zone using the *original* coordinates. For
- vertical stems, this is value 713. For normal horizontal tops like
- in character `E', this is value 710. Since value 713 is mapped to
- 8px but value 710 to 9px, `N' and similar characters are one pixel
- higher than `E', which looks very bad.
-
- This commit sanitizes blue zones to avoid such a behaviour.

- [autofit] Use better blue zone characters for lowercase latin.

- FreeType must select between two different values, having a 50%

- [gzip] Improve building with external zlib (#49673).
-
- Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
- the following error.
-
- ftgzip.c
- zlib-1.2.8\zlib.h(86): error C2061:
- syntax error: identifier 'z_const'
- zlib-1.2.8\zlib.h(94): error C2054:
- expected '(' to follow 'z_const'
- zlib-1.2.8\zlib.h(94): error C2085:
- 'msg': not in formal parameter list
- ...
- zlib-1.2.8\zlib.h(877): fatal error C1003:
- error count exceeds 100; stopping compilation
-
- The error happens because FreeType keeps an own copy of zlib-1.1.4
- under `src/gzip'. When building `src/gzip/ftgzip.c' with
- FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
-
- #include <zlib.h>
-
- which correctly finds an external `zlib.h', but `zlib.h' itself has
- a line
-
- #include "zconf.h"
-
- which makes Visual Studio 2015 find `src/gzip/zconf.h' while
- compiling the files in `src/gzip'.
-
- * src/gzip/zconf.h: Rename to...
- * src/gzip/ftzconf.h: ... this.
- * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

-
- It's unavoidable to call the PNG engine, but to get the metrics it
- is sufficient to read the PNG image's header only.
-
- * src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the
- allocation of the glyph slot.
- * src/sfnt/pngshim.h: Updated.

- * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and
- offset also in `ebdt_size' and `ebdt_start', respectively. This
- makes the test for an embedded bitmap data table succeed for this

-2016-11-06 Seigo Nonaka <nona@google.com>
- Werner Lemberg <wl@gnu.org>
-
- Introduce a way of quickly retrieving (embedded) bitmap metrics.
-
- `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
- until the user calls `FT_Render_Glyph'. However, it always
- allocates memory for bitmaps and copies or decodes the contents of a
- bitmap glyph, which can be quite slow for PNG data.
-
- * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New

-
- * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if

- [pcf] Enrich family name with foundry name and glyph width info.

- This is a very old patch from openSuSE (from 2006, submitted to
- FreeType in 2011) that I forgot to apply.
-
- https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
-
- Prepend the foundry name plus a space to the family name. There are
- many fonts just called `Fixed' which look completely different, and
- which have nothing to do with each other. When selecting `Fixed' in
- KDE or Gnome one gets results that appear rather random, the style
- changes often if one changes the size and one cannot select some
- fonts at all.
-
- We also check whether we have `wide' characters; all put together,
- we get family names like `Sony Fixed' or `Misc Fixed Wide'.

- FreeType handle the whole `glyf' table as a single glyph again and
- again, which is certainly invalid (and can be very slow, too).

-
-2016-09-01 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [smooth] Simplify span rendering more.
-
- It turns out that there is significant cost associated with `FT_Span'
- creation and calls to `gray_render_span' because it happens so
- frequently. This removes these steps from our internal use but leaves
- it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
- is about 5%.
-
- * src/smooth/ftgrays.c (gray_render_span): Removed. The code is
- migrated to...
- (gray_hline): ... here.
-
-2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [smooth] Streamline pixmap drawing a bit more.
-
- Zero coverage is unlikely (1 out of 256) to warrant checking. This
- gives 0.5% speed improvement in rendering simple glyphs.
-
- * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
-
-2016-08-29 Alexei Podtelezhnikov <apodtele@gmail.com>
-

- (gray_TWorker): ... here.
- (gray_render_span): Move pixmap flow check from here...
- (gray_raster_render): .. to here.
-
-2016-08-27 Alexei Podtelezhnikov <apodtele@gmail.com>

-2016-08-06 Jon Spencer <jon@jonspencer.ca>
-
- [sfnt] Fix `FT_Get_Advance' for bitmap strikes.
-
- `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
- advance value from the font table and then scales it by the
- `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
- set that value for bitmap fonts and the advance gets scaled to zero.

-
- Since 2016-05-16 we detect infinite recursion directly.
-
- * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
- `maxComponentDepth'.
- * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if

-
- [truetype] Record the end of IDEFs.
-
- To match the logic in FDEF. The value of the end is only used for

- stretching information.
-
-2016-07-16 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] Make all glyphs in `Zycon' GX font work.
-
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
- tests.
-
-2016-07-16 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix GX delta tracing.
-
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
- relative point movements.
-
-2016-07-16 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] More fixes for GX.
-
- This finally fixes the rendering of the cyclist and the lizard in
- the `Zycon' font.
-
- * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
- index is always cumulative.
-
- (tt_handle_deltas): Rename to...
- (tt_interpolate_deltas): ... This.
- Add new parameter for output point array.
- Update caller.
-
- (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
- the intermediate results of `tt_interpolate_deltas' that are to be
- added to `outline->points'.
-
-2016-07-15 Werner Lemberg <wl@gnu.org>
-
- * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
-
- `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.
-
- Reported by Alexei.

-2016-07-16 Nikolaus Waxweiler <madigens@gmail.com>
-
- * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.

-
- * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
- `delta' also.
- Don't show first point of segment as a replacement for `pos'; this
- is (a) misleading, since the difference to `pos' can be almost
- arbitrarily large in corner cases, and (b) it is better to have all
- segment data in font units instead of a single value given in output
- space coordinates.
- Improve layout.
- (af_glyph_hints_dump_edges): Show px->units and units->px conversion
- values for convenience.
- Improve layout.
-
-2016-07-15 Werner Lemberg <wl@gnu.org>

-
-2016-07-14 Behdad Esfahbod <behdad@behdad.org>
-
- [truetype] Fix gxvar delta interpolation.
-
- The coordinates of the base font should be used for interpolation
- purposes, NOT the current points (i.e., the result of accumulation
- of previous deltas).
-
- * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
- `points_org' before looping over all tuples.

-2002-01-03 David Turner <david@freetype.org>
-
- * src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the

-
- There still is a bug there, though.
-
- * src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
-
-2001-12-30 David Turner <david@freetype.org>

-
- * builds/dos/detect.mk: Correcting the order for Borland compilers:

-
- * src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'
- and fix incorrect computation of `available_sizes'.
-
-2001-12-22 David Turner <david@freetype.org>
-
- * src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
- incorrect glyph advance in the case of mono-width fonts (like
- Courier, Andale Mono, and others).
-
-2001-12-22 Detlef Würkner <TetiSoft@apg.lahn.de>
-
- * builds/amiga/*: Adaptations to latest changes.

-
- * src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):
- Ignore invalid `hintmask' and `cntrmask' operators (instead of
- returning an error). Glyph 2028 of the CFF font `MSung-Light-Acro'
- couldn't be rendered otherwise (it seems its charstring is buggy,
- though this requires more analysis).
- (FT_COMPONENT): Define.
-
- * src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c
- (T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a
- bug where the X and Y axis where inverted in the postscript hinter.
- This caused problem when displaying on non-square surfaces.
-
- * src/pshinter/pshalgo2.c: s/vertical/dimension/.
-
- * src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
- point constant with a fixed-float equivalent. For some reasons not
- all compilers are capable of directly computing a floating pointer
- constant casted to FT_Fixed, and will link a math library instead.

- Yet another massive rewrite of the caching sub-system in order to
- both increase performance and allow simpler cache sub-classing. As
- an example, the code for the image and sbit caches is now much
- simpler.
-
- I still need to update the documentation in
- www/freetype2/docs/cache.html to reflect the new design though.
-
- * include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
- macro.
- (FT_CACHE_INTERNAL_CACHE_H): Updated.
-
-2001-12-05 David Krause <freetype@davidkrause.com>

-
- * include/freetype/ttnameid.h: Added some new Microsoft language
- codes and LCIDs as found in MSDN (Passport SDK). Also added
- comments about the meaning of bit 57 of the `OS/2' table
- (TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is
- a character beyond 0xFFFF in this font'. Thanks to Detlef Würkner
- <TetiSoft@apg.lahn.de> for noticing this.
-
-2001-11-20 David Turner <david@freetype.org>

- routine that created nasty alignment artefacts.
-
- * src/pshinter/pshrec.c, tests/gview.c: Debugging updates.
-
- * src/smooth/ftgrays.c: De-activated experimental gamma support.
- Apparently, `optimal' gamma tables depend on the monitor type,
- resolution and general karma, so it's better to compute them outside
- of the rasterizer itself.
- (gray_convert_glyph): Use `volatile' keyword.
-
-2001-10-29 David Turner <david@freetype.org>
-
- Adding experimental `gamma' support. This produces smoother glyphs
- at small sizes for very little cost.
-
- * src/smooth/ftgrays.c (grays_init_gamma): New function.
- (gray_raster_new): Use it.
-
- Various fixes to the auto-hinter. They merely improve the output of
- sans-serif fonts. Note that there are still problems with serifed
- fonts and composites (accented characters).
-

- ah_outline_link_segments): Implement it.
- Fix typos.
- (ah_outline_save, ah_outline_compute_segments): Fix typos.

- (AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
- (making them global as `ah_debug_disable_horz' and
- `ah_debug_disable_vert').
- Fix typos.
-
- * tests/gview.c: Updated the debugging glyph viewer to show the
- hints generated by the `autohint' module.
-
-2001-10-27 David Turner <david@freetype.org>
-
- * src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
- considerably lowered the performance of the abstract chunk cache.
-
-2001-10-26 David Turner <david@freetype.org>
-
- * include/freetype/ftcache.h, include/freetype/cache/*.h,
- src/cache/*.c: Major re-design of the cache sub-system to provide
- better performance as well as an `Acquire'/`Release' API. Seems to
- work well here, but probably needs a bit more testing.
-
-2001-10-26 Leonard Rosenthol <leonardr@lazerware.com>
-
- * builds/mac/README: Updated to reflect my taking over the project
- and that is now being actively maintained.

-2001-10-23 David Turner <david@freetype.org>
-
- * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
- Improvements to the memory debugger to report more information in
- case of errors. Also, some allocations that occurred through REALLOC
- couldn't be previously caught correctly.
-
- * src/autohint/ahglyph.c (ah_outline_compute_segments,
- ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
- src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
- liberal uses of memset() by the MEM_Set() macro.
-

- builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
- src/base/ftdbgmem.c: Updated the memory debugger and
- platform-specific implementations of `ftsystem' in order to be able
- to debug memory allocations on Unix, VMS and Amiga too!
-
- * src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
- some bogus warnings.
-
- * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
- Modified the debugging memory manager to report the location (source
- file name + line number) where leaked memory blocks are allocated in
- the source file.
-
- * src/base/ftdbgmem.c: New debugging memory manager. You must
- define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it. It
- will record every memory block allocated and report simple errors
- like memory leaks and double deletes.
-
- * src/base/Jamfile: Include ftdbgmem.
- * src/base/rules.mk: Ditto.
- * src/base/ftbase.c: Include ftdbgmem.c.

- FT_DEBUG_MEMORY is defined.
-
-2001-10-21 Tom Kacvinsky <tkacvins@freetype.org>
-
- * src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
- we are working with a CID keyed CFF font. Otherwise, a variable
- that was never allocated memory might freed. This is a correction
- to the previous patch for freeing subfonts.
-
-2001-10-21 Tom Kacvinsky <tkacvins@freetype.org>
-
- * src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to

-
- * src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
- src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes

-
-2001-10-20 Tom Kacvinsky <tkacvins@freetype.org>
-
- * src/type1/t1load.c (parse_encoding): Add a test to make sure
- that custom encodings (i.e., neither StandardEncoding nor
- ExpertEncoding) are not loaded twice when the Type 1 font is
- synthetic.
-
- * src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
- for when loading synthetic fonts to make sure that the font name
- and subroutines are not loaded twice. This is to remove a memory
- leak that occurred because the original memory blocks for these
- objects were not deallocated when the objects were parsed the
- second time.
-
-2001-10-19 David Turner <david@freetype.org>
-
- * src/smooth/ftgrays.c, src/pshinter/pshglob.h,

-
- * src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
- `glnames.py' script used to generate the `pstables.h' header file.
- The old one contained a serious bug that made FreeType return
- incorrect glyph names for certain glyphs.
-
- * src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
- pixel size from character size to use rounding. This is an
- experiment to see whether this gives values similar to Windows for
- scaled ascent/descent/etc.
-
- * src/base/ftcalc.c (FT_Div64by32): Changed the implementation
- slightly since the original code was mis-compiled on Mac machines
- using the MPW C compiler.
-
- * src/base/ftobjs.c (FT_Realloc): When a memory block was grown
- through FT_Realloc(), the new bytes were not set to 0, which created
- some strange bugs in the PostScript hinter.
- (destroy_face): Don't deallocate unconditionally.
-
- * src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
- Adding support to new PostScript hinter.
-
- * include/freetype/internal/psglobal.h,
- include/freetype/internal/pshints.h,

- src/type1/t1objs.h: Updates to use the new PostScript hinter.
-
- * tests/Jamfile, tests/gview.c: Adding a new glyph hinting
- viewer/debugger to the source tree. Note that you will _not_ be
- able to compile it since it depends on an unavailable graphics
- library named `Nirvana' to render vector images.
-
-2001-10-17 David Turner <david@freetype.org>
-
-

-
- * src/smooth/ftgrays.c: Include <setjmp.h>.

- CFF driver is finished with them. Added tables
-
- cff_isoadobe_charset
- cff_expert_charset
- cff_expertsubset_charset
- cff_standard_encoding
- cff_expert_encoding
-
- so that the encoding/charset parser can handle predefined encodings and

-2000-12-24 Tom Kacvinsky <tkacvins@freetype.org>
-

- transform is applied.
-
- * src/cff/cffparse.c (cff_parse_font_matrix): Added code so that

-
-2000-12-21 Tom Kacvinsky <tkacvins@freetype.org>
-
- * src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):

- names directly. Make them configurable. Use `##' to strip leading
- and trailing spaces from arguments.

- is now installed as <ft2build.h> for Unix systems. Note that we
- still use the `freetype2/freetype' installation path for now.
-
- * */*.[ch]: Now using <ft2build.h> as the default build and setup
- configuration file in all public headers. Internal source files
- still need some changes though.

-
-2000-11-30 David Turner <david.turner@freetype.org>

- * include/config/ftbuild.h, include/internal/internal.h: Added new
- configuration files used to determine the location of all public,
- configuration, and internal header files for FreeType 2. Modified

- Say you have `(Foo*)x' and want to assign, pass, or return it as
- `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
- would warn you that type casting incompatible pointer types breaks
- strict-aliasing. The solution is to cast to `(void*)' instead which
- is the generic pointer type, so the compiler knows that it should
- make no strict-aliasing assumption on `x'. But the problem with
- `(void*)x' is that seems like in C++, unlike C, `void*' is not a
- generic pointer type and assigning `void*' to `Bar*' without a cast
- causes an error. The solution is to cast to `Bar*' too, with
- `(Bar*)(void*)x' as the result -- this is what the patch does.

-
-2005-02-25 David Turner <david@freetype.org>
-
- Implement several memory optimizations to drastically reduce the
- heap usage of FreeType, especially in the case of memory-mapped
- files. The idea is to avoid loading and decoding tables in the
- heap, and instead access the raw data whenever possible (i.e., when
- it doesn't compromise performance).
-
- This has several benefits: For example, opening vera.ttf now uses
- just a small amount of memory (even when the FT_Library footprint is
- accounted for), until you start loading glyphs. Even then, you save
- at least 20KB compared to the non-optimized case. Performance of
- various operations, including open and close, has also been
- dramatically improved.
-
- More optimizations to come, especially for the auto-hinter.
-
- * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New
- function type.

- `vert_metrics', `vert_metrics_size', `hdmx_table',
- `hdmx_table_size', `hdmx_record_count', `hdmx_record_size',
- `hdmx_record_sizes', `kern_table', `kern_table_size,
- `num_kern_tables', `kern_avail_bits', `kern_order_bits' if
- FT_OPTIMIZE_MEMORY is set.
- Don't define `hdmx', `num_kern_pairs', `kern_table_index',
- `kern_pairs' if FT_OPTIMIZE_MEMORY is set.

- * src/base/ftdbgmem.c (ft_mem_table_set): Don't shadow variable.

-
- The very problem is that both the PCF and BDF drivers do a lot more
- than necessary to detect that they cannot handle a font file.

- now seems to be 100% equivalent to the auto-hinter, while being
- about 2% faster (which proves that script-specific algorithm
- selection isn't a performance problem).
-
- To test it, change `autohint' to `autofit' in
- <freetype/config/ftmodule.h> and recompile.
-
- A few more testing is needed before making this the official
- auto-hinting module.

-
- Make the PS parser more tolerant w.r.t. non-standard font data. In
- general, an error is only reported in case of a syntax error; a
- wrong type is now simply ignored (if possible). To be independent
- of the order of various MM-specific keywords, the parse_shared_dict
- routine has been removed -- the PS parser is now capable to skip
- this data. It no longer fails on parsing e.g.
-
- dup /WeightVector exch def
-
- Since the token following /WeightVector isn't `[' (starting an
- array) it is simply ignored.
-
- * include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a
- new internal error value.

- (parse_shared_dict): Removed.
- (parse_encoding): Set parser->root.error to return T1_Err_Ignore
- if no result can be obtained.
- Check for errors before accessing `elements' array.
- (t1_keywords): Remove /shareddict.
- (parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.
- Set keyword_flag only in case of success.
- Check error code if skipping an unrecognized token.
- (T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend
- if blend commands haven't set up a proper MM font.
-
- * src/psaux/psobjs.c (ps_parser_load_field_table): Remove special
- code for synthetic fonts.
- Return PSaux_Err_Ignore if no proper value has been found.

-
-2004-02-01 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1load.c (parse_charstrings): Exit immediately if

- like Optima-Oblique which not only define /CharStrings but access it
- also.

- this for non-standard fonts like `Optima' which have different
- outlines depending on the resolution. Note that there is no
- guarantee that we get fitting /Subrs and /CharStrings arrays; this
- can only be done by a real PS interpreter.

-
- *Complete* rewrite of the cache sub-system to `solve' the
- following points:
-
- - all public APIs have been moved to FT_CACHE_H, everything
- under `include/freetype/cache' is only needed by client
- applications that want to implement their own caches
-
- - a new function named FTC_Manager_RemoveFaceID to deal
- with the uninstallation of FaceIDs
-
- - the image and sbit cache are now abstract classes, that
- can be extended much more easily by client applications
-
- - better performance in certain areas. Further optimizations
- to come shortly anyway...
-
- - the FTC_CMapCache_Lookup function has changed its signature,
- charmaps can now only be retrieved by index
-
- - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
- FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
- private header for the moment)

-
- A new try to synchronize bitmap font access.
-
- * include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
- defined to return the baseline-to-baseline distance. This was

-
- Redesigning the FNT driver to return multiple faces, not multiple
- strikes. At least one font (app850.fon from WinME) contains
- different FNT charmaps for its subfonts. Consequently, the previous
- design of having multiple bitmap strikes in a single font face fails
- since we have only one charmap per face.
-

-
- Synchronize computation of height and width for bitmap strikes. The

-2003-06-08 Werner Lemberg <wl@gnu.org>
-
- Completely revised FreeType's make management.
-
- . In all makefiles `/' is used as the path separator. The
- conversion to the real path separators is done as late as
- possible using $(subst ...).
-
- . $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
- for the operating system, and the new $(COMPILER_SEP) the path
- separator for the compiler tools.
-
- . $(BUILD) has been renamed to $(BUILD_DIR). In general, all
- directory variables end with `_DIR'. The variants ending in `_'
- (like `BASE_' have been removed).
-
- The following ChangeLog entries only describe changes which are
- not related to the redesign.

-
-2003-04-25: Graham Asher <graham.asher@btinternet.com>
-
- Added the optional unpatented hinting system for TrueType. It
- allows typefaces which need hinting to produce correct glyph forms
- (e.g., Chinese typefaces from Dynalab) to work acceptably without
- infringing Apple patents. This system is compiled only if
- TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
- ftoption.h.
-
- * include/freetype/ttunpat.h: New file. Defines
- FT_PARAM_TAG_UNPATENTED_HINTING.

-
-
- * Version 2.1.4 released.
- =========================
-
-
-2003-04-03 Martin Muskens <mmuskens@aurelon.com>
-
- * src/type1/t1load.c (T1_Open_Face): Fixed the code to make it
- handle special cases where a font only contains a `.notdef' glyph

-
-2003-03-27 David Turner <david@freetype.org>
-
- * README: Updated.
-
- * README.UNX: Removed (now replaced by docs/INSTALL.UNX).

- used.
- (psh3_dimension_quantize_len): Enabled.
- (psh3_hint_align): Enable commented code.
- (psh3_hint_align_light): Commented out.
-
- * src/base/ftobjs.c (FT_Set_Char_Size): Changed the default

- provide accurate kerning data when native TrueType hinting is
- enabled.
-
- * src/type1/t1load.c (is_name_char): The Type 1 loader now accepts
- more general names according to the PostScript specification (the
- previous one was too restrictive).

-
-2003-03-20 David Turner <david@freetype.org>
-

-
- Introduced three new functions to deal with glyph bitmaps within
- FT_GlyphSlot objects:
-

-
-2003-03-15 David Turner <david@freetype.org>
-
- * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a small rounding
- bug. Actually, it seems that previous versions of FreeType didn't
- perform TrueType rounding exactly as appropriate.
-
-2003-03-14 David Turner <david@freetype.org>
-
- * src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small
- TrueType native rendering glitches; they came from a small rounding
- error.
-
-2003-03-13 David Turner <david@freetype.org>
-
- Added new environment variables to control memory debugging with
- FreeType. See the description of `FT2_DEBUG_MEMORY',
- `FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT.
-

-
-2003-02-25 David Turner <david@freetype.org>
-
- * src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that
- caused FreeType to loop endlessly when trying to read certain
- compressed gzip files. The following test reveals the bug:
-
- touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
-
- Several fixes to the PFR font driver:
-
- - The list of available embedded bitmaps was not correctly set in
- the root FT_FaceRec structure describing the face.
-
- - The glyph loader always tried to load the outlines when
- FT_LOAD_SBITS_ONLY was specified.
-
- - The table loaded now scans for *undocumented* elements of a
- physical font's auxiliary data record. This is necessary to
- retrieve the `real' family and style names.
-
- NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!
-
- * src/pfr/pfrload.c (pfr_aux_name_load): New function.
- (pfr_phy_font_done): Free `family_name' and `style_name' also.

- bytes.
-
- * src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.
- (pfr_face_init): Provide fallback values for `family_name' and
- `style_name'.

- * src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',
- `descent', `leading', `family_name', and `style_name'.
-
- * src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug
- when computing the scale factors for a given character size in
- points with resolution.
-
- * devel/ft2build.h, devel/ftoption.h: New files (in a new directory)
- which are special development versions of include/ft2build.h and
- include/freetype/config/ftoption.h, respectively.
-
-2003-02-18 David Turner <david@freetype.org>

- `exec->metrics'.
-
- * src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width
- `correction' which seemed to provide more trouble than benefits.
-
-2003-02-13 Graham Asher <graham.asher@btinternet.com>
-
- Changed the incremental loading interface in a way that makes it
- simpler and allows glyph metrics to be changed (e.g., by adding a
- constant, as required by CFF fonts) rather than just overridden.
- This was required to make the GhostScript-to-FreeType bridge work.
-
- * src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:
- Allow metrics to be overridden.
- * src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:
- Ditto.
-
- * src/truetype/ttgload.c (load_truetype_glyph)
- [FT_CONFIG_OPTION_INCREMENTAL]: Simplify.
- (compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block
- moved down.

- src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,
- src/gzip/infutil.c: Removed old-style (K&R)function definitions.
- This avoids warnings with Visual C++ at its most pedantic mode.
-
- * src/pfr/pfrsbit.c: Removed compiler warnings.
-
- * src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR
- into an FT_TRACE1 since it caused `ftview' and others to dump too
- much junk when trying to display a waterfall with a font without a
- Unicode charmap (e.g. SYMBOL.TTF).
-
- Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last
- patch from David Chester, but with a much simpler (and saner)
- implementation.
-
- * src/autohint/ahhint.c (ah_hinter_load_glyph)
- [FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that
- the top of non-capital letters is aligned on a pixel boundary
- whenever possible.
-
- * src/base/ftobjs.c (FT_Set_Char_Size)
- [FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.

-
- * src/truetype/ttobjs.c (Reset_Outline_Size)
- [FT_CONFIG_CHESTER_ASCENDER]: Round differently.
-
- * src/pshinter/pshalgo3.c: Improved the Postscript hinter. Getting
- rid of stem snapping seems to work well here (though the stems are
- still slightly moved to increase contrast).
- (psh3_dimension_quantize_len): Commented out.
- (psh3_hint_align_light): New function.
- (psh3_hint_align): Comment out some code.
-
- THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES
- STILL SUCK.
-
-2003-01-22 David Chester <davidchester@qmx.net>
-
- * src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the
- stem width optimization.

-
- * src/sfnt/ttload.c (tt_face_load_metrics)
- [FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without
- horizontal metrics (without the `hmtx' table) are now tolerated if

- GhostScript.
-
-2003-01-11 David Chester <davidchester@qmx.net>
-
- Patches to the auto-hinter in order to slightly improve the output.

- also individual FT_CONFIG_CHESTER_XXX macros to control individual
- `features'.
-
- Note that all improvements are enabled by default, but can be

- version of `ah_compute_stem_width'.
- (ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem
- alignment when stem widths are less than 1.5 pixels wide centers the
- stem slightly off-center of the center of a pixel (this increases
- sharpness and consistency).
- [FT_CONFIG_CHESTER_SERIF]: Use special version of
- `ah_compute_stem_width'.
- * src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add
- `AH_BLUE_SMALL_F_TOP'.
-
-2003-01-11 David Turner <david@freetype.org>

- last release.
- (open_face): Fix return value.
-
-2003-01-08 Owen Taylor <owen@redhat.com>
-
- Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and

- (ft_stroker_outside): Handle `phi' together with `theta'.
- (FT_Stroker_ParseOutline): New function.
-
- * src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned

- incorrect stroker computations, among other things).
-
- * src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect
- assertion, and changing code to avoid hash table size contraction.
-
- * src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding

- =========================
-
-
-2002-11-07 David Turner <david@freetype.org>
-
- * src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that
- caused problems with embedded bitmaps.
-
- * src/otlayout/otlayout.h, src/otlayout/otlconf.h,
- src/otlayout/otlgsub.c, src/otlayout/otlgsub.h,
- src/otlayout/otlparse.c, src/otlayout/otlparse.h,
- src/otlayout/otlutils.h: Updating the OpenType Layout code, adding
- support for the first GSUB lookups. Nothing that really compiles
- for now though.
-
- * src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem
- width quantization. It produces slightly better shapes though this
- is not distinguishable with many fonts.
- Remove other dead code.
-
- * src/Jamfile, src/*/Jamfile: Simplified.

-
-2002-11-06 David Turner <david@freetype.org>

- configuration (typically by adding -D flags at compile time).
-
- * src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler
- warnings in optimized mode relative to the `volatile' local
- variables. This was not a compiler bug after all, but the fact that
- a pointer to a volatile variable is not the same as a volatile
- pointer to a variable :-)
-
- The fix was to change
- `volatile FT_Byte* p'
- into
- `FT_Byte* volatile p'.
-
- * src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c

-
-2002-08-29 David Turner <david@freetype.org>
-
- Slight modification to the Postscript hinter to slightly increase
- the contrast of smooth hinting. This is very similar to what the

-2002-08-27 David Turner <david@freetype.org>
-
- * Massive re-formatting changes to many, many source files. I don't
- want to list them all here. The operations performed were all
- logical transformations of the sources:
-
- - trying to convert all enums and constants to CAPITALIZED_STYLE,
- #with define definitions like
-
- #define my_old_constants MY_NEW_CONSTANT
-
- - big, big update of the documentation comments
-
- * include/freetype/freetype.h, src/base/ftobjs.c,
- src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support
- for LCD-optimized rendering though the new constants/enums:
-
- FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
- FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
-
- This is still work in progress, don't expect everything to work
- correctly though most of the features have been implemented.
-
- * Adding new FT_LOAD_XXX flags, used to specify both hinting and
- rendering targets:
-
- FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering

- hinting & rendering
- FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated
- hinting & rendering
-
- Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
- behaviour of the font engine is _unchanged_.

-2002-08-23 Graham Asher <graham.asher@btinternet.com>
-
- * src/cff/cffgload.c (cff_operator_seac)
- [FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not
- incremental in the case of CFF but just using callbacks to get glyph
- recipes) pass the character code, not the glyph index, to the
- get_glyph_data function; they have no valid charset table.
-
- * src/cff/cffload.c (cff_font_load): Removed special cases for

-
-2002-08-21 David Turner <david@freetype.org>

-2002-08-01 Graham Asher <graham.asher@btinternet.com>
-
- * src/type1/t1load.c (T1_Open_Face): Tolerate a face with no
- charstrings if there is an incremental loading interface. Type 1
- faces supplied by PostScript interpreters like GhostScript will

- essential if they are to work.
-
-2002-08-01 Graham Asher <graham.asher@btinternet.com>
-
- Modified incremental loading interface to be closer to David's
- preferences. The header freetype.h is not now affected, the

-2002-07-18 Graham Asher <graham.asher@btinternet.com>
-

- X11-compatible string describing the font format of a given face.
- This was put in a new optional base source file, corresponding to a
- new public header (named FT_XFREE86_H since this function should

-
- Fixing the SFNT name table loader to support various buggy fonts.
- It now ignores empty name entries, entries with invalid pointer
- Offsets and certain fonts containing tables with broken
- `storageOffset' fields.
-
- Name strings are now loaded on demand, which reduces the memory
- requirements for a given FT_Face tremendously (for example, the name
- table of Arial.ttf is about 10Kb and contains 70 names).
-
- This is a temporary fix. The whole name table loader and interface
- will be rewritten in a much more cleanly way shortly, once CSEH have
- been introduced in the sources.
-
- * include/freetype/internal/tttypes.h (TT_NameEntryRec): Change
- type of `stringOffset' to FT_ULong.

- Make code more robust.
- * src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.
- Handle invalid `storageOffset' data better.
- Set length fields to zero for invalid or ignored data.
- Remove code within FT_DEBUG_LEVEL_TRACE.
- (TT_Free_Names): Updated.
-
-2002-05-24 Tim Mooney <enchanter@users.sourceforge.net>
-
- * builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and
- FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be
- rebuilt from sources. Set macro serial to 1, and use third argument
- to AC_DEFINE for our two custom symbols, so ftconfig.in could one day
- be rebuilt with autoheader (not recommended now, ftconfig.in is a
- custom source file)
-

- (FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings
- from a face. This is much cleaner than accessing the internal types
- `BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H.
-

- that returned global BBox values in 16.16 fixed format (instead of
- integer font units).

- slash (`/') as in `/MOEKai-Regular'.
-
- * src/sfnt/ttload.c (TT_Load_Names), src/sfnt/sfobjs.c (Get_Name),
- src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
- that it accepts broken fonts like `foxjump.ttf', which made FreeType
- crash when trying to load them.
-
- Also improved the name table parser to be able to load
- Windows-encoded entries before Macintosh or Unicode ones, since it
- seems some fonts don't have reliable values here anyway.
-
- * include/freetype/internal/psnames.h: Add typedef for
- `PSNames_Service'.
-
-2002-03-05 Werner Lemberg <wl@gnu.org>

-
- becomes
-
- typedef PS_StructRec_
- {
- } PS_StructRec, *PS_Struct;
-
- typedef PS_StructRec T1_Struct; /* backward compatibility */
-
- Hence, we increase the coherency of the source code by effectively
- using the `Rec' prefix for structure types.
-
-2002-02-27 David Turner <david@freetype.org>
-
- * src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the

- experimental SFNT charmap processing support.
-
- * include/freetype/internal/ftobjs.h: Adding validation support as
- well as internal charmap object definitions (FT_CMap != FT_CharMap).
-
-2002-02-24 David Turner <david@freetype.org>

- initializes it for reading.)
-
- FT_New_Memory_Stream( library, FT_Byte* base, size, stream ) =>
- FT_Stream_Open_Memory( stream, const FT_Byte* base, size )
-
- FT_Done_Stream => FT_Stream_Close
- FT_Stream_IO => FT_Stream_IOFunc
- FT_Stream_Close => FT_Stream_CloseFunc
-
- ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only)

- respectively).
-
- * include/freetype/internal/ftobjs.h: Moving all code related to
- glyph loaders to ...

-2006-05-02 David Turner <david@freetype.org>
-
- Update the memory management functions and macros to safely deal
- with array size buffer overflows. This corresponds to attempts to
- allocate arrays that are too large. For an example, consider the
- following code:
-
- count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
- count ); for ( nn = 0; nn < count; nn++ )
- array[nn] = read_item_from_file();
-
- If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
- multiplication overflows, and the array allocated os smaller than
- the data read from the file. In this case, the heap will be
- trashed, and this can be used as a denial-of-service attack, or make
- the engine crash later.
-
- The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
- count is no larger than `FT_INT_MAX/item_size', otherwise a new
- error code `FT_Err_Array_Too_Large' will be returned.
-
- Note that the memory debugger now works again when FT_DEBUG_MEMORY
- is defined. FT_STRICT_ALIASING has disappeared; the corresponding
- code is now the default.
-
-
- * include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
- Don't use `extern'.
-
- * include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
- code.
-
- * include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)

- FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
- place where the frames were entered, extracted, exited or released
- in the memory debugger.
-
- * src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
- Call ft_mem_free.
- (FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
- (FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.

-
-
- Fix binary compatibility issues for gnustep-back (GNUstep backend
- module) which still crashes under Sarge.
-
- * src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,
- FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
- structures and enumerations.
- (FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
- compatibility code.
-
- * src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to
- support rogue clients compiled against 2.1.7 to work correctly.
- This probably explains the GNUstep crashes with the second release
- candidate.
-

-
- * include/freetype/ftoutln.h (enum FT_Orientation): New value
- `FT_ORIENTATION_NONE'.
-
- * src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
- ft_contour_enclosed, ft_outline_get_orientation): Another version of
- `FT_Outline_Get_Orientation'. This version differs from the public
- one in that each part (contour not enclosed in another contour) of the
- outline is checked for orientation.
- (FT_Outline_Embolden): Use `ft_outline_get_orientation'.
-
- * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
- use bitmap's embolden routine when the outline one failed.
-
-2006-02-22 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
- compatibility.
-
- * src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.
-
- * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
- tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
- loading. (Only tested with bit aligned sbit with x_pos == 0.)
-
- * src/truetype/ttpload.c (tt_face_load_hdmx,
- tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not
- actually used.
-
-2006-02-21 David Turner <david@freetype.org>
-
- Add a new API named FT_Get_TrueType_Engine_Type to determine whether
- we have a patented, unpatented, or unimplemented TrueType bytecode
- interpreter.
-
- The FT_Get_Module_Flags API was removed consequently.
-
- * include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.
- Replaced with...
- (FT_Get_TrueType_Engine_Type): This.
- (FT_TrueTypeEngineType): New enumeration.
-
- * include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H):
- New macro.
-
- * src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
- (FT_Module_Get_Flags): Removed. Replaced with...

- embedded bitmaps from being correctly listed and used.
-
-
- * src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
- if FT_CONFIG_OPTION_OLD_INTERNALS is used. The is necessary because
- libXfont is directly accessing the HMTX data, unfortunately.
- Fix some compiler warnings.
- (tt_face_get_metrics): Ditto.
-
-
- * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
- character advances.
-
-2006-02-20 David Turner <david@freetype.org>
-
- Support binary compatibility with the X.Org server's Xfont library.
- Note that this change unfortunately prevents memory optimizations
- for the embedded bitmap loader.
-
- * include/freetype/internal/sfnt.h (SFNT_Interface): Move
- `set_sbit_strike' and `load_sbit_metrics' fields to the location of
- version 2.1.8.
-
- * src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call
- FT_Size_Request.

- FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup)
- [FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the
- cache sub-system. We try to recognize old legacy signatures with a
- gross hack (hope it works).
-
-2006-02-17 Werner Lemberg <wl@gnu.org>
-
- * devel/ftoption.h: Synchronize with
- include/freetype/config/ftoption.h.
-
-2006-02-16 David Turner <david@freetype.org>
-
- Massive changes to the internals to respect the internal object
- layouts and exported functions of FreeType 2.1.7. Note that the
- cache sub-system cannot be fully retrofitted, unfortunately.
-
- * include/freetype/config/ftoption.h
- (FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

- src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:
- Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data
- structures.
-
- Move newly added structure elements to the end of the affected
- structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is
- defined) to assure binary compatibility with older FreeType
- versions.
- Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old
- functions:
-
- ft_stub_set_char_sizes
- ft_stub_set_pixel_sizes
-
- Rename the following internal functions to provide the old function
- names as stubs:
-
- FT_Alloc -> ft_mem_alloc

- FT_Realloc -> ft_mem_realloc
- FT_QRealloc -> ft_mem_qrealloc

-
-2006-02-15 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
- unused `max_points' and `max_contours'.
-
- * src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
- (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.
-
- * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
- `max_components'.
-
- * src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
- `loadSize' and `loadStack'.
-
- * src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
- src/sfnt/ttload.c (tt_face_load_maxp): Update.
-
- * src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
- (sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
- compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
- defined.
-
- * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
- possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
- (finally!)
-
-
- For most OpenType tables, `tt_face_load_xxxx' simply loads the table
- and `face->root' is set later in `sfnt_load_face'. Here, we try to
- make this work for _all_ tables. Also improve tracing messages.
-
- * src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
- src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
- then exit. Error handling or setting face->root is done later in
- `sfnt_load_face'.
-
- * src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
- Mac bitmap-only fonts are not scalable.
- Check that `face->header.Units_Per_EM' is not zero.
- (LOAD_, LOADM_): Emit pretty trace messages.
-
- * src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics
- from `eblc'.
-
- * src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
- (load_format_20, load_format_25, tt_face_get_ps_name): Use
- face->max_profile.numGlyphs, instead of face->root.num_glyphs.
-
-2006-02-14 Werner Lemberg <wl@gnu.org>

- documentation of `outline' field.
-
- * src/sfnt/sfobjs.c: Include FT_INTERNAL_DEBUG_H.
- * src/sfnt/sfdriver.c: Include ttmtx.h.
-
- * src/autofit/afcjk.c: Include aftypes.h and aflatin.h.
-
-2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.
-
-2006-02-14 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
- return error if table is missing.
- Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
-
- * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
- tables. The last change makes Mac bitmap-only font not load and
- this fixes it.
-
- * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation
- error when FT_CONFIG_OPTION_INCREMENTAL is defined.
-
-2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
-
- Clean up the SFNT_Interface. In this final pass, `load_hmtx' is
- split from `load_hhea'.
-
- * include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
- src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.
-
- * src/sfnt/sfobjs.c (sfnt_load_face): Update.
-
-2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
- code...
-
-2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
-
- Clean up the SFNT_Interface. In this pass, we want to treat the
- font directory (offset table and table directory) as a normal table
- like the others. This also means that TTCs are no longer recognized
- there but in `init_face'.
-
- * include/freetype/internal/sfnt.h (SFNT_Interface),
- src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
- combined and renamed to `load_font_dir'.
-
- * src/sfnt/ttload.h, src/sfnt/ttload.c:
- s/sfnt_dir_check/check_table_dir/.
- `sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
- `tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
- and renamed to `tt_face_load_font_dir'.
-
- * src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
-
-2006-02-13 Chia-I Wu <b90201047@ntu.edu.tw>
-
- Clean up the SFNT_Interface. Table loading functions are now named
- after the tables' tags; `hdmx' is TrueType-specific and thus the
- code is moved to the truetype module; `get_metrics' is moved here
- from the truetype module so that the code can be shared with the cff
- module.
-
- This pass involves no real changes. That is, the code is moved
- verbatim mostly. The only exception is the return value of
- `tt_face_get_metrics'.
-
- * include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
- src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
- src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
- src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.
-
- * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files. Metrics-related
- tables' loading and parsing code is moved to here.
- Move `tt_face_get_metrics' here from the truetype module. The
- return value is changed from `void' to `FT_Error'.
-
- * include/freetype/internal/fttrace.h: New trace: ttmtx.
-
- * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
- parsing code is moved here.
- New function `tt_face_load_prep' split from `tt_face_load_fpgm'.
- `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.
-
- * src/cff/cffgload.c, src/cff/cffobjs.c: Update.
-
- * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.
-

- * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use
- AF_LatinMetricsRec as the dummy metrics because we cast the metrics
- to it later in `af_latin_hints_link_segments'.
-
-2006-02-11 Chia-I Wu <b90201047@ntu.edu.tw>
-
- * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define

-
- * src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure

- (af_latin_hints_link_segments): Potential divide-by-zero bug.
- Use latin constant in the scoring formula.
-
- * src/autofit/afcjk.c: Minor updates due to the above three changes.
-
- * docs/TODO, docs/CHANGES: Updated.
-
-2006-02-09 Chia-I Wu <b90201047@ntu.edu.tw>
-
- Introduce experimental autofit CJK module based on akito's autohint
- patch. You need to #define AF_MOD_CJK in afcjk.c to enable it.
-
- * src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
- src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
- Add CJK module based on akito's autohint patch.
-
- * src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
- overlap length of the segments.
- (AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros.
-
- * src/autofit/aflatin.h (af_latin_metrics_init_widths),
- src/autofit/aflatin.c (af_latin_metrics_init_widths): Made
- `FT_LOCAL'.
- Use the character given by the caller.
- (af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
- the thresholds.
-
- * src/autofit/afloader.c (af_loader_load_g): Respect
- AF_SCALER_FLAG_NO_ADVANCE.

-
-2006-01-31 Werner Lemberg <wl@gnu.org>
-
- Implement new, simplified module selection. With GNU make it is now
- sufficient to modify a single file, `modules.cfg', to control the
- inclusion of modules and base extension files.
-
- This change also fixes the creation of ftmodule.h; it now depends on
- `modules.cfg' and thus is rebuilt only if necessary.
-
- Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
- default location.
-
- * modules.cfg: New file.
-
- * builds/freetype.mk: Don't include `modules.mk'.
- Include all `rules.mk' files as specified in `modules.cfg'.
- (FTOPTION_FLAG, FTOPTION_H): New variables.
- (FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
- Add FTOPTION_FLAG.

- (remove_ftmodule_h): New phony target to delete `ftmodule.h'.
- (distclean): Add remove_ftmodule_h.
-
- * builds/modules.mk: (MODULE_LIST): Removed.
- (make_module_list, clean_module_list): Replace targets
- with...
- (FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
- variables. Reason for the change is that it is not possible to have
- a phony prerequisite which is run only if the target file must be
- rebuilt (phony prerequisites act like subroutines and are *always*
- executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
- changed.
- Update all callers.
- ($FTMODULE_H)): Rule to create `ftmodule.h', depending on
- `modules.cfg'.
-
- * builds/toplevel.mk: Rewrite and simplify module handling.
- (MODULES_CFG, FTMODULE_H): New variables.
- Include MODULES_CFG.

- files. We no longer use make's `wildcard' function for this.
-
- * Makefile (USE_MODULES): Remove. Update all users.
- (OBJ_DIR): Define it here.
-
- * src/*/module.mk: Change
-
- make_module_list: foo
- foo: ...
-
- to
-
- FTMODULE_H_COMMANDS += FOO
- define FOO
- ...
- endef
-
- in all files. `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.
-
- * src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.
-
- * builds/unix/detect.mk (setup): Always execute `configure' script.
- (have_mk): Rename to...
- (have_Makefile): This.
- Don't use `strip' function.
-
- * builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
- defined.
- (have_mk): Don't use `strip' function.
- Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
- accordingly).
-
- * builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
-
- * builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
- builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
- BUILD_DIR but DEVEL_DIR for development header files.

- same location as other generated objects (i.e., within the `objs'
- directory of the current directory).
-
-
- Add support for an embedded `BDF ' table within SFNT-based bitmap
- font files. This is used to store atoms & properties from the
- original BDF fonts that were used to generate the font file.
-
- The feature is controlled by TT_CONFIG_OPTION_BDF within
- `ftoption.h' and is used to implement FT_Get_BDF_Property for these
- font files.
-
- At the moment, this is still experimental, the BDF table format
- isn't cast into stone yet.

- to do `charcode => glyph index' by linear/binary search.

- * src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
- font to have no `head' table if tables `SING' and `META' are
- present; this is to support `SING Glyphlet'.
-
- `SING Glyphlet' is an extension to OpenType developed by Adobe
- primarily to facilitate adding supplemental glyphs to an OpenType
- font (with emphasis on, but not necessarily limited to, gaiji to a
- CJK font). A SING Glyphlet Font is an OpenType font that contains
- the outline(s), either in a `glyf' or `CFF' table, for a glyph;
- `cmap', `BASE', and `GSUB' tables are present with the same format
- and functionality as a regular OpenType font; there are no `name',
- `head', `OS/2', and `post' tables; there are two new tables, `SING'
- which contains details about the glyphlet, and `META' which contains
- metadata.
-
- Further information on the SING Glyphlet format can be found at:
-
- http://www.adobe.com/products/indesign/sing_gaiji.html
-
- * include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for
- the OpenType tables `SING' and `META'. These two tables are used in
- SING Glyphlet Format fonts.

-
- Really fix Savannah bug #28678 (part 2).
-
- Since we consider `sbw' for the horizontal direction only, we still have
- to synthesize vertical metrics if the user wants to use the vertical
- writing direction.
-

-
-2010-02-10 Ken Sharp <ken.sharp@artifex.com>
-
- Really fix Savannah bug #28678 (part 1).
-
- After long discussion, we now consider the character width vector
- (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
- direction only. For example, if you are using the horizontal
- writing direction, you get the horizontal and vertical components of
- the advance width for this direction. Note that OpenType and CFF fonts
- don't have such a vertical component; instead, the GPOS table can be
- used to generate two-dimensional advance widths (but this isn't
- handled by FreeType).

-
-2010-01-08 Ken Sharp <ken.sharp@artifex.com>
-
- Fix Savannah bug #28521.
-
- Issue #28226 involved a work-around for a font which used the
- `setcurrentpoint' operator in an invalid way; this operator is only
- supposed to be used with the result of OtherSubrs, and the font used
- it directly. The supplied patch removed the block of code which
- checked this usage entirely.
-
- This turns out to be a Bad Thing. If `setcurrentpoint' is being
- used correctly it should reset the flex flag in the decoder. If we
- don't do this then the flag never gets reset and we omit any further
- contours from the glyph (at least until we close the path or
- similar).
-
- * src/psaux/t1decode.c (t1_decoder_parse_charstrings)

-
- Enable the incremental font interface by default.
-
- Ghostscript requires the incremental font interface for handling
- some Postscript documents. It is moving to using FreeType as its
- primary renderer; supporting this in the default build makes it
- Ghostscript to be linked against the system FreeType when one is
- available.

-2009-12-14 Ken Sharp <ken.sharp@artifex.com>
-
- Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
- This fixes Savannah bug #28226.
-
- At least two wild PostScript files of unknown provenance contain
- Type 1 fonts, apparently converted from TrueType fonts in earlier
- PDF versions of the files, which use the `setcurrentpoint' operator
- inappropriately.
-
- FreeType currently throws an error in this case, but Ghostscript and
- Adobe Distiller both accept the fonts and ignore the problem. This
- commit #ifdefs out the check so PostScript interpreters using
- FreeType can render these files.
-
- The specification says `setcurrentpoint' should only be used to set
- the point after a `Subr' call, but these fonts use it to set the
- initial point to (0,0). Unnecessarily so, as they correctly use an
- `hsbw' operation which implicitly sets the initial point.
-
- * src/psaux/t1decode.c (t1_decoder_parse_charstrings)

- void * typed data. But BDF driver always gives an unsigned long
- integer (the index to a property). To reduce non-essential
- casts from unsigned long to void* and from void* to unsigned
- long, the hash API is changed to take size_t integer.
- The issue of incompatible cast between unsigned long and void*
- on LLP64 platform is reported by NightStrike from MinGW-Win64
- project. See
- http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

- void* to size_t.
-
- * src/bdf/bdflib.c (hash_insert): Get size_t data, instead of
- void* data.

- (_bdf_set_default_spacing): Get the name length of the face by
- size_t variable, with a cut-off at 256.
- (bdf_get_property): Get the property id by size_t variable to

-
- Improve vertical metrics calculation (Savannah bug #27364).
-
- The calculation of `vertBearingX' is not defined in the OTF font
- spec so FreeType does a `best effort' attempt. However, this value
- is defined in the PDF and PostScript specs, and that algorithm is
- better than the one FreeType currently uses:
-
- FreeType: Use the middle of the bounding box as the X coordinate
- of the vertical origin.
-
- Adobe PDF spec: Use the middle of the horizontal advance vector as
- the X coordinate of the vertical origin.
-
- FreeType's algorithm goes wrong if you have a really small glyph
- (like the full-width, circle-like dot at the end of the sentence, as
- used in CJK scripts) with large bearings. With the FreeType
- algorithm this dot gets centered on the baseline; with the PDF
- algorithm it gets the correct location (in the top right). Note
- that this is a serious issue, it's like printing the dot at the end
- of a Roman sentence at the center of the textline instead of on the
- baseline like it should. So i believe the PDF spec's algorithm
- should be used in FreeType as well.
-
- The `vertBearingY' value for such small glyphs is also very strange
- if no `vmtx' information is present, since the height of the bbox is
- not representable for the height of the glyph visually (the
- whitespace up to the baseline is part of the glyph). The fix also
- includes some code for a better estimate of `vertBearingY'.
-
- * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
- is now calculated as described by the Adobe PDF Spec. Estimate for
- `vertBearingY' now works better for small glyphs completely above or
- below the baseline into account.
-
- * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
- calculated as described by the Adobe PDF Spec. Vertical metrics
- information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
- was not defined.
-
- * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
- now calculated as described by the Adobe PDF Spec.

-
- Use 16.16 format while parsing Type 1 charstrings.
- This fixes Savannah bug #26867.
-
- Previously, only integers have been used which can lead to serious
- rounding errors.
-
- However, fractional values are only used internally; after the
- charstrings (of either Type 1 or 2) have been processed, the
- resulting coordinates get rounded to integers currently -- before
- applying scaling. This should be fixed; at the same time a new load
- flag should be introduced, to be used in combination with
- FT_LOAD_NO_SCALE, which indicates that font units are returned in
- 16.16 format. Similarly, the incremental interface should be
- extended to allow fractional values for metrics.

-
- Fix B/W rasterization of subglyphs with different drop-out modes.
-
- Normally, the SCANMODE instruction (if present) to set the drop-out
- mode in a TrueType font is located in the `prep' table only and thus
- valid for all glyphs. However, there are fonts like `pala.ttf'
- which additionally contain this instruction in the hinting code of
- some glyphs (but not all). As a result it can happen that a
- composite glyph needs multiple drop-out modes for its subglyphs
- since the rendering state gets reset for each subglyph.
-
- FreeType collects the hinted outlines from all subglyphs, then it
- sends the data to the rasterizer. It also sends the drop-out mode
- -- after hinting has been applied -- and here is the error: It sends
- the drop-out mode of the last subglyph only; drop-out modes of all
- other subglyphs are lost.
-
- This patch fixes the problem; it adds a second, alternative
- mechanism to pass the drop-out mode: For each contour, the
- rasterizer now checks the first `tags' array element. If bit 2 is
- set, bits 5-7 contain the contour's drop-out mode, overriding the
- global drop-out mode.
-
- * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
-
- * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
- `tags[0]'.
-
- * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
- Use bits 3-5 instead of 0-2.
- (New_Profile): Set the drop-out mode in the profile's `flags' field.
- (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
- necessary.
- (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
- Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
- mode.
-
-2009-06-16 Werner Lemberg <wl@gnu.org>
-
- Improve scan conversion rules 4 and 6.
-
- Two new constraints are introduced to better identify a `stub' -- a
- concept which is only vaguely described in the OpenType
- specification. The old code was too rigorous and suppressed more
- pixel than it should.
-
- . The intersection of the two profiles with the scanline is less
- than a half pixel. Code related to this was already present in
- the sources but has been commented out.
-
- . The endpoint of the original contour forming a profile has a
- distance (`overshoot') less than half a pixel to the scanline.
-
- Note that the two additional conditions fix almost all differences
- to the Windows rasterizer, but some problematic cases remain.
-
- * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
- macros for the `flags' field in the `TProfile' structure.
- (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
- (New_Profile, End_Profile): Pass overshoot flag as an argument and
- set it accordingly.
- Update callers.
- (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
- constraints.
-
-2009-06-11 Werner Lemberg <wl@gnu.org>
-
- Increase precision for B/W rasterizer.
-
- * src/raster/ftraster.c (Set_High_Precision): Add two more bits to

- on my GNU/Linux box I don't see a performance degradation.

-
- * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
-
-2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
-
- Fix handling of EBDT formats 8 and 9 (part 2).
-
- This patch fixes the following problems in ttsbit0.c:
-
- . Bitmaps for compound glyphs were never allocated.
-
- . `SBitDecoder' refused to load metrics if some other metrics have
- already been loaded. This condition certainly makes no sense for
- recursive calls, so I've just disabled it. Another possibility
- would be resetting `decoder->metrics_loaded' to false before
- loading each composite component. However, we must restore the
- original metrics after finishing the recursion; otherwise we can
- get a misaligned glyph.
-
- . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
- causing some glyph components to be shifted too far to the right
- (especially noticeable for small sizes).
-
- Note that support for grayscale bitmaps (not necessarily compound) is
- completely broken in ttsbit0.c.
-
- * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
- (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
- of `h == height'.
- (tt_sbit_decoder_load_compound): Reset metrics after loading
- components.
- Allocate bitmap.

-
- FT_USE_MODULE declares things as:
-
- extern const FT_Module_Class
-
- (or similar for C++). However, the actual types of the variables
- being declared are often different, e.g., FT_Driver_ClassRec or
- FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
-
- This works with most C compilers (since those structs begin with an
- FT_Module_Class struct), but technically it's undefined behavior.
-
- To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
- paragraph 2:
-
- All declarations that refer to the same object or function shall
- have compatible type; otherwise, the behavior is undefined.
-
- (And they are not compatible types.)
-
- Most C compilers don't reject (or even detect!) code which has this
- issue, but the GCC LTO development branch compiler does. (It
- outputs the types of the objects while generating .o files, along
- with a bunch of other information, then compares them when doing the
- final link-time code generation pass.)
-
- Patch from Savannah bug #25133.

-
- Generalize the concept of `tricky' fonts by introducing
- FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
- engine is necessary for correct rendering.
-
- At the same time, slightly modify the behaviour of tricky fonts:
- FT_LOAD_NO_HINTING is now ignored. To really force raw loading
- of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
- FT_LOAD_NO_AUTOHINT must be used.
-
- Finally, tricky TrueType fonts always use the bytecode interpreter
- even if the patented code is used.

- New macros.

- Type1 and sfnt-wrapped CID-keyed font support.
-
-2008-09-18 Werner Lemberg <wl@gnu.org>
-
- * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
- orthogonality (ft_free and ft_sfree could belong to different memory
- pools). This fixes Savannah bug #24297.
-
-2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined

-
- * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
- and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
- prevent unconditional definition. This fixes Savannah bug #24241.
-
- * src/psnames/pstables.h: Regenerated.
-
-2008-09-13 Werner Lemberg <wl@gnu.org>
-
- * autogen.sh, builds/unix/configure.raw,
- include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
- beautifying.
-
- * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,

-
- * builds/unix/ftconfig.in: Duplicate the cpp computation of
- FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
- (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
- computation is disabled and the statically configured sizes are
- used. This fixes Savannah bug #21250.
-
- * builds/unix/configure.raw: Add the checks to compare the cpp
- computation results of the bit length of int and long versus the
- sizes detected by running `configure'. If the results are
- different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the

- undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
-
-2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
- ApplicationServices framework is missing. Although this value is not
- used in building of FreeType2, it is written in `freetype2.pc' and
- `freetype-config'.
-
-2008-09-01 David Turner <david@freetype.org>
-
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
- index to mean `use default cached FT_Face's charmap'. This fixes
- Savannah bug #22625.
- * include/freetype/ftcache.h: Document it.
-
-
- Make FT_MulFix an inlined function. This is done to speed up
- FreeType a little (on x86 3% when loading+hinting, 10% when
- rendering, ARM savings are more important though). Disable this by
- undefining FT_CONFIG_OPTION_INLINE_MULFIX.
-
- Use of assembler code can now be controlled with
- FT_CONFIG_OPTION_NO_ASSEMBLER.

- (FT_MULFIX_INLINED): New macro.
-
- * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
- FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
-
- * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
-
- * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
- FT_MULFIX_INLINED.
-
-
- Add a new header named FT_ADVANCES_H declaring some new APIs to
- extract the advances of one or more glyphs without necessarily
- loading their outlines. Also provide `fast loaders' for the
- TrueType, Type1, and CFF font drivers (more to come later).
-
- * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.

-
-2008-08-28 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1load.c (parse_encoding): Protect against infinite
- loop. This fixes Savannah bug #24150 (where a patch has been posted

-
-2008-08-23 Werner Lemberg <wl@gnu.org>
-
- * src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c
- (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug
- #24119.
-
-2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
- even if passed library or arguments are invalid. This fixes a bug
- that an uninitialized stream is freed when an invalid library handle
- is passed. Originally proposed by Mike Fabian, 2008/08/18 on
- freetype-devel.
- (FT_Open_Face): Ditto (stream).
- (load_face_in_embedded_rfork): Ditto (stream2).
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

- (e.g., a build with Jam).
- * builds/mac/ftmac.c: Ditto.
- * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
- explicitly, even if `ResourceIndex' is unavailable.
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: In checking of Mac OS X features,
- all-in-one header file `Carbon.h' is replaced by the minimum
- header file `CoreServices.h', similar to current src/base/ftmac.c.
-
-2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
- sub-header when its code_count is 0. Many Japanese Dynalab fonts
- include such an empty sub-header (code_count == 0, first_code == 0
- delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
-
-2008-08-04 Werner Lemberg <wl@gnu.org>
-
- * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
- Savannah bug #23995.
-
- * src/cid/cidload.c (parse_expansion_factor): New callback function.
- (cid_field_records): Use it for `ExpansionFactor'.
- * src/cod/cidtoken.h: Handle `ForceBold' keyword.

-
-2008-08-04 Bram Tassyns <bramt@enfocus.be>
-
- * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which

- adjust table count.
- Add more trace messages.
- (tt_face_load_font_dir): Updated.
-
-2008-07-30 Werner Lemberg <wl@gnu.org>
-
- * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
- assume that the first argument on the stack is the bottom-most
- element. Two reasons:
-
- o According to people from Adobe it is missing in the Type 2
- specification that pushing of additional, superfluous arguments
- on the stack is prohibited.
-
- o Acroread in general handles fonts differently, namely by popping
- the number of arguments needed for a particular operand (as a PS
- interpreter would do). In case of buggy fonts this causes a
- different interpretation which of the elements on the stack are
- superfluous and which not.
-
- Since there are CFF subfonts (embedded in PDFs) which rely on
- Acroread's behaviour, FreeType now does the same.
-
-2008-07-27 Werner Lemberg <wl@gnu.org>
-
- Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
- fixes Savannah bug #23940.
-
- * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...

- cff_decoder_parse_charstrings): Improve debug output.
-
-2008-07-22 Martin McBride <mmcbride@emtex.com>
-
- * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
- tt_cmap4_char_map_binary): Handle fonts which treat the last segment
- specially. According to the specification, such fonts would be
- invalid but acroread accepts them.
-
-2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
-
- * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

-2008-07-09 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
- where num_locations < num_glyphs. Problem reported by Ding Li.
-
-2008-07-05 Werner Lemberg <wl@gnu.org>
-
- Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
- newer. This fixes Savannah bug #23648.
-
- * configure: zsh doesn't like ${1+"$@"}.
- Update needed GNU make version.
- * builds/toplevel.mk: Check for `$(eval ...)'.
- * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
- it.
-
-2008-07-04 Werner Lemberg <wl@gnu.org>
-
- * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one

-
-2008-06-27 Werner Lemberg <wl@gnu.org>
-
- * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
- Horizontal_Gray_Sweep_Drop): Test for intersections which
- degenerate to a single point can be ignored; this has been confirmed
- by Greg Hitchcock from Microsoft. (This was commented out code.)
-
-2008-06-26 Werner Lemberg <wl@gnu.org>
-
- Improve navigation in API reference.
-
- * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...

- Update header files accordingly.
-
-2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
- and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
- bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
- ResourceIndex type definition. The macro does not inform the type
- availability.
- * src/base/ftmac.c: More parentheses are inserted to clarify the
- conditionals to disable legacy APIs in `10.5 and later' cases. If
- HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
-
-2008-06-24 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
- mode.

- bug #23683 (from John Tytgat).
-
-2008-06-22 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
- with IS_HINTED.
-
- * docs/CHANGES: Updated.
-
-2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
- but LDFLAGS does not, import it to LDFLAGS. The option is used to
- specify non-default SDK on Mac OS X (e.g., universal binary SDK for
- Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
- recommends to add the option only to CFLAGS, LDFLAGS should include
- it because libfreetype.la is built with -no-undefined. This fixes a
- bug reported by Ryan Schmidt in MacPorts,
- http://trac.macports.org/ticket/15331.
-
-2008-06-21 Werner Lemberg <wl@gnu.org>
-

- * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
- mode to FT_OUTLINE_XXX flags.
-
- * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
-
-2008-06-19 Werner Lemberg <wl@gnu.org>
-
- * src/cff/cffobjs.c (cff_face_init): Compute final
- `dict->units_per_em' value before assigning it to
- `cffface->units_per_EM'. Otherwise, CFFs without subfonts are
- scaled incorrectly if the font matrix is non-standard. This fixes
- Savannah bug #23630.
-
- * docs/CHANGES: Updated.
-
-2008-06-19 Werner Lemberg <wl@gnu.org>

-
- * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
- of the graphics state for subglyphs to...
- (TT_Hint_Glyph): This function.
- Hinting instructions for a composite glyph apparently refer to the
- just hinted subglyphs, not the unhinted, unscaled outline. This
- seems to fix Savannah bugs #20973 and (at least partially) #23310.
-
-2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

- proposed by an anonymous reporter of Savannah bug #23204.
-
-2008-05-18 Werner Lemberg <wl@gnu.org>
-
- * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
- correction for pixel boundary. Without this patch, the effect can
- be cumulative under certain circumstances, making glyphs taller and
- taller after each call. This fixes Savannah bug #19976.
-
-2008-05-18 Werner Lemberg <wl@gnu.org>

-
-2008-05-15 Werner Lemberg <wl@gnu.org>
-

- and not correct.
-
- * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
-
- * src/cff/cffgload.c (cff_builder_init): Updated.

-
-2008-05-03 Werner Lemberg <wl@gnu.org>
-

-
-2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
- synthesis. For any face of a specified FOND, always the name for
- the first face was used. Except of a FOND that refers multiple
- Type1 font files, wrong synthesized font names are not used at all,
- so this is an invisible bug. A few limit checks are added too.
-
- * builds/mac/ftmac.c: Ditto.
-
-2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- * builds/unix/configure.raw: Split compiler option to link Carbon

-
- * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
- handle by its value instead of ResError(), fix provided by Deron
- Kazmaier. According to the Resource Manager Reference,
- GetResource(), Get1Resource(), GetNamedResource(),
- Get1NamedResource() and RGetResource() set noErr but return NULL
- handle when they can not find the requested resource. These

- Improvement of POSIX resource-fork accessor to load unsorted
- references in a resource. In HelveLTMM (resource-fork PostScript
- Type1 font bundled with Mac OS X since 10.3.x), the appearance order
- of PFB chunks is not sorted; sorting the chunks by reference IDs is
- required.
-
- * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
- type to store a pair of reference ID and offset to the chunk.
-
- * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

-
-2007-12-14 Werner Lemberg <wl@gnu.org>
-
- * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
- division too early; otherwise the most significant digit(s) of the
- final result are lost as the value is truncated to an integer. This
- fixes Savannah bug #21794 (where the patch has been posted too).
-
-2007-12-06 Fix <4d876b82@gmail.com>
-
- Pass options from one configure script to another as-is (not

-
- * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to

-
- Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
- not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
- cannot mmap() the specified file and cannot seek to head of the
- specified file, it returns NULL stream and FT_Open_New() returns the
- error immediately. On MacOS, most legacy MacOS fonts fall into such
- a scenario because their data forks are zero-sized and cannot be
- sought. To proceed to guessing of resource fork fonts, the
- functions for legacy MacOS font must properly handle the NULL stream
- returned by FT_New_Stream().
-
- * src/base/ftobjs.c (IsMacBinary): Return error
- FT_Err_Invalid_Stream_Operation immediately when NULL stream is
- passed.
- (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
- to fallback. Originally, legacy MacOS font is tested in the cases
- of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
- or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
- .dfont header is combined). Now the case of
- FT_Err_Cannot_Open_Stream is included.
-
- * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
- skip FT_Stream_Seek(), which seeks to the head of stream, and
- proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
- for a NULL stream causes a Bus error on Mac OS X.
- (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
- immediately if passed stream is NULL.
- (raccess_guess_apple_single): Ditto.
-
-2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Fix for Carbon incompatibilities since Mac OS X 10.5,
- proposed by Sean McBride.
-
- * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
-
- * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
- FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
- Carbon functions from a forked process is classified as unsafe
- by Apple. All Carbon-dependent functions should be deprecated.
-
- * src/base/ftmac.c: Use essential header files
- <CoreServices/CoreServices.h> and
- <ApplicationServices/ApplicationServices.h> instead of
- all-in-one header file <Carbon/Carbon.h>.
-
- Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
- genuine macro PATH_MAX.
-
- Add fallback macro for kATSOptionFlagsUnRestrictedScope which
- is not found in Mac OS X 10.0.
-
- Multi-character constants ('POST', 'sfnt' etc) are replaced by
- 64bit constants calculated by FT_MAKE_TAG() macro.
-
- For the index in the segment of resource fork, new portable
- type ResourceIndex is introduced for better compatibility.
- This type is since Mac OS X 10.5, so it is defined as short
- when built on older platforms.
-
- (FT_ATSFontGetFileReference): If build target is only the systems
- 10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
-
- (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
- and newer or 64bit platform, because legacy type FSSpec type is
- removed completely.
-
- (FT_New_Face_From_FSSpec): Ditto.
-
-2007-11-01 Werner Lemberg <wl@gnu.org>
-
- * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
- fixes Savannah bug #21485.
-
-2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
-
- * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
- can handle the font at all, then check `face_index'. Otherwise, the
- driver might return the wrong error code. This fixes Savannah bug
- #21468.
-
-2007-10-21 Werner Lemberg <wl@gnu.org>
-
- * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
- support for bit 8 of the `fsSelection' field in the `OS/2' table.
- MS is already using this; hopefully, this becomes part of OpenType
- 1.5.
- Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
- (WWS_SUBFAMILY).
-
-2007-10-20 Werner Lemberg <wl@gnu.org>
-
- * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.

-
-2007-10-18 David Turner <david@freetype.org>
-
- * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
- functions related to cmap type 14 support to the

-
- FT_Get_Char_Variant_Index -> FT_Face_GetCharVariantIndex

-
- * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
- s/2.3.0/2.3.1/.
-
- * builds/unix/configure.raw (version_info): Set to 9:12:3.
-
-
- * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
- (af_loader_load_g): Disable the warper (i.e., the light hinting
- improvements) to make a 2.3.1 bugfix release before introducing a
- new feature. This should give us more time to tune and improve the

-
-2007-01-25 David Turner <david@freetype.org>
-
- For light auto-hinting, improve glyph advance widths and resurrect

-
-2007-01-25 Werner Lemberg <wl@gnu.org>

- correctly in a sanity check. Since this function is only used to
- load local and global functions, any charstring that called the last
- local/global function would fail otherwise. This fixes Savannah bug
- #18867.
-
- * docs/CHANGES: Document it.
-
-2007-01-23 David Turner <david@freetype.org>

- large Asian CFF fonts.
-
- * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
- which happens when FT_Done_Library is called with still opened

- theoretically happen. This fixes Savannah bug #16669.
-
- * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
- of `face->num_glyphs' which missed the last glyph, due to
- the offset-by-1 computation, since the PFR format doesn't

- glyph. This fixes Savannah bug #16668.
-

-
- This is a major patch used to drastically improve the performance of
- loading glyphs. This both speeds up loading the glyph vectors
- themselves and the auto-fitter module.
-
- We now use inline assembler code with GCC to implement `FT_MulFix',
- which is probably the most important function related to the
- engine's performance.
-
- The resulting speed-up is about 25%.
-
-

- reducing the number of loops.
-
- * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
-
-
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
- used to detect rogue clients from 4 to 16. This is to prevent some
- segmentation faults with fonts like `KozMinProVI-Regular.otf' which
- comes from the Japanese Adobe Reader Asian Font pack.
-
-2007-05-17 Werner Lemberg <wl@gnu.org>
-
- * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This

-
- [cff] Make Adobe CFF engine work correctly on 64bit hosts.
-
- Reported by numerous people on the `freetype-devel' list. Without
- this fix, glyphs aren't properly aligned on a common baseline.
-
- On 64bit systems, `FT_Pos' expands to `long int', having a width of
- 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on
- 64bit hosts also. Wrong casts filled up the blues arrays with
- incorrect values. Note that all blues values are accessed with the
- `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
-
- * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
- cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
- `data', not `CF2_Fixed'.
- * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
- cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.
- * src/cff/cf2blues.c (cf2_blues_init): Updated.

-2013-04-13 Werner Lemberg <wl@gnu.org>
-
- [cff] Add a new Type 2 interpreter and hinter.
-
- This work, written by Dave Arnold <darnold@adobe.com> and fully
- integrated into FreeType by me, is a donation by Adobe in
- collaboration with Google. It is vastly superior to the old CFF
- engine, and it will replace it soon. Right now, it is still off by
- default, and you have to explicitly select it using the new
- `hinting-engine' property of the cff driver.
-
- For convenience, (most of) the new files are committed separately.
-
- * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
- * include/freetype/ftcffdrv.h: New file to access CFF driver
- properties.
- * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
- code.
- * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
- and `cf2interp'.
-
- * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
- * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
- and `no_stem_darkening'.
- * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
-
- * src/cff/cff.c: Include new files.
- * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
- `hinting-engine' and `no-stem-darkening' properties (only the Adobe
- engine listens to them).
- * src/cff/cffgload.c: Include `cf2ft.h'.
- (cff_decoder_prepare): Initialize `current_subfont'.
- (cff_build_add_point): Handle Adobe engine which uses 16.16
- coordinates.
- (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
- separately.
- Choose rendering engine based on `hinting_engine' property.
- * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
- engine.
- * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
- (cff_driver_init): Set default property values.
-
- * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.
-
- * src/cff/cf2*.*: New files, containing the Adobe engine.

-
-2013-03-31 Werner Lemberg <wl@gnu.org>
-
- * configure: Use egrep, not grep.
-

-
- [autofit] Minor.
-
- * src/autofit/afmodule.c (af_property_set): Typo.
- (af_autofitter_init, af_autofitter_done): Use cast.
-
-2013-03-21 Werner Lemberg <wl@gnu.org>
-
- * configure: Automatically test for `gmake' also.
-
- Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
-
-2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de>
-
- Respect CONFIG_SHELL from the environment.
-
- Some large packages using FreeType have to use a broken (deficient)
- /bin/sh. The configure scripts (as generated by Autoconf) are
- clever enough to find a better shell and put that one into the
- environment variable CONFIG_SHELL. If that environment variable is
- already set the script skips the test and assumes to be already
- running under a good shell.
-
- * builds/unix/detect.mk: Honour CONFIG_SHELL.
- * builds/unix/unix-def.in (SHELL): Define.
-
-2013-03-21 Werner Lemberg <wl@gnu.org>
-
- Fix Savannah patch #7971.
-
- * configure: Handle MAKE environment variable also.
-
-2013-03-17 Werner Lemberg <wl@gnu.org>
-
- Fix Savannah bug #38538.
-
- * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
- builds/wince/ftdebug.c (FT_Throw): Add function.
-
-2013-03-17 Werner Lemberg <wl@gnu.org>
-
- [raster] Remove dead code.
-
- * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
- src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
-
-2013-03-17 Werner Lemberg <wl@gnu.org>
-
- * src/pshinter/pshpic.h (GET_PIC): Use correct container.
-
-2013-03-15 Werner Lemberg <wl@gnu.org>
-
- * include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
-
- The previous version was not backward compatible. Reported by
- Behdad.
-
-2013-03-14 Werner Lemberg <wl@gnu.org>
-
- */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
-
- FT_Err_XXX and friends are no longer directly used in the source
- code.
-
-2013-03-14 Werner Lemberg <wl@gnu.org>
-
- New error management macros.
-
- * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
- * include/freetype/fttypes.h: ... this file.
- (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
- macros.
-
- * include/freetype/freetype.h: Updated.
-
-2013-03-14 Werner Lemberg <wl@gnu.org>
-
- */*: Use FT_Err_Ok only.
-
- This is a purely mechanical conversion.
-
-2013-03-14 Werner Lemberg <wl@gnu.org>
-
- */*: Use `FT_THROW'.
-
- This is essentially a mechanical conversion, adding inclusion of
- `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
- stand-alone compiling modes of the rasterizer modules.
-
- To convert the remaining occurrences of FT_Err_XXX and friends it is
- necessary to rewrite the code. Note, however, that it doesn't harm
- if some cases are not handled since FT_THROW is a no-op.
-
-2013-03-13 Werner Lemberg <wl@gnu.org>
-
- Introduce `FT_THROW' macro.
-
- The idea is to replace code like
-
- return FT_Err_Foo_Bar;
-
- or
-
- return CFF_Err_Foo_Bar;
-
- with
-
- return FT_THROW( Foo_Bar );
-
- The FT_THROW macro has two functions:
-
- . It hides the module specific prefix.
-
- . In debug mode, it calls the empty function `FT_Throw' which can
- be thus used to set a breakpoint.
-
- * include/freetype/internal/ftdebug.h (FT_THROW): New macro.
- (FT_Throw): New prototype.
- * src/base/ftdebug.c (FT_Throw): New function.
-
-2013-03-12 Werner Lemberg <wl@gnu.org>
-
- Remove `FT_KEEP_ERR_PREFIX'.
-
- The idea is to always have FT_ERR_PREFIX available internally.
-
- * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
- undefinition of FT_ERR_PREFIX
-
- * src/gxvalid/gxverror.h, src/otvalid/otverror.h,
- src/sfnt/sferrors.h: Updated.
-
-2013-03-11 Werner Lemberg <wl@gnu.org>
-
- [gxvalid] Fix module error.
-
- * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as
- FT_Mod_Err_GXvalid.
- * include/freetype/ftmoderr.h: Add module error for `GXvalid'.
-
-2013-03-11 Werner Lemberg <wl@gnu.org>
-
- Always use module related error codes.
-
- * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
- (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use
- `FT_ERROR_BASE'.
-
- * src/type1/t1load.c (parse_encoding): Use
- T1_Err_Unknown_File_Format.
-
-2013-03-08 Werner Lemberg <wl@gnu.org>
-
- [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.

-
-2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [base] Fix commit ab02d9e8.
-
- * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
-
-2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [base] New bisecting BBox_Cubic_Check (disabled).
-
- * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm
- for extremum search built around simple condition that defines
- which half contains the extremum.
-
-2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [tools] Update BBox testing tool.
-
- * src/tools/test_bbox.c: Add another cubic outline with exact BBox.
- (REPEAT): Increase the number of benchmarking cycles.
- (profile_outline): Tweak output formatting.
-
-2013-02-02 Werner Lemberg <wl@gnu.org>
-
- Fix Savannah bug #38235.
-
- * builds/unix/configure.raw: Don't generate `freetype-config' and
- `freetype.pc'.
-
- * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,
- build_libtool_libs, ft_version): New variables to be substituted.
- (freetype-config, freetype.pc): New rules to generate those files.
-
- * builds/unix/freetype-config.in: Remove code for handling `rpath'.
- The use of $rpath has been accidentally removed in a patch from
- 2009-12-22, and apparently noone has missed it since.
- Use `%' instead of `@' as a variable substitution marker.
- Use quotes.
-
- * builds/unix/freetype.in: Use `%' instead of `@' as a variable
- substitution marker.
- Use quotes.
-
-2013-02-07 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
-
- BTW, Greg agrees that the OpenType specification is missing the list
- of GS variables which will always be reset to the default values
- after the `prep' table has been executed.
-
-2013-02-06 Werner Lemberg <wl@gnu.org>
-
- * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
-
- Up to now, we simply took a snapshot of the Graphics State after the
- `prep' table has been executed, and right before a glyph's bytecode
- was run it got reloaded. However, as Greg Hitchcock has told us in
- private communication, reference points get reset to zero in the MS
- rasterizer and we follow in due course. While reasonable, this is
- undocumented behaviour.
-
- Most notably, this fixes the rendering of Arial's `x' glyph in
- subpixel hinting mode.
-
-2013-02-05 Werner Lemberg <wl@gnu.org>
-
- [truetype] A better fix for Savannah bug #38211.

-
- [sfnt] Fix broken pointer overflow checks.
-
- Many compilers such as gcc and clang optimize away pointer overflow
- checks `p + n < p', because pointer overflow is undefined behavior.
- Use a safe form `n > p_limit - p' instead.
-
- Also avoid possible integer overflow issues, for example, using
- `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'
- given a large `num_glyphs'.

-
- [truetype] Improve sub-pixel code.
-
- This patches fixes many issues with the ttsubpix implementation.
-
- 1. Data tables are defined, instead of declared, in the header, and
- thus copied into each source file that includes it.
-
- 2. These tables were defined as global, mutable, visible variables,
- and thus costing private RAM to every process that loads the
- library (> 50 KB / process, this is huge!).
-
- Additionally, this also made the library export the symbols
- completely needlessly.
-
- 3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
-
- Note that this doesn't try to fix the incredibly inefficient storage
- format for the data tables used by the code. This one will require
- another pass in the future.
-
- * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS):
- Renamed to...

- [truetype] Improve accuracy of normalization of short vectors.
-
- Unit vector components are stored as 2.14 fixed-point numbers. In
- order to calculate all 14 bits accurately, a short vector to be
- normalized has to be upscaled to at least 14 bits before its length
- is calculated. This has been safe since accurate CORDIC algorithms
- were adopted.
-
- * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.
-
-2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [truetype] Kill very old vector normalization hacks.
-
- Back in the days, vector length calculations were not very accurate
- and the vector normalization function, Normalize, had to meticulously
- correct the errors for long vectors [commit b7ef2b096867]. It was no
- longer necessary after accurate CORDIC algorithms were adopted, but
- the code remained. It is time to kill it.
-

-
- [base] Improve trigonometric core.
-
- FreeType used to rely on a 24-step iteration CORDIC algorithm to
- calculate trigonometric functions and rotate vectors. It turns out
- that once the vector is in the right half-plane, the initial rotation
- by 63 degrees is not necessary. The algorithm is perfectly capable
- to converge to any angle starting from the second 45 degree rotation.
- This patch removes the first rotation and makes it a 23-step CORDIC
- algorithm.
-
- * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro
- values.
- (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial

-
- [truetype] Scale F_dot_P down.
-
- The dot product between freeVector and projVector or cosine of
- the angle between these FT_F2Dot14 unit vectors used to be scaled up
- by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
- This patch scales the value down by 2^14 instead, which simplifies
- its use throughout the bytecode interpreter.
-
- This does not lead to the loss of precision because the lower bits
- are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
- for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
- These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
- rounding and F_dot_P is assigned 0x26660000. The lower bits were
- already lost while rounding the unit vector components.
-
- Besides code simplification, this change can lead to better
- performance when FT_MulDiv with the scaled-down F_dot_P is less
- likely to use the costly 64-bit path. We are not changing the type
- of F_dot_P to FT_F2Dot14 at this point.
-
- * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
- bits and modify its use accordingly.
- (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
- the use of F_dot_P field.
- * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
- assignment of F_dot_P to its theoretical maximum in case we decide
- to scale back its type later.

- so-called `Infinality patch', taken from
-
- http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
-
- which addresses various enhancements of the auto-hinter. Without
- properties to control a module's metadata it wasn't possible to
- adapt the patches because everything was originally controlled by
- environment variables which I consider not suitable in general.

- Fix `checking if gcc static flag -static works' test.
-
- On my linux build tree, I receive yes answer in every package I
- build except freetype for this test checking if gcc static flag
- `-static' works
-
- On freetype, no is received, unless bzip2 and zlib are disabled using
-
- ./configure --without-bzip2 --without-zlib
-
- The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
- LDFLAGS and this broke static flag test.

-
- [truetype] Support subpixel hinting.
-
- This is the large, famous `Infinality' patch to support ClearType
- bytecode which has been available from
- http://www.infinality.net/blog/ for some time, and which has been
- refined over the last years. While still experimental, it is now
- mature enough to be included directly into FreeType.
-
- Most of the code is based on the ClearType whitepaper written by
- Greg Hitchcock
-
- http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
-
- which gives a detailed overview of the necessary changes to the
- Microsoft rasterizer so that older fonts are supported. However, a
- lot of details are still missing, and this patches provides a
- framework to easily handle rendering issues down to the glyph level
- of certain fonts.
-

-
- [autofit] Return correct linear advance width values.
-
- This was quite a subtle bug which accidentally showed up with glyph
- `afii10023' of arial.ttf (version 2.76). This glyph is a composite;
- the first component, `E', has an advance width of 1366 font units,
- while the advance width of the composite itself (which looks like
- uppercase `E' with dieresis) is 1367 font units. I think this is
- actually a bug in the font itself, because there is no reason that
- this glyph has not the same width as uppercase `E' without the
- dieresis. Anyway, it helped identify this problem.
-
- Using the TrueType hinter, the correct value (1367) of `afii10023'
- was returned, but the autohinter mysteriously returned 1366.
-
- Digging in the code showed that the autohinter recursively calls
- FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
- flag. However, the `linearHoriAdvance' field is still returned as a
- scaled value. To avoid scaling twice, the old code in autofit reset
- `linearHoriAdvance', using the `horiAdvance' field. This seemed to
- work since FT_LOAD_NO_SCALE was in use, but it failed actually,
- because `horiAdvance' is defined as the distance of the first
- subglyph's phantom points, which in turn are initialized using the
- advance width of the first subglyph. And as the given example
- shows, these widths can differ.
-
- * src/autofit/afloader.c (af_loader_load_g): Temporarily set
- FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
- values for the linear advance widths.

- [truetype] Fix SSW instruction.

- * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units. For

-
- [autofit] Fix the inclusion of `aflatin2.h' in PIC file.
-
- * src/autofit/afpic.c: Include `aflatin2.h' when
- FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
- Unconditionally inclusion causes declared but unimplemented
- warning by GCC 4.6.
-
-2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
-
- * src/cff/cffpic.c: The declarations of
- FT_Init_Class_cff_cmap_encoding_class_rec() and
- FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
- They can be obtained by the inclusion of cffcmap.h.
- cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
- FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
-
-2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Fix redundant declaration warning in PIC mode.
-
- Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
- designed to declare xxx_pic_{free,init} by themselves.
- Because these macros are used at the end of the module
- interface (e.g. ttdriver.c) and the wrapper source to build
- a module as a single object (e.g. truetype.c) includes
- the PIC file (e.g. ttpic.c) before the module interface,
- these macros are expanded AFTER xxx_pic_{free,init} body
- when the modules are built as single object.
- The declaration after the implementation causes the redundant
- declaration warnings, so the declarations are moved to module
- PIC headers (e.g. ttpic.h). Separating to other header files
- are needed for multi build.
-
- * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
- Remove class_##_pic_free and class_##_pic_init declarations.
- * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
- FT_DEFINE_MODULE): Ditto.
-
- * src/base/basepic.h: Insert a comment and fix coding style.
- * src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
- init}.
- * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
- * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
- init}.
- * src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
- init}.
- * src/raster/rastpic.h: Declare
- ft_raster{1,5}_renderer_class_pic_{free,init}
- * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
- * src/smooth/ftspic.h: Declare
- ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
- * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
-
-2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Make pspic.c to include module error header to fix multi build.
-
- * src/psnames/pspic.c: Include `psnamerr.h'.
-
-2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [base] Fix a dereference of uninitialized variable in PIC mode.
-
- * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
- set before dereferring to obtain `library'. The initialization
- of `clazz', `glyph', `library' and NULL pointer check are
- reordered to minimize PIC conditionals.
-
-2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [base] Insert explicit cast for GCC 4.6 in PIC mode.
-
- * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
- configuration, FT_DEFAULT_MODULES_GET returns
- FT_Module_Class** pointer, GCC 4.6 warns that
- const FT_Module_Class* const* variable is warned as
- inappropriate to store it. To calm it, explicit cast is
- inserted. Also `library' is checked to prevent the NULL
- pointer dereference in FT_DEFAULT_MODULES_GET.
-
-2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
-
- Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
- take no arguments but derefer the variable named `library'
- internally.
-
- * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
- set it if non-NULL driver is passed.
- * src/truetype/ttdriver.c (tt_get_interface): Ditto.
-
- * src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'
- under PIC configuration, and set it if non-NULL module is given.
- * src/psnames/psmodule.c (psnames_get_interface): Ditto.
-
-2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

-
-2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
-
- Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
- was a configurable macro to disable Carbon-dependent code. Because
- now configure script sets DARWIN_NO_CARBON by default and disables
- Darwin & Carbon-dependent codes, these macros can be unified.
- FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
- (defined by default) is removed, because DARWIN_NO_CARBON violates
- FT_XXX naming convention of public macros, and a macro configured by
- default is not portable for the building without configure (e.g.
- make devel).
-
- * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
- old Mac font support is requested and Carbon is available.
- * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
- for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
- requested.
- * include/freetype/config/ftconfig.in: Ditto.
- * builds/vms/ftconfig.h: Ditto.
-
- * src/base/ftbase.h: Remove DARWIN_NO_CARBON.
- * src/base/ftbase.c: Ditto.
- * src/base/ftobjs.c: Ditto.
- * src/base/ftrfork.c: Ditto.
-
- * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
- (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
- * builds/mac/ftmac.c: Ditto.
-
- * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
- * builds/mac/FreeType.m68k_far.make.txt: Ditto.

-
- Fix Savannah bug #34728 (`make devel' on Mac OS X).
-
- * builds/toplevel.mk: Check `/dev/null' to identify the Unix-

-
- [apinames] Fix the overflow of signed integer hash.
-
- * src/tools/apinames.c (names_add): Change the type of `h' from
- int to unsigned int, to prevent undefined behaviour in the
- overflow of signed integers (overflow of unsigned int is defined
- to be wrap around). Found by clang test suggested by Sean
- McBride.
-

-
-2011-11-27 Werner Lemberg <wl@gnu.org>
-
- [bdf] Fix Savannah bug #34896.
-
- ENCODING now covers the whole Unicode range.
-
- Note, however, that this change is quite expensive since it
- increases the size of three arrays by almost 400kByte in total. The
- right fix is to replace the logic with something smarter.
- Additionally, there exist very old BDFs for three-byte CCCII
- encoding which exceeds the range of Unicode (another reason to have
- a smarter logic).
-
- * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
- arrays.

-
-2011-09-11 Tomas Hoger <thoger@redhat.com>
-
- Slightly improve LZW_CLEAR handling.
-
- * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
- Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
- handled as clear codes. This also re-sets old_code and old_char to
- predictable values, which is a little better than using `random'
- ones if the code following LZW_CLEAR is invalid.
-
-2011-09-11 Tomas Hoger <thoger@redhat.com>
-
- Add explicit LZW decompression stack size limit.
-
- Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
- constructed correctly. It's even less than that, see e.g.
- libarchive code comment for a better size upper bound:
-
- http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
-
- This patch adds explicit stack size limit, enforced when stack is
- realloced.
-
- An alternative is to ensure that code < state->prefix[code - 256]
- when traversing prefix table. Such check is less efficient and
- should not be required if prefix table is constructed correctly in
- the first place.
-
- * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
-
-2011-09-11 Tomas Hoger <thoger@redhat.com>
-
- Protect against loops in the prefix table.
-
- LZW decompressor did not sufficiently check codes read from the
- input LZW stream. A specially-crafted or corrupted input could
- create a loop in the prefix table, which leads to memory usage
- spikes, as there's no decompression stack size limit.
-
- * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
- code in valid LZW stream must be 0..255.
- <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
- code > free_ent is invalid.

-
- [ftstroke] Major revision.
-
- The main problems
- -----------------
-
- o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
- joins (not bevel joins) were generated. Indeed, the meanings of
- `miter' and `bevel' were incorrectly reversed (consistently) in
- both the code and comments.
-
- o The way bevel joins were constructed (whether specified
- explicitly, or created as a result of exceeding the miter limit)
- did not match what is required for stroked text in PostScript or
- PDF.
-
- The main fixes
- --------------
-
- o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
-
- o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
- introduced to support PostScript and PDF miter joins.
-
- o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
- alias for FT_STROKER_LINEJOIN_MITER.
-
- Additionally, a variety of stroking errors have been fixed. These
- would cause various artifacts (including points `at infinity'),
- especially when stroking poor quality fonts.
-
- See
-
- http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
-
- for example documents. The FreeType stroker now produces results
- very similar to that produced by GhostScript and Distiller for these
- fonts.
-
- Other problems
- --------------
-
- The following problems have been resolved:
-
- o Inside corners could be generated incorrectly. Intersecting the
- inside corner could cause a missing triangular area and other
- effects.
-
- The intersection point can only be used if the join is between
- two lines and both lines are long enough. The `optimization'
- condition in `ft_stroker_inside' has been corrected; this
- requires the line length to be passed into various functions and
- stored in `FT_StrokerRec'.
-
- o Incorrect cubic curves could be generated. The angle
- calculations in `FT_Stroker_CubicTo' have been corrected to
- handle the case of the curve crossing the +/-PI direction.
-
- o If the border radius was greater than the radius of curvature of
- a curve, then the negative sector would end up outside (not
- inside) the border. This situation is now recognized and the
- negative sector is circumnavigated in the opposite direction.
- (If round line joins are being used, this code is disabled
- because the line join will always cover the negative sector.)
-
- o When a curve is split, the arcs may not join smoothly (especially
- if the curve turns sharply back on itself). Changes in
- direction between adjacent arcs were not handled. A round
- corner is now added if the deviation from one arc to the next is
- greater than a suitable threshold.
-
- o The current direction wasn't retained if a the outline contained
- a zero length lineto or a curve that was determined to be
- `basically a point'. This could cause a spurious join to be
- added.
-
- o Cubics with close control points could be mishandled. All eight
- cases are now distinguished correctly.
-
- Other improvements
- ------------------
-
- o Borders for cubic curves could be too `flat'.
- FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
- this.
-
- o The handling and use of movable points has been simplified a
- little.
-
- o Various values are now computed only if the results are actually
- needed.
-
- o The directions of the outer and inner borders have been swapped,
- as recommended by Graham Asher.

-
- [raster] Reduce jitter value.
-
- This catches a rendering problem with glyph `x' from Tahoma at
- 10ppem. It seems that the increase of the precision in the change
- from 2009-06-11 makes a larger jitter value unnecessary.
-
- * src/raster/ftraster.c (Set_High_Precision): Implement it.
-
-2011-01-13 Werner Lemberg <wl@gnu.org>
-
- [raster] Handle drop-outs at glyph borders according to Microsoft.
-
- If a drop-out rule would switch on a pixel outside of the glyph's
- bounding box, use the right (or top) pixel instead. This is an
- undocumented feature, but some fonts like `Helvetica Neue LT Com 65
- Medium' heavily rely on it.
-
- Thanks to Greg Hitchcock who explained this behaviour.

-
- [cache] Fix Savannah bug #31923, patch drafted by Harsha.
-
- When a node comparator changes the cached nodes during the
- search of a node matching with queried properties, the
- pointers obtained before the function should be updated to
- prevent the dereference to freed or reallocated nodes.
- To minimize the rescan of the linked list, the update is
- executed when the comparator notifies the change of cached
- nodes. This change depends previous change:
- 38b272ffbbdaae276d636aec4ef84af407d16181
-
- * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
- top node if the cached nodes are changed.
- * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Notice if a cache query induced the node list change.
-
- Some node comparators (comparing the cache node contents and the
- properties specified by the query) can flush the cache node to
- prevent the cache inflation. The change may invalidate the pointers
- to the node obtained before the node comparison, so it should be
- noticed to the caller. The problem caused by the cache node
- changing is reported by Harsha, see Savannah bug #31923.
-
- * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
- `FT_Bool* list_changed' to indicate the change of the cached nodes
- to the caller.
- (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
- `_list_changed'.
- (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
- and update it when `FTC_Manager_FlushN' flushes any nodes.
-
- * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
- FTC_Node_CompareFunc type.
- (ftc_gnode_compare): Ditto.
-
- * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes (anyway, it
- is always FALSE).
-
- * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (ftc_cmap_node_remove_faceid): Ditto.
-
- * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
- `FTC_CACHE_TRYLOOP_END', because the result is not needed.
- (FTC_Cache_Lookup): Watch the change of the cache nodes by
- `list_changed'.
- (FTC_Cache_RemoveFaceID): Ditto.
-
- * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
- TRUE/FALSE macros.
- (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
- indicate the change of the cache nodes (anyway, it is always FALSE).
- (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_gnode_compare'.
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
-
- * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
- list_changed' to indicate the change of the cache nodes, anyway. It
- is updated by `FTC_CACHE_TRYLOOP'.
- (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
- passed to `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
-
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
- argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
- prototype.
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
- `cache' is not used by its child `ftc_gnode_compare'.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Deduplicate the code to get the top node by a hash.
-
- There are several duplicated code fragments getting the top node
- from a cache by a given hash, like:
-
- idx = hash & cache->mask;
- if ( idx < cache->p )
- idx = hash & ( cache->mask * 2 + 1 );
- pnode = cache->buckets + idx;
-
- To remove duplication, a cpp-macro to do same work
- `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
- configuration, non-`ftc_get_top_node_for_hash' is also introduced.
-
- * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
- and implement inlined version.
- (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
- * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
- version.
- (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
- (ftc_node_hash_link): Ditto.
- (FTC_Cache_Lookup): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] inline-specific functions are conditionalized.
-
- * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
- inlined configuration. This function is a thin wrapper of
- `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
- `nodecmp' argument). Under non-inlined configuration,
- `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
- `FTC_Cache->clazz.node_compare'.
-
- * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
- * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
- `ftc_snode_compare'.
- * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
-
-2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Correct a type mismatch under non-inlined config.
-
- * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
- takes the node via a pointer `FTC_Node*', differently from cpp-macro
- `FTC_CACHE_LOOKUP_CMP'.

-
- * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
-
- SYSTEM_ZLIB is used to switch the builtin zlib source
- or system zlib source out of FreeType2. But ftbzip2
- module has no builtin bzip2 library and always requires

-2010-12-25 Harsha <mm.harsha@gmail.com>
-
- Apply Savannah patch #7422.
-
- If we encounter a space in a string then the sbit buffer is NULL,
- height and width are 0s. So the check in ftc_snode_compare will
- always pass for spaces (comparison with 255). Here the comments
- above the condition are proper but the implementation is not. When
- we create an snode I think it is the proper way to initialize the
- width to 255 and then put a check for being equal to 255 in snode
- compare function.
-
- * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
- value 255.
- (ftc_snode_compare): Fix condition.

- [ftsmooth] Improve rendering.
-
- * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
- cubic deviations have been estimated _after_ UPSCALE, whereas
- conic ones have been evaluated _before_ UPSCALE, which produces
- inferior rendering results. Fix this.
- Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has
- been tested with demo images sent to the mailing list. See
-
- http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html

- to original FT_UFast, to match with FT_CacheRec.
-
-2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [cache] Change the hash types to FT_PtrDist.
-
- On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
- variables are inappropriate to calculate hash values
- from the memory address (64-bit). The hash variables
- are extended from FT_ULong to FT_PtrDist and new
- hashing macro functions are introduced. The hash
- values on 16-bit memory platforms are changed, but
- ILP32 and LP64 are not changed. The hash value in
- the cache subsystem is not reverted to the memory
- address, so using signed type FT_PtrDist is safe.
-
- * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
- function to replace `FTC_FACE_ID_HASH' for portability.
- * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
- `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
- * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
-
- * src/cache/ftccache.h (FTC_NodeRec): The type of the

-
- [cache] Hide internal macros incompatible with LLP64.
-
- `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
- `FTC_IMAGE_TYPE_HASH' are enclosed by
- FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
- normal clients.
-

-
- Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
-
- On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
- cannot cover the memory address (64-bit). `FT_MEM_VAL' is
- used for hashing only and not dereferred, so using signed
- type FT_PtrDist is safe.
-
- * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
- return value from FT_ULong to FT_PtrDist.
- (ft_mem_table_resize): The type of hash is changed to
- FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
-

-
- Replace "%lx" for memory address by "%p", LLP64 platforms.
-
- On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
- the memory address (64-bit). Also the casts from the pointer
- type to long int should be removed to preserve the address
- correctly.

- * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
- (End_Profile) Ditto.
- * src/truetype/ttinterp.c (Init_Context): Ditto.

-
- [raccess] Skip unrequired resource access rules by Darwin VFS.
-
- When a resource fork access rule by Darwin VFS could open the
- resource fork but no font is found in it, the rest of rules
- by Darwin VFS are skipped. It reduces the warnings of the
- deprecated resource fork access method by recent Darwin kernel.
- Fix MacPorts ticket #18859:
- http://trac.macports.org/ticket/18859
-
- * src/base/ftobjs.c (load_face_in_embedded_rfork):
- When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
- means that the file is possible to be `fopen'-ed but zero-sized.
- Also there is a case that the resource fork is not zero-sized,
- but no supported font exists in it. If a rule by Darwin VFS
- falls into such cases, there is no need to try other Darwin VFS
- rules anymore. Such cases are marked by vfs_rfork_has_no_font.
- If it is TRUE, the Darwin VFS rules are skipped.
-
-2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [raccess] Grouping resource access rules based on Darwin VFS.
-
- MacOS X/Darwin kernel supports a few tricky methods to access
- a resource fork via ANSI C or POSIX interface. Current resource
- fork accessor tries all possible methods to support all kernels.
- But if a method could open a resource fork but no font is found,
- there is no need to try other methods older than tested method.
- To determine whether the rule index is for Darwin VFS, a local
- function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
- To use this function in ftobjs.c etc but it should be inlined,
- it is exposed by ftbase.h.
-
- * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
- the rules to access the resource fork.
- (raccess_guess_rec): New structure to bind the rule function and
- rule enum type.
- (FT_Raccess_Guess): The list of the rule functions is replaced by
- (raccess_guess_table): This. This is exposed to be used by other
- intra module functions.
- (raccess_rule_by_darwin_vfs): A function to return a boolean
- if the rule specified by the rule index is based on Darwin VFS.

-
- Prevent to open a FT_Stream for zero-sized file on non-Unix.
-
- builds/unix/ftsystem.c prevents to open an useless stream from
- zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
- stream drivers for ANSI C, Amiga and VMS return useless streams.
- For cross-platform consistency, all stream drivers should act
- same.
-
- * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
- file is zero, FT_Err_Cannot_Open_Stream is returned.
- * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
- * src/vms/ftsystem.c (FT_Stream_Open): Ditto.

-
- [psaux] Fix Savannah bug #29846.
-
- Previously we discovered fonts which used `setcurrentpoint' to set
- the initial point of a contour to 0,0. This caused FreeType to
- raise an error, because the `setcurrentpoint' operator is only
- supposed to be used with the results from an OtherSubr subroutine.
-
- This was fixed by simply ignoring the error and carrying on.
-
- Now we have found a font which uses setcurrentpoint to actually
- establish a non-zero point for a contour during the course of a
- glyph program. FWIW, these files may be produced by an application
- called `Intaglio' on the Mac, when converting TrueType fonts to
- Type 1.
-
- The fix allows the new invalid behaviour, the old invalid behaviour
- and real proper usage of the operator to work the same way as Adobe
- interpreters apparently do.
-
- * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
- `setcurrentpoint' use the top two elements of the stack to establish
- unconditionally the current x and y coordinates.
-
- Make the `flex' subroutine handling (OtherSubr 0) put the current
- x,y coordinates onto the stack, instead of two dummy uninitialised
- values.
-

- and others.

-2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [otvalid] Fix a naming convention conflicting with ftvalid.
-
- Some prototypes in ftvalid.h use `valid' for the variables
- typed as FT_Validator. Their implementations in src/base/
- ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
-
- Some macros in otvcommn.h assume the exist of the variable
- `valid' typed as OTV_Validator in the caller.
-
- Mixing these two conventions cause invalid pointer conversion
- and unexpected SEGV in longjmp. To prevent it, all variables
- typed as OTV_Validator are renamed to `otvalid'.
-
- * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
- * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,

-
- Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'

-
- [autofit] Better fix for conversion specifiers in debug messages.
-
- Using `%ld' for pointer differences causes warnings on 32bit

-
- This patch improves the change from 2014-11-28.
-
- * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
- pointer differences are always sufficiently small.

- eliminating the hack with an empty, full-width `<td>' element
- inbetween.
-
- The change also enforces the same (smaller) size for all index and
- TOC links.

-
- [Savannah bug #43682] Add/remove `void' casts to some functions.
-

-
- [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
-
- Don't cast cmap init function pointers to an incompatible type.
-
- Without this patch, the number of parameters between declaration and
- the real signature differs. Calling such a function results in
- undefined behavior.
-
- ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
- 6.5.2.2 Function calls
- 9 If the function is defined with a type that is not
- compatible with the type (of the expression) pointed to by
- the expression that denotes the called function, the
- behavior is undefined.
-
- On certain platforms (c -> js with emscripten) this causes
- termination of execution or invalid calls because in the emscripten
- implementation, function pointers of different types are stored in
- different pointer arrays. Incorrect pointer type here results in
- indexing of an incorrect array.

-
- Avoid compiler warnings on x86-64 for `FT_MulFix'.
-
- `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
- but several inline implementations of it in `ftcalc.h' take
- `FT_Int32' arguments. This is causing compiler warnings on x86-64:
- If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
- inline implementation of this function, integer values are truncated
- from 64bit to 32bit.

- [base] CORDIC improvements.
-
- The scaling between the hypotenuse and its CORDIC approximation is
- based on regression analysis. The smaller padding for `theta' is

- * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.
-
- Before this patch, it was impossible to ever call DELTAP[123] in
- subpixel hinting mode as described in the ClearType whitepaper; it
- only worked if in `compatibility mode'. However, compatibility mode
- essentially disables SHPIX, completely ruining hinting of
- ttfautohint output, for example.
-
- We now follow the whitepaper more closely so that DELTAP[123]
- instructions for touched points in the non-subpixel direction are
- executed.

-
- [autofit] Fix Savannah bug #42148.
-
- The adaptation of the cjk auto-hinter module to blue stringsets in
- 2013-08-25 had three severe bugs. Mea culpa.
-
- 1. Contrary to the latin auto-hinter, characters for reference and
- overshoot values of a blue zone are specified separately. Due to
- the screwed-up change it didn't work at all.
-
- 2. A boolean comparison was erroneously replaced with a cast,
- causing invalid results with the `^' operator later on. The
- visual artifact caused by this problem is the topic of the bug
- report.
-
- 3. Two flag values were inverted, causing incorrect assignment of
- reference and overshoot values.
-
- * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
- syntax to have both reference and overshoot characters in a single
- string. This is error #1.
- Add extensive comments.
-
- * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
- longer used.
- (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
- This is error #3.
-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
-
- * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
- Use character `|' to separate characters for reference and overshoot
- values.
- Improve tracing messages, synchronizing them with the latin
- auto-hinter.
- (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
- This is error #2.
- (af_cjk_align_linked_edge): Add tracing message.
-
- * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
- used.
-
-2014-04-17 Werner Lemberg <wl@gnu.org>
-
- [autofit] More coverage fixes for complex scripts.
-
- * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage
- of GSUB lookups into output coverage. Otherwise, ligatures are not
- handled properly.
- Don't check blue zone characters for default coverage.
-
-2014-04-17 Werner Lemberg <wl@gnu.org>

-
-2014-04-12 Werner Lemberg <wl@gnu.org>
-
- [autofit] Redesign the recognition algorithm of strong points.
-
- In particular, local extrema without horizontal or vertical segments
- are better recognized:
-
- + A + D
- \ /
- \ /
- \ /
- \ /
- \ + C
- \ /
- B +/
-
- If the distances AB and CD are large, point B wasn't previously
- detected as an extremum since the `ft_corner_is_flat' function
- `swallowed' BC regardless of its direction, tagging point B as weak.
- The next iteration started at B and made `ft_corner_is_flat' swallow
- point C, tagging it as weak also, et voilà.
-
- To improve that, another pass gets now performed before calling
- `ft_corner_is_flat' to improve the `topology' of an outline: A
- sequence of non-horizontal or non-vertical vectors that point into
- the same quadrant are handled as a single, large vector.
-
- Additionally, distances of near points are now accumulated, which
- makes the auto-hinter handle them as if they were prepended to the
- next non-near vector.
-
- This generally improves the auto-hinter's rendering results.
-
- * src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
-
- * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
- `AF_FLAG_NEAR'.
-
-2014-04-05 Werner Lemberg <wl@gnu.org>
-
- [autofit] Improve scoring algorithm for identifying stems.
-
- Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
-
- The new algorithm takes care of the width of stems: If the distance
- between two segments is larger than the largest stem width, the
- demerits quickly increase for larger distances. This improves
- hinting of slanted fonts (especially if the inner parts of serifs
- have non-horizontal `shoulders'), avoiding false stem links.
-
- * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
- stem width (if available) to compute better demerits for distances
- between stems.
- (af_latin_hints_detect_features): Pass stem width array and array
- size.
- (af_latin_metrics_init_widths): Updated to use original algorithm.
- (af_latin_hints_apply): Updated to use new algorithm.

- [bdf] Fix Savannah bug #41692.
-
- bdflib puts data from the input stream into a buffer in chunks of
- 1024 bytes. The data itself gets then parsed line by line, simply
- increasing the current pointer into the buffer; if the search for
- the final newline character exceeds the buffer size, more data gets
- read.
-
- However, in case the current line's end is very near to the buffer
- end, and the keyword to compare with is longer than the current
- line's length, an out-of-bounds read might happen since `memcmp'
- doesn't stop properly at the string end.
-
- * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
- stop at string ends.

- [autofit] Fix Indic scripts.
-
- Split the single, incorrect Indic entry into separate scripts so
- that the covered ranges are the same: Bengali, Devanagari, Gujarati,
- Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
- Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
- entries for Meetei Mayek and Sharada – the Unicode ranges were
- incorrect (and nobody has complained about that), fonts are scarce
- for those scripts, and the Indic auto-hinter support is rudimentary
- anyways.
-
- * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
- AF_CONFIG_OPTION_CJK.
-
- * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.

- auxiliary macros; use them to define styles for Cyrillic, Greek, and

-
- * src/autofit/afcover.h: Remove coverage for oldstyle figures.
- Since those digits are used in combination with ordinary letters, it

-2013-12-30 Werner Lemberg <wl@gnu.org>
-
- [autofit] Don't combine multiple features into one set.
-
- Combining them, as originally envisioned, would lead to much more

- large number of scripts currently.

- [ftrfork] Fix the face order difference between POSIX and Carbon.
-
- The fragmented resources in Suitcase and .dfont should be reordered
- when `POST' resource for Type1 is being restored, but reordering of
- sfnt resources induces the different face order. Now the ordering
- is restricted to `POST' resource only, to prevent the different
- order issue (e.g. the face index in the fontconfig cache generated
- with Carbon framework is incompatible with that by FreeType 2
- without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

-
- [autofit] Introduce `coverages'.
-
- Coverages are the interface to the HarfBuzz library to access
- OpenType features for handling glyphs not addressable by the cmap.
-
- Right now, compilation of HarfBuzz is only added to the development
- build. A solution for standard build mode will be delayed until
- HarfBuzz gets split into two libraries to avoid mutual dependencies
- between FreeType and HarfBuzz.
-
- Note that this is only a first step in handling coverages, basically
- providing the framework only. Code for handling selected OpenType
- features (this is, actually using the data in `afcover.h') will
- follow.

-
- Simplify header file hierarchy.
-
- This large patch changes the header file directory layout from
- `include/freetype/...' to `include/...', effectively removing one
- level. Since the file `ft2build.h' is also located in `include'
- (and it stays there even after installation), all FreeType header
- files are now in a single directory.
-
- Applications that use (a) `freetype-config' or FreeType's
- `pkg-config' file to get the include directory for the compiler, and
- (b) the documented way for header inclusion like
-
- #include <ft2build.h>
- #include FT_FREETYPE_H
- ...
-
- don't need any change to the source code.
-

- * builds/unix/install.mk (install): No longer try to remove `cache'
- and `internal' subdirectories; instead, remove the `freetype'
- subdirectory.

-2013-11-01 Werner Lemberg <wl@gnu.org>
-
- [truetype] Minor code refactoring.
-
- Two benefits: The allocated FDEF (and IDEF) array gets slightly
- smaller, and the `ttdebug' demo program has access to function
- numbers without additional costs.
-
- Fortunately, no changes to FontForge are necessary – this is the
- only external TrueType debugger I know of, but others may exist and
- should check the code accordingly.
-
- * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and
- `Cur_End' with a pointer to the corresponding `TT_DefRecord'
- structure.
-

-
- * include/freetype/tttables.h (TT_OS2): Add fields

- [arm] Fix thumb2 inline assembly under LLVM.
-
- When using `ADD' with an immediate operand, the instruction is
- actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
- immediate operand cannot exceed 4095. It will fail to compile with
- LLVM.
-
- However, in GCC, due to some legacy compatibility considerations,
- `ADD.W' will be automatically emitted when the immediate operand is
- larger than 4095.

- * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
-
- Note that the old code avoided using a region of the piecewise

- incorrect amount of darkening.

-
- This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
- is to use a previous darkening amount when producing an unhinted,
- unscaled outline. This can cause autohint samples in ftgrid and
- ftview to be based on darkened CFF outlines instead of unhinted,
- undarkened ones.
-

-
- Fix Savannah bug #39295.
-
- The bug was caused by switching to the initial hintmap (the one in
- effect when `moveto' executes) just before drawing the final element
- in the charstring. This ensured that the path was closed (in both
- Character Space and Device Space). But if the final element was a
- curve and if the final hintmap was different enough from the initial
- one, then the curve was visibly distorted.
-
- The first part of the fix is to draw the final curve using the final
- hintmap as specified by the charstring. This corrects the
- distortion but does not ensure closing in Device Space. It may
- require the rasterizer to automatically generate an extra closing
- line. Depending on the hintmap differences, this line could be from
- zero to a couple pixels in length.
-
- The second part of the fix covers the case where the charstring
- subpath is closed with an explicit line. We now modify that line's
- end point to avoid the distortion.
-
- Some glyphs in the bug report font (TexGyreHeros-Regular) that show
- the change are:
-
- 25ppem S (98)
- 24ppem eight (52)
- 25.5ppem p (85)
-
- Curves at the *end* of a subpath are no longer distorted. However,
- some of these glyphs have bad hint substitutions in the middle of a
- subpath, and these are not affected.
-
- The patch has been tested with a set of 106 fonts that shipped with
- Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
- Google Fonts. There are 1.5 million glyphs, of which some 20k are
- changed with the fix. A sampling of a few hundred of these changes
- have been examined more closely, and the changes look good (or at
- least acceptable).

- (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
- particular, shift the detection of zero-length lines from character
- space to device space.
- (cf2_glyphpath_closeOpenPath): Remove assertion.

-
- [autofit] Introduce data file for blue strings.
-
- The idea is to have a central file which gets processed by a Perl
- script to create proper `.c' and `.h' files using templates. There
- are two other reasons to do that:
-
- . The data file should be easily readable. We use UTF-8 encoding
- which then gets converted to single bytes.
-
- . Since the number of supported scripts will increase soon, the
- current usage of blue string arrays is a waste of space. Using
- the Perl script it is possible to imitate jagged arrays,
- defining enumeration constants as offsets into the arrays.
-
- This commit only adds files without changing any functionality.
-
- * src/autofit/afblue.dat: New data file.
- * src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

- [autofit] Introduce `writing systems'.
-
- This patch adds a new top level to the auto-hinter's script class
- hierarchy. It defines `writing systems' which can contain multiple
- scripts.
-
- For example, the `latin' writing system (in file `aflatin.c') is
- able to support scripts like Latin, Cyrillic, Armenian, etc., which
- can be handled similarly.

-
- Speed up ARMv7 support.
-
- When building for ARMv7 with thumb2 instructions, the optimized
- `FT_MulFix_arm' assembly routine was not being used.
-
- The reason for this is in the `ftconfig.h' header, namely:
-
- - The assembly routine uses the `smull' instruction which is not
- available when generating Thumb-1 machine code. It is available
- in Thumb-2 mode, though.
-
- - The header was written a long time ago before Thumb-2 became
- widely popular (e.g. with Android). So it simply doesn't use the
- assembly routine if the `__thumb__' built-in macro is defined.
-
- - When compiling in Thumb-2 mode, the compiler will define both
- `__thumb__' and `__thumb2__'.
-
- By checking for `(__thumb2__ || !__thumb__)', we ensure that the
- assembly routine is only avoided when generating Thumb-1 code.
-
- Given that this is performance-sensitive function, this improves
- `ftbench' as follows on a Galaxy Nexus:

- Apply fixes for cppcheck nitpicks.
-
- http://cppcheck.sourceforge.net/
-
- The call was (from the top-level of the FreeType tree):
-
- cppcheck --force \
- --enable=all \
- -I include \
- -I include/freetype/ \
- -I include/freetype/config/ \
- -I include/freetype/internal/ \
- . &> cppcheck.log
-
- Note that the current version heavily chokes on FreeType, delivering
- many wrong results. I will report those issues to the cppcheck team
- so that a newer version gives improved results hopefully.
-
- */* Improve variable scopes.
- */* Remove redundant initializations which get overwritten.
-
- * src/base/ftmac.c, builds/mac/ftmac.c (count_faces_scalable):

-
- Add support for color embedded bitmaps (eg. color emoji).
-
- A new load flag, FT_LOAD_COLOR, makes FreeType load color
- embedded-bitmaps, following this draft specification
-
- https://color-emoji.googlecode.com/git/specification/v1.html
-
- which defines two new SFNT tables, `CBDT' and `CBLC' (named and
- modeled after `EBDT' and `EBLC', respectively). The color bitmaps
- are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
- pre-multiplied sRGB images. If PNG support is available, PNG color
- images as defined in the same proposed specification are supported
- also.

- [smooth] Sub-banding protocol revision.
-
- Rasterization sub-banding is utilized at large sizes while using a
- rather small fixed memory pool. Indeed it is possible to make an
- educated guess how much memory is necessary at a given size for a
- given glyph. It turns out that, for a large majority of European
- glyphs, you should store about 8 times more boundary pixels than
- their height. Or, vice versa, if your memory pool can hold 800
- pixels the band height should be 100 and you should sub-band
- anything larger than that. Should you still run out of memory,
- FreeType bisects the band but you have wasted some time. This is
- what has been implemented in FreeType since the beginning.
-
- It was overlooked, however, that the top band could grow to twice
- the default band size leading to unnecessary memory overflows there.
- This commit fixes that. Now the bands are distributed more evenly
- and cannot exceed the default size.
-
- Now the magic number 8 is really suitable for rather simple European
- scripts. For complex Chinese logograms the magic number should be
- 13 but that is subject for another day.

-
- [autofit] Fix compilation with VS2016 (#48126).
-
- This compiler doesn't recognize the end-of-comment sequence `*/' if
- it immediately follows non-ASCII characters.
-
- * src/autofit/afscript.h: Ensure whitespace before `*/'.
-
-2016-06-04 Werner Lemberg <wl@gnu.org>
-
- Fix a test for named instances (#48122).
-

-2016-05-31 Nikolaus Waxweiler <madigens@gmail.com>
-
- [truetype] Let SHPIX move points in the twilight zone in v40.
-
- * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
- the twilight zone. Otherwise, treat SHPIX the same as DELTAP.
- Unbreaks various fonts such as older versions of Rokkitt and DTL
- Argo T Light that would glitch severely after calling ALIGNRP after a

-
- [type42] Support `CharStrings' entry format as created by LilyPond.
-
- * src/type42/t42parse.c (t42_parse_charstrings): Handle entries
- having the format
-
- (foo) cvn 12345 def
-
-2016-05-28 Werner Lemberg <wl@gnu.org>
-
- * src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
-
- Suggested by Alexei. `UL' is only needed for 16bit compilers, but
- it seems noone is using this anymore (and we no longer test whether
- FreeType compiles in such an environment). Otherwise, it is easy to
- add the postfix to the `AF_UNICODE_RANGE' macro.
-
-2016-05-26 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [smooth] Shrink bisection stack.
-
- The convergence of Bézier flatteners is fast with the deviation
- from straight line being asymptotically cut 4-fold on each bisection.
- This justifies smaller bisection stack size.
-
- * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
- (gray_render_conic): Create and use conic `bez_stack'. Move back the
- band analysis from...
- (gray_conic_to): ... here.
- (gray_render_cubic): Create and use cubic `bez_stack'. Move back the
- band analysis from...
- (gray_cubic_to): ... here.
- (gray_move_to): Updated.

- * src/autofit/afstyles.h: Add Armenian data.
-
-2016-05-23 Werner Lemberg <wl@gnu.org>
-
- * builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
-
- This was commented about 10 years ago – I think the reason then to
- disable libtool's `-export-symbols' option was to give some badly
- programmed applications access to internal FreeType functions.
-
- I believe that we should no longer take care of such programs; the
- number of symbols exported should be rather restricted as much as
- possible.
-
-2016-05-22 Werner Lemberg <wl@gnu.org>
-
- [autofit] Add blue-zone support for Gurmukhi script.

-
- * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

- data out of AF_CONFIG_OPTION_INDIC block.
-
- * src/autofit/afranges.c: Move Gurmukhi data out of
- AF_CONFIG_OPTION_INDIC block.
-
- * src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
- AF_WRITING_SYSTEM_LATIN.
-
-2016-05-21 Werner Lemberg <wl@gnu.org>
-
- Minor clang++ fixes.
-
- * src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c

-
-2016-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
-
- [truetype] Improve the recursive reference detector.
-
- The previous fix for #46372 misunderstood a composite glyph referring
- same component twice as a recursive reference. See the discussion
-
- http://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html
-
- Thanks to Khaled Hosny for finding this issue.
-
- * src/truetype/ttgload.c (ft_list_get_node_at): A function to get
- the i-th node from FT_List.
- (load_truetype_glyph): In the traversal scan of the reference tree
- in the composite glyph, we clear the nodes filled by previous
- sibling chain.
-
-2016-05-07 Werner Lemberg <wl@gnu.org>
-
- [cache] Allow value 0 for face ID.
-
- We never dereference `face_id', and some implementations might use a
- running number instead of a pointer. Additionally, disallowing
- value zero was undocumented.
-
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c
- (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for
- `face_id'.
-
-2016-05-05 Alexei Podtelezhnikov <apodtele@gmail.com>
-
- [smooth] More efficient accounting of conic splits and draws.
-
- A single decrement counter of segments to draw, instead of an array,
- contains all the information necessary to decide when to split and
- when to draw a conic segment. The number of splits before each draw is
- equal to the number of trailing zeros in the counter.
-
- * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.
- (gray_render_conic): Updated to use decrement counter of segments.
-
-2016-05-05 Werner Lemberg <wl@gnu.org>
-
- [cff, truetype] Fix logic for `FT_Property_Set'.
-
- Otherwise some properties could be set to arbitrary values, which is
- harmless, but querying could give wrong positive results.
-
- * src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
- * src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
- Only allow defined values.
-

-
- [cmake] Honor SKIP_INSTALL_* settings (as used in zlib).
-
- As FreeType depends on zlib, if we don't install zlib (e.g., because
- we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too
- (cmake triggers an error saying that FreeType cannot be installed

-
- [autofit] Add support for Georgian scripts.
-
- Georgian is problematic, since `uppercase' forms of Mkhedruli
- (called Mtavruli) are not yet defined in Unicode, which means that
- proper blue zones can't be defined. However, there is already a
- proposal submitted to Unicode; see
-
- http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
-
- Additionally, due to historical reasons, Unicode treats Khutsuri as
- the same script as Mkhedruli, and so does OpenType. However, since
- the two scripts have completely different shapes it can happen that
- blue zones differ considerably. The tag `geok' used here (derived
- from ISO 15924) to differentiate the two scripts is not an OpenType
- tag in use. If we now have a font that contains both glyphs for
- Mkhedruli and Khutsuri, and it uses OpenType features for both also,
- HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
- blue zones for `geok' are not used for glyphs involved in the
- OpenType features.
-
- An issue not yet resolved is which OpenType feature should be used
- to access Mtavruli glyph shapes; right now, FreeType doesn't set up
- support for them, but it is easy to add them later on as soon as
- more information is available.

-
- [autofit] Fix handling of default script.
-
- Patch taken from ttfautohint, commit
- 071ae2c00e0d67f9d19418f4fade1c23d27dc185.
-
- There were two bugs.
-
- - We now use non-standard script tags like `khms' for special
- purposes. However, HarfBuzz maps such tags to `DFLT', and
- without this commit the associated lookups were incorrectly
- assigned to the non-standard tags.
-
- - Let's assume we have a Bengali font, and the font's `DFLT'
- script tag handles the necessary lookups for Bengali, too.
- Without this commit, the `DFLT' lookups were assigned to
- ttfautohint's default script (usually `latn') before the
- standard lookups for Bengali were handled.
-
- We now have the following order while searching for covered
- glyph indices.
-
- special features of scripts (e.g. `sups' for Cyrillic)
- Unicode mappings of scripts
- remaining features of scripts (especially important for Indic
- scripts)
- default features of default script
-
- * src/autofit/afshaper.c, src/autofit/afshaper.h
- (af_shaper_get_coverage): Add boolean parameter to indicate default
- script.
- Update all callers.

-
- [autofit] Introduce subscript top blue zones.
-
- This feature is mainly for Khmer: The idea is to avoid a clash

-
- [autofit] Rewrite HarfBuzz interface to support character clusters.
-
- Scripts like Khmer have blue zones that can't be directly
- represented by Unicode characters. Instead, it is necessary to let
- HarfBuzz convert character clusters into proper glyph representation
- forms, then deriving the blue zone information from the resulting
- glyphs.
-
- * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
- * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
- files, providing a new API to access HarfBuzz.
-
- The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
- and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded
- string with function `af_shaper_get_cluster', and the resulting
- glyph data (indices, advance widths, vertical offsets) can be
- iteratively accessed with function `af_shaper_get_elem'.

- [smooth] Faster alternative line renderer.
-
- This implementation renders the entire line segment at once without
- subdividing it into scanlines. The main speed improvement comes from
- reducing the number of divisions to just two per line segment, which
- is a bare minimum to calculate cell coverage in a smooth rasterizer.
- Notably, the progression from cell to cell does not itself require any
- divisions at all. The speed improvement is more noticeable at larger
- sizes.

-
- While the current code in `FT_Get_Next_Char' correctly rejects

- [sfnt] Improve handling of invalid SFNT table entries (#45987).
-
- This patch fixes weaknesses in function `tt_face_load_font_dir'.
-
- - It incorrectly assumed that valid tables are always at the
- beginning. As a consequence, some valid tables after invalid
- entries (which are ignored) were never seen.
-
- - Duplicate table entries (this is, having the same tag) were not
- rejected.
-
- - The number of valid tables was sometimes too large, leading to
- access of invalid tables.

- * src/sfnt/ttload.c (check_table_dir): Add argument to return number
- of valid tables.
- Add another tracing message.

-
- [autofit] Redesign code ranges (1/2).
-
- This patch introduces auxiliary code ranges that identify no-base
- characters; they refer to glyphs of a script that should be hinted
- without alignments to blue zones (mostly diacritics).
-
- It also splits off ranges for fallback scripts that handle subscript
- and superscript characters not covered by OpenType features. For
- example, this greatly helps improve the hinting of various phonetic
- alphabets, which contain a large amount characters that look like
- superscript glyphs.
-
- Finally, code ranges are updated to Unicode 8.0, and enclosed
- characters are removed in general since they normally look better if
- they stay unhinted.
-
- * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
- 8.0.
- Split off superscript-like and subscript-like glyphs into...
-
- (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
-
- (af_xxxx_nobase_uniranges): New arrays that hold no-base characters
- of the corresponding character ranges.

-
- [type42] Fix glyph access.
-
- This is a severe bug: We've missed one level of indirection, as
- described in the Type 42 specification. As a result, ftview
- sometimes showed incorrect glyphs for given glyph names, and even
- displayed `error 0x0006' (invalid argument!) in case the number of
- glyph indices differed between the Type 42 font and the embedded
- TTF.
-
- Apparently, noone ever noticed it; this shows how much Type 42 fonts
- are in use...

- * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index

-
- Fix Savannah bug #45097.
-
- We no longer `pollute' the namespace of possible header file names;
- instead we move `ft2build.h' up by one level so that it gets
- installed in the default include directory (e.g.,
- /usr/local/include). After this commit, only `ft2build.h' stays in
- the compiler's include path.
-
- No visible changes for the user who follows the standard FreeType
- header inclusion rules.
-
- * include/*: Move to ...
- * include/freetype2/*: This directory, except `ft2build.h'.

-
- Make Jam support work again.
-

- [truetype] Fix memory leak.
-
- Problem reported by Grissiom <chaos.proton@gmail.com>; in
-
- http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
-
- there is an example code to trigger the bug.
-
- * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
- data before allocating again. Bug most probably introduced four
- years ago in version 2.4.3.
-
-2015-06-02 Werner Lemberg <wl@gnu.org>
-
- [raster] Add more tracing.

- (TT_RunIns): Implement display of code position and stack.
-
-2015-05-31 Werner Lemberg <wl@gnu.org>
-
- [truetype] In GX, make private point numbers work correctly.
-
- This is completely missing in Apple's documentation: If a `gvar'
- tuple uses private point numbers (this is, deltas are specified for
- some points only), the uncovered points must be interpolated for
- this tuple similar to the IUP bytecode instruction. Examples that
- need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
-
- * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
- tt_handle_deltas): New functions.
- (TT_Vary_Get_Glyph_Deltas): Renamed to...
- (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
- points and does no longer return an array of deltas.
- Add tracing information.
- Call `tt_handle_deltas' to interpolate missing deltas.
- Also fix a minor memory leak in case of error.
-
- * src/truetype/ttgxvar.h: Updated.
-
- * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
- load_truetype_glyph): Updated.

-
- [truetype] Add tracing information to GX code.
-
- * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
- ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
- TT_Set_Var_Design, tt_face_vary_cvt): Do it.

- [truetype] Fix commit from 2015-05-22.
-
- * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code

-
-2015-05-23 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix return values of GETINFO bytecode instruction.
-
- * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
- `vertical_lcd' and `gray_cleartype'.
-
- * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
- Change `symmetrical smoothing' to TRUE, since FreeType produces
- exactly this.
-
- * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
- values for symmetrical smoothing, namely 11/18.
- Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
- (12/19).
-
-2015-05-23 Werner Lemberg <wl@gnu.org>
-
- [truetype] Minor.
-
- * src/truetype/ttinterp.h (TT_ExecContext):
- s/subpixel/subpixel_hinting.
-
- * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
-
-2015-05-22 Werner Lemberg <wl@gnu.org>
-
- [truetype] Support selector index 3 of the INSTCTRL instruction.
-
- This flag activates `native ClearType hinting', disabling backward
- compatibility mode as described in Greg Hitchcocks whitepaper. In
- other words, it enables unrestricted functionality of all TrueType
- instructions in ClearType.
-
- * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
- unconditionally.
- (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
- `GS.instruct_control' is active.
-
- * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
- (Ins_GETINFO): Updated.
-
- * docs/CHANGES: Document it.
-
-2015-05-20 Werner Lemberg <wl@gnu.org>

- [truetype] Minor.
-
- * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
- argument.
-
-2015-05-17 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix loading of composite glyphs.
-
- * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
- ARGS_ARE_XY_VALUES flag is not set, handle argument values as
- unsigned. I trust `ttx' (which has exactly such code) that it does
- the right thing here...
-
- The reason that noone has ever noticed this bug is probably the fact
- that point-aligned subglyphs are rare, as are subglyphs with a
- number of points in the range [128;255], which is quite large (or
- even in the range [32768;65535], which is extremely unlikely).
-
-2015-05-12 Chris Liddell <chris.liddell@artifex.com>
-
- [cff] Make the `*curveto' operators more tolerant.
-
- * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
- `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
- pulling values off the stack until the stack is exhausted.
- Implicitly the stack must be a multiple (or for subtly different
- behaviour) a multiple plus a specific number of extra values deep.
- If that's not the case, enforce it (as the old code did).
-
-2015-05-12 Chris Liddell <chris.liddell@artifex.com>
-
- [cff] fix incremental interface with new cff code.
-
- * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
- interface to retrieve glyph data for a SEAC, it be left to the
- incremental interface callback to apply the encoding to raw
- character index (as it was in the previous code).

-
- for a discussion.

-
- [raster] Fix Savannah bug #44022.
-
- Add fallback for glyphs with degenerate bounding boxes.
-
- If a glyph has only one very narrow feature, the bbox can end up
- with either the width or height of the bbox being 0, in which case
- no raster memory is allocated and no attempt is made to render the
- glyph. This is less than ideal when the drop-out compensation in
- the rendering code would actually result in the glyph being
- rendered.
-
- This problem can be observed with the `I' glyph (gid 47) in the
- Autodesk RomanS TrueType font.
-
- * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
- dimension is zero to explicitly round up/down (instead of simply
- round).
-
-2015-01-17 Werner Lemberg <wl@gnu.org>
-
- Add some tools to handle yearly copyright notice updates.
-
- We are now following the GNU guidelines: A new release automatically
- means that the copyright year of all affected files gets updated; it
- is no longer used to track years of modification changes.
-
- * src/tools/update-copyright-year: New Perl script.
- * src/tools/update-copyright: New shell script that calls
- `update-copyright-year' on all files.
- * src/tools/no-copyright: Exceptions that should not be handled by

-
- [autofit] Add embedded array of segments and edges.
-
- Avoids multiple mallocs per typical glyphs.
-
- With this and recent changes to avoid mallocs, the thread-safe
- stack-based loader is now as fast as the previous model that had one
- cached singleton.
-
- * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):
- New macros.
- (AF_AxisHintsRec): Add two arrays for segments and edges.
-
- * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate

- `AF_GlyphHints'.
- Update prototype.
-
- * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'
- parameter instead of `FT_Memory'.
- (af_loader_done): Directly reset `load_hints'.
- (af_loader_load_g): Updated.
-
- * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local
- `hints' object.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [autofit] Reuse slot glyph loader.
-
- No need to create a new glyph loader; we can reuse the one from
- `slot->internal->loader'. It's hard to tell why it was written that
- way originally, but new code looks sound and correct to me, and
- avoids lots of allocations.
-
- * src/autofit/afloader.c (af_loader_init): Change return type to
- `void'.
- Don't call `FT_GlyphLoader_New'.
- (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
- (af_loader_load_g): Update code to use `internal->loader', which
- doesn't need copying of data.
-
- * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
- Update prototype.
-
- * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [autofit] Remove (unused) support for composite glyphs.
-
- We never have to deal with composite glyphs in the autohinter, as
- those will be loaded into FORMAT_OUTLINE by the recursed
- `FT_Load_Glyph' function.
-
- In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
- FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
- FT_LOAD_NO_HINTING:
-
- /* resolve load flags dependencies */
-
- if ( load_flags & FT_LOAD_NO_RECURSE )
- load_flags |= FT_LOAD_NO_SCALE |
- FT_LOAD_IGNORE_TRANSFORM;
-
- if ( load_flags & FT_LOAD_NO_SCALE )
- {
- load_flags |= FT_LOAD_NO_HINTING |
- FT_LOAD_NO_BITMAP;
-
- load_flags &= ~FT_LOAD_RENDER;
- }
-
- and as such the auto-hinter is never called. Thus, the recursion in
- `af_loader_load_g' never actually happens. So remove the depth
- counter as well.
-
- * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
- parameter.
- <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
- (af_loader_load_glyph): Updated.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [raster] Fix uninitialized memory access.
-
- Apparently `ras.cProfile' might be uninitialized. This will be the
- case if `ras.top == ras.cProfile->offset', as can be seen in
- `End_Profile'. The overshoot code introduced in a change `Fix B/W
- rasterization of subglyphs with different drop-out modes.' (from
- 2009-06-18) violated this, accessing `ras.cProfile->flags'
- unconditionally just before calling `End_Profile' (which then
- detected that `cProfile' is uninitialized and didn't touch it).
-
- This was harmless, and was not detected by valgrind before because
- the objects were allocated on the `raster_pool', which was always
- initialized. With recent change to allocate raster buffers on the
- stack, valgrind now reported this invalid access.
-
- * src/raster/ftraster.c (Convert_Glyph): Don't access an
- uninitialized `cProfile'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [smooth] Fix uninitialized memory access.
-
- Looks like `ras.span_y' could always be used without initialization.
- This was never detected by valgrind before because the library-wide
- `raster_pool' was used for the worker object and `raster_pool' was
- originally zero'ed. But subsequent reuses of it were using `span_y'
- uninitialized. With the recent change to not use `render_pool' and
- allocate worker and buffer on the stack, valgrind now detects this
- uninitialized access.
-
- * src/smooth/ftgrays.c (gray_raster_render): Initialize
- `ras.span_y'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [base] Don't initialize unused `driver->glyph_loader'.
-
- * src/base/ftobjs.c (Destroy_Driver): Don't call
- `FT_GlyphLoader_Done'.
- (FT_Add_Module): Don't call `FT_GlyphLoader_New'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [base] Don't allocate `library->raster_pool' anymore.
-
- It's unused after the following commits:
-
- [raster] Allocate render pool for mono rasterizer on the stack.
- [raster] Remove 5-level gray AA mode from monochrome rasterizer.
-
- The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
- serve, which is, to adjust the pool size. But the pool is now
- allocated on the stack on demand.
-
- * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [base] Do not reorder library->renderers upon use.
-
- Instead of keeping `library->renderers' in a MRU order, just leave
- it as-is. The MRU machinery wasn't thread-safe.
-
- With this patch, rasterizing glyphs from different faces from
- different threads doesn't fail choosing rasterizer
- (FT_Err_Cannot_Render_Glyph).
-
- Easiest to see that crash was to add a `printf' (or otherwise let
- thread yield in FT_Throw with debugging enabled).
-
- * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
- (FT_Outline_Render): Don't call `FT_Set_Renderer'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [raster] Allocate render pool for mono rasterizer on the stack.
-
- Instead of using the `render_pool' member of `FT_Library' that is
- provided down to the rasterizer, completely ignore that and allocate
- needed objects on the stack instead.
-
- With this patch, rasterizing glyphs from different faces from
- different threads doesn't crash in the monochrome rasterizer.
-
- * src/raster/ftraster.c (black_TRaster): Remove `buffer',
- `buffer_size', and `worker' members.
-
- (ft_black_render): Create `buffer' locally.
- (ft_black_reset): Updated.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [raster] Remove 5-level gray AA mode from monochrome rasterizer.
-
- It was off by default and couldn't be turned on at runtime. And the
- smooth rasterizer superseded it over ten years ago. No point in
- keeping. Comments suggested that it was there for compatibility
- with FreeType 1.
-
- 550 lines down.
-
- * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
- RASTER_GRAY_LINES): Remove macros and all associated code.
-
- (black_TWorker): Remove `gray_min_x' and `gray_max_x'.
- (black_TRaster): Remove `grays' and `gray_width'.

- (ft_raster5_renderer_class): Removed.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [smooth] Allocate render pool for smooth rasterizer on the stack.
-
- Instead of using the `render_pool' member of `FT_Library' that is
- provided down to the rasterizer, completely ignore that and allocate
- needed objects on the stack instead.
-
- With this patch, rasterizing glyphs from different faces from
- different threads doesn't crash in the smooth rasterizer.

-
- [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
-
- Previously the code had stipulation for using a per-TT_Size exec
- context if `size->debug' was true. But there was no way that
- `size->debug' could *ever* be true. As such, the code was always
- using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
- This was, clearly, not threadsafe.
-
- With this patch, loading glyphs from different faces from different
- threads doesn't crash in the bytecode loader code.

- [autofit] Allocate AF_Loader on the stack instead of AF_Module.
-
- Stop sharing a global `AF_Loader'. Allocate one on the stack during

-
- Right now this results in about 25% slowdown, to be fixed in a

- FreeType 2.8
- ============
-
- Homepage: http://www.freetype.org
-
- FreeType is a freely available software library to render fonts.
-
- It is written in C, designed to be small, efficient, highly
- customizable, and portable while capable of producing high-quality
- output (glyph images) of most vector and bitmap font formats.
-
- Please read the docs/CHANGES file, it contains IMPORTANT
- INFORMATION.
-
- Read the files `docs/INSTALL*' for installation instructions; see
- the file `docs/LICENSE.TXT' for the available licenses.
-
- The FreeType 2 API reference is located in `docs/reference'; use the
- file `ft2-toc.html' as the top entry point. Additional
- documentation is available as a separate package from our sites. Go
- to
-
- http://download.savannah.gnu.org/releases/freetype/
-
- and download one of the following files.
-
- freetype-doc-2.8.tar.bz2
- freetype-doc-2.8.tar.gz
- ftdoc28.zip
-
- To view the documentation online, go to
-
- http://www.freetype.org/freetype2/documentation.html
-
-
- Mailing Lists
- =============
-
- The preferred way of communication with the FreeType team is using
- e-mail lists.
-
- general use and discussion: freetype@nongnu.org
- engine internals, porting, etc.: freetype-devel@nongnu.org
- announcements: freetype-announce@nongnu.org
- git repository tracker: freetype-commit@nongnu.org
-
- The lists are moderated; see

-
- Bugs
- ====
-
- Please submit bug reports at
-
- https://savannah.nongnu.org/bugs/?group=freetype
-
- Alternatively, you might report bugs by e-mail to
- `freetype-devel@nongnu.org'. Don't forget to send a detailed
- explanation of the problem -- there is nothing worse than receiving
- a terse message that only says `it doesn't work'.
-
-
- Enjoy!

-The git archive doesn't contain pre-built configuration scripts for
-UNIXish platforms. To generate them say
-
- sh autogen.sh
-
-which in turn depends on the following packages:
-
- automake (1.10.1)
- libtool (2.2.4)
- autoconf (2.62)
-
-The versions given in parentheses are known to work. Newer versions
-should work too, of course. Note that autogen.sh also sets up proper
-file permissions for the `configure' and auxiliary scripts.
-
-The autogen.sh script now checks the version of above three packages
-whether they match the numbers above. Otherwise it will complain and
-suggest either upgrading or using an environment variable to point to
-a more recent version of the required tool(s).
-
-Note that `aclocal' is provided by the `automake' package on Linux,
-and that `libtoolize' is called `glibtoolize' on Darwin (OS X).
-
-
-For static builds which don't use platform specific optimizations, no
-configure script is necessary at all; saying
-
- make setup ansi
- make
-
-should work on all platforms which have GNU make (or makepp).
-
-
-Similarly, a build with `cmake' can be done directly from the git
-repository.

-The makefile.os4 is for the AmigaOS4 SDK. To use it, type
-"make -f makefile.os4", it produces a link library libft2_ppc.a.
-
-The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on
-68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de).
-To use it, type "make assign", then "make"; it produces a link library
-libft2_ppc.a.
-
-The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available,
-latest sold version was 6.50, updates can be found in Aminet). It is
-based on the version found in the sourcecode of ttf.library 0.83b for
-FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com,
-http://ragriffi.home.sprynet.com).
-
-You will also need the latest include files and amiga.lib from the
-Amiga web site (http://www.amiga.com/3.9/download/NDK3.9.lha) for
-AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up.
-
-To use it, call "smake assign" and then "smake" from the builds/amiga
-directory. The results are:
-
-- A link library "ft2_680x0.lib" (where x depends on the setting of
- the CPU entry in the smakefile) containing all FreeType2 parts
- except of the init code, debugging code, and the system interface
- code.
-
-- ftsystem.o, an object module containing the standard version of the
- system interface code which uses fopen() fclose() fread() fseek()
- ftell() malloc() realloc() and free() from lib:sc.lib (not pure).
-
-- ftsystempure.o, an object module containing the pure version of the
- system interface code which uses Open() Close() Read() Seek()
- ExamineFH() AsmAllocPooled() AsmFreePooled() etc. This version can
- be used in both normal programs and in Amiga run-time shared system
- librarys (can be linked with lib:libinit.o, no copying of DATA and
- BSS hunks for each OpenLibrary() necessary). Source code is in
- src/base/ftsystem.c.
-
-- ftdebug.o, an object module containing the standard version of the
- debugging code which uses vprintf() and exit() (not pure).
- Debugging can be turned on in FT:include/freetype/config/ftoption.h
- and with FT_SetTraceLevel().
-
-- ftdebugpure.o, an object module containing the pure version of the
- debugging code which uses KVPrintf() from lib:debug.lib and no
- exit(). For debugging of Amiga run-time shared system libraries.
- Source code is in src/base/ftdebug.c.
-
-- NO ftinit.o. Because linking with a link library should result in
- linking only the needed object modules in it, but standard
- ftsystem.o would force ALL FreeType2 modules to be linked to your
- program, I decided to use a different scheme: You must #include
- FT:src/base/ftinit.c in your sourcecode and specify with #define
- statements which modules you need. See
- include/freetype/config/ftmodule.h.
-
-
-To use in your own programs:
-
-- Insert the #define and #include statements from top of
- include/freetype/config/ftmodule.h in your source code and
- uncomment the #define statements for the FreeType2 modules you need.
-
-- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for
- calling the FreeType2 functions, because the link library and the
- object files are compiled with PARAMETERS=BOTH.
-
-- "smake assign" (assign "FT:" to the FreeType2 main directory).
-
-- Compile your program.
-
-- Link with either ftsystem.o or ftsystempure.o, if debugging enabled
- with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with
- ft2_680x0.lib as link library.
-
-
-To adapt to other compilers:
-
-- The standard ANSI C maximum length of 31 significant characters in
- identifiers is not enough for FreeType2. Check if your compiler has
- a minimum length of 40 significant characters or can be switched to
- it. "idlen=40" is the option for SAS/C. Setting #define
- HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested).
-
-- Make sure that the include directory in builds/amiga is searched
- before the normal FreeType2 include directory, so you are able to
- replace problematic include files with your own version (same may be
- useful for the src directory).
-
-- An example of how to replace/workaround a problematic include file
- is include/freetype/config/ftconfig.h; it changes a #define that
- would prevent SAS/C from generating XDEF's where it should do that and
- then includes the standard FreeType2 include file.
-
-Local Variables:
-coding: latin-1

-Compiling FreeType 2 with PureC compiler
-========================================
-
-[See below for a German version.]
-
-To compile FreeType 2 as a library the following changes must be applied:
-
-- All *.c files must start with an uppercase letter.
- (In case GEMSCRIPT is available:
- Simply drag the whole FreeType 2 directory to the file `FNames.SIC'.)
-
-- You have to change the INCLUDE directory in PureC's compiler options
- to contain both the `INCLUDE' and `freetype2\include' directory.
- Example:
-
- INCLUDE;E:\freetype2\include
-
-- The file `freetype2/include/Ft2build.h' must be patched as follows to
- include ATARI.H:
-
- #ifndef FT2_BUILD_GENERIC_H_
- #define FT2_BUILD_GENERIC_H_
-
- #include "ATARI.H"
-
-
-
-Compilieren von FreeType 2 mit PureC
-====================================
-
-Um FreeType 2 als eine Bibliothek (library) zu compilieren, muss folgendes
-gendert werden:
-
-- Alle *.c-files mssen mit einem GROSSBUCHSTABEN beginnen.
- (Falls GEMSCRIPT zur Verfgung steht:
- Den kompletten Ordner freetype2 auf die Datei `FNames.SIC' draggen.)
-
-- In den Compiler-Optionen von PureC muss das INCLUDE directory auf INCLUDE
- und freetype2\include verweisen. Z.B.:
-
- INCLUDE;E:\freetype2\include
-
-- In der Datei freetype2/include/Ft2build.h muss zu Beginn
- ein #include "ATARI.H" wie folgt eingefgt werden:
-
- #ifndef FT2_BUILD_GENERIC_H_
- #define FT2_BUILD_GENERIC_H_
-
- #include "ATARI.H"

-#
-# This file is derived from the files `Platform/Darwin.cmake' and

-# altered for iOS development.
-
-
-# Options
-# -------
-#
-# IOS_PLATFORM = OS | SIMULATOR
-#
-# This decides whether SDKS are selected from the `iPhoneOS.platform' or
-# `iPhoneSimulator.platform' folders.
-#
-# OS - the default, used to build for iPhone and iPad physical devices,
-# which have an ARM architecture.
-# SIMULATOR - used to build for the Simulator platforms, which have an
-# x86 architecture.
-#
-# CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder
-#
-# By default, this location is automatically chosen based on the
-# IOS_PLATFORM value above. If you manually set this variable, it
-# overrides the default location and forces the use of a particular
-# Developer Platform.
-#
-# CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder
-#
-# By default, this location is automatically chosen based on the
-# CMAKE_IOS_DEVELOPER_ROOT value. In this case it is always the most
-# up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path. If you
-# manually set this variable, it forces the use of a specific SDK
-# version.
-#
-#
-# Macros
-# ------
-#
-# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE)
-#
-# A convenience macro for setting Xcode specific properties on targets.

-This folder contains
-
- * Makefile skeletons for Apple MPW (Macintosh's Programmer's Workshop)
-
- * Python script to generate MPW makefile from skeleton
-
- * Metrowerks CodeWarrior 9.0 project file in XML format
-
-------------------------------------------------------------
-
-1. What is this
----------------
-
-Files in this directory are designed to build FreeType
-running on classic MacOS. To build FreeType running on
-Mac OS X, build as the system is UNIX.
-
-However, Mac OS X is most useful to manipulate files in
-vanilla FreeType to fit classic MacOS.
-
-The information about MacOS specific API is written in
-appendix of this document.
-
-2. Requirement
---------------
-
-You can use MPW: a free-charged developer environment
-by Apple, or CodeWarrior: a commercial developer
-environment by Metrowerks. GCC for MPW and Symantec
-"Think C" are not tested at present.
-
-
- 2-1. Apple MPW
- --------------
-
- Following C compilers are tested:
-
- m68k target: Apple SC 8.9.0d3e1
- ppc target: Apple MrC 5.0.0d3c1
-
- The final MPW-GM (official release on 1999/Dec) is too
- old and cannot compile FreeType, because bundled C
- compilers cannot search header files in sub directories.
- Updating by the final MPW-PR (pre-release on 2001/Feb)
- is required.
-
- Required files are downloadable from:
-
- http://developer.apple.com/tools/mpw-tools/index.html
-
- Also you can find documents how to update by MPW-PR.
-
- Python is required to restore MPW makefiles from the
- skeletons. Python bundled to Mac OS X is enough. For
- classic MacOS, MacPython is available:
-
- http://homepages.cwi.nl/~jack/macpython/
-
- MPW requires all files are typed by resource fork.
- ResEdit bundled to MPW is enough. In Mac OS X,
- /Developer/Tools/SetFile of DevTool is useful to
- manipulate from commandline.
-
- 2-2. Metrowerks CodeWarrior
- ---------------------------
-
- XML project file is generated and tested by
- CodeWarrior 9.0. Older versions are not tested
- at all. At present, static library for ppc target
- is available in the project file.
-
-
-3. How to build
----------------
-
- 3-1. Apple MPW
- --------------
- Detailed building procedure by Apple MPW is
- described in following.
-
- 3-1-1. Generate MPW makefiles from the skeletons
- ------------------------------------------------
-
- Here are 4 skeletons for following targets are
- included.
-
- - FreeType.m68k_far.make.txt
- Ancient 32bit binary executable format for
- m68k MacOS: System 6, with 32bit addressing
- mode (far-pointer-model) So-called "Toolbox"
- API is used.
-
- - FreeType.m68k_cfm.make.txt
- CFM binary executable format for m68k MacOS:
- System 7. So-called "Toolbox" API is used.
-
- - FreeType.ppc_classic.make.txt
- CFM binary executable format for ppc MacOS:
- System 7, MacOS 8, MacOS 9. So-called "Toolbox"
- API is used.
-
- - FreeType.ppc_carbon.make.txt
- CFM binary executable format for ppc MacOS:
- MacOS 9. Carbon API is used.
-
- At present, static library is only supported,
- although targets except of m68k_far are capable
- to use shared library.
-
- MPW makefile syntax uses 8bit characters. To keep
- from violating them during version control, here
- we store skeletons in pure ASCII format. You must
- generate MPW makefile by Python script ascii2mpw.py.
-
- In Mac OS X terminal, you can convert as:
-
- python builds/mac/ascii2mpw.py \
- < builds/mac/FreeType.m68k_far.make.txt \
- > FreeType.m68k_far.make
-
- The skeletons are designed to use in the top
- directory where there are builds, include, src etc.
- You must name the generated MPW makefile by removing
- ".txt" from source skeleton name.
-
- 3-1-2. Add resource forks to related files
- ------------------------------------------
-
- MPW's Make and C compilers cannot recognize files
- without resource fork. You have to add resource
- fork to the files that MPW uses. In Mac OS X
- terminal of the system, you can do as:
-
- find . -name '*.[ch]' -exec \
- /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
-
- find . -name '*.make' -exec \
- /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
-
-
- 3-1-3. Open MPW shell and build
- -------------------------------
-
- Open MPW shell and go to the top directory that
- FreeType sources are extracted (MPW makefile must
- be located in there), from "Set Directory" in
- "Directory" menu.
-
- Choose "Build" from "Build" menu, and type the
- name of project by removing ".make" from MPW
- makefile, as: FreeType.m68k_far
-
- If building is successfully finished, you can find
- built library in objs/ directory.
-
-
- 3-2. Metrowerks CodeWarrior
- ---------------------------
-
- Detailed building procedure by Metrowerks
- CodeWarrior (CW) 9.0 is described in following.
-
- 3-2-1. Import XML project file
- ------------------------------
-
- CW XML project file is not ready for double-
- click. Start CodeWarrior IDE, and choose
- "Import project" in "File" menu. Choose XML
- project file: builds/mac/ftlib.prj.xml.
- In next, you will be asked where to save CW
- native project file: you must choose
- "builds/mac/ftlib.prj". The project file is
- designed with relative path from there. After
- CW native project file is generated, it is
- automatically loaded, small project window
- titled "ftlib.prj" is displayed.
-
- 3-2-2. Building
- ---------------
- Choose "Make" from "Project" menu. If building
- is successfully finished, you can find built
- library at objs/FreeTypeLib.
-
-4. TODO
--------
-
- 4-1. All modules should be included
- -----------------------------------
-
- At present, MPW makefiles and CW project file are
- just updated versions of these by Leonard. Some
- modules are added after the last maintenance, they
- are not included.
-
- 4-2. Working test with ftdemos
- ------------------------------
-
- At present, MPW makefiles and CW project file can
- build FreeType for classic MacOS. But their working
- behaviours are not tested at all. Building ftdemos
- for classic MacOS and working test is required.
-
- 4-3. Porting Jam onto MPW
- -------------------------
-
- FreeType uses Jam (and FT-Jam) for unified cross-
- platform building tool. At present, Jam is not ported
- to MPW. To update classic MacOS support easily,
- building by Jam is expected on MPW.
-
-
-APPENDIX I
-----------
-
- A-1. Framework dependencies
- ---------------------------
-
- src/base/ftmac.c adds two Mac-specific features to
- FreeType. These features are based on MacOS libraries.
-
- * accessing resource-fork font
- The fonts for classic MacOS store their graphical data
- in resource forks which cannot be accessed via ANSI C
- functions. FreeType2 provides functions to handle such
- resource fork fonts, they are based on File Manager
- framework of MacOS. In addition, HFS and HFS+ file
- system driver of Linux is supported. Following
- functions are for this purpose.
-
- FT_New_Face_From_Resource()
- FT_New_Face_From_FSSpec()
- FT_New_Face_From_FSRef()
-
- * resolving font name to font file
- The font menu of MacOS application prefers font name
- written in FOND resource than sfnt resource. FreeType2
- provides functions to find font file by name in MacOS
- application, they are based on QuickDraw Font Manager
- and Apple Type Service framework of MacOS.
-
- FT_GetFile_From_Mac_Name()
- FT_GetFile_From_Mac_ATS_Name()
-
- Working functions for each MacOS are summarized as
- following.
-
- upto MacOS 6:
- not tested (you have to obtain MPW 2.x)
-
- MacOS 7.x, 8.x, 9.x (without CarbonLib):
- FT_GetFile_From_Mac_Name()
- FT_New_Face_From_Resource()
- FT_New_Face_From_FSSpec()
-
- MacOS 9.x (with CarbonLib):
- FT_GetFile_From_Mac_Name()
- FT_New_Face_From_Resource()
- FT_New_Face_From_FSSpec()
- FT_New_Face_From_FSRef()
-
- Mac OS X upto 10.4.x:
- FT_GetFile_From_Mac_Name() deprecated
- FT_New_Face_From_FSSpec() deprecated
- FT_GetFile_From_Mac_ATS_Name() deprecated?
- FT_New_Face_From_FSRef()
-
- A-2. Deprecated Functions
- -------------------------
-
- A-2-1. FileManager
- ------------------
-
- For convenience to write MacOS application, ftmac.c
- provides functions to specify a file by FSSpec and FSRef,
- because the file identification pathname had ever been
- unrecommended method in MacOS programming.
-
- Toward to MacOS X 10.4 & 5, Carbon functions using FSSpec
- datatype is noticed as deprecated, and recommended to
- migrate to FSRef datatype. The big differences of FSRef
- against FSSpec are explained in Apple TechNotes 2078.
-
- http://developer.apple.com/technotes/tn2002/tn2078.html
-
- - filename length: the max length of file
- name of FSRef is 255 chars (it is limit of HFS+),
- that of FSSpec is 31 chars (it is limit of HFS).
-
- - filename encoding: FSSpec is localized by
- legacy encoding for each language system,
- FSRef is Unicode enabled.
-
- A-2-2. FontManager
- ------------------
-
- Following functions receive QuickDraw fontname:
-
- FT_GetFile_From_Mac_Name()
-
- QuickDraw is deprecated and replaced by Quartz
- since Mac OS X 10.4. They are still kept for
- backward compatibility. By undefinition of
- HAVE_QUICKDRAW in building, you can change these
- functions to return FT_Err_Unimplemented always.
-
- Replacement functions are added for migration.
-
- FT_GetFile_From_Mac_ATS_Name()
-
- They are usable on Mac OS X only. On older systems,
- these functions return FT_Err_Unimplemented always.
-
- The detailed incompatibilities and possibility
- of FontManager emulation without QuickDraw is
- explained in
-
- http://www.gyve.org/~mpsuzuki/ats_benchmark.html
-
- A-3. Framework Availabilities
- -----------------------------
-
- The framework of MacOS are often revised, especially
- when new format of binary executable is introduced.
- Following table is the minimum version of frameworks
- to use functions used in FreeType2. The table is
- extracted from MPW header files for assembly language.
-
- *** NOTE ***
- The conditional definition of available data type
- in MPW compiler is insufficient. You can compile
- program using FSRef data type for older systems
- (MacOS 7, 8) that don't know FSRef data type.

- (*)
- In the "Classic": the original binary executable
- format, these framework functions are directly
- transformed to MacOS system call. Therefore, the
- exact availability should be checked by running
- system.
-
- (**)
- InterfaceLib is bundled to MacOS and its version
- is usually equal to MacOS. There's no separate
- update for InterfaceLib. It is supposed that
- there's no InterfaceLib 9.x for m68k platforms.
- In fact, these functions are FSRef dependent.
-
- (***)
- ATSUI framework is available on ATSUnicode 8.5 on
- ppc Toolbox CFM, CarbonLib 1.0 too. But its base:
- ATS font manager is not published in these versions.

- Notes
-
- Mac suitcase files can (and often do!) contain multiple fonts. To
- support this I use the face_index argument of FT_(Open|New)_Face()
- functions, and pretend the suitcase file is a collection.
-
- Warning: fbit and NFNT bitmap resources are not supported yet. In old
- sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
- resources instead of the `bdat' table in the sfnt resource. Therefore,
- face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
- resource is unavailable at present.
-
- The Mac FOND support works roughly like this:
-
- - Check whether the offered stream points to a Mac suitcase file. This
- is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
- stream that gets passed to our init_face() routine is a stdio stream,
- which isn't usable for us, since the FOND resources live in the
- resource fork. So we just grab the stream->pathname field.
-
- - Read the FOND resource into memory, then check whether there is a
- TrueType font and/or(!) a Type 1 font available.
-
- - If there is a Type 1 font available (as a separate `LWFN' file), read
- its data into memory, massage it slightly so it becomes PFB data, wrap
- it into a memory stream, load the Type 1 driver and delegate the rest
- of the work to it by calling FT_Open_Face(). (XXX TODO: after this
- has been done, the kerning data from the FOND resource should be
- appended to the face: On the Mac there are usually no AFM files
- available. However, this is tricky since we need to map Mac char
- codes to ps glyph names to glyph ID's...)
-
- - If there is a TrueType font (an `sfnt' resource), read it into memory,
- wrap it into a memory stream, load the TrueType driver and delegate
- the rest of the work to it, by calling FT_Open_Face().
-
- - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
- itself, even though it doesn't contains `POST' resources. To handle
- this special case without opening the file an extra time, we just
- ignore errors from the `LWFN' and fallback to the `sfnt' if both are
- available.

- FreeType 2 Project Files for VS.NET 2005
- (Pocket PC)
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
-the following targets:
-
-<ul>
- <li>PPC/SP 2003 (Pocket PC 2003)</li>
- <li>PPC/SP WM5 (Windows Mobile 5)</li>
- <li>PPC/SP WM6 (Windows Mobile 6)</li>
-</ul>
-
-It compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

-<h1>
- FreeType 2 Project Files for VS.NET 2008
- (Pocket PC)
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
-the following targets:
-
-<ul>
- <li>PPC/SP 2003 (Pocket PC 2003)</li>
- <li>PPC/SP WM5 (Windows Mobile 5)</li>
- <li>PPC/SP WM6 (Windows Mobile 6)</li>
-</ul>
-
-It compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

- FreeType 2 Project Files for VS.NET 2005
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>. It
-compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

-<h1>
- FreeType 2 Project Files for VS.NET 2008
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>. It
-compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

- FreeType 2 Project Files for VS.NET 2010 or newer
-</h1>
-
-<p>This directory contains a project file for Visual C++ (VS.NET 2010
-or newer), named <tt>freetype.vcxproj</tt>, and Visual Studio, called
-<tt>freetype.sln</tt>. It compiles the following libraries from the
-FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build
- freetype28d.lib - debug build
- freetype28ST.lib - release build; single threaded
- freetype28STd.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MTd.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Both Win32 and x64 builds are supported.</p>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs\vc2010</tt>
-directory.</p>
-
-<p>Customization of the FreeType library is done by editing the
-<tt>ftoption.h</tt> header file in the top-level <tt>devel</tt> path.
-Alternatively, you may copy the file to another directory and change the
-include directory in <tt>freetype.users.props</tt>.</p>
-
-<p>To configure library dependencies like <em>zlib</em> and <em>libpng</em>,
-edit the <tt>freetype.users.props</tt> file in this directory. It also
-simplifies automated (command-line) builds using <a
-href="http://msdn.microsoft.com/library/dd393574%28v=vs.100%29.aspx">msbuild</a>.</p>

-<h1>
- FreeType 2 Project Files for Visual C++ and VS.NET 2005
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt>. It
-compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

- FreeType 2 Project Files for Visual C++ and VS.NET 2005
- (Pocket PC)
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
-the following targets:
-
-<ul>
- <li>PPC/SP 2003 (Pocket PC 2003)</li>
- <li>PPC/SP WM5 (Windows Mobile 5)</li>
- <li>PPC/SP WM6 (Windows Mobile 6)</li>
-</ul>
-
-It compiles the following libraries from the FreeType 2.8 sources:</p>
-
-<ul>
- <pre>
- freetype28.lib - release build; single threaded
- freetype28_D.lib - debug build; single threaded
- freetype28MT.lib - release build; multi-threaded
- freetype28MT_D.lib - debug build; multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings. ZIP
-archives are already stored this way, so no further action is required. If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings. For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option. Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

- /* */
- /* - You can put a copy of this file in your build directory, more */

- /* is the name of a directory that is included _before_ the FreeType */
- /* include path during compilation. */
- /* */
- /* The default FreeType Makefiles and Jamfiles use the build */
- /* directory `builds/<system>' by default, but you can easily change */
- /* that for your own projects. */
- /* */
- /* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
- /* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
- /* locate this file during the build. For example, */
- /* */
- /* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
- /* #include <freetype/config/ftheader.h> */
- /* */
- /* will use `$BUILD/myftoptions.h' instead of this file for macro */
- /* definitions. */
- /* */
- /* Note also that you can similarly pre-define the macro */
- /* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
- /* that are statically linked to the library at compile time. By */
- /* default, this file is <freetype/config/ftmodule.h>. */

-CHANGES BETWEEN 2.7.1 and 2.8
-
- I. IMPORTANT CHANGES
-
- - Support for OpenType Variation Fonts is now complete. The last
- missing part was handling the `VVAR' and `MVAR' tables, which is
- available with this release.
-
- - A new function `FT_Face_Properties' allows the control of some
- module and library properties per font. Currently, the
- following properties can be handled: stem darkening, LCD filter
- weights, and the random seed for the `random' CFF operator.
-
- - The PCF change to show more `colourful' family names (introduced
- in version 2.7.1) was too radical; it can now be configured with
- PCF_CONFIG_OPTION_LONG_FAMILY_NAMES at compile time. If
- activated, it can be switched off at run time with the new pcf
- property `no-long-family-names'. If the `FREETYPE_PROPERTIES'
- environment variable is available, you can say
-
- FREETYPE_PROPERTIES=pcf:no-long-family-names=1
-
- - Support for the following scripts has been added to the
- auto-hinter.
-
- Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
- Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
- Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
- Viet, Tifinagh, Unified Canadian Syllabics, Vai
-
-
- II. IMPORTANT BUG FIXES
-
- - `Light' auto-hinting mode no longer uses TrueType metrics for
- TrueType fonts. This bug was introduced in version 2.4.6,
- causing horizontal scaling also. Almost all GNU/Linux
- distributions (with Fedora as a notable exception) disabled the
- corresponding patch for good reasons; chances are thus high that
- you won't notice a difference.
-
- If optical backward compatibility for legacy applications is
- necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
- configuration option. However, it is strongly recommended to
- avoid that, adjusting font sizes instead.
-
- - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
- now scales the font linearly again (bug introduced in version
- 2.4.6).
-
- - CVE-2017-8105, CVE-2017-8287: Older FreeType versions have
- out-of-bounds writes caused by heap-based buffer overflows
- related to Type 1 fonts.
-
- https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105
- https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287
-
-
- III. MISCELLANEOUS
-
- - A new function `FT_Set_Default_Properties' has been added to
- parse the `FREETYPE_PROPERTIES' environment variable
- (previously, it was internal only). `FT_Init_FreeType' always
- call this function, but `FT_New_Library' does not (similar to
- `FT_Add_Default_Modules').
-
- - To be in sync with OpenType version 1.7 and newer, macros
-
- FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
- FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
- TT_NAME_ID_PREFERRED_FAMILY
- TT_NAME_ID_PREFERRED_SUBFAMILY
-
- are renamed to
-
- FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
- FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
- TT_NAME_ID_TYPOGRAPHIC_FAMILY
- TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY
-
- The old macro names are deprecated (but still available).
-
- - Support for SFNT `name' tables has been improved.
-
- . Format 1 `name' tables are now supported. Use new function
- `FT_Get_Sfnt_LangTag' to access associated language tags.
-
- . Language, encoding, and name IDs have been updated to OpenType
- version 1.8.1.
-
- - The new CFF engine now handles the `random' operator. All CFF
- opcodes are now supported.
-
- - The CFF module has a new property `random-seed' to control the
- pseudo-random number generation for the `random' operator.
-
- - The `freetype-config' script is now a wrapper of `pkg-config' if
- this program is available in the path.
-
- - FT_LOAD_TARGET_LCD is now a variant of FT_LOAD_TARGET_LIGHT;
- this should provide better rendering results.
-
- - A mode to display light auto-hinting with sub-pixel positioning
- has been added to `ftdiff'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.7 and 2.7.1
-
- I. IMPORTANT CHANGES
-
- - Support for the new CFF2 font format as introduced with OpenType
- 1.8 has been contributed by Dave Arnolds from Adobe.
-
- - Preliminary support for variation fonts as specified in OpenType
- 1.8 (in addition to the already existing support for Adobe's MM
- and Apple's GX formats). Dave Arnolds contributed handling of
- advance width change variation; more will come in the next
- version.
-
-
- II. IMPORTANT BUG FIXES
-
- - Handling of raw CID fonts was partially broken (bug introduced
- in 2.6.4).
-
- - CVE-2016-10328: Older FreeType versions had an out-of-bounds
- write caused by a heap-based buffer overflow related to the CFF
- fonts.
-
- http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328
-
-
- III. MISCELLANEOUS
-
- - Some limits for TrueType bytecode execution have been tightened
- to speed up FreeType's handling of malformed fonts, in
- particular to quickly abort endless loops.
-
- - The number of twilight points can no longer be set to an
- arbitrarily large value.
-
- - The total number of jump opcode instructions (like JMPR) with
- negative arguments is dynamically restricted; the same holds
- for the total number of iterations in LOOPCALL opcodes.
-
- The dynamic limits are based on the number of points in a glyph
- and the number of CVT entries. Please report if you encounter a
- font where the selected values are not adequate.
-
- - PCF family names are made more `colourful'; they now include the
- foundry and information whether they contain wide characters.
- For example, you no longer get `Fixed' but rather `Sony Fixed'
- or `Misc Fixed Wide'.
-
- - A new function `FT_Get_Var_Blend_Coordinates' (with its alias
- name `FT_Get_MM_Blend_Coordinates') to retrieve the normalized
- blend coordinates of the currently selected variation instance
- has been added to the Multiple Masters interface.
-
- - A new function `FT_Get_Var_Design_Coordinates' to retrieve the
- design coordinates of the currently selected variation instance
- has been added to the Multiple Masters interface.
-
- - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
- information without loading the (embedded) bitmap itself.
-
- - Retrieving advance widths from bitmap strikes (using
- `FT_Get_Advance' and `FT_Get_Advances') have been sped up.
-
- - The usual round of fuzzer fixes to better reject malformed
- fonts.
-
- - The `ftmulti' demo program can now switch engines with key `H'.
-
- - The `ftstring' demo program can now show some built-in,
- non-latin sample strings (to be selected with the TAB key).
-
- - The `ftview' demo program can now switch between a font's
- charmaps using the TAB key.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6.5 and 2.7
-
- I. IMPORTANT CHANGES
-
- - As announced earlier, the 2.7.x series now uses the new subpixel
- hinting mode as the default, emulating a modern version of
- ClearType.
-
- This change inevitably leads to different rendering results, and
- you might change the `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
- configuration option to adapt it to your taste (or use the new
- `FREETYPE_PROPERTIES' environment variable). See the
- corresponding entry below for version 2.6.4, which gives more
- information.
-
- - A new option `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
- introduced. If set (which is the default), an environment
- variable `FREETYPE_PROPERTIES' can be used to control driver
- properties. Example:
-
- FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
- cff:no-stem-darkening=1 \
- autofitter:warping=1
-
- This allows to select, say, the subpixel hinting mode at runtime
- for a given application. See file `ftoption.h' for more.
-
-
- II. IMPORTANT BUG FIXES
-
- - After loading a named instance of a GX variation font, the
- `face_index' value in the returned `FT_Face' structure now
- correctly holds the named instance index in the upper 16bits as
- documented.
-
-
- III. MISCELLANEOUS
-
- - A new macro `FT_IS_NAMED_INSTANCE' to test whether a given face
- is a named instance.
-
- - More fixes to GX font handling.
-
- - Apple's `GETVARIATION' bytecode operator (needed for GX
- variation font support) has been implemented.
-
- - Another round of fuzzer fixes, mainly to reject invalid fonts
- faster.
-
- - Handling of raw CID fonts was broken (bug introduced in version
- 2.6.4).
-
- - The smooth rasterizer has been streamlined to make it faster by
- approx. 20%.
-
- - The `ftgrid' demo program now understands command line option
- `-d' to give start-up design coordinates.
-
- - The `ftdump' demo program has a new command line option `-p' to
- dump TrueType bytecode instructions.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6.4 and 2.6.5
-
- I. IMPORTANT BUG FIXES
-
- - Compilation works again on Mac OS X (bug introduced in version
- 2.6.4).
-
-
- II. IMPORTANT CHANGES
-
- - The new subpixel hinting mode is now disabled by default; it
- will be enabled by default in the forthcoming 2.7.x series.
- Main reason for reverting this feature is the principle of least
- surprise: a sudden change in appearance of all fonts (even if
- the rendering improves for almost all recent fonts) should not
- be expected in a new micro version of a series.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6.3 and 2.6.4
-
- I. IMPORTANT CHANGES
-
- - A new subpixel hinting mode has been contributed by Nikolaus
- Waxweiler, which is now the default rendering mode for TrueType
- fonts. It implements (almost everything of) version 40 of the
- bytecode engine.
-
- The existing code base in FreeType (the `Infinality code') was
- stripped to the bare minimum and all configurability removed in
- the name of speed and simplicity. The configurability was
- mainly aimed at legacy fonts like Arial, Times New Roman, or
- Courier. [Legacy fonts are fonts that modify vertical stems to
- achieve clean black-and-white bitmaps.] The new mode focuses on
- applying a minimal set of rules to all fonts indiscriminately so
- that modern and web fonts render well while legacy fonts render
- okay.
-
- Activation of the subpixel hinting support can be controlled
- with the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration
- option at compile time: If set to value 1, you get the old
- Infinality mode (which was never the default due to its
- slowness). Value 2 activates the new subpixel hinting mode, and
- value 3 activates both. The default is value 2.
-
- At run time, you can select the subpixel hinting mode with the
- `interpreter-version' property (provided you have compiled in
- the corresponding hinting mode); see `ftttdrv.h' for more.
-
- - Support for the following scripts has been added to the
- auto-hinter.
-
- Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi,
- Malayalam, Sinhala, Tamil
-
-
- II. MISCELLANEOUS
-
- - Type 42 fonts as created by LilyPond are now supported.
-
- - Minor rendering improvements in the auto-hinter.
-
- - For experimental reasons, the old CFF engine now supports all
- CFF operators except `random', including the deprecated Multiple
- Masters instructions. This allows the display of fonts like
- `ITCGaramondMM-It.otf' (without font variations, though).
-
- - Another round of fixes to improve handling of invalid fonts.
-
- - The `ftgrid' demo program now displays the rendered pixels also;
- this can be switched off with the `b' key. Selection of various
- LCD filtering modes can be done with the `L' key.
-
- - The demo programs have been extended to allow selection of all
- available TrueType bytecode engines.
-
- - A very early beta version of a new, Qt based demo program called
- `ftinspect' is part of the source code bundle; it will
- eventually supersede the other demo programs. Currently, you
- have to compile it manually with `qmake; make'; note that many
- features are still missing.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6.2 and 2.6.3
-
- I. IMPORTANT CHANGES
-
- - Khmer, Myanmar, Bengali, and Kannada script support has been
- added to the auto-hinter.
-
-
- II. MISCELLANEOUS
-
- - Better support of Indic scripts like Devanagari by using a
- top-to-bottom hinting flow.
-
- - All FreeType macros starting with two underscores have been
- renamed to avoid a violation of both the C and C++ standards.
- Example: Header macros of the form `__FOO_H__' are now called
- `FOO_H_'. In most cases, this should be completely transparent
- to the user. The exception to this is `__FTERRORS_H__', which
- must be sometimes undefined by the user to get FreeType error
- strings: Both this form and the new `FTERRORS_H_' macro are
- accepted for backward compatibility.
-
- - Minor improvements mainly to the Type 1 driver.
-
- - The new CFF engine now supports all Type 2 operators except
- `random'.
-
- - The macro `_STANDALONE_', used for compiling the B/W and smooth
- rasterizers as stand-alone modules, has been renamed to
- `STANDALONE_', since macro names starting with an underscore and
- followed by an uppercase letter are reserved in both C and C++.
-
- - Function `FT_Library_SetLcdFilterWeights' now also activates
- custom LCD filter weights (instead of just adjusting them).
-
- - Support for `unpatented hinting' has been completely removed:
- Consequently, the two functions `FT_Face_CheckTrueTypePatents'
- and `FT_Face_SetUnpatentedHinting' now return always false,
- doing nothing.
-
- - The `ftgamma' demo program has been modernized; the gamma grid
- display has been moved from `ftview' to this program.
-
- - In `ftview', it is now possible to cycle through the available
- LCD filtering modes.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6.1 and 2.6.2
-
- I. IMPORTANT CHANGES
-
- - The auto-hinter now supports stem darkening, to be controlled by
- the new `no-stem-darkening' and `darkening-parameters'
- properties. This is an experimental feature contributed by
- Nikolaus Waxweiler, and the interface might change in a future
- release.
-
- - By default, stem darkening is now switched off (for both the CFF
- engine and the auto-hinter). The main reason is that you need
- linear alpha blending and gamma correction to get correct
- rendering results, and the latter is not yet available in most
- freely available rendering stacks like X11. Applying stem
- darkening without proper gamma correction leads to far too dark
- rendering results.
-
- - The meaning of `FT_RENDER_MODE_LIGHT' has been slightly
- modified. It now essentially means `no hinting along the
- horizontal axis'; in particular, no change of glyph advance
- widths. Consequently, the auto-hinter is used for all scalable
- font formats except for CFF. It is planned that other
- font-specific rendering engines (TrueType, Type 1) will follow.
-
-
- II. MISCELLANEOUS
-
- - The default LCD filter has been changed to be normalized and
- color-balanced.
-
- - For better compatibility with FontConfig, function
- `FT_Library_SetLcdFilter' accepts a new enumeration value
- `FT_LCD_FILTER_LEGACY1' (which has the same meaning as
- `FT_LCD_FILTER_LEGACY').
-
- - A large number of bugs have been detected by using the libFuzzer
- framework, which should further improve handling of invalid
- fonts. Thanks again to Kostya Serebryany and Bungeman!
-
- - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration
- option, controls the maximum number of executed opcodes within a
- bytecode program. You don't want to change this except for very
- special situations (e.g., making a library fuzzer spend less
- time to handle broken fonts).
-
- - The smooth renderer has been made faster.
-
- - The `ftstring' demo program now supports sub-pixel rendering;
- use key `l' to cycle through the LCD modes.
-
- - The `ftstring' demo program now supports colour rendering; use
- the `space' key to cycle through various colour combinations.
-
- - The graphical demo programs now use a default gamma value of 1.8
- (instead of 1.2).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.6 and 2.6.1
-
- I. IMPORTANT BUG FIXES
-
- - It turned out that for CFFs only the advance widths should be
- taken from the `htmx' table, not the side bearings. This bug,
- introduced in version 2.6.0, makes it necessary to upgrade if
- you are using CFFs; otherwise, you get cropped glyphs with GUI
- interfaces like GTK or Qt.
-
- - Accessing Type 42 fonts returned incorrect results if the glyph
- order of the embedded TrueType font differs from the glyph order
- of the Type 42 charstrings table.
-
-
- II. IMPORTANT CHANGES
-
- - The header file layout has been changed (again), moving all
- header files except `ft2build.h' into a subdirectory tree.
-
- Doing so reduces the possibility of header file name clashes
- (e.g., FTGL's `FTGlyph.h' with FreeType's `ftglyph.h') on case
- insensitive file systems like Mac OS X or Windows.
-
- Applications that use (a) the `freetype-config' script or
- FreeType's `freetype2.pc' file for pkg-config to get the include
- directory for the compiler, and (b) the documented way for
- header inclusion like
-
- #include <ft2build.h>
- #include FT_FREETYPE_H
- ...
-
- don't need any change to the source code.
-
- - Simple access to named instances in GX variation fonts is now
- available (in addition to the previous method via FreeType's MM
- interface). In the `FT_Face' structure, bits 16-30 of the
- `face_index' field hold the current named instance index for the
- given face index, and bits 16-30 of `style_flags' contain the
- number of instances for the given face index. `FT_Open_Face'
- and friends also understand the extended bits of the face index
- parameter.
-
- You need to enable TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new
- feature. Otherwise, bits 16-30 of the two fields are zero (or
- are ignored).
-
- - Lao script support has been added to the auto-hinter.
-
-
- III. MISCELLANEOUS
-
- - The auto-hinter's Arabic script support has been enhanced.
-
- - Superscript-like and subscript-like glyphs as used by various
- phonetic alphabets like the IPA are now better supported by the
- auto-hinter.
-
- - The TrueType bytecode interpreter now runs slightly faster.
-
- - Improved support for builds with cmake.
-
- - The function `FT_CeilFix' now always rounds towards plus
- infinity.
-
- - The function `FT_FloorFix' now always rounds towards minus
- infinity.
-
- - A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it
- makes FreeType ignore pre-computed metrics, as needed by font
- validating or font editing programs. Right now, only the
- TrueType module supports it to ignore data from the `hdmx'
- table.
-
- - Another round of bug fixes to better handle broken fonts, found
- by Kostya Serebryany <kcc@google.com>.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5.5 and 2.6
-
- I. IMPORTANT CHANGES
-
- - Behdad Esfahbod contributed code for improved thread-safety,
- which results in the following model.
-
- * An `FT_Face' object can only be safely used from one thread at
- a time.
-
- * An `FT_Library' object can now be used without modification
- from multiple threads at the same time.
-
- * `FT_Face' creation and destruction with the same `FT_Library'
- object can only be done from one thread at a time.
-
- One can use a single `FT_Library' object across threads as long
- as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'.
- Any calls to `FT_Load_Glyph' and similar API are safe and do not
- need the lock to be held as long as the same `FT_Face' is not
- used from multiple threads at the same time.
-
- - Thai script support has been added to the auto-hinter.
-
- - Arabic script support has been added to the auto-hinter.
-
- - Following OpenType version 1.7, advance widths and side bearing
- values in CFFs (wrapped in an SFNT structure) are now always
- taken from the `hmtx' table.
-
- - Following OpenType version 1.7, the PostScript font name of a
- CFF font (wrapped in an SFNT structure) is now always taken from
- the `name' table. This is also true for OpenType Collections
- (i.e., TTCs using CFFs subfonts instead of TTFs), where it may
- have a significant difference.
-
- - Fonts natively hinted for ClearType are now supported, properly
- handling selector index 3 of the INSTCTRL bytecode instruction.
-
- - Major improvements to the GX TrueType variation font handling.
-
-
- II. MISCELLANEOUS
-
- - A new auto-hinter property `warping' can switch on and off the
- warping code if this experimental feature is compiled in (by
- defining the AF_CONFIG_OPTION_USE_WARPER configuration option;
- by default this option is now enabled but warping is switched
- off).
-
- The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature,
- available since 2006. Warping only works in `light'
- auto-hinting mode. The idea of the code is to slightly scale
- and shift a glyph along the non-hinted dimension (which is
- usually the horizontal axis) so that as much of its segments are
- aligned (more or less) to the grid. To find out a glyph's
- optimal scaling and shifting value, various parameter
- combinations are tried and scored.
-
- See file `ftautoh.h' for more; the demo programs `ftdiff',
- `ftview', and `ftgrid' can toggle warping with key `w'.
-
- - Some fields in the `FTC_ImageTypeRec' structure have been
- changed from signed to unsigned type, which better reflects the
- actual usage. It is also an additional means to protect against
- malformed input.
-
- This change doesn't break the ABI; however, it might cause
- compiler warnings.
-
- - Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init',
- since this name better reflects its function. For backward
- compatibility, the old function name is still available.
-
- - Function `FT_Get_X11_Font_Format' has been renamed to
- `FT_Get_Font_Format', since this name better reflects its
- function. For backward compatibility, the old function name is
- still available.
-
- Additionally, the header file macro for this function has been
- renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is
- retained for backward compatibility).
-
- - Various improvements to the `ftgrid' demo program.
-
- . It can now display GX and MM fonts while interactively
- manipulating the axes (with keys F2, F3, and F4).
-
- . Anti-aliasing rendering modes can now be selected (with keys
- F5 and F6).
-
- . The display of point numbers can be toggled with key `D'.
-
- - Various improvements to the `ftdump' demo program.
-
- . It now displays information on MM and GX variation axes.
-
- . New command line option `-u' makes it output data in utf-8
- encoding.
-
- - The `ftmulti' demo program can now handle up to six MM or GX
- axes.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5.4 and 2.5.5
-
- I. IMPORTANT BUG FIXES
-
- - Handling of uncompressed PCF files works again (bug introduced
- in version 2.5.4).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5.3 and 2.5.4
-
- I. IMPORTANT BUG FIXES
-
- - A variant of vulnerability CVE-2014-2240 was identified
- (cf. http://savannah.nongnu.org/bugs/?43661) and fixed in the
- new CFF driver. All users should upgrade.
-
- - The new auto-hinter code using HarfBuzz crashed for some invalid
- fonts.
-
- - Many fixes to better protect against malformed input.
-
-
- II. IMPORTANT CHANGES
-
- - Full auto-hinter support of the Devanagari script.
-
- - Experimental auto-hinter support of the Telugu script.
-
- - CFF stem darkening behaviour can now be controlled at build time
- using the eight macros
-
- CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4} .
-
- - Some fields in the `FT_Bitmap' structure have been changed from
- signed to unsigned type, which better reflects the actual usage.
- It is also an additional means to protect against malformed
- input.
-
- This change doesn't break the ABI; however, it might cause
- compiler warnings.
-
-
- III. MISCELLANEOUS
-
- - Improvements to the auto-hinter's algorithm to recognize stems
- and local extrema.
-
- - Function `FT_Get_SubGlyph_Info' always returned an error even in
- case of success.
-
- - Version 2.5.1 introduced major bugs in the cjk part of the
- auto-hinter, which are now fixed.
-
- - The `FT_Sfnt_Tag' enumeration values have been changed to
- uppercase, e.g. `FT_SFNT_HEAD'. The lowercase variants are
- deprecated. This is for orthogonality with all other
- enumeration (and enumeration-like) values in FreeType.
-
- - `cmake' now supports builds of FreeType as an OS X framework and
- for iOS.
-
- - Improved project files for vc2010, introducing a property file.
-
- - The documentation generator for the API reference has been
- updated to produce better HTML code (with proper CSS). At the
- same time, the documentation got a better structure.
-
- - The FT_LOAD_BITMAP_CROP flag is obsolete; it is not used by any
- driver.
-
- - The TrueType DELTAP[123] bytecode instructions now work in
- subpixel hinting mode as described in the ClearType whitepaper
- (i.e., for touched points in the non-subpixel direction).
-
- - Many small improvements to the internal arithmetic routines.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5.2 and 2.5.3
-
- I. IMPORTANT BUG FIXES
-
- - A vulnerability (CVE-2014-2240) was identified and fixed in the
- new CFF driver (cf. http://savannah.nongnu.org/bugs/?41697).
- All users should upgrade.
-
- - More bug fixes related to correct positioning of composite
- glyphs.
-
- - Many fixes to better protect against malformed input.
-
-
- II. IMPORTANT CHANGES
-
- - FreeType can now use the HarfBuzz library to greatly improve the
- auto-hinting of fonts that use OpenType features: Many glyphs
- that are part of such features but don't have cmap entries are
- now handled properly, for example small caps or superscripts.
- Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to
- activate HarfBuzz support.
-
- You need HarfBuzz version 0.9.19 or newer.
-
- Note that HarfBuzz depends on FreeType; this currently causes a
- chicken-and-egg problem that can be solved as follows in case
- HarfBuzz is not yet installed on your system.
-
- 1. Compile and install FreeType without the configuration
- macro FT_CONFIG_OPTION_USE_HARFBUZZ.
-
- 2. Compile and install HarfBuzz.
-
- 3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile
- and install FreeType again.
-
- With FreeType's `configure' script the procedure boils down to
- configure, build, and install Freetype, then configure, compile,
- and install HarfBuzz, then configure, compile, and install
- FreeType again (after executing `make distclean').
-
- - All libraries FreeType depends on are now checked using the
- `pkg-config' configuration files first, followed by alternative
- methods.
-
- - The new value `auto' for the various `--with-XXX' library
- options (for example `--with-harfbuzz=auto') makes the
- `configure' script automatically link to the libraries it finds.
- This is now the default.
-
- - In case FreeType's `configure' script can't find a library, you
- can pass environment variables to circumvent pkg-config, and
- those variables have been harmonized as a consequence of the
- changes mentioned above:
-
- LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS
- LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS
- LIBPNG_LDFLAGS -> LIBPNG_LIBS
-
- `./configure --help' shows all available environment variables.
-
- - The `freetype-config' script now understands option `--static'
- to emit static linking information.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5.1 and 2.5.2
-
- I. IMPORTANT BUG FIXES
-
- - Improving the display of some broken TrueType fonts introduced a
- bug that made FreeType crash on some popular (but not fully
- conformant) fonts like `ahronbd.ttf'.
-
- - Another round of improvements to correct positioning and hinting
- of composite glyphs in TrueType fonts.
-
-
- II. MISCELLANEOUS
-
- - Version 2.5.1 introduced a bug in handling embedded bitmap
- strikes of TrueType fonts, causing garbage display under some
- circumstances.
-
- - The `ftgrid' demo program couldn't be compiled in
- non-development builds.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.5 and 2.5.1
-
- I. IMPORTANT BUG FIXES
-
- - For some WinFNT files, the last glyph wasn't displayed but
- incorrectly marked as invalid.
-
- - The vertical size of glyphs was incorrectly set after a call to
- `FT_GlyphSlot_Embolden', resulting in clipped glyphs.
-
- - Many fields of the `PCLT' table in SFNT based fonts (if accessed
- with `FT_Get_Sfnt_Table') were computed incorrectly.
-
- - In TrueType fonts, hinting of composite glyphs could sometimes
- deliver incorrect positions of components or even distorted
- shapes.
-
-
- II. IMPORTANT CHANGES
-
- - WOFF font format support has been added.
-
- - The auto-hinter now supports Hebrew. Greek and Cyrillic support
- has been improved.
-
- - Support for the forthcoming `OS/2' SFNT table version 5, as can
- be found e.g. in the `Sitka' font family for Windows 8.1.
-
- - The header file layout has been changed. After installation,
- all files are now located in `<prefix>/include/freetype2'.
-
- Applications that use (a) `freetype-config' or FreeType's
- `pkg-config' file to get the include directory for the compiler,
- and (b) the documented way for header inclusion like
-
- #include <ft2build.h>
- #include FT_FREETYPE_H
- ...
-
- don't need any change to the source code.
-
-
- III. MISCELLANEOUS
-
- - The stem darkening feature of the new CFF engine can now be
- fine-tuned with the new `darkening-parameters' property.
-
- - `ftgrid' has been updated to toggle various engines with the `H'
- key, similar to `ftview' and `ftdiff'.
-
- - The functionality of `ttdebug' has been greatly enhanced.
-
- . It now displays twilight, storage, and control value data; key
- `T' shows the twilight point table, key `S' the storage data,
- and key `C' the control value table.
-
- . Some keys have been reassigned from lowercase to their
- uppercase equivalents; for example `q' to quit the program is
- now `Q'.
-
- . Key `f' finishes the current function.
-
- . Key `R' restarts the debugger.
-
- . Keys `b' and `p' set a breakpoint.
-
- . Key `B' provides a function call backtrace.
-
- - Better support of ARMv7 and x86_64 processors.
-
- - Apple's `sbix' color bitmap format is now supported.
-
- - Improved auto-hinter rendering for many TrueType fonts,
- especially in the range 20-40ppem.
-
- - A new face flag `FT_FACE_FLAG_COLOR' has been added (to be
- accessed with the macro `FT_HAS_COLOR').
-
- - `FT_Gzip_Uncompress' (modeled after zlib's `uncompress'
- function) has been added; this is a by-product of the newly
- added WOFF support.
-
- - Support for a build with `cmake' has been contributed by John
- Cary <cary@txcorp.com>.
-
- - Support for x64 builds with Visual C++ has been contributed by
- Kenneth Miller <kennethadammiller@yahoo.com>
-
- - Manual pages for most demo programs have been added.
-
- - The GETINFO bytecode instruction for TrueType fonts was buggy if
- used to retrieve subpixel hinting information. It was necessary
- to set selector bit 6 to get results for selector bits 7-10,
- which is wrong.
-
- - Improved computation of emulated vertical metrics for TrueType
- fonts.
-
- - Fixed horizontal start-up position of vertical phantom points in
- TrueType bytecode.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.12 and 2.5
-
- I. IMPORTANT BUG FIXES
-
- - The cache manager function `FTC_Manager_Reset' didn't flush the
- cache.
-
-
- II. IMPORTANT CHANGES
-
- - Behdad Esfahbod (on behalf of Google) contributed support for
- color embedded bitmaps (eg. color emoji).
-
- A new load flag, FT_LOAD_COLOR, makes FreeType load color
- embedded-bitmaps, following this draft specification
-
- https://color-emoji.googlecode.com/git/specification/v1.html
-
- which defines two new SFNT tables, `CBDT' and `CBLC' (named and
- modeled after `EBDT' and `EBLC', respectively). The color
- bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to
- represent BGRA pre-multiplied sRGB images. If PNG support is
- available, PNG color images as defined in the same proposed
- specification are supported also.
-
- Note that color bitmaps are converted to grayscale if client
- didn't ask for color.
-
- - As announced in the previous release, the old FreeType CFF
- engine is now disabled by default. It can be conditionally
- compiled by defining the configuration macro
- CFF_CONFIG_OPTION_OLD_ENGINE.
-
- - As announced in the previous release, all code related to macro
- FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming
- obsolete.
-
-
- III. MISCELLANEOUS
-
- - The property API (`FT_Property_Get' and `FT_Property_Set') is
- now declared as stable.
-
- The exception, however, are the experimental auto-hinter
- properties `glyph-to-script-map' and `fallback-script' which are
- subject to change in a forthcoming release.
-
- - `ftview' has been updated to support color embedded bitmaps; it
- can be toggled on and off with key `c'. The small cache toggle
- is now key `K'.
-
- - It is now possible to control the version of the TrueType
- hinting engine using the new `interpreter-version' property of
- the `truetype' module: Versions 35 and 38 (the default) are
- supported, which roughly corresponds to disable and enable
- subpixel hinting support, respectively.
-
- In both `ftview' and `ftdiff', switching between the two
- versions can be done with key `H'. In the `ftbench' demo
- program, command line option `-H' has been extended to activate
- the non-default interpreter version.
-
- - The `ttdebug' program has been further improved. In particular,
- it accepts a new command line option `-H' to select the hinting
- engine.
-
- - `ftdump's verbose option has been renamed to `-V'. For all demo
- programs, `-v' now shows version information.
-
- - Another round of TrueType subpixel hinting fixes.
-
- - The `apinames' tool can now create an import file for NetWare.
-
- - 64bit compilation of the new CFF engine was buggy.
-
- - Some fixes to improve robustness in memory-tight situations.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.11 and 2.4.12
-
- - We have another CFF parsing and hinting engine! Written by Dave
- Arnold <darnold@adobe.com>, this work has been contributed by
- Adobe in collaboration with Google. It is vastly superior to
- the old CFF engine, and it will replace it in the next release.
- Right now, it is still off by default, and you have to
- explicitly select it using the new `hinting-engine' property of
- the cff driver:
-
- ...
- #include FT_MODULE_H
- #include FT_CFF_DRIVER_H
-
- FT_Library library;
- int engine = FT_CFF_HINTING_ADOBE;
-
-
- ...
- FT_Property_Set( library, "cff", "hinting-engine", &engine );
-
- The code has a (mature) beta status; we encourage all users to
- test it and report any problems.
-
- In case you want to activate the new CFF engine unconditionally,
- apply this patch:
-
---- snip ---
-diff --git a/src/cff/cffobjs.c b/src/cff/cffobjs.c

-
- return FT_Err_Ok;
---- snip ---
-
- - The macro FT_CONFIG_OPTION_OLD_INTERNALS is no longer set by
- default. In the next release, we will completely remove the
- associated code. Please update your programs in case you are
- still using this macro.
-
-
- II. MISCELLANEOUS
-
- - The (top-level) `configure' script now respects the MAKE
- environment variable to specify a `make' binary. For backward
- compatibility, GNUMAKE still overrides MAKE, though.
-
- - The `ftview' and `ftdiff' demo programs have been redesigned,
- showing more options permanently on the screen, among other
- minor improvements.
-
- - Using the `H' key, it is now possible to select the CFF engine
- in both `ftview' and `ftdiff'.
-
- - The new command line option `-H' for `ftbench' selects the Adobe
- CFF engine.
-
- - It is now possible to directly select the LCD rendering mode
- with the keys `A'-`F' in `ftview'. The key mapping for cycling
- through LCD modes has been changed from `K' and `L' to `k' and
- `l', and toggling custom LCD filtering is no longer mapped to
- key `F' but to key `L'.
-
- - In `ftdiff', key `x' toggles between layout modes: Either use
- the advance width (this is new and now the default) or the
- bounding box information to determine line breaks.
-
- - For all demo tools, the new command line option `-v' shows the
- version.
-
- - For the demo tools with a GUI, the new command line options `-w'
- and `-h' select the width and the height of the output window,
- respectively.
-
- - The `ttdebug' program was broken and has been reactivated. Note
- that this program is not compiled by default.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.10 and 2.4.11
-
- I. IMPORTANT BUG FIXES
-
- - Some vulnerabilities in the BDF implementation have been fixed.
- Users of this font format should upgrade.
-
-
- II. IMPORTANT CHANGES
-
- - Subpixel hinting support has been contributed by Infinality,
- based on Greg Hitchcock's whitepaper at
-
- http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
-
- Originally, it was a separate patch available from
-
- http://www.infinality.net/blog/
-
- and which has been integrated.
-
- Note that ClearType support is not completely implemented! In
- particular, full support for the options `compatible_widths',
- `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
- instruction) is missing.
-
- Activation of subpixel hinting support can be controlled with
- the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it
- is switched off by default. This feature is still experimental;
- we welcome test reports!
-
- - Support for OpenType collections (OTC) has been added.
-
- - Pure CFF fonts within an SFNT wrapper are now supported.
-
-
- III. MISCELLANEOUS
-
- - Minor rendering improvements to the auto-hinter.
-
- - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°.
-
- - Experimental support to handle `property modules', for example
- to control the behaviour of the auto-hinter. The API consists
- of two new functions, `FT_Property_Set' and `FT_Property_Get'.
-
- The code is still subject to change and should not be used for
- production.
-
- - The `ftdiff' demo program now supports UTF-8 encoded input files
- for option `-f'.
-
- - Using keys `r' and `R', you can now adjust the stroker radius in
- the `ftview' demo program.
-
- - Other, minor fixes and improvements.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.9 and 2.4.10
-
- I. IMPORTANT BUG FIXES
-
- - Incremental glyph loading as needed by ghostscript was broken.
-
-
- II. MISCELLANEOUS
-
- - A new function `FT_Outline_EmboldenXY', contributed by Alexei
- Podtelezhnikov.
-
- - In the `ftview' demo program, key `e' has been replaced with `x'
- and `y' to embolden in the horizontal and vertical direction,
- respectively.
-
- - The glyph spacing computation in `FT_GlyphSlot_Embolden' (and
- similar code in `ftview') has been improved.
-
- - Minor improvements to the TrueType bytecode interpreter and
- glyph loader, the auto-hinter, and the B/W rasterizer.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.8 and 2.4.9
-
- I. IMPORTANT BUG FIXES
-
- - Another round of fixes to better handle invalid fonts. Many of
- them are vulnerabilities (see CVE-2012-1126 up to CVE-2012-1144
- and SA48320) so all users should upgrade.
-
-
- II. MISCELLANEOUS
-
- - The `ENCODING -1 <n>' format of BDF fonts is now supported.
-
- - For BDF fonts, support for the whole Unicode encoding range has
- been added.
-
- - Better TTF support for x_ppem != y_ppem.
-
- - `FT_Get_Advances' sometimes returned bogus values.
-
- - The demo programs no longer recognize and handle default
- suffixes; you now have to always specify the complete font name.
-
- - Better rendering and LCD mode cycling added to `ftview'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.7 and 2.4.8
-
- I. IMPORTANT BUG FIXES
-
- - Some vulnerabilities in handling CID-keyed PostScript fonts have
- been fixed; see CVE-2011-3439.
-
-
- II. MISCELLANEOUS
-
- - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value', to
- retrieve most of the dictionary keys in Type 1 fonts.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.6 and 2.4.7
-
- I. IMPORTANT BUG FIXES
-
- - Some vulnerabilities in handling Type 1 fonts have been fixed;
- see CVE-2011-3256.
-
-
- II. MISCELLANEOUS
-
- - FreeType now properly handles ZapfDingbats glyph names while
- constructing a Unicode character map (for fonts which don't have
- one).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.5 and 2.4.6
-
- I. IMPORTANT BUG FIXES
-
- - For TrueType based fonts, the ascender and descender values were
- incorrect sometimes (off by a pixel if the ppem value was not a
- multiple of 5). Depending on the use you might now experience
- a different layout; the change should result in better, more
- consistent line spacing.
-
- - Fix CVE-2011-0226 which causes a vulnerability while handling
- Type 1 fonts.
-
- - BDF fonts containing glyphs with negative values for ENCODING
- were incorrectly rejected. This bug has been introduced in
- FreeType version 2.2.0.
-
- - David Bevan contributed a major revision of the FreeType stroker
- code:
-
- . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
-
- . A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has
- been introduced to support PostScript and PDF miter joins.
-
- . FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
- alias for FT_STROKER_LINEJOIN_MITER.
-
- . Various stroking glitches has been fixed.
-
-
- II. MISCELLANEOUS
-
- - SFNT bitmap fonts which contain an outline glyph for `.notdef'
- only no longer set the FT_FACE_FLAG_SCALABLE flag.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.4 and 2.4.5
-
- I. IMPORTANT BUG FIXES
-
- - A rendering regression for second-order Bézier curves has been
- fixed, introduced in 2.4.3.
-
-
- II. IMPORTANT CHANGES
-
- - If autohinting is not explicitly disabled, FreeType now uses
- the autohinter if a TrueType based font doesn't contain native
- hints.
-
- - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made
- redundant and is simply ignored; this means that FreeType now
- ignores the global advance width value in TrueType fonts.
-
-
- III. MISCELLANEOUS
-
- - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of
- a font.
-
- - Support for PCF files compressed with bzip2 has been contributed
- by Joel Klinghed. To make this work, the OS must provide a
- bzip2 library.
-
- - Bradley Grainger contributed project and solution files in
- Visual Studio 2010 format.
-
- - Again some fixes to better handle broken fonts.
-
- - Some improvements to the B/W rasterizer.
-
- - Fixes to the cache module to improve robustness.
-
- - Just Fill Bugs contributed (experimental) code to compute blue
- zones for CJK Ideographs, improving the alignment of horizontal
- stems at the top or bottom edges.
-
- - The `ftgrid' demo program can now display autohinter segments,
- to be toggled on and off with key `s'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.3 and 2.4.4
-
- I. IMPORTANT BUG FIXES
-
- - UVS support (TrueType/OpenType cmap format 14) support is fixed.
- This regression has been introduced in version 2.4.0.
-
-
- II. MISCELLANEOUS
-
- - Detect tricky fonts (e.g. MingLiU) by the lengths and checksums
- of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when
- a TrueType font without family name is given. The previous fix,
- introduced in 2.4.3, was too rigorous, causing many subsetted
- fonts (mainly from PDF files) displayed badly because FreeType
- forced rendering with the TrueType bytecode engine instead of
- the autohinter.
-
- - Better support for 64bit platforms.
-
- - More fixes to improve handling of broken fonts.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.2 and 2.4.3
-
- I. IMPORTANT BUG FIXES
-
- - Fix rendering of certain cubic, S-shaped arcs. This regression
- has been introduced in version 2.4.0.
-
-
- II. MISCELLANEOUS
-
- - To fix the above mentioned rendering issue, a new spline
- flattening algorithm has been introduced which speeds up both
- conic and cubic arcs.
-
- - Handling of broken fonts has been further improved.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.1 and 2.4.2
-
- I. IMPORTANT BUG FIXES
-
- - A stack overflow in CFF Type2 CharStrings interpreter is fixed.
-
- - Handling Type 42 font deallocation was broken; additionally, the
- library is now more robust against malformed Type 42 fonts.
-
-
- II. MISCELLANEOUS
-
- - Two new functions, `FT_Reference_Library' (in FT_MODULE_H) and
- `FT_Reference_Face' (in FT_FREETYPE_H), have been added to
- simplify life-cycle management. A counter gets initialized to 1
- at the time an FT_Library (or FT_Face) structure is created.
- The two new functions increment the respective counter.
- `FT_Done_Library' and `FT_Done_Face' then only destroy a library
- or face if the counter is 1, otherwise they simply decrement the
- counter.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.4.0 and 2.4.1
-
- I. IMPORTANT CHANGES
-
- - A serious bug in the CFF font module prevented display of many
- glyphs in CFF fonts like `MinionPro-Regular.otf'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.12 and 2.4.0
-
- I. IMPORTANT CHANGES
-
- - Since May 2010, all patents regarding the TrueType bytecode
- interpreter have expired worldwide. Consequently, we now define
- TT_CONFIG_OPTION_BYTECODE_INTERPRETER by default (and undefine
- TT_CONFIG_OPTION_UNPATENTED_HINTING).
-
- - A new function `FT_Library_SetLcdFilterWeights' is available to
- adjust the filter weights set by `FT_Library_SetLcdFilter'.
-
-
- II. MISCELLANEOUS
-
- - Thanks to many reports from Robert Święcki, FreeType's stability
- in handling broken or damaged fonts is much improved.
-
- - Support for LCD filter control has been added to the demo
- programs `ftdiff' and `ftview'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.11 and 2.3.12
-
- I. IMPORTANT CHANGES
-
- - For `FT_Open_Face', new parameters are available to ignore
- preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and
- FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY.
-
-
- II. MISCELLANEOUS
-
- - Support for incremental font loading (controlled with the
- FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default.
-
- - Better support for vertical metrics.
-
- - Various minor bug fixes.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.10 and 2.3.11
-
- I. IMPORTANT BUG FIXES
-
- - Version 2.3.10 broke PCF support.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.10 and 2.3.9
-
- I. IMPORTANT BUG FIXES
-
- - If all ASCII digits in a font have the same (unscaled) width,
- the autohinter respects this and won't change it.
-
- - TrueType fonts are now rasterized correctly if the horizontal
- and vertical resolution differ.
-
- - Type 1 fonts are now handled with increased precision internally
- to avoid serious rounding issues if non-integral coordinates are
- encountered.
-
- - Horizontally condensed CFF fonts (using the font matrix) were
- rendered incorrectly. This bug has been introduced after
- release 2.3.5.
-
-
- II. IMPORTANT CHANGES
-
- - Support for the SFNT cmap 13 table format (as defined by the new
- OpenType 1.6 specification) has been added.
-
- - B/W rasterization of well-hinted TrueType fonts at small sizes
- has been greatly improved.
-
- - Calculation of vertical metrics in OpenType fonts has been
- improved.
-
-
- III. MISCELLANEOUS
-
- - It is now possible to change the emboldening factor in the
- `ftview' demo program with keys `e' and `E'.
-
- - It is now possible to change the slant value in the `ftview'
- demo program with keys `s' and `S'.
-
- - The 5-levels grayscale mode of the `ftraster' module (which
- FreeType doesn't use by default) was broken since version 2.3.0.
-
- - Compilation of the `ftgrays' and `ftraster' modules was broken
- in stand-alone mode.
-
- - Various fixes for compilation on 64bit and 16bit architectures.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.9 and 2.3.8
-
- I. IMPORTANT BUG FIXES
-
- - Very unfortunately, FreeType 2.3.8 contained a change that broke
- its official ABI. The end result is that programs compiled
- against previous versions of the library, but dynamically linked
- to 2.3.8 can experience memory corruption if they call the
- `FT_Get_PS_Font_Info' function.
-
- We recommend all users to upgrade to 2.3.9 as soon as possible,
- or to downgrade to a previous release of the library if this is
- not an option.
-
- The origin of the bug is that a new field was added to the
- publicly defined `PS_FontInfoRec' structure. Unfortunately,
- objects of this type can be stack or heap allocated by callers
- of `FT_Get_PS_Font_Info', resulting in a memory buffer
- overwrite with its implementation in 2.3.8.
-
- If you want to know whether your code is vulnerable to this
- issue, simply search for the substrings `PS_FontInfo' and
- `PS_Font_Info' in your source code. If none is found, your code
- is safe and is not affected.
-
- The FreeType team apologizes for the problem.
-
- - The POSIX support of MacOS resource-fork fonts (Suitcase fonts
- and LaserWriter Type1 PostScript fonts) was broken in 2.3.8. If
- FreeType2 is built without Carbon framework, these fonts are not
- handled correctly. Version 2.3.7 didn't have this bug.
-
- - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for
- almost all font formats except TrueType fonts.
-
- - Fix a bug in the SFNT kerning table loader/parser which could
- crash the engine if certain malformed tables were encountered.
-
- - Composite SFNT bitmaps are now handled correctly.
-
-
- II. IMPORTANT CHANGES
-
- - The new functions `FT_Get_CID_Is_Internally_CID_keyed' and
- `FT_Get_CID_From_Glyph_Index' can be used to access CID-keyed
- CFF fonts via CID values. This code has been contributed by
- Michael Toftdal.
-
-
- III. MISCELLANEOUS
-
- - `FT_Outline_Get_InsideBorder' returns FT_STROKER_BORDER_RIGHT
- for empty outlines. This was incorrectly documented.
-
- - The `ftview' demo program now supports UTF-8 encoded strings.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.8 and 2.3.7
-
- I. IMPORTANT BUG FIXES
-
- - CID-keyed fonts in an SFNT wrapper were not handled correctly.
-
- - The smooth renderer produced truncated images (on the right) for
- outline parts with negative horizontal values. Most fonts don't
- contain outlines left to the y coordinate axis, but the effect
- was very noticeable for outlines processed with FT_Glyph_Stroke,
- using thick strokes.
-
- - `FT_Get_TrueType_Engine_Type' returned a wrong value if both
- configuration macros TT_CONFIG_OPTION_BYTECODE_INTERPRETER and
- TT_CONFIG_OPTION_UNPATENTED_HINTING were defined.
-
- - The `face_index' field in the `FT_Face' structure wasn't
- initialized properly after calling FT_Open_Face and friends with
- a positive face index for CFFs, WinFNTs, and, most importantly,
- for TrueType Collections (TTCs).
-
-
- II. IMPORTANT CHANGES
-
- - Rudimentary support for Type 1 fonts and CID-keyed Type 1 fonts
- in an SFNT wrapper has been added -- such fonts are used on the
- Mac. The core SFNT tables `TYP1' and `CID ' are passed to the
- PS Type 1 and CID-keyed PS font drivers; other tables (`ALMX',
- `BBOX', etc.) are not supported yet.
-
- - A new interface to extract advance values of glyphs without
- loading their outlines has been added. The functions are called
- `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file
- `ftadvanc.h' (to be accessed as FT_ADVANCES_H).
-
- - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been
- contributed by David Bevan to access the embedding and
- subsetting restriction information of fonts.
-
-
- III. MISCELLANEOUS
-
- - FT_MulFix is now an inlined function; by default, assembler code
- is provided for x86 and ARM. See FT_CONFIG_OPTION_INLINE_MULFIX
- and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more.
-
- - The handling of `tricky' fonts (this is, fonts which don't work
- with the autohinter, needing the font format's hinting engine)
- has been generalized and changed slightly:
-
- . A new face flag FT_FACE_FLAG_TRICKY indicates that the font
- format's hinting engine is necessary for correct rendering.
- The macro FT_IS_TRICKY can be used to check this flag.
-
- . FT_LOAD_NO_HINTING is now ignored for tricky fonts. To really
- force raw loading of such fonts (without hinting), both
- FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used --
- this is something which you probably never want to do.
-
- . Tricky TrueType fonts always use the bytecode interpreter,
- either the patented or unpatented version.
-
- - The function `FT_GlyphSlot_Own_Bitmap' has been moved from
- FT_SYNTHESIS_H to FT_BITMAP_H; it is now part of the `official'
- API. (The functions in FT_SYNTHESIS_H are still subject to
- change, however.)
-
- - In the `ftdiff' demo program you can now toggle the use of
- FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.7 and 2.3.6
-
- I. IMPORTANT BUG FIXES
-
- - If the library was compiled on an i386 platform using gcc, and
- compiler option -O3 was given, `FT_MulFix' sometimes returned
- incorrect results which could have caused problems with
- `FT_Request_Metrics' and `FT_Select_Metrics', returning an
- incorrect descender size.
-
- - Pure CFFs without subfonts were scaled incorrectly if the font
- matrix was non-standard. This bug has been introduced in
- version 2.3.6.
-
- - The `style_name' field in the `FT_FaceRec' structure often
- contained a wrong value for Type 1 fonts. This misbehaviour
- has been introduced in version 2.3.6 while trying to fix
- another problem. [Note, however, that this value is
- informative only since the used algorithm to extract it is
- very simplistic.]
-
-
- II. IMPORTANT CHANGES
-
- - Two new macros, FT_OUTLINE_SMART_DROPOUTS and
- FT_OUTLINE_EXCLUDE_STUBS, have been introduced. Together with
- FT_OUTLINE_IGNORE_DROPOUTS (which was ignored previously) it is
- now possible to control the dropout mode of the `raster' module
- (for B&W rasterization), using the `flags' field in the
- `FT_Outline' structure.
-
- - The TrueType bytecode interpreter now passes the dropout mode to
- the B&W rasterizer. This greatly increases the output for small
- ppem values of many fonts like `pala.ttf'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.6 and 2.3.5
-
- I. IMPORTANT BUG FIXES
-
- - A bunch of potential security problems have been found. All
- users should update.
-
- - Microsoft Unicode cmaps in TrueType fonts are now always
- preferred over Apple cmaps. This is not a bug per se, but there
- exist some buggy fonts created for MS which have broken Apple
- cmaps. This affects only the automatic selection of FreeType;
- it's always possible to manually select an Apple Unicode cmap if
- desired.
-
- - Many bug fixes to the TrueType bytecode interpreter.
-
- - Improved Mac support.
-
- - Subsetted CID-keyed CFFs are now supported correctly.
-
- - CID-keyed CFFs with subfonts which are scaled in a non-standard
- way are now handled correctly.
-
- - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if
- the font was a Windows (bitmap) FNT/FON.
-
-
- II. IMPORTANT CHANGES
-
- - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives
- access to those fields in a CID-keyed font. The code has been
- contributed by Derek Clegg.
-
- - George Williams contributed code to validate the new `MATH'
- OpenType table (within the `otvalid' module). The `ftvalid'
- demo program has been extended accordingly.
-
- - An API for cmap 14 support (for Unicode Variant Selectors, UVS)
- has been contributed by George Williams.
-
- - A new face flag FT_FACE_FLAG_CID_KEYED has been added, together
- with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is
- CID-keyed.
-
-
- III. MISCELLANEOUS
-
- - Build support for symbian has been contributed.
-
- - Better WGL4 glyph name support, contributed by Sergey Tolstov.
-
- - Debugging output of the various FT_TRACEX macros is now sent to
- stderr.
-
- - The `ftview' demo program now provides artificial slanting too.
-
- - The `ftvalid' demo program has a new option `-f' to select the
- font index.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.5 and 2.3.4
-
- I. IMPORTANT BUG FIXES
-
- - Some subglyphs in TrueType fonts were handled incorrectly due to
- a missing graphics state reinitialization.
-
- - Large .Z files (as distributed with some X11 packages) weren't
- handled correctly, making FreeType increase the heap stack in an
- endless loop.
-
- - A large number of bugs have been fixed to avoid crashes and
- endless loops with invalid fonts.
-
-
- II. IMPORTANT CHANGES
-
- - The two new cache functions `FTC_ImageCache_LookupScaler' and
- `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of
- glyphs using an `FTC_Scaler' object; this makes it possible to
- use fractional pixel sizes in the cache. The demo programs have
- been updated accordingly to use this feature.
-
- - A new API `FT_Get_CMap_Format' has been added to get the cmap
- format of a TrueType font. This is useful in handling PDF
- files. The code has been contributed by Derek Clegg.
-
- - The auto-hinter now produces better output by default for
- non-Latin scripts like Indic. This was done by using the CJK
- hinting module as the default instead of the Latin one. Thanks
- to Rahul Bhalerao for this suggestion.
-
- - A new API `FT_Face_CheckTrueTypePatents' has been added to find
- out whether a given TrueType font uses patented bytecode
- instructions. The `ft2demos' bundle contains a new program
- called `ftpatchk' which demonstrates its usage.
-
- - A new API `FT_Face_SetUnpatentedHinting' has been added to
- enable or disable the unpatented hinter.
-
- - Support for Windows FON files in PE format has been contributed
- by Dmitry Timoshkov.
-
-
- III. MISCELLANEOUS
-
- - Vincent Richomme contributed Visual C++ project files for Pocket
- PCs.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.4 and 2.3.3
-
- I. IMPORTANT BUG FIXES
-
- - A serious bug in the handling of bitmap fonts (and bitmap
- strikes of outline fonts) has been introduced in 2.3.3.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.3 and 2.3.2
-
- I. IMPORTANT BUG FIXES
-
- - Remove a serious regression in the TrueType bytecode interpreter
- that was introduced in version 2.3.2. Note that this does not
- disable the improvements introduced to the interpreter in
- version 2.3.2, only some ill cases that occurred with certain
- fonts (though a few popular ones).
-
- - The auto-hinter now ignores single-point contours for computing
- blue zones. This bug created `wavy' baselines when rendering
- text with various fonts that use these contours to model
- mark-attach points (these are points that are never rasterized
- and are placed outside of the glyph's real outline).
-
- - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to
- zero for mono-spaced fonts. Otherwise code that uses them would
- essentially ruin the fixed-advance property.
-
- - Fix CVE-2007-1351 which can cause an integer overflow while
- parsing BDF fonts, leading to a potentially exploitable heap
- overflow condition.
-
-
- II. MISCELLANEOUS
-
- - Fixed compilation issues on some 64-bit platforms (see ChangeLog
- for details).
-
- - A new demo program `ftdiff' has been added to compare TrueType
- hinting, FreeType's auto hinting, and rendering without hinting
- in three columns.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.2 and 2.3.1
-
- I. IMPORTANT BUG FIXES
-
- - FreeType returned incorrect kerning information from TrueType
- fonts when the bytecode interpreter was enabled. This happened
- due to a typo introduced in version 2.3.0.
-
- - Negative kerning values from PFM files are now reported
- correctly (they were read as 16-bit unsigned values from the
- file).
-
- - Fixed a small memory leak when `FT_Init_FreeType' failed for
- some reason.
-
- - The Postscript hinter placed and sized very thin and ghost stems
- incorrectly.
-
- - The TrueType bytecode interpreter has been fixed to get rid of
- most of the rare differences seen in comparison to the Windows
- font loader.
-
-
- II. IMPORTANT CHANGES
-
- - The auto-hinter now better deals with serifs and corner cases
- (e.g., glyph '9' in Arial at 9pt, 96dpi). It also improves
- spacing adjustments and doesn't change widths for non-spacing
- glyphs.
-
- - Many Mac-specific functions are deprecated (but still
- available); modern replacements have been provided for them.
- See the documentation in file `ftmac.h'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.1 and 2.3.0
-
- I. IMPORTANT BUG FIXES
-
- - The TrueType interpreter sometimes returned incorrect horizontal
- metrics due to a bug in the handling of the SHZ instruction.
-
- - A typo in a security check introduced after version 2.2.1
- prevented FreeType to render some glyphs in CFF fonts.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.3.0 and 2.2.1
-
- I. IMPORTANT BUG FIXES
-
- - The PCF font loader is now much more robust while loading
- malformed font files.
-
- - Various memory leaks have been found and fixed.
-
- - The TrueType name loader now deals properly with some fonts that
- encode their names in UTF-16 (the specification was vague, and
- the code incorrectly assumed UCS-4).
-
- - Fixed the TrueType bytecode loader to deal properly with subtle
- monochrome/gray issues when scaling the CVT. Some fonts
- exhibited bad rendering artifacts otherwise.
-
- - `FT_GlyphSlot_Embolden' now supports vertical layouts correctly
- (it mangled the vertical advance height).
-
- - Fixed byte endian issues of `ftmac.c' to support Mac OS X on
- i386.
-
- - The PFR font loader no longer erroneously tags font files
- without any outlines as FT_FACE_FLAG_SCALABLE.
-
-
- II. NEW API FUNCTIONS
-
- - `FT_Library_SetLcdFilter' allows you to select a special filter
- to be applied to the bitmaps generated by `FT_Render_Glyph' if
- one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has
- been selected. This filter is used to reduce color fringes;
- several settings are available through the FT_LCD_FILTER_XXX
- enumeration.
-
- Its declaration and documentation can be found in file
- `include/freetype/ftlcdfil.h' (to be accessed with macro
- FT_LCD_FILTER_H).
-
- *IMPORTANT*: This function returns an error
- (FT_Err_Unimplemented_Feature) in default builds of the library
- for patent reasons. See below.
-
- - `FT_Get_Gasp' allows you to query the flags of the TrueType
- `gasp' table for a given character pixel size. This is useful
- to duplicate the text rendering of MS Windows when the native
- bytecode interpreter is enabled (which isn't the default for
- other patent reasons).
-
- Its declaration and documentation can be found in file
- `include/freetype/ftgasp.h' (to be accessed with macro
- FT_GASP_H).
-
-
- III. IMPORTANT CHANGES
-
- - The auto-hinter has been tuned a lot to improve its results with
- serif fonts, resulting in much better font rendering of many web
- pages.
-
- - The unpatented hinter is now part of the default build of the
- library; we have added code to automatically support `tricky'
- fonts that need it.
-
- This means that FreeType should `just work' with certain Asian
- fonts, like MingLiU, which cannot properly be loaded without a
- bytecode interpreter, but which fortunately do not use any of
- the patented bytecode opcodes. We detect these fonts by name,
- so please report any font file that doesn't seem to work with
- FreeType, and we shall do what we can to support it in a next
- release.
-
- Note that the API hasn't changed, so you can still force
- unpatented hinting with a special parameter to `FT_Open_Face' as
- well. This might be useful in same cases; for example, a PDF
- reader might present a user option to activate it to deal with
- certain `tricky' embedded fonts which cannot be clearly
- identified.
-
- If you are a developer for embedded systems, you might want to
- *disable* the feature to save code space by undefining
- TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'.
-
- - LCD-optimized rendering is now *disabled* in all default builds
- of the library, mainly due to patent issues. For more
- information see:
-
- http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html
-
- A new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING
- has been introduced in `ftoption.h'; manually define it in this
- file if you want to re-enable the feature.
-
- The change only affects the implementation, not the FreeType
- API. This means that clients don't need to be modified, because
- the library still generates LCD decimated bitmaps, but with the
- added constraint that R=G=B on each triplet.
-
- The displayed result should be equal to normal anti-aliased
- rendering.
-
- Additionally, if FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not
- defined, the new `FT_Library_SetLcdFilter' function returns the
- FT_Err_Unimplemented_Feature error code.
-
- - Some computation bugs in the TrueType bytecode interpreter were
- found, which allow us to get rid of very subtle and rare
- differences we had experienced with the Windows renderer.
-
- - It is now possible to cross-compile the library easily. See the
- file `docs/INSTALL.CROSS' for details.
-
- - The file `src/base/ftmac.c' now contains code for Mac OS X only;
- its deprecated function `FT_GetFile_From_Mac_Font_Name' always
- returns an error even if the QuickDraw framework is available.
- The previous version has been moved to `builds/mac/ftmac.c'.
-
- Selecting configure option `--with-quickdraw-carbon' makes the
- build process use the original `ftmac.c' file instead of the Mac
- OS X-only version.
-
-
- IV. MISCELLANEOUS
-
- - Various performance and memory footprint optimizations have been
- performed on the TrueType and CFF font loaders, sometimes with
- very drastic benefits (e.g., the TrueType loader is now about
- 25% faster; FreeType should use less heap memory under nearly
- all conditions).
-
- - The anti-aliased rasterizer has been optimized and is now 15% to
- 25% percent faster than in previous versions, depending on
- content.
-
- - The Type 1 loader has been improved; as an example, it now skips
- top-level dictionaries properly.
-
- - Better support for Mac fonts on POSIX systems, plus compilation
- fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built.
-
- - Configuration without `--with-old-mac-fonts' does not include
- `ftmac.c' (this was the behaviour in FreeType version 2.1.10).
-
- - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs
- in the kern table.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.2.1 and 2.2
-
- I. IMPORTANT BUG FIXES
-
- - Various integer overflows have been fixed.
-
- - PFB fonts with MacOS resource fork weren't handled correctly on
- non-MacOS platforms.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.2 and 2.1.10
-
-(not released officially)
-
- I. IMPORTANT BUG FIXES
-
- - Vertical metrics for SFNT fonts were incorrect sometimes.
-
- - The FT_HAS_KERNING macro always returned 0.
-
- - CFF OpenType fonts didn't return correct vertical metrics for
- glyphs with outlines.
-
- - If FreeType was compiled without hinters, all font formats based
- on PS outlines weren't scaled correctly.
-
-
- II. IMPORTANT CHANGES
-
- - Version 2.2 no longer exposes its internals, this is, the header
- files located in the `include/freetype/internal' directory of
- the source package are not copied anymore by the `make install'
- command. Consequently, a number of rogue clients which directly
- access FreeType's internal functions and structures won't
- compile without modification.
-
- We provide patches for most of those rogue clients. See the
- following page for more information:
-
- http://www.freetype.org/freetype2/patches/rogue-patches.html
-
- Note that, as a convenience to our Unix desktop users, version
- 2.2 is *binary* compatible with FreeType 2.1.7, which means that
- installing this release on an existing distribution shall not
- break any working desktop.
-
- - FreeType's build mechanism has been redesigned. With GNU make
- it is now sufficient in most cases to edit two files:
- `modules.cfg', to select the library components, and the
- configuration file `include/freetype/config/ftoption.h' (which
- can be copied to the objects directory). Removing unused module
- directories to prevent its compilation and editing
- `include/freetype/config/ftmodule.h' is no longer necessary.
-
- - The LIGHT hinting algorithm produces more pleasant results.
- Also, using the FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph
- always forces auto-hinting, as a special exception. This allows
- you to experiment with it even if you have enabled the TrueType
- bytecode interpreter in your build.
-
- - The auto hinter now employs a new algorithm for CJK fonts, based
- on Akito Hirai's patch. Note that this only works for fonts
- with a Unicode charmap at the moment.
-
- - The following callback function types have changed slightly (by
- adding the `const' keyword where appropriate):
-
- FT_Outline_MoveToFunc
- FT_Outline_LineToFunc
- FT_Outline_ConicToFunc
- FT_Outline_CubicToFunc
- FT_SpanFunc
- FT_Raster_RenderFunc
-
- FT_Glyph_TransformFunc
- FT_Renderer_RenderFunc
- FT_Renderer_TransformFunc
-
- Note that this doesn't affect binary backward compatibility.
-
- - On MacOS, new APIs have been added as replacements for legacy
- APIs: `FT_New_Face_From_FSRef' for `FT_New_Face_From_FSSpec',
- and `FT_GetFile_From_Mac_ATS_Name' for
- `FT_GetFile_From_Mac_Name'. Legacy APIs are still available, if
- FreeType is built without disabling them.
-
- - A new API `FT_Select_Size' has been added to select a bitmap
- strike by its index. Code using other functions to select
- bitmap strikes should be updated to use this function.
-
- - A new API `FT_Get_SubGlyph_Info' has been added to retrieve
- subglyph data. This can be used by rogue clients which used to
- access the internal headers to get the corresponding data.
-
- - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for
- BDF/PCF fonts, and only for them. This causes inconsistency.
- In this release, we undo the change. The intent of the change
- in 2.1.10 is to allow size selection through real dimensions,
- which can now be done through `FT_Request_Size'.
-
- - Some security issues were discovered and fixed in the CFF and
- Type 1 loader, causing crashes of FreeType by malformed font
- files.
-
-
- III. MISCELLANEOUS
-
- - The documentation for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX
- values now better reflects its usage and differences: One set is
- used to specify the hinting algorithm, the other to specify the
- pixel rendering mode.
-
- - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been
- changed to count supported scalable faces (sfnt, LWFN) only, and
- to return the number of available faces via face->num_faces.
- Unsupported bitmap faces (fbit, NFNT) are ignored.
-
- - builds/unix/configure has been improved for MacOS X. It now
- automatically checks available functions in Carbon library, and
- prepare to use newest functions by default. Options to specify
- the dependencies of each Carbon APIs (FSSpec, FSRef, old/new
- QuickDraw, ATS) are available too. By manual disabling of all
- QuickDraw functionality, FreeType can be built without
- `deprecated function' warnings on MacOS 10.4.x, but
- FT_GetFile_Mac_Name in ftmac.c then is changed to a dummy
- function, and returns an `unimplemented' error. For details see
- builds/mac/README.
-
- - SFNT cmap handling has been improved, mainly to run much faster
- with CJK fonts.
-
- - A new function `FT_Get_TrueType_Engine_Type (declared in
- `FT_MODULE_H') is provided to determine the status of the
- TrueType bytecode interpreter compiled into the library
- (patented, unpatented, unimplemented).
-
- - Vertical metrics of glyphs are synthesized if the font does not
- provide such information. You can tell whether the metrics are
- synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of
- the face.
-
- - The demo programs `ftview' and `ftstring' have been rewritten
- for better readability. `ftview' has a new switch `-p' to test
- FT_New_Memory_Face (instead of FT_New_Face).
-
- - FreeType now honours bit 1 in the `head' table of TrueType fonts
- (meaning `left sidebearing point at x=0'). This helps with some
- buggy fonts.
-
- - Rudimentary support for Adobe's new `SING Glyphlet' format. See
-
- http://www.adobe.com/products/indesign/sing_gaiji.html
-
- for more information.
-
- - The `ftdump' program from the `ft2demos' bundle now shows some
- information about charmaps. It also supports a new switch `-v'
- to increase verbosity.
-
- - Better AFM support. This includes track kerning support.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.10 and 2.1.9
-
- I. IMPORTANT BUG FIXES
-
- - The size comparison for BDF and PCF files could fail sometimes.
-
- - Some CFF files were still not loaded correctly. Patch from
- Derek Noonburg.
-
- - The stroker still had some serious bugs.
-
- - Boris Letocha fixed a bug in the TrueType interpreter: The
- NPUSHW instruction wasn't skipped correctly in IF clauses. Some
- fonts like `Helvetica 75 Bold' failed.
-
- - Another serious bug in handling TrueType hints caused many
- distortions. It has been introduced in version 2.1.8, and it is
- highly recommended to upgrade.
-
- - FreeType didn't properly parse empty Type 1 glyphs.
-
- - An unbound dynamic buffer growth was fixed in the PFR loader.
-
- - Several bugs have been fixed in the cache sub-system.
-
- - FreeType behaved incorrectly when resizing two distinct but very
- close character pixel sizes through `FT_Set_Char_Size' (Savannah
- bug #12263).
-
- - The auto-hinter didn't work properly for fonts without a Unicode
- charmap -- it even refused to load the glyphs.
-
-
- II. IMPORTANT CHANGES
-
- - Many fixes have been applied to drastically reduce the amount of
- heap memory used by FreeType, especially when using
- memory-mapped font files (which is the default on Unix systems
- which support them).
-
- - The auto-hinter has been replaced with a new module, called the
- `auto-fitter'. It consumes less memory than its predecessor,
- and it is prepared to support non-latin scripts better in next
- releases.
-
- - George Williams contributed code to read kerning data from PFM
- files.
-
- - FreeType now uses the TT_NAME_ID_PREFERRED_FAMILY and
- TT_NAME_ID_PREFERRED_SUBFAMILY strings (if available) for
- setting family and style in SFNT fonts (patch from Kornfeld
- Eliyahu Peter).
-
- - A new API `FT_Sfnt_Table_Info' (in FT_TRUETYPE_TABLES_H) has
- been added to retrieve name and size information of SFNT tables.
-
- - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has
- been added to validate OpenType tables (BASE, GDEF, GPOS, GSUB,
- JSTF). After validation it is no longer necessary to check
- for errors in those tables while accessing them.
-
- Note that this module might be moved to another library in the
- future to avoid a tight dependency between FreeType and the
- OpenType specification.
-
- - A new API in FT_BITMAP_H (`FT_Bitmap_New', `FT_Bitmap_Convert',
- `FT_Bitmap_Copy', `FT_Bitmap_Embolden', `FT_Bitmap_Done') has
- been added. Its use is to convert an FT_Bitmap structure in
- 1bpp, 2bpp, 4bpp, or 8bpp format into another 8bpp FT_Bitmap,
- probably using a different pitch, and to further manipulate it.
-
- - A new API `FT_Outline_Embolden' (in FT_OUTLINE_H) gives finer
- control how outlines are emboldened.
-
- - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H) now handles bitmaps
- also (code contributed by Chia I Wu). Note that this function
- is still experimental and may be replaced with a better API.
-
- - The method how BDF and PCF bitmap fonts are accessed has been
- refined. Formerly, FT_Set_Pixel_Sizes and FT_Set_Char_Size
- were synonyms in FreeType's BDF and PCF interface. This has
- changed now. FT_Set_Pixel_Sizes should be used to select the
- actual font dimensions (the `strike', which is the sum of the
- `FONT_ASCENT' and `FONT_DESCENT' properties), while
- FT_Set_Char_Size selects the `nominal' size (the `PIXELSIZE'
- property). In both functions, the width parameter is ignored.
-
-
- III. MISCELLANEOUS
-
- - The BDF driver no longer converts all returned bitmaps with a
- depth of 2bpp or 4bpp to a depth of 8bpp. The documentation has
- not mentioned this explicitly, but implementors might have
- relied on this after looking into the source files.
-
- - A new option `--ftversion' has been added to freetype-config to
- return the FreeType version.
-
- - The memory debugger has been updated to dump allocation
- statistics on all allocation sources in the library. This is
- useful to spot greedy allocations when loading and processing
- fonts.
-
- - We removed a huge array of constant pointers to constant strings
- in the `psnames' module. The problem was that compilations in
- PIC mode (i.e., when generating a Unix shared object/dll) put
- the array into the non-shared writable section of the library
- since absolute pointers are not relocatable by nature.
-
- This reduces the memory consumption by approximately 16KByte per
- process linked to FreeType. We now also store the array in a
- compressed form (as a trie) which saves about 20KByte of code as
- well.
-
- - Kirill Smelkov provided patches to make src/raster/ftraster.c
- compile stand-alone again.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.9 and 2.1.8
-
- I. IMPORTANT BUG FIXES
-
- - The function `FT_Get_CharMap_Index' was only declared, without
- any real code. For consistency, it has been renamed to
- `FT_Get_Charmap_Index'. (This function is needed to implement
- cmap caches.)
-
- - `FT_Outline_Get_BBox' sometimes returned incorrect values for
- conic outlines (e.g., for TrueType fonts).
-
- - Handling of `bhed' table has been fixed.
-
- - The TrueType driver with enabled byte code interpreter sometimes
- returned artifacts due to incorrect rounding. This bug has been
- introduced after version 2.1.4.
-
- - The BDF driver dropped the last glyph in the font.
-
- - The BDF driver now uses the DEFAULT_CHAR property (if available)
- to select a glyph shape for the undefined glyph.
-
- - The stroker failed for closed outlines and single points.
-
-
- II. IMPORTANT CHANGES
-
- - George Williams contributed code to handle Apple's font
- distortion technology found in GX fonts (`avar', `cvar', `fvar',
- and `gvar' tables; the Multiple Masters API has been slightly
- extended to cope with the new functionality).
-
- - The `FT_GlyphSlotRec' structure has been extended: The elements
- `lsb_delta' and `rsb_delta' give the difference between hinted
- and unhinted left and right side bearings if autohinting is
- active. Using those values can improve the inter-letter spacing
- considerably. See the documentation of `FT_GlyphSlotRec' and
- the `ftstring' demo program how to use it.
-
- - Loading TrueType and Type 1 fonts has been made much faster.
-
- - The stroker is no longer experimental (but the cache subsystem
- still is).
-
-
- III. MISCELLANEOUS
-
- - A new documentation file `formats.txt' describes various font
- formats supported (and not supported) by FreeType.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.8 and 2.1.7
-
- I. IMPORTANT BUG FIXES
-
- - The native TrueType hinter contained some bugs which prevented
- some fonts to be rendered correctly, most notably Legendum.otf.
-
- - The PostScript hinter now produces improved results.
-
- - The linear advance width and height values were incorrectly
- rounded, making them virtually unusable if not loaded with
- FT_LOAD_LINEAR_DESIGN.
-
- - Indexing CID-keyed CFF fonts is now working: The glyph index is
- correctly treated as a CID, similar to FreeType's CID driver
- module. Note that CID CMap support is still missing.
-
- - The FT_FACE_FLAG_GLYPH_NAMES flag is now set correctly for all
- font formats.
-
- - Some subsetted Type 1 fonts weren't parsed correctly. This bug
- has been introduced in 2.1.7. In summary, the Type 1 parser has
- become more robust.
-
- - Non-decimal numbers weren't parsed correctly in PS fonts.
-
- - The WinFNT driver now correctly reports FT_ENCODING_NONE for all
- but one encoding. Use the new FT_WinFNT_ID_XXX values together
- with `FT_Get_WinFNT_Header' to get the WinFNT charset ID.
-
- - The descender metrics (face->size->metrics.descender) for WinFNT
- bitmap fonts had the wrong sign.
-
- - The (emulated) `seac' support for CFF fonts was broken.
-
- - The `flex' operator didn't work for CFF fonts.
-
- - PS glyphs which use the `hintmask' operator haven't been
- rendered correctly in some cases.
-
- - Metrics for BDF and PCF bitmap font formats have been fixed.
-
- - Autohinting is now disabled for glyphs which are vertically
- distorted or mirrored (using a transformation matrix). This
- fixes a bug which produced zero-height glyphs.
-
- - The `freetype-config' script now handles --prefix and
- --exec-prefix correctly; it also returns the proper --rpath (or
- -R) value if FreeType has been built as a shared library.
-
-
- II. IMPORTANT CHANGES
-
- - Both PCF and BDF drivers now handle the SETWIDTH_NAME and
- ADD_STYLE_NAME properties. Values are appended to
- face->style_name; example: `Bold SemiCondensed'.
-
- - The PCF driver now handles bitmap fonts compressed with the LZW
- algorithm (extension .pcf.Z, compressed with `compress').
-
- - A new API function `FT_Get_CMap_Language_ID' (declared in
- `tttables.h') is available to get the language ID of a
- TrueType/SFNT cmap.
-
- - The hexadecimal format of data after the `StartData' command in
- CID-keyed Type 1 fonts is now supported. While this can't occur
- in file-based fonts, it can happen in document-embedded
- resources of PostScript documents.
-
- - Embedded bitmaps in SFNT-based CFF fonts are now supported.
-
- - A simple API is now available to control FreeType's tracing
- mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file
- `ftdebug.h' for more details.
-
- - YAMATO Masatake contributed improved handling of MacOS resource
- forks on non-MacOS platforms (for example, Linux can mount MacOS
- file systems).
-
- - Support for MacOS has been improved; there is now a new function
- `FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that
- it accepts an FSSpec instead of a path.
-
- - The cache sub-system has been rewritten.
-
- - There is now support for deinstallation of faces.
-
- - A new API function `FTC_Manager_RemoveFaceID' has been added
- to delete all `idle' nodes that correspond to a given
- FTC_FaceID. All `locked' nodes (i.e., those with a reference
- count > 0), will be modified to prevent them from appearing in
- further lookups (they will be cleaned normally when their
- reference count reaches 0).
-
- - There is now support for point scaling (i.e., providing
- character sizes in points + dpis, instead of pixels).
-
- - Three abstract cache classes are now available:
-
- FTC_GCache: Used to store one glyph item per cache node,
- with the ability to group common attributes into
- `families'. This replaces the old
- FTC_GlyphCache class.
-
- FTC_ICache: Used to store one FT_Glyph per cache node. This
- extends FTC_GCache. Family definition, family
- comparison, and glyph loading are however left
- to sub-classes.
-
- FTC_SCache: Used to store up to 16 small bitmaps per cache
- node. This extends FTC_GCache. Family
- definition, family comparison and glyph loading
- are however left to sub-classes.
-
- - The file `src/cache/ftcbasic.c' implements:
-
- FTC_ImageCache: Extends FTC_ICache; implements family
- definitions and glyph loading similar to the
- old API.
-
- FTC_SBitCache: Extends FTC_SCache, implements family
- definitions and glyph loading similar to the
- old API
-
- Client applications should be able to extend FTC_GCache,
- FTC_ICache, or FTC_SCache much more easily (i.e., less code to
- write, and less callbacks). For example, one could envision
- caches that are capable of storing transformed (obliqued),
- stroked, emboldened, or colored glyph images. Use
- `ftcbasic.c' as an example.
-
- - All public APIs are now in `include/freetype/ftcache.h', (to
- be accessed as `FT_CACHE_H'). The contents of
- `include/freetype/cache/' is only needed by applications that
- wish to implement their own caches.
-
- - There were some major performance improvements through the use
- of various programming tricks. Cache hits are up to 70%
- faster than in the old code.
-
- - The FTC_CMapCache has been simplified. Charmaps can only be
- accessed by index right now. There is also a new API named
- `FT_Charmap_GetIndex' for this purpose.
-
- - The demo programs have been updated to the new code. The
- previous versions will not work with the current one.
-
- - Using an invalid face index in FT_Open_Face and friends now
- causes an error even if the font contains a single face only.
-
-
- III. MISCELLANEOUS
-
- - Wolfgang Domröse contributed support files for building FreeType
- on the Atari using the PureC compiler. Note that the Atari is a
- 16bit platform.
-
- - Vitaliy Pasternak contributed project files for VS.NET 2003.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.7 and 2.1.6
-
- I. IMPORTANT BUG FIXES
-
- - Updated to newest libtool version, fixing build problems on
- various platforms.
-
- - On Unix platforms, `make install' didn't copy the correct
- `ftconfig.h' file.
-
- Note that version 2.1.7 contains the same library C source code as
- version 2.1.6.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.6 and 2.1.5
-
- I. IMPORTANT BUG FIXES
-
- - The PFR font driver didn't load kerning tables correctly, and
- the functions in FT_PFR_H didn't work at all.
-
- - Type 1 font files in binary format (PFB) with an end-of-file
- indicator weren't accepted by the FreeType engine.
-
- - Fonts which contain /PaintType and /StrokeWidth no longer cause
- a segfault. This bug has been introduced in version 2.1.5.
-
- - Fonts loaded with FT_LOAD_RENDER no longer cause strange
- results. This bug has been introduced in version 2.1.5.
-
- - Some Windows (bitmap) FNT/FON files couldn't be handled
- correctly.
-
-
- II. IMPORTANT CHANGES
-
- - The internal module API has been heavily changed in favor of
- massive simplifications within the font engine. This also means
- that authors of third-party modules must adapt their code to the
- new scheme.
-
- NOTE: THE NEW SCHEME IS NOT COMPLETED YET. PLEASE WAIT UNTIL A
- FINAL ANNOUNCEMENT!
-
- - The PostScript parser has been enhanced to handle comments and
- strings correctly. Additionally, more syntax forms are
- recognized.
-
- - Added the optional unpatented hinting system for TrueType. It
- allows typefaces which need hinting to produce correct glyph
- forms (e.g., Chinese typefaces from Dynalab) to work acceptably
- without infringing Apple patents. This system is compiled only
- if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
- ftoption.h (activated by default).
-
-
- III. MISCELLANEOUS
-
- - There is now a guard in the public header files to protect
- against inclusion of freetype.h from FreeType 1.
-
- - Direct inclusion of freetype.h and other public header files no
- longer works. You have to use the documented scheme
-
- #include <ft2build.h>
- #include FT_FREETYPE_H
-
- to load freetype.h with a symbolic name. This protects against
- renaming of public header files (which shouldn't happen but
- actually has, avoiding two public header files with the same
- name).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.5 and 2.1.4
-
- I. IMPORTANT BUG FIXES
-
- - Parsing the /CIDFontName field now removes the leading slash to
- be in sync with other font drivers.
-
- - gzip support was buggy. Some fonts could not be read.
-
- - Fonts which have nested subglyphs more than one level deep no
- longer cause a segfault.
-
- - Creation of synthetic cmaps for fonts in CFF format was broken
- partially.
-
- - Numeric font dictionary entries for synthetic fonts are no
- longer overwritten.
-
- - The font matrix wasn't applied to the advance width for Type1,
- CID, and CFF fonts. This caused problems when loading certain
- synthetic Type 1 fonts like `Helvetica Narrow'.
-
- - The test for the charset registry in BDF and PCF fonts is now
- case-insensitive.
-
- - FT_Vector_Rotate sometimes returned strange values due to
- rounding errors.
-
- - The PCF driver now returns the correct number of glyphs
- (including an artificial `notdef' glyph at index 0).
-
- - FreeType now supports buggy CMaps which are contained in many
- CJK fonts from Dynalab.
-
- - Opening an invalid font on a Mac caused a segfault due to
- double-freeing memory.
-
- - BDF fonts with more than 32768 glyphs weren't supported
- properly.
-
-
- II. IMPORTANT CHANGES
-
- - Accessing bitmap font formats has been synchronized. To do that
- the FT_Bitmap_Size structure has been extended to contain new
- fields `size', `x_ppem', and `y_ppem'.
-
- - The FNT driver now returns multiple faces, not multiple strikes.
-
- - The `psnames' module has been updated to the Adobe Glyph List
- version 2.0.
-
- - The `psnames' module now understands `uXXXX[X[X]]' glyph names.
-
- - The algorithm for guessing the font style has been improved.
-
- - For fonts in SFNT format, root->height is no longer increased if
- the line gap is zero. There exist fonts (containing e.g. form
- drawing characters) which intentionally have a zero line gap
- value.
-
- - ft_glyph_bbox_xxx flags are now deprecated in favour of
- FT_GLYPH_BBOX_XXX.
-
- - ft_module_xxx flags are now deprecated in favour of
- FT_MODULE_XXX.
-
- - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} are now
- deprecated in favour of
- FT_ENCODING_{SJIS,GB2312,BIG5,WANSUNG,JOHAB} -- those encodings
- are not specific to Microsoft.
-
-
- III. MISCELLANEOUS
-
- - The autohinter has been further improved; for example, `m'
- glyphs now retain its vertical symmetry.
-
- - Partial support of Mac fonts on non-Mac platforms.
-
- - `make refdoc' (after first `make') builds the HTML
- documentation. You need Python for this.
-
- - The make build system should now work more reliably on DOS-like
- platforms.
-
- - Support for EMX gcc and Watson C/C++ compilers on MS-DOS has
- been added.
-
- - Better VMS build support.
-
- - Support for the pkg-config package by providing a `freetype.pc'
- file.
-
- - New configure option --with-old-mac-fonts for Darwin.
-
- - Some source files have been renamed (mainly to fit into the 8.3
- naming scheme).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.4 and 2.1.3
-
- I. IMPORTANT BUG FIXES
-
- - Updated to newest libtool version, fixing build problems on
- various platforms.
-
- - A fix in the Gzip stream reader: It couldn't read certain .gz
- files properly due to a small typo. In certain cases, FreeType
- could also loop endlessly when trying to load tiny gzipped
- files.
-
- - The configure script now tries to use the system-wide zlib when
- it finds one (instead of the copy found in src/gzip). And
- `freetype-config' has been updated to return relevant flags in
- this case when invoked with `--libs' (e.g. `-lzlib').
-
- - Certain fonts couldn't be loaded by 2.1.3 because they lacked a
- Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously
- rejected them.
-
- - The CFF loader was modified to accept fonts which only contain a
- subset of their reference charset. This prevented the correct
- use of PDF-embedded fonts.
-
- - The logic to detect Unicode charmaps has been modified. This is
- required to support fonts which include both 16-bit and 32-bit
- charmaps (like very recent asian ones) using the new 10 and 12
- SFNT formats.
-
- - The TrueType loader now limits the depth of composite glyphs.
- This is necessary to prevent broken fonts to break the engine by
- blowing the stack with recursive glyph definitions.
-
- - The CMap cache is now capable of managing UCS-4 character codes
- that are mapped through extended charmaps in recent
- TrueType/OpenType fonts.
-
- - The cache sub-system now properly manages out-of-memory
- conditions instead of blindly reporting them to the caller.
- This means that it will try to empty the cache before restarting
- its allocations to see if that can help.
-
- - The PFR driver didn't return the list of available embedded
- bitmaps properly.
-
- - There was a nasty memory leak when using embedded bitmaps in
- certain font formats.
-
-
- II. IMPORTANT CHANGES
-
- - David Chester contributed some enhancements to the auto-hinter
- that significantly increase the quality of its output. The
- Postscript hinter was also improved in several ways.
-
- - The FT_RENDER_MODE_LIGHT render mode was implemented.
-
- - A new API function called `FT_Get_BDF_Property' has been added
- to FT_BDF_H to retrieve BDF properties from BDF _and_ PCF font
- files. THIS IS STILL EXPERIMENTAL, since it hasn't been
- properly tested yet.
-
- - A Windows FNT specific API has been added, mostly to access font
- headers. This is used by Wine.
-
- - TrueType tables without an `hmtx' table are now tolerated when
- an incremental interface is used. This happens for certain
- Type42 fonts passed from Ghostscript to FreeType.
-
- - The PFR font driver is now capable of returning the font family
- and style names when they are available (instead of the sole
- `FontID'). This is performed by parsing an *undocumented*
- portion of the font file!
-
-
- III. MISCELLANEOUS
-
- - The path stroker in FT_STROKER_H has entered beta stage. It now
- works very well, but its interface might change a bit in the
- future. More on this in later releases.
-
- - The documentation for FT_Size_Metrics didn't appear properly in
- the API reference.
-
- - The file docs/VERSION.DLL has been updated to explain versioning
- with FreeType (i.e., comparing release/libtool/so numbers, and
- how to use them in autoconf scripts).
-
- - The installation documentation has been seriously revamped.
- Everything is now in the `docs' directory.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.3 and 2.1.2
-
- I. IMPORTANT BUG FIXES
-
- - FT_Vector_Transform had been incorrectly modified in 2.1.2,
- resulting in incorrect transformations being applied (for
- example, rotations were processed in opposite angles).
-
- - The format 8 and 12 TrueType charmap enumeration routines have
- been fixed (FT_Get_Next_Char returned invalid values).
-
- - The PFR font driver returned incorrect advance widths if the
- outline and metrics resolution defined in the font file were
- different.
-
- - FT_Glyph_To_Bitmap now returns successfully when called with an
- FT_BitmapGlyph argument (it previously returned an error).
-
- - A bug in the Type 1 loader that prevented valid font bounding
- boxes to be loaded from multiple master fonts.
-
- - The SFNT validation code has been rewritten. FreeType can now
- load `broken' fonts that were usable on Windows, but not with
- previous versions of the library.
-
- - The computation of bearings in the BDF driver has been fixed.
-
- - The Postscript hinter crashed when trying to hint certain glyphs
- (more precisely, when trying to apply hints to an empty glyph
- outline).
-
- - The TrueType glyph loader now supports composites in `Apple
- format' (they differ slightly from Microsoft/OpenType ones in
- the way transformation offsets are computed).
-
- - FreeType was very slow at opening certain asian CID/CFF fonts,
- due to fixed increment in dynamic array re-allocations. This
- has been changed to exponential behaviour to get acceptable
- performance.
-
-
-
- II. IMPORTANT CHANGES
-
- - The PCF driver now supports gzip-compressed font files natively.
- This means that you will be able to use all these bitmap fonts
- that come with XFree86 with FreeType (and libXft/libXft2, by
- extension).
-
- - The automatic and postscript hinters have both been updated.
- This results in a relatively important increase of rendering
- quality since many nasty defaults have been suppressed. Please
- visit the web page:
-
- http://www.freetype.org/hinting/smooth-hinting.html
-
- for additional details on this topic.
-
- - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32
- (instead of just being an FT_Int). This breaks source and
- binary compatibility for 16bit systems only, while retaining
- both of them for 32 and 64 bit ones.
-
- Some new flags have been added consequently:
-
- FT_LOAD_NO_AUTOHINT :: Disable the use of the auto-hinter
- (but not native format hinters).
-
- FT_LOAD_TARGET_NORMAL :: Hint and render for normal
- anti-aliased displays.
-
- FT_LOAD_TARGET_MONO :: Hint and render for 1-bit displays.
-
- FT_LOAD_TARGET_LCD :: Hint and render for horizontal RGB or
- BGR sub-pixel displays (like LCD
- screens). THIS IS STILL
- EXPERIMENTAL!
-
- FT_LOAD_TARGET_LCD_V :: Same as FT_LOAD_TARGET_LCD, for
- vertical sub-pixel displays (like
- rotated LCD screens). THIS IS STILL
- EXPERIMENTAL!
-
- FT_LOAD_MONOCHROME is still supported, but only affects
- rendering, not the hinting.
-
- Note that the `ftview' demo program available in the `ft2demos'
- package has been updated to support LCD-optimized display on
- non-paletted displays (under Win32 and X11).
-
- - The PFR driver now supports embedded bitmaps (all formats
- supported), and returns correct kerning metrics for all glyphs.
-
- - The TrueType charmap loader now supports certain `broken' fonts
- that load under Windows without problems.
-
- - The cache API has been slightly modified (it's still a beta!):
-
- - The type FTC_ImageDesc has been removed; it is now replaced
- by FTC_ImageTypeRec. Note that one of its fields is a
- `load_flag' parameter for FT_Load_Glyph.
-
- - The field `num_grays' of FT_SBitRec has been changed to
- `max_grays' in order to fit within a single byte. Its
- maximum value is thus 255 (instead of 256 as previously).
-
-
- III. MISCELLANEOUS
-
- - Added support for the DESTDIR variable during `make install'.
- This simplifies packaging of FreeType.
-
- - Included modified copies of the ZLib sources in `src/gzip' in
- order to support gzip-compressed PCF fonts. We do not use the
- system-provided zlib for now, though this is a probable
- enhancement for future releases.
-
- - The DocMaker tool used to generate the on-line API reference has
- been completely rewritten. It is now located in
- `src/tools/docmaker/docmaker.py'. Features:
-
- - better cross-referenced output
- - more polished output
- - uses Python regular expressions (though it didn't speed the
- program)
- - much more modular structure, which allows for different
- `backends' in order to generate HTML, XML, or whatever
- format.
-
- One can regenerate the API reference by calling:
-
- python src/tools/docmaker/docmaker.py \
- --prefix=ft2 \
- --title=FreeType-2.1.3 \
- --output=<outputdirectory>
- include/freetype/*.h \
- include/freetype/config/*.h \
- include/freetype/cache/*.h
-
- - A new, experimental, support for incremental font loading (i.e.,
- loading of fonts where the glyphs are not in the font file
- itself, but provided by an external component, like a Postscript
- interpreter) has been added by Graham Asher. This is still work
- in progress, however.
-
- - A new, EXPERIMENTAL, path stroker has been added. It doesn't
- suffer from severe rounding errors and treat bezier arcs
- directly. Still work in progress (i.e. not part of the official
- API). See the file <freetype/ftstroker.h> for some of the
- details.
-
- - The massive re-formatting of sources and internal re-design is
- still under-way. Many internal functions, constants, and types
- have been renamed.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.2 and 2.1.1
-
- I. IMPORTANT BUG FIXES
-
- - Many font drivers didn't select a Unicode charmap by default
- when a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS
- options enabled), causing many applications to not be able to
- display text correctly with the 2.1.x releases.
-
- - The PFR driver had a bug in its composite loading code that
- produces incorrectly placed accents with many fonts.
-
- - The Type42 driver crashed sometimes due to a nasty bug.
-
- - The Type 1 custom encoding charmap didn't handle the case where
- the first glyph index wasn't 0.
-
- - A serious typo in the TrueType composite loader produced
- incorrectly placed glyphs in fonts like `Wingdings' and a few
- others.
-
-
- II. MISCELLANEOUS
-
- - The Win32 Visual C++ project file has been updated to include
- the PFR driver as well.
-
- - `freetype.m4' is now installed by default by `make install' on
- Unix systems.
-
- - The function FT_Get_PS_Font_Info now works with CID and Type42
- fonts as well.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.1 and 2.1.0
-
- I. IMPORTANT BUG FIXES
-
- - The `version_info' returned by `freetype-config' in 2.1.0
- returned an invalid value. It now returns 9:1:3 (2.0.9 returned
- 9:0:3).
-
- - Version 2.1.0 couldn't be linked against applications on Win32
- and Amiga systems due to a new debug function that wasn't
- properly propagated to the system-specific directory in
- `builds'.
-
- - Various MacOS and Mac OS X specific fixes.
-
- - Fixed a bug in the TrueType charmap validation routines that
- made version 2.1.0 too restrictive -- many popular fonts have
- been rejected.
-
- - There was still a very small difference between the monochrome
- glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the
- bytecode interpreter enabled. This was caused by an invalid
- flag setting in the TrueType glyph loader, making the rasterizer
- change its drop-out control mode. Now the results should
- _really_ be completely identical.
-
- - The TrueType name table loader has been improved to support many
- popular though buggy Asian fonts. It now ignores empty name
- entries, invalid pointer offsets and a few other incorrect
- subtleties. Moreover, name strings are now loaded on demand,
- which reduces the memory load of many faces (e.g. the ARIAL.TTF
- font file contains a 10kByte name table with 70 names).
-
- - Fixed a bug in the Postscript hinter that prevented family blues
- substitution to happen correctly.
-
-
- II. NEW FEATURES
-
- - Three new font drivers in this release:
-
- * A BDF font driver, contributed by Franco Zappa Nardelli,
- heavily modified by Werner Lemberg. It also supports
- anti-aliased bitmaps (using a slightly extended BDF format).
-
- * A Type42 font driver, contributed by Roberto Alameda. It is
- still experimental but seems to work relatively well.
-
- * A PFR font driver, contributed by David Turner himself. It
- doesn't support PFR hinting -- note that BitStream has at
- least two patents on this format!
-
-
- III. MISCELLANEOUS
-
- - The cache sub-system has been optimized in important ways.
- Cache hits are now significantly faster. For example, using the
- CMap cache is about twice faster than calling FT_Get_Char_Index
- on most platforms. Similarly, using an SBit cache is about five
- times faster than loading the bitmaps from a bitmap file, and
- 300 to 500 times faster than generating them from a scalable
- format.
-
- Note that you should recompile your sources if you designed a
- custom cache class for the FT2 Cache subsystem, since the
- changes performed are source, but not binary, compatible.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.1.0 and 2.0.9
-
- I. IMPORTANT BUG FIXES
-
- - The TrueType bytecode interpreter has been fixed to produce
- _exactly_ the same output as FreeType 1.x. Previous differences
- were due to slightly distinct fixed-point computation routines
- used to perform dot products and vector length measurements.
-
- It seems that native TrueType hinting is _extremely_ sensitive
- to rounding errors. The required vector computation routines
- have been optimized and placed within the `ttinterp.c' file.
-
- - Fixed the parsing of accelerator tables in the PCF font driver.
-
- - Fixed the Type1 glyph loader routine used to compute the font's
- maximum advance width.
-
-
- II. NEW FEATURES
-
- - The `configure' script used on Unix systems has been modified to
- check that GNU Make is being used to build the library.
- Otherwise, it will display a message proposing to use the
- GNUMAKE environment variable to name it.
-
- The Unix-specific file README.UNX has been modified accordingly.
-
-
- III. MISCELLANEOUS
-
- - The FreeType License in `docs/FTL.TXT' has been updated to
- include a proposed preferred disclaimer. If you are using
- FreeType in your products, you are encouraged (but not mandated)
- to use the following text in your documentation:
-
- """
- Portions of this software are copyright © 1996-2002 The
- FreeType Project (www.freetype.org). All rights reserved.
- """
-
- - The default size of the render pool has been reduced to 16kByte.
- This shouldn't result in any noticeable performance penalty,
- unless you are using the engine as-is to render very large and
- complex glyphs.
-
- - The FreeType 2 redesign has begun. More information can be
- found at this URL:
-
- http://www.freetype.org/freetype2/redesign.html
-
- The following internal changes have been performed within the
- sources of this release:
-
- - Many internal types have been renamed to increase
- consistency. The following should be true, except for
- public types:
-
- * All structure types have a name ending in `Rec' (short
- for `record').
-
- * A pointer-to-structure type has the same name as the
- structure, _without_ the `Rec' suffix.
-
- Example:
-
- typedef struct FooRec_
- {
- ...
-
- } FooRec, *Foo;
-
- - Many internal macros have been renamed to increase
- consistency. The following should be true:
-
- * All macros have a name beginning with `FT_'. This
- required a few changes like
-
- ALLOC => FT_ALLOC
- FREE => FT_FREE
- REALLOC => FT_REALLOC
-
- * All macros are completely UPPERCASE. This required a
- few changes like:
-
- READ_Short => FT_READ_SHORT
- NEXT_Short => FT_NEXT_SHORT
- GET_ULongLE => FT_GET_ULONG_LE
- MEM_Set => FT_MEM_SET
- MEM_Copy => FT_MEM_COPY
- etc.
-
- * Whenever possible, all macro names follow the
- FT_<OBJECT>_<METHOD> pattern. For example
-
- ACCESS_Frame => FT_FRAME_ENTER
- FORGET_Frame => FT_FRAME_EXIT
- EXTRACT_Frame => FT_FRAME_EXTRACT
- RELEASE_Frame => FT_FRAME_RELEASE
-
- FILE_Pos => FT_STREAM_POS
- FILE_Seek => FT_STREAM_SEEK
- FILE_Read => FT_STREAM_READ
- FILE_ReadAt => FT_STREAM_READ_AT
- READ_Fields => FT_STREAM_READ_FIELDS
-
- - Many internal functions have been renamed to follow the
- FT_<Object>_<Method> pattern. For example:
-
- FT_Seek_Stream => FT_Stream_Seek
- FT_Read_Stream_At => FT_Stream_ReadAt
- FT_Done_Stream => FT_Stream_Close
- FT_New_Stream => FT_Stream_Open
- FT_New_Memory_Stream => FT_Stream_OpenMemory
- FT_Extract_Frame => FT_Stream_ExtractFrame
-
- Note that method names do not contain `_'.
-
- - The FT_ALLOC_ARRAY and FT_REALLOC_ARRAY have been replaced
- with FT_NEW_ARRAY and FT_RENEW_ARRAY which do not take a
- type as the fourth argument. Instead, the array element
- type size is computed automatically from the type of the
- target pointer used.
-
- - A new object class, FT_CMap, has been introduced. These
- internal objects are used to model character maps. This
- eases the support of additional charmap types within the
- engine.
-
- - A new configuration file named `ftstdlib.h' has been added
- to `include/freetype/config'. It is used to define aliases
- for _every_ routine of the ISO C library that the font
- engine uses. Each aliases has a `ft_' prefix
- (e.g. `ft_strlen' is an alias for `strlen').
-
- This is used to ease the porting of FreeType 2 to exotic
- runtime environments where the ISO C Library isn't available
- (e.g. XFree86 extension modules).
-
- More details are available in the `ChangeLog' file.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.9 and 2.0.8
-
- I. IMPORTANT BUG FIXES
-
- - Certain fonts like `foxjump.ttf' contain broken name tables with
- invalid entries and wild offsets. This caused FreeType to crash
- when trying to load them.
-
- The SFNT `name' table loader has been fixed to be able to
- support these strange fonts.
-
- Moreover, the code in charge of processing this table has been
- changed to always favour Windows-formatted entries over other
- ones. Hence, a font that works on Windows but not on the Mac
- will load cleanly in FreeType and report accurate values for
- Family & PostScript names.
-
- - The CID font driver has been fixed. It unfortunately returned a
- Postscript Font name with a leading slash, as in
- `/MunhwaGothic-Regular'.
-
- - FreeType 2 should now compile fine on AIX 4.3.3 as a shared
- library.
-
- - A bug in the Postscript hinter has been found and fixed,
- removing un-even stem widths at small pixel sizes (like 14-17).
-
- This improves the quality of a certain number of Postscript
- fonts.
-
-
- II. NEW FEATURES
-
- - A new function named `FT_Library_Version' has been added to
- return the current library's major, minor, and patch version
- numbers. This is important since the macros FREETYPE_MAJOR,
- FREETYPE_MINOR, and FREETYPE_PATCH cannot be used when the
- library is dynamically linked by a program.
-
- - Two new APIs have been added: `FT_Get_First_Char' and
- `FT_Get_Next_Char'.
-
- Together, these can be used to iterate efficiently over the
- currently selected charmap of a given face. Read the API
- reference for more details.
-
-
- III. MISCELLANEOUS
-
- - The FreeType sources are under heavy internal re-factoring. As
- a consequence, we have created a branch named `STABLE' on the
- CVS to hold all future releases/fixes in the 2.0.x family.
-
- The HEAD branch now contains the re-factored sources and
- shouldn't be used for testing or packaging new releases. In
- case you would like to access the 2.0.9 sources from our CVS
- repository, use the tag `VER-2-0-9'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.8 and 2.0.7
-
- I. IMPORTANT BUG FIXES
-
- - There was a small but nasty bug in `freetype-config.in' which
- caused the `freetype-config' script to fail on Unix.
-
- This didn't prevent the installation of the library or even its
- execution, but caused problems when trying to compile many Unix
- packages that depend on it.
-
- - Some TrueType or OpenType fonts embedded in PDF documents do not
- have a 'cmap', 'post' and 'name' as is required by the
- specification. FreeType no longer refuses to load such fonts.
-
- - Various fixes to the PCF font driver.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.7 and 2.0.6
-
- I. IMPORTANT BUG FIXES
-
- - Fixed two bugs in the Type 1 font driver. The first one
- resulted in a memory leak in subtle cases. The other one caused
- FreeType to crash when trying to load `.gsf' files (Ghostscript
- so-called Postscript fonts).
-
- (This made _many_ KDE applications crash on certain systems.
- FreeType _is_ becoming a critical system component on Linux :-)
-
- - Fixed a memory leak in the CFF font driver.
-
- - Fixed a memory leak in the PCF font driver.
-
- - Fixed the Visual C++ project file
- `builds/win32/visualc/freetype.dsp' since it didn't include the
- Postscript hinter component, causing errors at build time.
-
- - Fixed a small rendering bug in the anti-aliased renderer that
- only occurred when trying to draw thin (less than 1 pixel)
- strokes.
-
- - Fixed `builds/unix/freetype2.a4' which is used to generate a
- valid `freetype2.m4' for use with autoconf.
-
- - Fixed the OpenVMS Makefiles.
-
-
- II. MISCELLANEOUS
-
- - Added `configure' and `install' scripts to the top-level
- directory. A GNU-style installation is thus now easily possible
- with
-
- ./configure <options>
- make
- make install
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.6 and 2.0.5
-
- I. IMPORTANT BUG FIXES
-
- - It wasn't possible to load embedded bitmaps when the auto-hinter
- was used. This is now fixed.
-
- - The TrueType font driver didn't load some composites properly
- (the sub-glyphs were slightly shifted, and this was only
- noticeable when using monochrome rendering).
-
- - Various fixes to the auto-hinter. They merely improve the
- output of sans-serif fonts. Note that there are still problems
- with serifed fonts and composites (accented characters).
-
- - All scalable font drivers erroneously returned un-fitted glyph
- advances when hinting was requested. This created problems for
- a number of layout applications. This is a very old bug that
- got undetected mainly because most test/demo program perform
- rounding explicitly or implicitly (through the cache).
-
- - `FT_Glyph_To_Bitmap' did erroneously modify the source glyph in
- certain cases.
-
- - `glnames.py' still contained a bug that made FreeType return
- invalid names for certain glyphs.
-
- - The library crashed when loading certain Type 1 fonts like
- `sadn.pfb' (`Stalingrad Normal'), which appear to contain
- pathetic font info dictionaries.
-
- - The TrueType glyph loader is now much more paranoid and checks
- everything when loading a given glyph image. This was necessary
- to avoid problems (crashes and/or memory overwrites) with broken
- fonts that came from a really buggy automatic font converter.
-
-
- II. IMPORTANT UPDATES AND NEW FEATURES
-
- - Important updates to the Mac-specific parts of the library.
-
- - The caching sub-system has been completely re-designed, and its
- API has evolved (the old one is still supported for backward
- compatibility).
-
- The documentation for it is not yet completed, sorry. For now,
- you are encouraged to continue using the old API. However, the
- ftview demo program in the ft2demos package has already been
- updated to use the new caching functions.
-
- - A new charmap cache is provided too. See `FTC_CMapCache'. This
- is useful to perform character code -> glyph index translations
- quickly, without the need for an opened FT_Face.
-
- - A NEW POSTSCRIPT HINTER module has been added to support native
- hints in the following formats: PostScript Type 1, PostScript
- CID, and CFF/CEF.
-
- Please test! Note that the auto-hinter produces better results
- for a number of badly-hinted fonts (mostly auto-generated ones)
- though.
-
- - A memory debugger is now part of the standard FreeType sources.
- To enable it, define FT_DEBUG_MEMORY in
- <freetype/config/ftoption.h>, and recompile the library.
-
- Additionally, define the _environment_ variable FT_DEBUG_MEMORY
- and run any program using FreeType. When the library is exited,
- a summary of memory footprints and possible leaks will be
- displayed.
-
- This works transparently with _any_ program that uses FreeType.
- However, you will need a lot of memory to use this (allocated
- blocks are never released to the heap to detect double deletes
- easily).
-
-
- III. MISCELLANEOUS
-
- - We are aware of subtle differences between the output of
- FreeType versions 1 and 2 when it comes to monochrome
- TrueType-hinted glyphs. These are most probably due to small
- differences in the monochrome rasterizers and will be worked out
- in an upcoming release.
-
- - We have decided to fork the sources in a `stable' branch, and an
- `unstable' one, since FreeType is becoming a critical component
- of many Unix systems.
-
- The next bug-fix releases of the library will be named 2.0.7,
- 2.0.8, etc., while the `2.1' branch will contain a version of
- the sources where we will start major reworking of the library's
- internals, in order to produce FreeType 2.2.0 (or even 3.0) in a
- more distant future.
-
- We also hope that this scheme will allow much more frequent
- releases than in the past.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.5 and 2.0.4
-
- NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER. THIS MODULE
- WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1)
-
- - Fixed a bug that made certain glyphs, like `Cacute', `cacute' and
- `lslash' unavailable from Unicode charmaps of Postscript fonts.
- This prevented the correct display of Polish text, for example.
-
- - The kerning table of Type 1 fonts was loaded by FreeType, when its
- AFM file was attached to its face, but the
- FT_FACE_FLAG_HAS_KERNING bit flags was not set correctly,
- preventing FT_Get_Kerning to return meaningful values.
-
- - Improved SFNT (TrueType & OpenType) charmap support. Slightly
- better performance, as well as support for the new formats defined
- by the OpenType 1.3 specification (8, 10, and 12)
-
- - Fixed a serious typo in `src/base/ftcalc.c' which caused invalid
- computations in certain rare cases, producing ugly artefacts.
-
- - The size of the EM square is computed with a more accurate
- algorithm for Postscript fonts. The old one caused slight errors
- with embedded fonts found in PDF documents.
-
- - Fixed a bug in the cache manager that prevented normal LRU
- behaviour within the cache manager, causing unnecessary reloads
- (for FT_Face and FT_Size objects only).
-
- - Added a new function named `FT_Get_Name_Index' to retrieve the
- glyph index of a given glyph name, when found in a face.
-
- - Added a new function named `FT_Get_Postscript_Name' to retrieve
- the `unique' Postscript font name of a given face.
-
- - Added a new public header size named FT_SIZES_H (or
- <freetype/ftsizes.h>) providing new FT_Size-management functions:
- FT_New_Size, FT_Activate_Size, FT_Done_Size.
-
- - Fixed a reallocation bug that generated a dangling pointer (and
- possibly memory leaks) with Postscript fonts (in
- src/psaux/psobjs.c).
-
- - Many fixes for 16-bit correctness.
-
- - Removed many pedantic compiler warnings from the sources.
-
- - Added an Amiga build directory in `builds/amiga'.
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.4 and 2.0.3
-
- - Fixed a rather annoying bug that was introduced in 2.0.3. Namely,
- the font transformation set through FT_Set_Transform was applied
- twice to auto-hinted glyphs, resulting in incorrectly rotated text
- output.
-
- - Fixed _many_ compiler warnings. FT2 should now compile cleanly
- with Visual C++'s most pedantic warning level (/W4). It already
- compiled fine with GCC and a few other compilers.
-
- - Fixed a bug that prevented the linear advance width of composite
- TrueType glyphs to be correctly returned.
-
- - Fixed the Visual C++ project files located in
- `builds/win32/visualc' (previous versions used older names of the
- library).
-
- - Many 32-bit constants have an `L' appended to their value, in
- order to improve the 16-bitness of the code. Someone is actually
- trying to use FT2 on an Atari ST machine!
-
- - Updated the `builds/detect.mk' file in order to automatically
- build FT2 on AIX systems. AIX uses `/usr/sbin/init' instead of
- `/sbin/init' and wasn't previously detected as a Unix platform by
- the FreeType build system.
-
- - Updated the Unix-specific portions of the build system (new
- libtool version, etc.).
-
- - The SFNT kerning loader now ensures that the table is sorted
- (since some problem fonts do not meet this requirement).
-
-
-=======================================================================
-
-CHANGES BETWEEN 2.0.3 and 2.0.2
-
- I. CHANGES TO THE MODULES / FONT DRIVERS
-
- - THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix
- several annoying artefacts, mainly:
-
- - Blue zone alignment of horizontal stems wasn't performed
- correctly, resulting in artefacts like the `d' being placed
- one pixel below the `b' in some fonts like Time New Roman.
-
- - Overshoot thresholding wasn't performed correctly, creating
- unpleasant artefacts at large character pixel sizes.
-
- - Composite glyph loading has been simplified. This gets rid
- of various artefacts where the components of a composite
- glyphs were not correctly spaced.
-
- These are the last changes to the current auto-hinting module.
- A new hinting sub-system is currently in the work in order to
- support native hints in Type 1 / CFF / OpenType fonts, as well
- as globally improve rendering.
-
- - The PCF driver has been fixed. It reported invalid glyph
- dimensions for the fonts available on Solaris.
-
- - The Type 1, CID and CFF drivers have been modified to fix the
- computation of the EM size.
-
- - The Type 1 driver has been fixed to avoid a dangerous bug that
- crashed the library with non-conforming fonts (i.e. ones that do
- not place the .notdef glyph at position 0).
-
- - The TrueType driver had a rather subtle bug (dangling pointer
- when loading composite glyphs) that could crash the library in
- rare occasions!
-
-
- II. HIGH-LEVEL API CHANGES
-
- - The error code enumeration values have been changed. An error
- value is decomposed in a generic error code, and a module
- number. see <freetype/fterrors.h> for details.
-
- - A new public header file has been introduced, named
- FT_TRIGONOMETRY_H (include/freetype/fttrigon.h), providing
- trigonometric functions to compute sines, cosines, arctangents,
- etc. with 16.16 fixed precision. The implementation is based on
- the CORDIC algorithm and is very fast while being sufficiently
- accurate.
-
-
- III. INTERNALS
-
- - Added BeOS-specific files in the old build sub-system. Note
- that no changes were required to compile the library with Jam.
-
- - The configuration is now capable of automatically detecting
- 64-bit integers on a set of predefined compilers (GCC, Visual
- C++, Borland C++) and will use them by default. This provides a
- small performance boost.
-
- - A small memory leak that happened when opening 0-sized files
- (duh!) have been fixed.
-
- - Fixed bezier stack depth bug in the routines provided by the
- FT_BBOX_H header file. Also fixed similar bugs in the
- rasterizers.
-
- - The outline bounding box code has been rewritten to use direct
- computations, instead of bezier sub-division, to compute the
- exact bounding box of glyphs. This is slightly slower but more
- accurate.
-
- - The build system has been improved and fixed, mainly to support
- `make' on Windows 2000 correctly, avoid problems with `make
- distclean' on non Unix systems, etc.
-
- - Hexadecimal constants have been suffixed with `U' to avoid
- problems with certain compilers on 64-bit platforms.
-
- - A new directory named `src/tools' has been created. It contains
- Python scripts and simple unit test programs used to develop the
- library.
-
- - The DocMaker tool has been moved from `docs' to `src/tools' and
- has been updated with the following:
-
- - Now accepts the `--title=XXXX' or `-t XXXX' option from the
- command line to set the project's name in the generated API
- reference.
-
- - Now accepts the `--output=DIR' or `-o DIR' option from the
- command line to set the output directory for all generated
- HTML files.
-
- - Now accepts the `--prefix=XXXX' or `-p XXX' option from the
- command line to set the file prefix to use for all
- generated HTML files.
-
- - Now generates the current time/data on each generated page
- in order to distinguish between versions.
-
- DocMaker can be used with other projects now, not only FT2
- (e.g. MLib, FTLayout, etc.).
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.2 and 2.0.1
-
- I. CHANGES TO THE MODULES / FONT DRIVERS
-
- - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to
- avoid legal problems with the Apple patents. It seems that we
- mistakenly turned this option on in previous releases of the
- build.
-
- Note that if you want to use the bytecode interpreter in order
- to get high-quality TrueType rendering, you will need to toggle
- by hand the definition of the
- TT_CONFIG_OPTION_BYTECODE_INTERPRETER macro in the file
- `include/freetype/config/ftoption.h'.
-
- - The CFF driver has been improved by Tom Kacvinsky and Sander van
- der Wal:
-
- * Support for `seac' emulation.
- * Support for `dotsection'.
- * Support for retrieving glyph names through
- `FT_Get_Glyph_Name'.
-
- The first two items are necessary to correctly a large number of
- Type 1 fonts converted to the CFF formats by Adobe Acrobat.
-
- - The Type 1 driver was also improved by Tom & others:
-
- * Better EM size computation.
- * Better support for synthetic (transformed) fonts.
- * The Type 1 driver returns the charstrings corresponding to
- each glyph in the `glyph->control_data' field after a call to
- `FT_Load_Glyph' (thanks Ha Shao).
-
- - Various other bugfixes, including the following:
-
- * Fixed a nasty memory leak in the Type 1 driver.
- * The autohinter and the pcf driver used static writable data
- when they shouldn't.
- * Many casts were added to make the code more 64-bits safe. It
- also now compiles on Windows XP 64-bits without warnings.
- * Some incorrect writable statics were removed in the `autohint'
- and `pcf' drivers. FreeType 2 now compiles on Epoc again.
-
-
- II. CHANGES TO THE HIGH-LEVEL API
-
- - The library header files inclusion scheme has been changed. The
- old scheme looked like:
-
- #include <freetype/freetype.h>
- #include <freetype/ftglyph.h>
- #include <freetype/ftcache.h>
- #include <freetype/cache/ftimage.h>
-
- Now you should use:
-
- #include <ft2build.h>
- #include FT_FREETYPE_H
- #include FT_GLYPH_H
- #include FT_CACHE_H
- #include FT_CACHE_IMAGE_H
-
- NOTE THAT THE OLD INCLUSION SCHEME WILL STILL WORK WITH THIS
- RELEASE. HOWEVER, WE DO NOT GUARANTEE THAT THIS WILL STILL BE
- TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1).
-
- The file <ft2build.h> is used to define the header filename
- macros. The complete and commented list of macros is available
- in the API reference under the section name `Header File Macros'
- in Chapter I.
-
- For more information, see section I of the following document:
-
- http://www.freetype.org/
- freetype2/docs/tutorial/step1.html
-
- or
-
- http://freetype.sourceforge.net/
- freetype2/docs/tutorial/step1.html
-
- - Many, many comments have been added to the public source file in
- order to automatically generate the API Reference through the
- `docmaker.py' Python script.
-
- The latter has been updated to support the grouping of sections
- in chapters and better index sort. See:
-
- http://www.freetype.org/freetype2/docs/reference/ft2-toc.html
-
-
- III. CHANGES TO THE BUILD PROCESS
-
- - If you are not building FreeType 2 with its own build system
- (but with your own Makefiles or project files), you will need to
- be aware that the build process has changed a little bit.
-
- You don't need to put the `src' directory in the include path
- when compiling any FT2 component. Instead, simply put the
- component's directory in the current include path.
-
- So, if you were doing something like:
-
- cc -c -Iinclude -Isrc src/base/ftbase.c
-
- change the line to:
-
- cc -c -Iinclude -Isrc/base src/base/ftbase.c
-
- If you were doing something like:
-
- cd src/base
- cc -c -I../../include -I.. ftbase.c
-
- change it to:
-
- cd src/base
- cc -c -I../../include ftbase.c
-
-
-======================================================================
-
-CHANGES BETWEEN 2.0.1 and 2.0
-
- 2.0.1 introduces a few changes:
-
- - Fixed many bugs related to the support of CFF / OpenType fonts.
- These formats are now much better supported though there is
- still work planned to deal with charset tables and PDF-embedded
- CFF files that use the old `seac' command.
-
- - The library could not be compiled in debug mode with a very
- small number of C compilers whose pre-processors didn't
- implement the `##' directive correctly (i.e. per se the ANSI C
- specification!) An elegant fix was found.
-
- - Added support for the free Borland command-line C++ Builder
- compiler. Use `make setup bcc32'. Also fixed a few source
- lines that generated new warnings with BCC32.
-
- - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of
- a conic Bezier arc.
-
- - Updated the INSTALL file to add IDE compilation.
-
- - Other minor bug fixes, from invalid Type 1 style flags to
- correct support of synthetic (obliqued) fonts in the
- auto-hinter, better support for embedded bitmaps in a SFNT font.
-
- - Fixed some problems with `freetype-config'.
-
- Finally, the `standard' scheme for including FreeType headers is now
- gradually changing, but this will be explained in a later release
- (probably 2.0.2).
-
- And very special thanks to Tom Kacvinsky and YAMANO-UCHI Hidetoshi
- for their contributions!
-
-
-======================================================================
-
-CHANGES BETWEEN beta8 and 2.0
-
- - Changed the default installation path for public headers from
- `include/freetype' to `include/freetype2'.
-
- Also added a new `freetype-config' that is automatically generated
- and installed on Unix and Cygwin systems. The script itself is
- used to retrieve the current install path, C compilation flags as
- well as linker flags.
-
- - Fixed several small bugs:
-
- * Incorrect max advance width for fixed-pitch Type 1 fonts.
- * Incorrect glyph names for certain TrueType fonts.
- * The glyph advance was not copied when FT_Glyph_To_Bitmap was
- called.
- * The linearHoriAdvance and linearVertAdvance fields were not
- correctly returned for glyphs processed by the auto-hinter.
- * `type1z' renamed back to `type1'; the old `type1' module has
- been removed.
-
- - Revamped the build system to make it a lot more generic. This
- will allow us to re-use nearly un-modified in lots of other
- projects (including FreeType Layout).
-
- - Changed `cid' to use `psaux' too.
-
- - Added the cache sub-system. See <freetype/ftcache.h> as well as
- the sources in `src/cache'. Note that it compiles but is still
- untested for now.
-
- - Updated `docs/docmaker.py', a draft API reference is available at
- http://www.freetype.org/ft2api.html.
-
- - Changed `type1' to use `psaux'.
-
- - Created a new module named `psaux' to hold the Type 1 & Type 2
- parsing routines. It should be used by `type1', `cid', and `cff'
- in the future.
-
- - Fixed an important bug in `FT_Glyph_Get_CBox'.
-
- - Fixed some compiler warnings that happened since the TrueType
- bytecode decoder was deactivated by default.
-
- - Fixed two memory leaks:
-
- * The memory manager (16 bytes) isn't released in
- FT_Done_FreeType!
- * Using custom input streams, the copy of the original stream was
- never released.
-
- - Fixed the auto-hinter by performing automatic computation of the
- `filling direction' of each glyph. This is done through a simple
- and fast approximation, and seems to work (problems spotted by
- Werner though). The Arphic fonts are a lot nicer though there are
- still a lot of things to do to handle Asian fonts correctly.
-
-
-======================================================================
-
-BETA-8 (RELEASE CANDIDATE) CHANGES
-
- - Deactivated the TrueType bytecode interpreter by default.
-
- - Deactivated the `src/type1' font driver. Now `src/type1z' is used
- by default.
-
- - Updates to the build system. We now compile the library correctly
- under Unix system through `configure' which is automatically
- called on the first `make' invocation.
-
- - Added the auto-hinting module! Fixing some bugs here and there.
-
- - Found some bugs in the composite loader (seac) of the Type1-based
- font drivers.
-
- - Renamed the directory `freetype2/config' to `freetype2/builds' and
- updated all relevant files.
-
- - Found a memory leak in the `type1' driver.
-
- - Incorporated Tom's patches to support flex operators correctly in
- OpenType/CFF fonts. Now all I need is to support pure CFF and CEF
- fonts to be done with this driver :-)
-
- - Added the Windows FNT/FON driver in `src/winfonts'. For now, it
- always `simulates' a Unicode charmap, so it shouldn't be
- considered completed right now.
-
- It is there to be more a proof of concept than anything else
- anyway. The driver is a single C source file, that compiles to 3
- Kb of code.
-
- I'm still working on the PCF/BDF drivers, but I'm too lazy to
- finish them now.
-
- - CHANGES TO THE HIGH-LEVEL API
-
- * FT_Get_Kerning has a new parameter that allows you to select the
- coordinates of the kerning vector (font units, scaled, scaled +
- grid-fitted).
- * The outline functions are now in <freetype/ftoutln.h> and not
- part of <freetype/freetype.h> anymore.
- * <freetype/ftmodule.h> now contains declarations for
- FT_New_Library, FT_Done_Library, FT_Add_Default_Modules.
- * The so-called convenience functions have moved from `ftoutln.c'
- to `ftglyph.c', and are thus available with this optional
- component of the library. They are declared in
- <freetype/ftglyph.h> now.
- * Anti-aliased rendering is now the default for FT_Render_Glyph
- (i.e. corresponds to render_mode == 0 == ft_render_mode_normal).
- To generate a monochrome bitmap, use ft_render_mode_mono, or the
- FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char.
- FT_LOAD_ANTI_ALIAS is still defined, but values to 0.
- * <freetype/freetype.h> now include <freetype/config/ftconfig.h>,
- solving a few headaches :-)
- * The type FT_GlyphSlotRec has now a `library' field.
-
- - CHANGES TO THE `ftglyph.h' API
-
- This API has been severely modified in order to make it simpler,
- clearer, and more efficient. It certainly now looks like a real
- `glyph factory' object, and allows client applications to manage
- (i.e. transform, bbox and render) glyph images without ever
- knowing their original format.
-
- - Added support for CID-keyed fonts to the CFF driver. Maybe
- support for pure CFF + CEF fonts should come in?
-
- - Cleaned up source code in order to avoid two functions with the
- same name. Also changed the names of the files in `type1z' from
- `t1XXXX' to `z1XXXX' in order to avoid any conflicts.
-
- `make multi' now works well :-)
-
- Also removed the use of `cidafm' for now, even if the source files
- are still there. This functionality will certainly go into a
- specific module.
-
- - ADDED SUPPORT FOR THE AUTO-HINTER
-
- It works :-) I have a demo program which simply is a copy of
- `ftview' that does a `FT_Add_Module(library,
- &autohinter_module_class)' after library initialization, and Type
- 1 & OpenType/CFF fonts are now hinted.
-
- CID fonts are not hinted, as they include no charmap and the
- auto-hinter doesn't include `generic' global metrics computations
- yet.
-
- Now, I need to release this thing to the FreeType 2 source.
-
- - CHANGES TO THE RENDERER MODULES
-
- The monochrome and smooth renderers are now in two distinct
- directories, namely `src/raster1' and `src/smooth'. Note that the
- old `src/renderer' is now gone.
-
- I ditched the 5-gray-levels renderers. Basically, it involved a
- simple #define toggle in 'src/raster1/ftraster.c'.
-
- FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now
- select the best renderer available, depending on render mode. If
- the current renderer for a given glyph image format isn't capable
- of supporting the render mode, another one will be found in the
- library's list. This means that client applications do not need
- to switch or set the renderers themselves (as in the latest
- change), they'll get what they want automatically. At last.
-
- Changed the demo programs accordingly.
-
- - MAJOR INTERNAL REDESIGN:
-
- A lot of internal modifications have been performed lately on the
- source in order to provide the following enhancements:
-
- * More generic module support:
-
- The FT_Module type is now defined to represent a handle to a
- given module. The file <freetype/ftmodule.h> contains the
- FT_Module_Class definition, as well as the module-loading public
- API.
-
- The FT_Driver type is still defined, and still represents a
- pointer to a font driver. Note that FT_Add_Driver is replaced
- by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc.
-
- * Support for generic glyph image types:
-
- The FT_Renderer type is a pointer to a module used to perform
- various operations on glyph image.
-
- Each renderer is capable of handling images in a single format
- (e.g. ft_glyph_format_outline). Its functions are used to:
-
- - transform an glyph image
- - render a glyph image into a bitmap
- - return the control box (dimensions) of a given glyph image
-
- The scan converters `ftraster.c' and `ftgrays.c' have been moved
- to the new directory `src/renderer', and are used to provide two
- default renderer modules.
-
- One corresponds to the `standard' scan-converter, the other to
- the `smooth' one.
-
- he current renderer can be set through the new function
- FT_Set_Renderer.
-
- The old raster-related function FT_Set_Raster, FT_Get_Raster and
- FT_Set_Raster_Mode have now disappeared, in favor of the new:
-
- FT_Get_Renderer
- FT_Set_Renderer
-
- See the file <freetype/ftrender.h> for more details.
-
- These changes were necessary to properly support different
- scalable formats in the future, like bi-color glyphs, etc.
-
- * Glyph loader object:
-
- A new internal object, called a 'glyph loader' has been
- introduced in the base layer. It is used by all scalable format
- font drivers to load glyphs and composites.
-
- This object has been created to reduce the code size of each
- driver, as each one of them basically re-implemented its
- functionality.
-
- See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
- more information.
-
- * FT_GlyphSlot has new fields:
-
- In order to support extended features (see below), the
- FT_GlyphSlot structure has a few new fields:
-
- linearHoriAdvance:
-
- This field gives the linearly scaled (i.e. scaled but
- unhinted) advance width for the glyph, expressed as a 16.16
- fixed pixel value. This is useful to perform WYSIWYG text.
-
- linearVertAdvance:
- This field gives the linearly scaled advance height for the
- glyph (relevant in vertical glyph layouts only). This is
- useful to perform WYSIWYG text.
-
- Note that the two above field replace the removed `metrics2'
- field in the glyph slot.
-
- advance:
- This field is a vector that gives the transformed advance for
- the glyph. By default, it corresponds to the advance width,
- unless FT_LOAD_VERTICAL_LAYOUT was specified when calling
- FT_Load_Glyph or FT_Load_Char.
-
- bitmap_left:
- This field gives the distance in integer pixels from the
- current pen position to the left-most pixel of a glyph image
- IF IT IS A BITMAP. It is only valid when the `format' field
- is set to `ft_glyph_format_bitmap', for example, after calling
- the new function FT_Render_Glyph.
-
- bitmap_top:
- This field gives the distance in integer pixels from the
- current pen position (located on the baseline) to the top-most
- pixel of the glyph image IF IT IS A BITMAP. Positive values
- correspond to upwards Y.
-
- loader:
- This is a new private field for the glyph slot. Client
- applications should not touch it.
-
-
- * Support for transforms and direct rendering in FT_Load_Glyph:
-
- Most of the functionality found in <freetype/ftglyph.h> has been
- moved to the core library. Hence, the following:
-
- - A transform can be specified for a face through
- FT_Set_Transform. this transform is applied by FT_Load_Glyph
- to scalable glyph images (i.e. NOT TO BITMAPS) before the
- function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM
- was set in the load flags.
-
- - Once a glyph image has been loaded, it can be directly
- converted to a bitmap by using the new FT_Render_Glyph
- function. Note that this function takes the glyph image from
- the glyph slot, and converts it to a bitmap whose properties
- are returned in `face.glyph.bitmap', `face.glyph.bitmap_left'
- and `face.glyph.bitmap_top'. The original native image might
- be lost after the conversion.
-
- - When using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph
- and FT_Load_Char functions will call FT_Render_Glyph
- automatically when needed.
-
- - Reformatted all modules source code in order to get rid of the
- basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int',
- `T1_Fixed' instead of `FT_Fixed'). Hence the format-specific
- prefixes like `TT_', `T1_', `T2_' and `CID_' are only used for
- relevant structures.
-
-
-======================================================================
-
-OLD CHANGES FOR BETA 7
-
- - bug-fixed the OpenType/CFF parser. It now loads and displays my
- two fonts nicely, but I'm pretty certain that more testing is
- needed :-)
-
- - fixed the crummy Type 1 hinter, it now handles accented characters
- correctly (well, the accent is not always well placed, but that's
- another problem..)
-
- - added the CID-keyed Type 1 driver in `src/cid'. Works pretty well
- for only 13 Kb of code ;-) Doesn't read AFM files though, nor the
- really useful CMAP files..
-
- - fixed two bugs in the smooth renderer (src/base/ftgrays.c).
- Thanks to Boris Letocha for spotting them and providing a fix.
-
- - fixed potential `divide by zero' bugs in ftcalc.c.
-
- - added source code for the OpenType/CFF driver (still incomplete
- though..)
-
- - modified the SFNT driver slightly to perform more robust header
- checks in TT_Load_SFNT_Header. This prevents certain font files
- (e.g. some Type 1 Multiple Masters) from being incorrectly
- `recognized' as TrueType font files..
-
- - moved a lot of stuff from the TrueType driver to the SFNT module,
- this allows greater code re-use between font drivers
- (e.g. TrueType, OpenType, Compact-TrueType, etc..)
-
- - added a tiny segment cache to the SFNT Charmap 4 decoder, in order
- to minimally speed it up..
-
- - added support for Multiple Master fonts in `type1z'. There is
- also a new file named <freetype/ftmm.h> which defines functions to
- manage them from client applications.
-
- The new file `src/base/ftmm.c' is also optional to the engine..
-
- - various formatting changes (e.g. EXPORT_DEF -> FT_EXPORT_DEF) +
- small bug fixes in FT_Load_Glyph, the `type1' driver, etc..
-
- - a minor fix to the Type 1 driver to let them apply the font matrix
- correctly (used for many oblique fonts..)
-
- - some fixes for 64-bit systems (mainly changing some FT_TRACE calls
- to use %p instead of %lx). Thanks to Karl Robillard.
-
- - fixed some bugs in the sbit loader (src/base/sfnt/ttsbit.c) +
- added a new flag, FT_LOAD_CROP_BITMAP to query that bitmaps be
- cropped when loaded from a file (maybe I should move the bitmap
- cropper to the base layer ??).
-
- - changed the default number of gray levels of the smooth renderer
- to 256 (instead of the previous 128). Of course, the human eye
- can't see any difference ;-)
-
- - removed TT_MAX_SUBGLYPHS, there is no static limit on the number
- of subglyphs in a TrueType font now..

-OLD CHANGES 16 May 2000
-
- - tagged `BETA-6' in the CVS tree. This one is a serious release
- candidate even though it doesn't incorporate the auto-hinter yet..
-
- - various obsolete files were removed, and copyright header updated
-
- - finally updated the standard raster to fix the monochrome
- rendering bug + re-enable support for 5-gray levels anti-aliasing
- (suck, suck..)
-
- - created new header files, and modified sources accordingly:
-
- <freetype/fttypes.h>
- - simple FreeType types, without the API
- <freetype/internal/ftmemory.h>
- - definition of memory-management macros
-
- - added the `DSIG' (OpenType Digital Signature) tag to
- <freetype/tttags.h>
-
- - light update/cleaning of the build system + changes to the sources
- in order to get rid of _all_ compiler warnings with three
- compilers, i.e:
-
- gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and
- LCC
-
- IMPORTANT NOTE FOR WIN32-LCC USERS:
- |
- | It seems the C pre-processor that comes with LCC is broken, it
- | doesn't recognize the ANSI standard directives # and ##
- | correctly when one of the argument is a macro. Also,
- | something like:
- |
- | #define F(x) print##x
- |
- | F(("hello"))
- |
- | will get incorrectly translated to:
- |
- | print "hello")
- |
- | by its pre-processor. For this reason, you simply cannot build
- | FreeType 2 in debug mode with this compiler..
-
- - yet another massive grunt work. I've changed the definition of
- the EXPORT_DEF, EXPORT_FUNC, BASE_DEF & BASE_FUNC macros. These
- now take an argument, which is the function's return value type.
-
- This is necessary to compile FreeType as a DLL on Windows and
- OS/2. Depending on the compiler used, a compiler-specific keyword
- like __export or __system must be placed before (VisualC++) or
- after (BorlandC++) the type..
-
- Of course, this needed a lot of changes throughout the source code
- to make it compile again... All cleaned up now, apparently..
-
- Note also that there is a new EXPORT_VAR macro defined to allow
- the _declaration_ of an exportable public (constant)
- variable. This is the case of the raster interfaces (see
- ftraster.h and ftgrays.h), as well as each module's interface (see
- sfdriver.h, psdriver.h, etc..)
-
- - new feature: it is now possible to pass extra parameters to font
- drivers when creating a new face object. For now,
- this capability is unused. It could however prove to
- be useful in a near future..
-
- the FT_Open_Args structure was changes, as well as the internal
- driver interface (the specific `init_face' module function has
- now a different signature).
-
- - updated the tutorial (not finished though).
-
- - updated the top-level BUILD document
-
- - fixed a potential memory leak that could occur when loading
- embedded bitmaps.
-
- - added the declaration of FT_New_Memory_Face in
- <freetype/freetype.h>, as it was missing from the public header
- (the implementation was already in `ftobjs.c').
-
- - the file <freetype/fterrors.h> has been seriously updated in order
- to allow the automatic generation of error message tables. See
- the comments within it for more information.
-
- - major directory hierarchy re-organisation. This was done for two
- things:
-
- * first, to ease the `manual' compilation of the library by
- requiring at lot less include paths :-)
-
- * second, to allow external programs to effectively access
- internal data fields. For example, this can be extremely
- useful if someone wants to write a font producer or a font
- manager on top of FreeType.
-
- Basically, you should now use the 'freetype/' prefix for header
- inclusion, as in:
-
- #include <freetype/freetype.h>
- #include <freetype/ftglyph.h>
-
- Some new include sub-directories are available:
-
- a. the `freetype/config' directory, contains two files used to
- configure the build of the library. Client applications
- should not need to look at these normally, but they can if
- they want.
-
- #include <freetype/config/ftoption.h>
- #include <freetype/config/ftconfig.h>
-
- b. the `freetype/internal' directory, contains header files that
- describes library internals. These are the header files that
- were previously found in the `src/base' and `src/shared'
- directories.
-
-
- As usual, the build system and the demos have been updated to
- reflect the change..
-
- Here's a layout of the new directory hierarchy:
-
- TOP_DIR
- include/
- freetype/
- freetype.h
- ...
- config/
- ftoption.h
- ftconfig.h
- ftmodule.h
-
- internal/
- ftobjs.h
- ftstream.h
- ftcalc.h
- ...
-
- src/
- base/
- ...
-
- sfnt/
- psnames/
- truetype/
- type1/
- type1z/
-
-
- Compiling a module is now much easier, for example, the following
- should work when in the TOP_DIR directory on an ANSI build:
-
- gcc -c -I./include -I./src/base src/base/ftbase.c
- gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c
- etc..
-
- (of course, using -Iconfig/<system> if you provide system-specific
- configuration files).
-
- - updated the structure of FT_Outline_Funcs in order to allow direct
- coordinate scaling within the outline decomposition routine (this
- is important for virtual `on' points with TrueType outlines) +
- updates to the rasters to support this..
-
- - updated the OS/2 table loading code in `src/sfnt/ttload.c' in
- order to support version 2 of the table (see OpenType 1.2 spec)
-
- - created `include/tttables.h' and `include/t1tables.h' to allow
- client applications to access some of the SFNT and T1 tables of a
- face with a procedural interface (see `FT_Get_Sfnt_Table') +
- updates to internal source files to reflect the change..
-
- - some cleanups in the source code to get rid of warnings when
- compiling with the `-Wall -W -ansi -pedantic' options in gcc.
-
- - debugged and moved the smooth renderer to `src/base/ftgrays.c' and
- its header to `include/ftgrays.h'
-
- - updated TT_MAX_SUBGLYPHS to 96 as some CJK fonts have composites
- with up to 80 sub-glyphs !! Thanks to Werner
-
-
-======================================================================
-
-OLD CHANGES - 14-apr-2000
-
- - fixed a bug in the TrueType glyph loader that prevented the
- correct loading of some CJK glyphs in mingli.ttf
-
- - improved the standard Type 1 hinter in `src/type1'
-
- - fixed two bugs in the experimental Type 1 driver in `src/type1z'
- to handle the new XFree86 4.0 fonts (and a few other ones..)
-
- - the smooth renderer is now complete and supports sub-banding to
- render large glyphs at high speed. However, it is still located
- in `demos/src/ftgrays.c' and should move to the library itself in
- the next beta. NOTE: The smooth renderer doesn't compile in
- stand-alone mode anymore, but this should be fixed RSN..
-
- - introduced convenience functions to more easily deal with glyph
- images, see `include/ftglyph.h' for more details, as well as the
- new demo program named `demos/src/ftstring.c' that demonstrates
- its use
-
- - implemented FT_LOAD_NO_RECURSE in both the TrueType and Type 1
- drivers (this is required by the auto-hinter to improve its
- results).
-
- - changed the raster interface, in order to allow client
- applications to provide their own span-drawing callbacks.
- However, only the smooth renderer supports this. See
- `FT_Raster_Params' in the file `include/ftimage.h'.
-
- - fixed a small bug in FT_MulFix that caused incorrect transform
- computation!
-
- - Note: The tutorial is out-of-date.
-
-
-======================================================================
-
-OLD CHANGES - 12-mar-2000
-
- - changed the layout of configuration files : now, all ANSI
- configuration files are located in
- `freetype2/config'. System-specific over-rides can be placed in
- `freetype2/config/<system>'.
-
- - moved all configuration macros to `config/ftoption.h'
-
- - improvements in the Type 1 driver with AFM support
-
- - changed the fields in the FT_Outline structure : the old `flags'
- array is re-named `tags', while all ancient flags are encoded into
- a single unsigned int named `flags'.
-
- - introduced new flags in FT_Outline.flags (see
- ft_outline_.... enums in `ftimage.h').
-
- - changed outline functions to `FT_Outline_<action>' syntax
-
- - added a smooth anti-alias renderer to the demonstration programs
-
- - added Mac graphics driver (thanks Just)
-
- - FT_Open_Face changed in order to received a pointer to a
- FT_Open_Args descriptor..
-
- - various cleanups, a few more API functions implemented (see
- FT_Attach_File)
-
- - updated some docs
-
-
-======================================================================
-
-OLD CHANGES - 22-feb-2000
-
- - introduced the `psnames' module. It is used to:
-
- o convert a Postscript glyph name into the equivalent Unicode
- character code (used by the Type 1 driver(s) to synthesize on
- the fly a Unicode charmap).
-
- o provide an interface to retrieve the Postscript names of the
- Macintosh, Adobe Standard & Adobe Expert character codes.
- (the Macintosh names are used by the SFNT-module postscript
- names support routines, while the other two tables are used by
- the Type 1 driver(s)).
-
- - introduced the `type1z' alternate Type 1 driver. This is a (still
- experimental) driver for the Type 1 format that will ultimately
- replace the one in `src/type1'. It uses pattern matching to load
- data from the font, instead of a finite state analyzer. It works
- much better than the `old' driver with `broken' fonts. It is also
- much smaller (under 15 Kb).
-
- - the Type 1 drivers (both in `src/type1' and `src/type1z') are
- nearly complete. They both provide automatic Unicode charmap
- synthesis through the `psnames' module. No re-encoding vector is
- needed. (note that they still leak memory due to some code
- missing, and I'm getting lazy).
-
- Trivial AFM support has been added to read kerning information but
- wasn't exactly tested as it should ;-)
-
- - The TrueType glyph loader has been seriously rewritten (see the
- file `src/truetype/ttgload.c'. It is now much, much simpler as
- well as easier to read, maintain and understand :-) Preliminary
- versions introduced a memory leak that has been reported by Jack
- Davis, and is now fixed..
-
- - introduced the new `ft_glyph_format_plotter', used to represent
- stroked outlines like Windows `Vector' fonts, and certain Type 1
- fonts like `Hershey'. The corresponding raster will be written
- soon.
-
- - FT_New_Memory_Face is gone. Likewise, FT_Open_Face has a new
- interface that uses a structure to describe the input stream, the
- driver (if required), etc..
-
-
-TODO
-
- - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap
-
- - Add a function like FT_Load_Character(face, char_code, load_flags)
- that would really embed a call to FT_Get_Char_Index then
- FT_Load_Glyph to ease developer's work.
-
- - Update the tutorial!
-
- - consider adding support for Multiple Master fonts in the Type 1
- drivers.
-
- - Test the AFM routines of the Type 1 drivers to check that kerning
- information is returned correctly.
-
- - write a decent auto-gridding component !! We need this to release
- FreeType 2.0 gold !
-
-
-less urgent needs:
-
- - add a CFF/Type2 driver
- - add a BDF driver
- - add a FNT/PCF/HBF driver
- - add a Speedo driver from the X11 sources
-
-
-======================================================================
-
-OLDER CHANGES - 27-jan-2000
-
- - updated the `sfnt' module interface to allow several SFNT-based
- drivers to co-exist peacefully
-
- - updated the `T1_Face' type to better separate Postscript font
- content from the rest of the FT_Face structure. Might be used
- later by the CFF/Type2 driver..
-
- - added an experimental replacement Type 1 driver featuring advanced
- (and speedy) pattern matching to retrieve the data from postscript
- fonts.
-
- - very minor changes in the implementation of FT_Set_Char_Size and
- FT_Set_Pixel_Sizes (they now implement default to lighten the font
- driver's code).
-
-
-======================================================================
-
-OLD MESSAGE
-
-This file summarizes the changes that occurred since the last `beta'
-of FreeType 2. Because the list is important, it has been divided into
-separate sections:
-
-Table Of Contents:
-
- I High-Level Interface (easier !)
- II Directory Structure
- III Glyph Image Formats
- IV Build System
- V Portability
- VI Font Drivers
-
-
-----------------------------------------------------------------------
-
-High-Level Interface:
-
- The high-level API has been considerably simplified. Here is how:
-
- - resource objects have disappeared. this means that face objects
- can now be created with a single function call (see FT_New_Face
- and FT_Open_Face)
-
- - when calling either FT_New_Face & FT_Open_Face, a size object
- and a glyph slot object are automatically created for the face,
- and can be accessed through `face->glyph' and `face->size' if
- one really needs to. In most cases, there's no need to call
- FT_New_Size or FT_New_Glyph.
-
- - similarly, FT_Load_Glyph now only takes a `face' argument
- (instead of a glyph slot and a size). Also, its `result'
- parameter is gone, as the glyph image type is returned in the
- field `face->glyph.format'
-
- - the list of available charmaps is directly accessible through
- `face->charmaps', counting `face->num_charmaps' elements. Each
- charmap has an 'encoding' field which specifies which known
- encoding it deals with. Valid values are, for example:
-
- ft_encoding_unicode (for ASCII, Latin-1 and Unicode)
- ft_encoding_apple_roman
- ft_encoding_sjis
- ft_encoding_adobe_standard
- ft_encoding_adobe_expert
-
- other values may be added in the future. Each charmap still
- holds its `platform_id' and `encoding_id' values in case the
- encoding is too exotic for the current library
-
-
-----------------------------------------------------------------------
-
-Directory Structure:
-
- Should seem obvious to most of you:
-
- freetype/
- config/ -- configuration sub-makefiles
- ansi/
- unix/ -- platform-specific configuration files
- win32/
- os2/
- msdos/
-
- include/ -- public header files, those to be included
- directly by client apps
-
- src/ -- sources of the library
- base/ -- the base layer
- sfnt/ -- the sfnt `driver' (see the drivers section
- below)
- truetype/ -- the truetype driver
- type1/ -- the type1 driver
- shared/ -- some header files shared between drivers
-
- demos/ -- demos/tools
-
- docs/ -- documentation (a bit empty for now)
-
-
-----------------------------------------------------------------------
-
-Glyph Image Formats:
-
- Drivers are now able to register new glyph image formats within the
- library. For now, the base layer supports of course bitmaps and
- vector outlines, but one could imagine something different like
- colored bitmaps, bi-color vectors or whatever else (Metafonts anyone
- ??).
-
- See the file `include/ftimage.h'. Note also that the type
- FT_Raster_Map is gone, and is now replaced by FT_Bitmap, which
- should encompass all known bitmap types.
-
- Each new image format must provide at least one `raster', i.e. a
- module capable of transforming the glyph image into a bitmap. It's
- also possible to change the default raster used for a given glyph
- image format.
-
- The default outline scan-converter now uses 128 levels of grays by
- default, which tends to smooth many things. Note that the demo
- programs have been updated significantly in order to display these..
-
-
-----------------------------------------------------------------------
-
-Build system:
-
- You still need GNU Make to build the library. The build system has
- been very seriously re-vamped in order to provide things like :
-
- - automatic host platform detection (reverting to 'config/ansi' if
- it is not detected, with pseudo-standard compilation flags)
-
- - the ability to compile from the Makefiles with very different and
- exotic compilers. Note that linking the library can be difficult
- for some platforms.
-
- For example, the file `config/win32/lcclib.bat' is invoked by the
- build system to create the `.lib' file with LCC-Win32 because its
- librarian has too many flaws to be invoked directly from the
- Makefile.
-
- Here's how it works:
-
- - the first time you type `make', the build system runs a series of
- sub-makefiles in order to detect your host platform. It then
- dumps what it found, and creates a file called `config.mk' in the
- current directory. This is a sub-Makefile used to define many
- important Make variables used to build the library.
-
- - the second time, the build system detects the `config.mk' then use
- it to build the library. All object files go into 'obj' by
- default, as well as the library file, but this can easily be
- changed.
-
- Note that you can run `make setup' to force another host platform
- detection even if a `config.mk' is present in the current
- directory. Another solution is simply to delete the file, then
- re-run make.
-
- Finally, the default compiler for all platforms is gcc (for now,
- this will hopefully changed in the future). You can however specify
- a different compiler by specifying it after the 'setup' target as
- in:
-
- gnumake setup lcc on Win32 to use the LCC compiler
- gnumake setup visualc on Win32 to use Visual C++
-
- See the file `config/<system>/detect.mk' for a list of supported
- compilers for your platforms.
-
- It should be relatively easy to write new detection rules files and
- config.mk..
-
- Finally, to build the demo programs, go to `demos' and launch GNU
- Make, it will use the `config.mk' in the top directory to build the
- test programs..
-
-
-----------------------------------------------------------------------
-
-Portability:
-
- In the previous beta, a single FT_System object was used to
- encompass all low-level operations like thread synchronisation,
- memory management and i/o access. This has been greatly simplified:
-
- - thread synchronisation has been dropped, for the simple reason
- that the library is already re-entrant, and that if you really
- need two threads accessing the same FT_Library, you should
- really synchronize access to it yourself with a simple mutex.
-
- - memory management is performed through a very simple object
- called `FT_Memory', which really is a table containing a table
- of pointers to functions like malloc, realloc and free as well
- as some user data (closure).
-
- - resources have disappeared (they created more problems than they
- solved), and i/o management have been simplified greatly as a
- result. Streams are defined through FT_Stream objects, which
- can be either memory-based or disk-based.
-
- Note that each face has its own stream, which is closed only
- when the face object is destroyed. Hence, a function like
- TT_Flush_Face in 1.x cannot be directly supported. However, if
- you really need something like this, you can easily tailor your
- own streams to achieve the same feature at a lower level (and
- use FT_Open_Face instead of FT_New_Face to create the face).
-
- See the file `include/ftsystem.h' for more details, as well as the
- implementations found in `config/unix' and `config/ansi'.
-
-
-----------------------------------------------------------------------
-
-Font Drivers:
-
- The Font Driver interface has been modified in order to support
- extensions & versioning.
-
-
- The list of the font drivers that are statically linked to the
- library at compile time is managed through a new configuration file
- called `config/<platform>/ftmodule.h'.
-
- This file is autogenerated when invoking `make modules'. This
- target will parse all sub-directories of 'src', looking for a
- `module.mk' rules file, used to describe the driver to the build
- system.
-
- Hence, one should call `make modules' each time a font driver is
- added or removed from the `src' directory.
-
- Finally, this version provides a `pseudo-driver' in `src/sfnt'.
- This driver doesn't support font files directly, but provides
- services used by all TrueType-like font drivers. Hence, its code is
- shared between the TrueType & OpenType font formats, and possibly
- more formats to come if we're lucky..
-
-
-----------------------------------------------------------------------
-
-Extensions support:
-
- The extensions support is inspired by the one found in 1.x.
-
- Now, each font driver has its own `extension registry', which lists
- which extensions are available for the font faces managed by the
- driver.
-
- Extension ids are now strings, rather than 4-byte tags, as this is
- usually more readable.
-
- Each extension has:
- - some data, associated to each face object
- - an interface (table of function pointers)
-
- An extension that is format-specific should simply register itself
- to the correct font driver. Here is some example code:
-
- // Registering an extensions
- //
- FT_Error FT_Init_XXXX_Extension( FT_Library library )
- {
- FT_DriverInterface* tt_driver;
-
- driver = FT_Get_Driver( library, "truetype" );
- if (!driver) return FT_Err_Unimplemented_Feature;
-
- return FT_Register_Extension( driver, &extension_class );
- }
-
-
- // Implementing the extensions
- //
- FT_Error FT_Proceed_Extension_XXX( FT_Face face )
- {
- FT_XXX_Extension ext;
- FT_XXX_Extension_Interface ext_interface;
-
- ext = FT_Get_Extension( face, "extensionid", &ext_interface );
- if (!ext) return error;
-
- return ext_interface->do_it(ext);
- }
-

-How to customize the compilation of the library
-===============================================
-
- FreeType is highly customizable to fit various needs, and this
- document describes how it is possible to select options and
- components at compilation time.
-
-
-I. Configuration macros
-
- The file `include/freetype/config/ftoption.h' contains a list of
- commented configuration macros that can be toggled by developers to
- indicate which features should be active while building the library.
-
- These options range from debug level to availability of certain
- features, like native TrueType hinting through a bytecode
- interpreter.
-
- We invite you to read this file for more information. You can
- change the file's content to suit your needs, or override it with
- one of the techniques described below.
-
-
-II. Modules list
-
- If you use GNU make please edit the top-level file `modules.cfg'.
- It contains a list of available FreeType modules and extensions to
- be compiled. Change it to suit your own preferences. Be aware that
- certain modules depend on others, as described in the file. GNU
- make uses `modules.cfg' to generate `ftmodule.h' (in the object
- directory).
-
- If you build FreeType in a directory separate from the source files,
- put your customized `modules.cfg' in that directory; that way you
- can keep the source files `clean'.
-
- If you don't use GNU make you have to manually edit the file
- `include/freetype/config/ftmodule.h' (which is *not* used with if
- compiled with GNU make) to add or remove the drivers and components
- you want to compile into the library. See `INSTALL.ANY' for more
- information.
-
-
-III. System interface
-
- FreeType's default interface to the system (i.e., the parts that
- deal with memory management and i/o streams) is located in
- `src/base/ftsystem.c'.
-
- The current implementation uses standard C library calls to manage
- memory and to read font files. It is however possible to write
- custom implementations to suit specific systems.
-
- To tell the GNU Make-based build system to use a custom system
- interface, you have to define the environment variable FTSYS_SRC to
- point to the relevant implementation:
-
- on Unix:
-
- ./configure <your options>
- export FTSYS_SRC=foo/my_ftsystem.c
- make
- make install
-
- on Windows:
-
- make setup <compiler>
- set FTSYS_SRC=foo/my_ftsystem.c
- make
-
-
-IV. Overriding default configuration and module headers
-
- It is possible to override the default configuration and module
- headers without changing the original files. There are three ways
- to do that:
-
-
- 1. With GNU make
-
- [This is actually a combination of method 2 and 3.]
-
- Just put your custom `ftoption.h' file into the objects directory
- (normally `<topdir>/objs' if you build in the source tree, or the
- directory where you invoke configure if you build in a separate
- directory), which GNU make prefers over the standard location. No
- action is needed for `ftmodule.h' because it is generated
- automatically in the objects directory.
-
- 2. Using the C include path
-
- Use the C include path to ensure that your own versions of the
- files are used at compile time when the lines
-
- #include FT_CONFIG_OPTIONS_H
- #include FT_CONFIG_MODULES_H
-
- are compiled. Their default values being
- <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, you
- can do something like:
-
- custom/
- config/
- ftoption.h => custom options header
- ftmodule.h => custom modules list
-
- include/ => normal FreeType 2 include
- ...
-
- then change the C include path to always give the path to `custom'
- before the FreeType 2 `include'.
-
-
- 3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H
-
- Another way to do the same thing is to redefine the macros used to
- name the configuration headers. To do so, you need a custom
- `ft2build.h' whose content can be as simple as:
-
- #ifndef FT2_BUILD_MY_PLATFORM_H_
- #define FT2_BUILD_MY_PLATFORM_H_
-
- #define FT_CONFIG_OPTIONS_H <custom/my-ftoption.h>

-Debugging within the FreeType sources
-=====================================
-
-I. Configuration macros
------------------------
-
-There are several ways to enable debugging features in a FreeType 2
-builds. This is controlled through the definition of special macros
-located in the file `ftoption.h'. The macros are:
-
-
- FT_DEBUG_LEVEL_ERROR
-
- #define this macro if you want to compile the FT_ERROR macro calls
- to print error messages during program execution. This will not
- stop the program. Very useful to spot invalid fonts during
- development and to code workarounds for them.
-
- FT_DEBUG_LEVEL_TRACE
-
- #define this macro if you want to compile both macros FT_ERROR and
- FT_TRACE. This also includes the variants FT_TRACE0, FT_TRACE1,
- FT_TRACE2, ..., FT_TRACE7.
-
- The trace macros are used to send debugging messages when an
- appropriate `debug level' is configured at runtime through the
- FT2_DEBUG environment variable (more on this later).
-
- FT_DEBUG_MEMORY
-
- If this macro is #defined, the FreeType engine is linked with a
- small but effective debugging memory manager that tracks all
- allocations and frees that are performed within the font engine.
-
- When the FT2_DEBUG_MEMORY environment variable is defined at
- runtime, a call to FT_Done_FreeType will dump memory statistics,
- including the list of leaked memory blocks with the source
- locations where these were allocated. It is always a very good
- idea to define this in development builds. This works with _any_
- program linked to FreeType, but requires a big deal of memory (the
- debugging memory manager never frees the blocks to the heap in
- order to detect double frees).
-
- When FT2_DEBUG_MEMORY isn't defined at runtime, the debugging
- memory manager is ignored, and performance is unaffected.
-
-
-II. Debugging macros
---------------------
-
-Several macros can be used within the FreeType sources to help
-debugging its code:
-
-
- 1. FT_ERROR(( ... ))
-
- This macro is used to send debug messages that indicate relatively
- serious errors (like broken font files), but will not stop the
- execution of the running program. Its code is compiled only when
- either FT_DEBUG_LEVEL_ERROR or FT_DEBUG_LEVEL_TRACE are defined in
- `ftoption.h'.
-
- Note that you have to use a printf-like signature, but with double
- parentheses, like in
-
- FT_ERROR(( "your %s is not %s\n", "foo", "bar" ));
-
-
- 2. FT_ASSERT( condition )
-
- This macro is used to check strong assertions at runtime. If its
- condition isn't TRUE, the program will abort with a panic message.
- Its code is compiled when either FT_DEBUG_LEVEL_ERROR or
- FT_DEBUG_LEVEL_TRACE are defined. You don't need double
- parentheses here. For example
-
- FT_ASSERT( ptr != NULL );
-
-
- 3. FT_TRACE( level, (message...) )
-
- The FT_TRACE macro is used to send general-purpose debugging
- messages during program execution. This macro uses an *implicit*
- macro named FT_COMPONENT used to name the current FreeType
- component being run.
-
- The developer should always define FT_COMPONENT as appropriate,
- for example as in
-
- #undef FT_COMPONENT
- #define FT_COMPONENT trace_io
-
- The value of the FT_COMPONENT macro is an enumeration named
- `trace_XXXX' where `XXXX' is one of the component names defined in
- the internal file `internal/fttrace.h'. If you modify FreeType
- source and insert new `trace_XXXX' macro, you must register it in
- `fttrace.h'. If you insert or remove many trace macros, you can
- check the undefined or the unused trace macro by
- `src/tools/chktrcmp.py'.
-
- Each such component is assigned a `debug level', ranging from 0 to
- 7, through the use of the FT2_DEBUG environment variable
- (described below) when a program linked with FreeType starts.
-
- When FT_TRACE is called, its level is compared to the one of the
- corresponding component. Messages with trace levels *higher* than
- the corresponding component level are filtered and never printed.
-
- This means that trace messages with level 0 are always printed,
- those with level 2 are only printed when the component level is
- *at least* 2.
-
- The second parameter to FT_TRACE must contain parentheses and
- correspond to a printf-like call, as in
-
- FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) )
-
- The shortcut macros FT_TRACE0, FT_TRACE1, FT_TRACE2, ...,
- FT_TRACE7 can be used with constant level indices, and are much
- cleaner to use, as in
-
- FT_TRACE2(( "your %s is not %s\n", "foo", "bar" ));
-
-
-III. Environment variables
---------------------------
-
-The following environment variables control debugging output and
-behaviour of FreeType at runtime.
-
-
- FT2_DEBUG
-
- This variable is only used when FreeType is built with
- FT_DEBUG_LEVEL_TRACE defined. It contains a list of component
- level definitions, following this format:
-
- component1:level1 component2:level2 component3:level3 ...
-
- where `componentX' is the name of a tracing component, as defined
- in `fttrace.h', but without the `trace_' prefix. `levelX' is the
- corresponding level to use at runtime.
-
- `any' is a special component name that will be interpreted as
- `any/all components'. For example, the following definitions
-
- set FT2_DEBUG=any:2 memory:5 io:4 (on Windows)
- export FT2_DEBUG="any:2 memory:5 io:4" (on Linux with bash)
-
- both stipulate that all components should have level 2, except for
- the memory and io components which will be set to trace levels 5
- and 4, respectively.
-
-
- FT2_DEBUG_MEMORY
-
- This environment variable, when defined, tells FreeType to use a
- debugging memory manager that will track leaking memory blocks as
- well as other common errors like double frees. It is also capable
- of reporting _where_ the leaking blocks were allocated, which
- considerably saves time when debugging new additions to the
- library.
-
- This code is only compiled when FreeType is built with the
- FT_DEBUG_MEMORY macro #defined in `ftoption.h' though, it will be
- ignored in other builds.
-
-
- FT2_ALLOC_TOTAL_MAX
-
- This variable is ignored if FT2_DEBUG_MEMORY is not defined. It
- allows you to specify a maximum heap size for all memory
- allocations performed by FreeType. This is very useful to test
- the robustness of the font engine and programs that use it in
- tight memory conditions.
-
- If it is undefined, or if its value is not strictly positive, then
- no allocation bounds are checked at runtime.
-
-
- FT2_ALLOC_COUNT_MAX
-
- This variable is ignored if FT2_DEBUG_MEMORY is not defined. It
- allows you to specify a maximum number of memory allocations
- performed by FreeType before returning the error
- FT_Err_Out_Of_Memory. This is useful for debugging and testing
- the engine's robustness.
-
- If it is undefined, or if its value is not strictly positive, then
- no allocation bounds are checked at runtime.

-Introduction
-============
-
- The FreeType Project is distributed in several archive packages;
- some of them may contain, in addition to the FreeType font engine,
- various tools and contributions which rely on, or relate to, the
- FreeType Project.
-
- This license applies to all files found in such packages, and
- which do not fall under their own explicit license. The license
- affects thus the FreeType font engine, the test programs,
- documentation and makefiles, at the very least.
-
- This license was inspired by the BSD, Artistic, and IJG
- (Independent JPEG Group) licenses, which all encourage inclusion
- and use of free software in commercial and freeware products
- alike. As a consequence, its main points are that:
-
- o We don't promise that this software works. However, we will be
- interested in any kind of bug reports. (`as is' distribution)
-
- o You can use this software for whatever you want, in parts or
- full form, without having to pay us. (`royalty-free' usage)
-
- o You may not pretend that you wrote this software. If you use
- it, or only parts of it, in a program, you must acknowledge
- somewhere in your documentation that you have used the
- FreeType code. (`credits')
-
- We specifically permit and encourage the inclusion of this
- software, with or without modifications, in commercial products.
- We disclaim all warranties covering The FreeType Project and
- assume no liability related to The FreeType Project.
-
-
- Finally, many people asked us for a preferred form for a
- credit/disclaimer to use in compliance with this license. We thus
- encourage you to use the following text:
-
- """
- Portions of this software are copyright © <year> The FreeType

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>

-There are several ways to build the FreeType library, depending on
-your system and the level of customization you need. Here is a short
-overview of the documentation available:
-
-
-I. Normal installation and upgrades
-===================================
-
- 1. Unix Systems (including Mac OS X, Cygwin, and MSys on Windows)
-
- Please read `INSTALL.UNIX' to install or upgrade FreeType 2 on a
- Unix system. Note that you *need* GNU Make for automatic
- compilation, since other make tools won't work (this includes BSD
- Make).
-
- GNU Make VERSION 3.80 OR NEWER IS NEEDED!
-
- [For `cmake' see below.]
-
-
- 2. On VMS with the `mms' build tool
-
- See `INSTALL.VMS' for installation instructions on this platform.
-
-
- 3. Other systems using GNU Make
-
- On non-Unix platforms, it is possible to build the library using
- GNU Make utility. Note that *NO OTHER MAKE TOOL WILL WORK*[1]!
- This methods supports several compilers on Windows, OS/2, and
- BeOS, including MinGW, Visual C++, Borland C++, and more.
-
- Instructions are provided in the file `INSTALL.GNU'.
-
-
- 4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior)
-
- We provide a small number of `project files' for various IDEs to
- automatically build the library as well. Note that these files
- are not supported and only sporadically maintained by FreeType
- developers, so don't expect them to work in each release.
-
- To find them, have a look at the content of the `builds/<system>'
- directory, where <system> stands for your OS or environment.
-
-
- 5. Using cmake
-
- See the top-level `CMakeLists.txt' file for more information.
-
-
- 6. From you own IDE, or own Makefiles
-
- If you want to create your own project file, follow the
- instructions given in the `INSTALL.ANY' document of this
- directory.
-
-
-II. Custom builds of the library
-================================
-
- Customizing the compilation of FreeType is easy, and allows you to
- select only the components of the font engine that you really need.
- For more details read the file `CUSTOMIZE'.
-
-
-----------------------------------------------------------------------
-
-[1] make++, a make tool written in Perl, has sufficient support of GNU
- make extensions to build FreeType. See
-
- http://makepp.sourceforge.net
-
- for more information; you need version 1.19 or newer, and you must
- pass option `--norc-substitution'.

-Instructions on how to build FreeType with your own build tool
-==============================================================
-
-See the file `CUSTOMIZE' to learn how to customize FreeType to
-specific environments.
-
-
-I. Standard procedure
----------------------
-
- * DISABLE PRE-COMPILED HEADERS! This is very important for Visual
- C++, because FreeType uses lines like:
-
- #include FT_FREETYPE_H
-
- which are not correctly supported by this compiler while being ISO
- C compliant!
-
- * You need to add the directory `include' to your include path when
- compiling the library.
-
- * FreeType 2 is made of several components; each of them is located
- in a subdirectory of `freetype2/src'. For example,
- `freetype2/src/truetype/' contains the TrueType font driver.
-
- * DO NOT COMPILE ALL C FILES! Rather, compile the following ones.
-
- -- base components (required)
-
- src/base/ftsystem.c
- src/base/ftinit.c
- src/base/ftdebug.c

-
-
- Notes:
-
- `ftcache.c' needs `ftglyph.c'
- `ftfstype.c' needs `fttype1.c'
- `ftglyph.c' needs `ftbitmap.c'
- `ftstroke.c' needs `ftglyph.c'
- `ftsynth.c' needs `ftbitmap.c'
-
- `cff.c' needs `sfnt.c', `pshinter.c', and `psnames.c'
- `truetype.c' needs `sfnt.c' and `psnames.c'
- `type1.c' needs `psaux.c' `pshinter.c', and `psnames.c'
- `type1cid.c' needs `psaux.c', `pshinter.c', and `psnames.c'
- `type42.c' needs `truetype.c'
-
- Please consult the central `include/freetype/config/ftoption.h'
- configuration file for details on additional libraries necessary
- for some optional features.
-
-
- Read the file `CUSTOMIZE' in case you want to compile only a subset
- of the drivers, renderers, and optional modules; a detailed
- description of the various base extension is given in the top-level
- file `modules.cfg'.
-
- You are done. In case of problems, see the archives of the FreeType
- development mailing list.
-
-
-II. Support for flat-directory compilation
-------------------------------------------
-
- It is possible to put all FreeType 2 source files into a single
- directory, with the *exception* of the `include' hierarchy.
-
- 1. Copy all files in current directory
-
- cp freetype2/src/base/*.[hc] .
- cp freetype2/src/raster1/*.[hc] .
- cp freetype2/src/smooth/*.[hc] .
- etc.
-
- 2. Compile sources
-
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
- cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
- etc.
-
- You don't need to define the FT_FLAT_COMPILATION macro (as this
- was required in previous releases of FreeType 2).

-This document contains instructions on how to cross-build the FreeType
-library on Unix systems, for example, building binaries for Linux/MIPS
-on FreeBSD/i386. Before reading this document, please consult the
-file `INSTALL.UNIX' for required tools and the basic self-building
-procedure.
-
-
- 1. Required Tools
- -----------------
-
- For self-building the FreeType library on a Unix system, GNU Make
- 3.80 or newer is required. `INSTALL.UNIX' contains hints how to
- check the installed `make'.
-
- The GNU C compiler to cross-build the target system is required.
- Currently, using a non-GNU cross compiler is untested. The cross
- compiler is expected to be installed with a system prefix. For
- example, if your building system is FreeBSD/i386 and the target
- system is Linux/MIPS, the cross compiler should be installed with
- the name `mips-ip22-linuxelf-gcc'.
-
- A C compiler for a self-build is required also, to build a tool
- (`apinames') that is executed during the build procedure. Non-GNU
- self compilers are acceptable, but such a setup is untested.
-
-
- 2. Configuration
- ----------------
-
- 2.1. Building and target system
-
- To configure a cross-build, the options `--host=<system>' and
- `--build=<system>' must be passed to the `configure' script.
- For example, if your build system is FreeBSD/i386 and the target
- system is Linux/MIPS, say
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- [other options]
-
- It should be noted that `--host=<system>' specifies the system
- where the built binaries will be executed, not the system where
- the build actually happens. Older versions of GNU autoconf use
- the option pair `--host=' and `--target='. This is broken and
- doesn't work. Similarly, an explicit CC specification like
-
- env CC=mips-ip22-linux-gcc ./configure # BAD
-
- or
-
- env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD
-
- doesn't work either; such a configuration confuses the
- `configure' script while trying to find the cross and native C
- compilers.
-
-
- 2.2. The prefix to install FreeType2
-
- Setting `--prefix=<prefix>' properly is important. The prefix
- to install FreeType2 is written into the `freetype-config'
- script and `freetype2.pc' configuration file.
-
- If the built FreeType 2 library is used as a part of the
- cross-building system, the prefix is expected to be different
- from the self-building system. For example, a configuration
- with `--prefix=/usr/local' installs binaries into the
- system-wide `/usr/local' directory, which then can't be executed
- due to the incorrect architecture. This causes confusion in
- configuration of all applications that use FreeType2. Instead,
- use a prefix to install the cross-build into a separate system
- tree, for example, `--prefix=/usr/local/mips-ip22-linux/'.
-
- On the other hand, if the built FreeType 2 library is used as a
- part of the target system, the prefix to install should reflect
- the file system structure of the target system.
-
-
- 2.3. Library dependencies
-
- FreeType normally depends on external libraries like `libpng' or
- `libharfbuzz'. The easiest case is to deactivate all such
- dependencies using the `--without-XXX' configuration options.
- However, if you want to use those libraries, you should ensure
- that they are available both on the target system and as
- (cross-compiled) libraries on the build system.
-
- FreeType uses `pkg-config' to find most of the libraries; the
- other libraries it links to are expected in the standard system
- directories. Since the default pkg-config's meta-information
- files (like `harfbuzz.pc') of the build platform don't work, use
- one of the two possible solutions below.
-
- o Use pkg-config's meta-information files that are adjusted to
- cross-compile and cross-link with the target platform's
- libraries. Make sure those files are found before the build
- system's default files. Example:
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
- [other options]
-
- See the manpage of `pkg-config' for more details.
-
- o Set variables like LIBPNG_LIBS as additional options to the
- `configure' script, overriding the values `pkg-config' would
- provide. `configure --help' shows the available environment
- variables. Example:
-
- ./configure \
- --build=i386-unknown-freebsd \
- --host=mips-ip22-linuxelf \
- LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
- LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
- [other options]
-
-
- 3. Building command
- -------------------
-
- If the configuration finishes successfully, invoking GNU make
- builds FreeType2. Just say
-
- make
-
- or
-
- gmake
-
- depending on the name the GNU make binary actually has.
-
-
- 4. Installation
- ---------------
-
- Saying
-
- make install
-
- as usual to install FreeType2 into the directory tree specified by
- the argument of the `--prefix' option.
-
- As noted in section 2.2, FreeType2 is sometimes configured to be
- installed into the system directory of the target system, and
- should not be installed in the cross-building system. In such
- cases, the make variable `DESTDIR' is useful to change the root
- directory in the installation. For example, after
-
- make DESTDIR=/mnt/target_system_root/ install
-
- the built FreeType2 library files are installed into the directory
- `/mnt/target_system_root/<prefix_in_configure>/lib'.
-
-
- 5. TODO
- -------
-
- Cross building between Cygwin (or MSys) and Unix must be tested.

-This document contains instructions how to build the FreeType library
-on non-Unix systems with the help of GNU Make. Note that if you are
-running Cygwin or MinGW/MSYS in Windows, you should follow the
-instructions in the file `INSTALL.UNIX' instead.
-
-
- FreeType 2 includes a powerful and flexible build system that allows
- you to easily compile it on a great variety of platforms from the
- command line. To do so, just follow these simple instructions.
-
- 1. Install GNU Make
- -------------------
-
- Because GNU Make is the only Make tool supported to compile
- FreeType 2, you should install it on your machine.
-
- The FreeType 2 build system relies on many features special to GNU
- Make.
-
- NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY
- INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
-
- Note that make++, a make tool written in Perl, supports enough
- features of GNU make to compile FreeType. See
-
- http://makepp.sourceforge.net
-
- for more information; you need version 1.19 or newer, and you must
- pass option `--norc-substitution'.
-
- Make sure that you are invoking GNU Make from the command line, by
- typing something like:
-
- make -v
-
- to display its version number.
-
- VERSION 3.80 OR NEWER IS NEEDED!
-
-
- 2. Invoke `make'
- ----------------
-
- Go to the root directory of FreeType 2, then simply invoke GNU
- Make from the command line. This will launch the FreeType 2 host
- platform detection routines. A summary will be displayed, for
- example, on Win32.
-
-
- ==============================================================
- FreeType build system -- automatic system detection
-
- The following settings are used:
-
- platform windows
- compiler gcc
- configuration directory .\builds\windows
- configuration rules .\builds\windows\w32-gcc.mk
-
- If this does not correspond to your system or settings please
- remove the file 'config.mk' from this directory then read the
- INSTALL file for help.
-
- Otherwise, simply type 'make' again to build the library
- or 'make refdoc' to build the API reference (the latter needs
- python).
- =============================================================
-
-
- If the detected settings correspond to your platform and compiler,
- skip to step 5. Note that if your platform is completely alien to
- the build system, the detected platform will be `ansi'.
-
-
- 3. Configure the build system for a different compiler
- ------------------------------------------------------
-
- If the build system correctly detected your platform, but you want
- to use a different compiler than the one specified in the summary
- (for most platforms, gcc is the default compiler), invoke GNU Make
- with
-
- make setup <compiler>
-
- Examples:
-
- to use Visual C++ on Win32, type: `make setup visualc'
- to use Borland C++ on Win32, type `make setup bcc32'
- to use Watcom C++ on Win32, type `make setup watcom'
- to use Intel C++ on Win32, type `make setup intelc'
- to use LCC-Win32 on Win32, type: `make setup lcc'
- to use Watcom C++ on OS/2, type `make setup watcom'
- to use VisualAge C++ on OS/2, type `make setup visualage'
-
- The <compiler> name to use is platform-dependent. The list of
- available compilers for your system is available in the file
- `builds/<system>/detect.mk'.
-
- If you are satisfied by the new configuration summary, skip to
- step 5.
-
-
- 4. Configure the build system for an unknown platform/compiler
- --------------------------------------------------------------
-
- The auto-detection/setup phase of the build system copies a file
- to the current directory under the name `config.mk'.
-
- For example, on OS/2+gcc, it would simply copy
- `builds/os2/os2-gcc.mk' to `./config.mk'.
-
- If for some reason your platform isn't correctly detected, copy
- manually the configuration sub-makefile to `./config.mk' and go to
- step 5.
-
- Note that this file is a sub-Makefile used to specify Make
- variables for compiler and linker invocation during the build.
- You can easily create your own version from one of the existing
- configuration files, then copy it to the current directory under
- the name `./config.mk'.
-
-
- 5. Build the library
- --------------------
-
- The auto-detection/setup phase should have copied a file in the
- current directory, called `./config.mk'. This file contains
- definitions of various Make variables used to invoke the compiler
- and linker during the build. [It has also generated a file called
- `ftmodule.h' in the objects directory (which is normally
- `<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for
- customization of FreeType.]
-
- To launch the build, simply invoke GNU Make again: The top
- Makefile will detect the configuration file and run the build with
- it.
-
-
- Final note
-
- The above instructions build a _statically_ linked library of the
- font engine in the `objs' directory. On Windows, you can build a
- DLL either with MinGW (within an MSYS shell, following the
- instructions in `INSTALL.UNIX'), or you use one of the Visual C++
- project files; see the subdirectories of `builds/windows'. For
- everything else, you are on your own, and you might follow the
- instructions in `INSTALL.ANY' to create your own Makefiles.

-
-Starting with Mac OS X 10.5, gcc defaults the deployment target to

-you want your built binaries to run only on 10.5, this change does not
-concern you. If you want them to also run on older versions of Mac
-OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET
-environment variable or pass `-mmacosx-version-min' to gcc. You
-should specify the oldest version of Mac OS you want the code to run
-on. For example, if you use Bourne shell:
-
- export MACOSX_DEPLOYMENT_TARGET=10.2
-
-or, if you use C shell:
-
- setenv MACOSX_DEPLOYMENT_TARGET 10.2
-
-Alternatively, you could pass `-mmacosx-version-min=10.2' to gcc.
-
-Here the number 10.2 is the lowest version that the built binaries can

-This document contains instructions on how to build the FreeType
-library on Unix systems. This also works for emulations like Cygwin
-or MSys on Win32:
-
-
- 1. Ensure that you are using GNU Make
- -------------------------------------
-
- The FreeType build system _exclusively_ works with GNU Make. You
- will not be able to compile the library with the instructions
- below using any other alternative (including BSD Make).
-
- Check that you have GNU make by running the command:
-
- make -v
-
- This should dump some text that begins with:
-
- GNU Make <version number>
- Copyright (C) <year> Free Software Foundation Inc.
-
- Note that version 3.80 or higher is *required* or the build will
- fail.
-
- It is also fine to have GNU Make under another name (e.g. 'gmake')
- if you use the MAKE variable as described below.
-
- As a special exception, 'makepp' can also be used to build
- FreeType 2. See the file docs/MAKEPP for details.
-
- For builds with `cmake' please check file `CMakeLists.txt'; this
- is a contributed file not directly supported by the FreeType team.
-
-
- 2. Regenerate the configure script if needed
- --------------------------------------------
-
- This only applies if you are building a git snapshot or checkout,
- *not* if you grabbed the sources of an official release.
-
- You need to invoke the `autogen.sh' script in the top-level
- directory in order to create the `configure' script for your
- platform. Normally, this simply means typing:
-
- sh autogen.sh
-
- In case of problems, you may need to install or upgrade Automake,
- Autoconf or Libtool. See README.git in the top-level directory
- for more information.
-
-
- 3. Build and install the library
- --------------------------------
-
- The following should work on all Unix systems where the `make'
- command invokes GNU Make:
-
- ./configure [options]
- make
- make install (as root)
-
- The default installation path is `/usr/local'. It can be changed
- with the `--prefix=<path>' option. Example:
-
- ./configure --prefix=/usr
-
- When using a different command to invoke GNU Make, use the MAKE
- variable. For example, if `gmake' is the command to use on your
- system, do something like:
-
- MAKE=gmake ./configure [options]
- gmake
- gmake install (as root)
-
- If this still doesn't work, there must be a problem with your
- system (e.g., you are using a very old version of GNU Make).
-
- It is possible to compile FreeType in a different directory.
- Assuming the FreeType source files in directory `/src/freetype' a
- compilation in directory `foo' works as follows:
-
- cd foo
- /src/freetype/configure [options]
- make
- make install
-
-
- 3.1 Interdependency with HarfBuzz
- .................................
-
- Note that there is a chicken-and-egg problem currently since the
- HarfBuzz library (used by the auto-hinter to improve support of
- OpenType fonts) depends on FreeType, which can be solved as
- follows in case HarfBuzz is not yet installed on your system.
-
- 1. Call FreeType's `configure' script with option
- `--without-harfbuzz', then compile and install FreeType.
-
- 2. Compile and install HarfBuzz.
-
- 3. Call FreeType's `configure' script without option
- `--without-harfbuzz' (after executing `make distclean'), then
- compile and install FreeType again.

-How to build the freetype2 library on VMS
------------------------------------------
-
-It is actually very straightforward to install the Freetype2 library.
-Just execute vms_make.com from the toplevel directory to build the
-library. This procedure currently accepts the following options:
-
-DEBUG
- Build the library with debug information and without optimization.
-
-lopts=<value>
- Options to pass to the link command e.g. lopts=/traceback
-
-ccopt=<value>
- Options to pass to the C compiler e.g. ccopt=/float=ieee
-
-In case you did download the demos, place them in a separate directory
-sharing the same toplevel as the directory of Freetype2 and follow the
-same instructions as above for the demos from there. The build
-process relies on this to figure the location of the Freetype2 include
-files.
-
-
-To rebuild the sources it is necessary to have MMS/MMK installed on
-the system.
-
-The library is available in the directory
-
- [.LIB]
-
-To compile applications using FreeType 2 you have to define the
-logical FREETYPE pointing to the directory
-
- [.INCLUDE.FREETYPE]
-
-i.e., if the directory in which this INSTALL.VMS file is located is
-$disk:[freetype] then define the logical with
-
- define freetype $disk:[freetype.include.freetype]
-
-This version has been tested with Compaq C V6.2-006 on OpenVMS Alpha
-V7.2-1.
-
-
- Any problems can be reported to
-
- Jouk Jansen <joukj@hrem.stm.tudelft.nl> or
- Martin P.J. Zinser <zinser@zinser.no-ip.info>

-The FreeType 2 font engine is copyrighted work and cannot be used
-legally without a software license. In order to make this project
-usable to a vast majority of developers, we distribute it under two
-mutually exclusive open-source licenses.
-
-This means that *you* must choose *one* of the two licenses described
-below, then obey all its terms and conditions when using FreeType 2 in
-any of your projects or products.
-
- - The FreeType License, found in the file `FTL.TXT', which is similar
- to the original BSD license *with* an advertising clause that forces
- you to explicitly cite the FreeType project in your product's
- documentation. All details are in the license file. This license
- is suited to products which don't use the GNU General Public
- License.
-
- Note that this license is compatible to the GNU General Public
- License version 3, but not version 2.
-
- - The GNU General Public License version 2, found in `GPLv2.TXT' (any
- later version can be used also), for programs which already use the
- GPL. Note that the FTL is incompatible with GPLv2 due to its
- advertisement clause.
-
-The contributed BDF and PCF drivers come with a license similar to that
-of the X Window System. It is compatible to the above two licenses (see
-file src/bdf/README and src/pcf/README). The same holds for the files
-`fthash.c' and `fthash.h'; their code was part of the BDF driver in
-earlier FreeType versions.
-
-The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
-compatible to the above two licenses.
-
-The MD5 checksum support (only used for debugging in development builds)
-is in the public domain.

-This file describes various problems that have been encountered in
-compiling, installing and running FreeType 2. Suggestions for
-additions or other improvements to this file are welcome.
-
-----------------------------------------------------------------------
-
-Running Problems
-================
-
-
-* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
- handled correctly.
-
------
-
-Of course, there might be bugs in FreeType, but some fonts based on
-the PostScript format can't be handled indeed. The reason is that
-FreeType doesn't contain a full PostScript interpreter but applies
-pattern matching instead. In case a font doesn't follow the standard
-structure of the given font format, FreeType fails. A typical example
-is Adobe's `Optima' font family which contains extra code to switch
-between low and high resolution versions of the glyphs.
-
-It might be possible to patch FreeType in some situations, though.
-Please report failing fonts so that we investigate the problem and set
-up a list of such problematic fonts.
-
-
-* Why do identical FreeType versions render differently on different
- platforms?
-
------
-
-Different distributions compile FreeType with different options. The
-developer version of a distribution's FreeType package, which is
-needed to compile your program against FreeType, includes the file
-ftoption.h. Compare each platform's copy of ftoption.h to find the
-differences.
-
-
-----------------------------------------------------------------------
-
-
-Compilation Problems
-====================
-
-
-* I get an `internal compilation error' (ICE) while compiling FreeType
- 2.2.1 with Intel C++.
-
- This has been reported for the following compiler version:
-
- Intel(R) C++ Compiler for 32-bit applications,
- Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
-
------
-
-The best solution is to update the compiler to version
-
- Intel(R) C++ Compiler for 32-bit applications,
- Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
-
-or newer. If this isn't feasible, apply the following patch.

-Due to our use of `libtool' to generate and install the FreeType 2
-libraries on Unix systems, as well as other historical events, it is
-generally very difficult to know precisely which release of the font
-engine is installed on a given system.
-
-This file tries to explain why and to document ways to properly detect
-FreeType on Unix.
-
-
-1. Version and Release numbers
-------------------------------
-
-For each new public release of FreeType 2, there are generally *three*
-distinct `version' numbers to consider:
-
- * The official FreeType 2 release number, like 2.3.1 or 2.4.10.
-
- * The libtool (and Unix) specific version number, like 13.0.7. This
- is what `freetype-config --version' returns.
-
- * The platform-specific shared object number, used for example when
- the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
-
-The platform-specific number is, unsurprisingly, platform-specific and
-varies with the operating system you are using (several variants of
-Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even
-for simple tests.
-
-The libtool-specific number does not equal the release number but is
-tied to it.
-
-The release number is available at *compile* time through the following
-macros defined in FT_FREETYPE_H:
-
- - FREETYPE_MAJOR: major release number
- - FREETYPE_MINOR: minor release number
- - FREETYPE_PATCH: patch release number
-
-See below for a small autoconf fragment.
-
-The release number is also available at *runtime* through the
-`FT_Library_Version' API.
-
-
-2. History
-----------
-
-The following table gives, for all releases since 2.4.0, the
-corresponding libtool number, as well as the shared object number found
-on _most_ systems, but not all of them:
-
-
- release libtool so

-3. Autoconf Code Fragment
--------------------------
-
-Lars Clausen contributed the following autoconf fragment to detect which
-version of FreeType is installed on a system. This one tests for a
-version that is at least 2.0.9; you should change it to check against
-other release numbers.

-This file contains a list of various font formats. It gives the
-reference document and whether it is supported in FreeType 2.
-
-Table fields
-------------
-
- wrapper format
- The format used to represent the font data. In the table below it
- is used only if the font format differs. Possible values are
-
- SFNT binary
- PFB binary
- PS a text header, followed by binary or text data
- LZW compressed with either `gzip' or `compress'
- BZ2 compressed with `bzip2'.
-
- font format
- How the font is to be accessed, possibly after converting the file
- type and wrapper format into a generic form. Bitmap formats are
- `BDF', `PCF', and one form of `WINFNT'; all others are vector
- formats. `PS' indicates third-order, `TT' second-order Bézier
- curves.
-
- font type
- Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
- formats, `MM' and `VAR' support optical axes. `CFF2' supports
- optical axes also.
-
- glyph access
- If not specified, the glyph access is `standard' to the font
- format. Values are `CID' for CID-keyed fonts, `SYNTHETIC' for
- fonts that are modified versions of other fonts by means of a
- transformation matrix, and `TYPE_0' for PS fonts which are to be
- accessed in a tree-like structure.
-
- FreeType driver
- The module in the FreeType library which handles the specific font
- format. A missing entry means that FreeType doesn't support the
- font format (yet).
-
-
-Notes
------
-
- The SFNT container format also provides `collections' (usually
- having the file extension `.ttc' or `.otc'). A collection contains
- multiple font faces that share some tables to avoid redundancy, thus
- reducing the file size. In FreeType, elements of a collection can
- be accessed with a proper face index.
-
- Both the GX and the OpenType 1.8 variation fonts provide `named
- instances'. FreeType maps them to face indices (they can also be
- accessed with the standard MM interface).
-
- Other font formats (not using the SFNT wrapper) also provide
- multiple faces within one file; they are marked with an asterisk
- (`*') in the table below.
-
- FreeType can be configured to support Mac files (on older Mac OS
- versions, a `file' is stored as a data and a resource fork, this is,
- within two separate data chunks). If a file can't be opened as a
- font, FreeType then checks whether it is a resource fork, trying to
- extract the contained font data from either a `POST' or `sfnt'
- resource.
-
-
-Please send additions and/or corrections to wl@gnu.org or to the
-FreeType developer's list at freetype-devel@nongnu.org (for
-subscribers only). If you can provide a font example for a format
-which isn't supported yet please send a mail too.

- How FreeType's rasterizer work
-
- by David Turner
-
- Revised 2007-Feb-01
-
-
-This file is an attempt to explain the internals of the FreeType
-rasterizer. The rasterizer is of quite general purpose and could
-easily be integrated into other programs.
-
-

-

- b. Decomposing Outlines into Profiles
- c. The Render Pool
- d. Computing Profiles Extents

- f. Sweeping and Sorting the Spans
-
-
-I. Introduction
-===============
-
- A rasterizer is a library in charge of converting a vectorial
- representation of a shape into a bitmap. The FreeType rasterizer
- has been originally developed to render the glyphs found in
- TrueType files, made up of segments and second-order Béziers.
- Meanwhile it has been extended to render third-order Bézier curves
- also. This document is an explanation of its design and
- implementation.
-
- While these explanations start from the basics, a knowledge of
- common rasterization techniques is assumed.
-
-
-II. Rendering Technology
-========================
-
-1. Requirements
----------------
-
- We assume that all scaling, rotating, hinting, etc., has been
- already done. The glyph is thus described by a list of points in
- the device space.
-
- - All point coordinates are in the 26.6 fixed float format. The
- used orientation is:
-
-
- ^ y
- | reference orientation
- |
- *----> x
- 0
-
-
- `26.6' means that 26 bits are used for the integer part of a
- value and 6 bits are used for the fractional part.
- Consequently, the `distance' between two neighbouring pixels is
- 64 `units' (1 unit = 1/64th of a pixel).
-
- Note that, for the rasterizer, pixel centers are located at
- integer coordinates. The TrueType bytecode interpreter,
- however, assumes that the lower left edge of a pixel (which is
- taken to be a square with a length of 1 unit) has integer
- coordinates.
-
-
- ^ y ^ y
- | |
- | (1,1) | (0.5,0.5)
- +-----------+ +-----+-----+
- | | | | |
- | | | | |
- | | | o-----+-----> x
- | | | (0,0) |
- | | | |
- o-----------+-----> x +-----------+
- (0,0) (-0.5,-0.5)
-
- TrueType bytecode interpreter FreeType rasterizer
-
-
- A pixel line in the target bitmap is called a `scanline'.
-
- - A glyph is usually made of several contours, also called
- `outlines'. A contour is simply a closed curve that delimits an
- outer or inner region of the glyph. It is described by a series
- of successive points of the points table.
-
- Each point of the glyph has an associated flag that indicates
- whether it is `on' or `off' the curve. Two successive `on'
- points indicate a line segment joining the two points.
-
- One `off' point amidst two `on' points indicates a second-degree
- (conic) Bézier parametric arc, defined by these three points
- (the `off' point being the control point, and the `on' ones the
- start and end points). Similarly, a third-degree (cubic) Bézier
- curve is described by four points (two `off' control points
- between two `on' points).
-
- Finally, for second-order curves only, two successive `off'
- points forces the rasterizer to create, during rendering, an
- `on' point amidst them, at their exact middle. This greatly
- facilitates the definition of successive Bézier arcs.
-
- The parametric form of a second-order Bézier curve is:
-
- P(t) = (1-t)^2*P1 + 2*t*(1-t)*P2 + t^2*P3
-
- (P1 and P3 are the end points, P2 the control point.)
-
- The parametric form of a third-order Bézier curve is:
-
- P(t) = (1-t)^3*P1 + 3*t*(1-t)^2*P2 + 3*t^2*(1-t)*P3 + t^3*P4
-
- (P1 and P4 are the end points, P2 and P3 the control points.)
-
- For both formulae, t is a real number in the range [0..1].
-
- Note that the rasterizer does not use these formulae directly.
- They exhibit, however, one very useful property of Bézier arcs:
- Each point of the curve is a weighted average of the control
- points.
-
- As all weights are positive and always sum up to 1, whatever the
- value of t, each arc point lies within the triangle (polygon)
- defined by the arc's three (four) control points.
-
- In the following, only second-order curves are discussed since
- rasterization of third-order curves is completely identical.
-
- Here some samples for second-order curves.
-
-

- * off curve

-
- *
- # __ Two `on' points with two `off'
- \ - - points between them. The point
- \ / \ marked `0' is the middle of the
- - 0 \ `off' points, and is a `virtual
- -_ _- # on' point where the curve passes.
- -- It does not appear in the point
- * list.
-
-
-2. Profiles and Spans
----------------------
-
- The following is a basic explanation of the _kind_ of computations
- made by the rasterizer to build a bitmap from a vector
- representation. Note that the actual implementation is slightly
- different, due to performance tuning and other factors.
-
- However, the following ideas remain in the same category, and are
- more convenient to understand.
-
-
- a. Sweeping the Shape
-
- The best way to fill a shape is to decompose it into a number of
- simple horizontal segments, then turn them on in the target
- bitmap. These segments are called `spans'.
-
- __---__
- _-- -_
- _- -
- - \
- / \
- / \
- | \
-
- __---__ Example: filling a shape
- _----------_ with spans.
- _--------------
- ----------------\
- /-----------------\ This is typically done from the top
- / \ to the bottom of the shape, in a
- | | \ movement called a `sweep'.
- V
-
- __---__
- _----------_
- _--------------
- ----------------\
- /-----------------\
- /-------------------\
- |---------------------\
-
-
- In order to draw a span, the rasterizer must compute its
- coordinates, which are simply the x coordinates of the shape's
- contours, taken on the y scanlines.
-
-
- /---/ |---| Note that there are usually
- /---/ |---| several spans per scanline.
- | /---/ |---|
- | /---/_______|---| When rendering this shape to the
- V /----------------| current scanline y, we must
- /-----------------| compute the x values of the
- a /----| |---| points a, b, c, and d.
- - - - * * - - - - * * - - y -
- / / b c| |d
-
-
- /---/ |---|
- /---/ |---| And then turn on the spans a-b
- /---/ |---| and c-d.
- /---/_______|---|
- /----------------|
- /-----------------|
- a /----| |---|
- - - - ####### - - - - ##### - - y -
- / / b c| |d
-
-
- b. Decomposing Outlines into Profiles
-
- For each scanline during the sweep, we need the following
- information:
-
- o The number of spans on the current scanline, given by the
- number of shape points intersecting the scanline (these are
- the points a, b, c, and d in the above example).
-
- o The x coordinates of these points.
-
- x coordinates are computed before the sweep, in a phase called
- `decomposition' which converts the glyph into *profiles*.
-
- Put it simply, a `profile' is a contour's portion that can only
- be either ascending or descending, i.e., it is monotonic in the
- vertical direction (we also say y-monotonic). There is no such
- thing as a horizontal profile, as we shall see.
-
- Here are a few examples:
-
-
- this square
- 1 2
- ---->---- is made of two
- | | | |
- | | profiles | |
- ^ v ^ + v
- | | | |
- | | | |
- ----<----
-
- up down
-
-
- this triangle
-
- P2 1 2
-
- |\ is made of two | \
- ^ | \ \ | \
- | | \ \ profiles | \ |
- | | \ v ^ | \ |
- | \ | | + \ v
- | \ | | \
- P1 ---___ \ ---___ \
- ---_\ ---_ \
- <--__ P3 up down
-
-
-
- A more general contour can be made of more than two profiles:
-
- __ ^
- / | / ___ / |
- / | / | / | / |
- | | / / => | v / /
- | | | | | | ^ |
- ^ | |___| | | ^ + | + | + v
- | | | v | |
- | | | up |
- |___________| | down |
-
- <-- up down
-
-
- Successive profiles are always joined by horizontal segments
- that are not part of the profiles themselves.
-
- For the rasterizer, a profile is simply an *array* that
- associates one horizontal *pixel* coordinate to each bitmap
- *scanline* crossed by the contour's section containing the
- profile. Note that profiles are *oriented* up or down along the
- glyph's original flow orientation.
-
- In other graphics libraries, profiles are also called `edges' or
- `edgelists'.
-
-
- c. The Render Pool
-
- FreeType has been designed to be able to run well on _very_
- light systems, including embedded systems with very few memory.
-
- A render pool will be allocated once; the rasterizer uses this
- pool for all its needs by managing this memory directly in it.
- The algorithms that are used for profile computation make it
- possible to use the pool as a simple growing heap. This means
- that this memory management is actually quite easy and faster
- than any kind of malloc()/free() combination.
-
- Moreover, we'll see later that the rasterizer is able, when
- dealing with profiles too large and numerous to lie all at once
- in the render pool, to immediately decompose recursively the
- rendering process into independent sub-tasks, each taking less
- memory to be performed (see `sub-banding' below).
-
- The render pool doesn't need to be large. A 4KByte pool is
- enough for nearly all renditions, though nearly 100% slower than
- a more comfortable 16KByte or 32KByte pool (that was tested with
- complex glyphs at sizes over 500 pixels).
-
-
- d. Computing Profiles Extents
-
- Remember that a profile is an array, associating a _scanline_ to
- the x pixel coordinate of its intersection with a contour.
-
- Though it's not exactly how the FreeType rasterizer works, it is
- convenient to think that we need a profile's height before
- allocating it in the pool and computing its coordinates.
-
- The profile's height is the number of scanlines crossed by the
- y-monotonic section of a contour. We thus need to compute these
- sections from the vectorial description. In order to do that,
- we are obliged to compute all (local and global) y extrema of
- the glyph (minima and maxima).
-
-
- P2 For instance, this triangle has only
- two y-extrema, which are simply
- |\
- | \ P2.y as a vertical maximum
- | \ P3.y as a vertical minimum
- | \
- | \ P1.y is not a vertical extremum (though
- | \ it is a horizontal minimum, which we
- P1 ---___ \ don't need).
- ---_\
- P3
-
-
- Note that the extrema are expressed in pixel units, not in
- scanlines. The triangle's height is certainly (P3.y-P2.y+1)
- pixel units, but its profiles' heights are computed in
- scanlines. The exact conversion is simple:
-
- - min scanline = FLOOR ( min y )
- - max scanline = CEILING( max y )
-
- A problem arises with Bézier Arcs. While a segment is always
- necessarily y-monotonic (i.e., flat, ascending, or descending),
- which makes extrema computations easy, the ascent of an arc can
- vary between its control points.
-
-
- P2
- *
- # on curve
- * off curve
- __-x--_
- _-- -_
- P1 _- - A non y-monotonic Bézier arc.
- # \
- - The arc goes from P1 to P3.
- \
- \ P3
- #
-
-
- We first need to be able to easily detect non-monotonic arcs,
- according to their control points. I will state here, without
- proof, that the monotony condition can be expressed as:
-
- P1.y <= P2.y <= P3.y for an ever-ascending arc
-
- P1.y >= P2.y >= P3.y for an ever-descending arc
-
- with the special case of
-
- P1.y = P2.y = P3.y where the arc is said to be `flat'.
-
- As you can see, these conditions can be very easily tested.
- They are, however, extremely important, as any arc that does not
- satisfy them necessarily contains an extremum.
-
- Note also that a monotonic arc can contain an extremum too,
- which is then one of its `on' points:
-
-
- P1 P2
- #---__ * P1P2P3 is ever-descending, but P1
- -_ is an y-extremum.
- -
- ---_ \
- -> \
- \ P3
- #
-
-
- Let's go back to our previous example:
-
-
- P2
- *
- # on curve
- * off curve
- __-x--_
- _-- -_
- P1 _- - A non-y-monotonic Bézier arc.
- # \
- - Here we have
- \ P2.y >= P1.y &&
- \ P3 P2.y >= P3.y (!)
- #
-
-
- We need to compute the vertical maximum of this arc to be able
- to compute a profile's height (the point marked by an `x'). The
- arc's equation indicates that a direct computation is possible,
- but we rely on a different technique, which use will become
- apparent soon.
-
- Bézier arcs have the special property of being very easily
- decomposed into two sub-arcs, which are themselves Bézier arcs.
- Moreover, it is easy to prove that there is at most one vertical
- extremum on each Bézier arc (for second-degree curves; similar
- conditions can be found for third-order arcs).
-
- For instance, the following arc P1P2P3 can be decomposed into
- two sub-arcs Q1Q2Q3 and R1R2R3:
-
-
- P2
- *
- # on curve
- * off curve
-
-
- original Bézier arc P1P2P3.
- __---__
- _-- --_
- _- -_
- - -
- / \
- / \
- # #
- P1 P3
-
-
-
- P2
- *
-
-
-
- Q3 Decomposed into two subarcs
- Q2 R2 Q1Q2Q3 and R1R2R3
- * __-#-__ *
- _-- --_
- _- R1 -_ Q1 = P1 R3 = P3
- - - Q2 = (P1+P2)/2 R2 = (P2+P3)/2
- / \
- / \ Q3 = R1 = (Q2+R2)/2
- # #
- Q1 R3 Note that Q2, R2, and Q3=R1
- are on a single line which is
- tangent to the curve.
-
-
- We have then decomposed a non-y-monotonic Bézier curve into two
- smaller sub-arcs. Note that in the above drawing, both sub-arcs
- are monotonic, and that the extremum is then Q3=R1. However, in
- a more general case, only one sub-arc is guaranteed to be
- monotonic. Getting back to our former example:
-
-
- Q2
- *
-
- __-x--_ R1
- _-- #_
- Q1 _- Q3 - R2
- # \ *
- -
- \
- \ R3
- #
-
-
- Here, we see that, though Q1Q2Q3 is still non-monotonic, R1R2R3
- is ever descending: We thus know that it doesn't contain the
- extremum. We can then re-subdivide Q1Q2Q3 into two sub-arcs and
- go on recursively, stopping when we encounter two monotonic
- subarcs, or when the subarcs become simply too small.
-
- We will finally find the vertical extremum. Note that the
- iterative process of finding an extremum is called `flattening'.
-
-
- e. Computing Profiles Coordinates
-
- Once we have the height of each profile, we are able to allocate
- it in the render pool. The next task is to compute coordinates
- for each scanline.
-
- In the case of segments, the computation is straightforward,
- using the Euclidean algorithm (also known as Bresenham).
- However, for Bézier arcs, the job is a little more complicated.
-
- We assume that all Béziers that are part of a profile are the
- result of flattening the curve, which means that they are all
- y-monotonic (ascending or descending, and never flat). We now
- have to compute the intersections of arcs with the profile's
- scanlines. One way is to use a similar scheme to flattening
- called `stepping'.
-
-
- Consider this arc, going from P1 to
- --------------------- P3. Suppose that we need to
- compute its intersections with the
- drawn scanlines. As already
- --------------------- mentioned this can be done
- directly, but the involved
- * P2 _---# P3 algorithm is far too slow.
- ------------- _-- --
- _-
- _/ Instead, it is still possible to
- ---------/----------- use the decomposition property in
- / the same recursive way, i.e.,
- | subdivide the arc into subarcs
- ------|-------------- until these get too small to cross
- | more than one scanline!
- |
- -----|--------------- This is very easily done using a
- | rasterizer-managed stack of
- | subarcs.
- # P1
-
-
- f. Sweeping and Sorting the Spans
-
- Once all our profiles have been computed, we begin the sweep to
- build (and fill) the spans.
-
- As both the TrueType and Type 1 specifications use the winding
- fill rule (but with opposite directions), we place, on each
- scanline, the present profiles in two separate lists.
-
- One list, called the `left' one, only contains ascending
- profiles, while the other `right' list contains the descending
- profiles.
-
- As each glyph is made of closed curves, a simple geometric
- property ensures that the two lists contain the same number of
- elements.
-
- Creating spans is thus straightforward:
-
- 1. We sort each list in increasing horizontal order.
-
- 2. We pair each value of the left list with its corresponding
- value in the right list.
-
-
- / / | | For example, we have here
- / / | | four profiles. Two of
- >/ / | | | them are ascending (1 &
- 1// / ^ | | | 2 3), while the two others
- // // 3| | | v are descending (2 & 4).
- / //4 | | | On the given scanline,
- a / /< | | the left list is (1,3),
- - - - *-----* - - - - *---* - - y - and the right one is
- / / b c| |d (4,2) (sorted).
-
- There are then two spans, joining
- 1 to 4 (i.e. a-b) and 3 to 2
- (i.e. c-d)!
-
-
- Sorting doesn't necessarily take much time, as in 99 cases out
- of 100, the lists' order is kept from one scanline to the next.
- We can thus implement it with two simple singly-linked lists,
- sorted by a classic bubble-sort, which takes a minimum amount of
- time when the lists are already sorted.
-
- A previous version of the rasterizer used more elaborate
- structures, like arrays to perform `faster' sorting. It turned
- out that this old scheme is not faster than the one described
- above.
-
- Once the spans have been `created', we can simply draw them in
- the target bitmap.

- and FREETYPE_PATCH.
-
-. Update version numbers in all files where necessary (for example, do
- a grep for both `2.3.1' and `231' for release 2.3.1).
-
-. builds/unix/configure.raw: Update `version_info'.
-
-. docs/CHANGES: Document differences to last release.
-
-. README: Update.
-
-. docs/VERSIONS.TXT: Document changed `version_info'.
-
-. ChangeLog: Announce new release (both in the freetype2 and
- freetype2-demos modules).
-
-. Clone the git archive to another directory with
-
- git clone -l -s . ../freetype2.test
-
- or something like this and run
-
- make distclean; make devel; make
- make distclean; make devel; make multi
- make distclean; make devel CC=g++; make CC=g++
- make distclean; make devel CC=g++; make multi CC=g++
-
- sh autogen.sh
- make distclean; ./configure; make
- make distclean; ./configure CC=g++; make
-
- in the cloned repository to test compilation with both gcc and g++.
-
-. Test C++ compilation for freetype2-demos too (using `git clone' as
- above).
-
-. Run src/tools/chktrcmp.py and check that there are no undefined
- trace_XXXX macros.
-
-. After pushing the new release, tag the git repositories (freetype2,
- freetype2-demos) with
-
- git tag VER-<version> -m "" -u <committer>
-
- and push the tags with
-
- git push --tags
-
-. Check with
-
- git clean -ndx
-
- that the git directory is really clean (and remove extraneous files
- if necessary).
-
-. Say `make dist' in both the freetype2 and freetype2-demos modules
- to generate the .tar.gz, .tar.bz2, and .zip files.
-
-. Create the doc bundles (freetype-doc-<version>.tar.gz,
- freetype-doc-<version>.tar.bz2, ftdoc<version>.zip). This is
- everything in
-
- <freetype-web git repository>/freetype2/docs
-
- except the `reference' subdirectory. Do *not* use option `-l' from
- zip!
-
-. Run the following script (with updated `$VERSION', `$SAVANNAH_USER',
- and $SOURCEFORGE_USER variables) to sign and upload the bundles to
- both Savannah and SourceForge. The signing code has been taken from
- the `gnupload' script (part of the automake bundle).

- /* */
- /* FT_FACE_FLAG_FIXED_SIZES :: */
- /* The face contains bitmap strikes. See also the */
- /* `num_fixed_sizes' and `available_sizes' fields of @FT_FaceRec. */
- /* */
- /* FT_FACE_FLAG_FIXED_WIDTH :: */
- /* The face contains fixed-width characters (like Courier, Lucida, */
- /* MonoType, etc.). */
- /* */
- /* FT_FACE_FLAG_SFNT :: */
- /* The face uses the SFNT storage scheme. For now, this means */
- /* TrueType and OpenType. */
- /* */
- /* FT_FACE_FLAG_HORIZONTAL :: */
- /* The face contains horizontal glyph metrics. This should be set */
- /* for all common formats. */
- /* */
- /* FT_FACE_FLAG_VERTICAL :: */
- /* The face contains vertical glyph metrics. This is only */
- /* available in some formats, not all of them. */
- /* */
- /* FT_FACE_FLAG_KERNING :: */
- /* The face contains kerning information. If set, the kerning */
- /* distance can be retrieved using the function @FT_Get_Kerning. */
- /* Otherwise the function always return the vector (0,0). Note */
- /* that FreeType doesn't handle kerning data from the SFNT `GPOS' */
- /* table (as present in many OpenType fonts). */
- /* */
- /* FT_FACE_FLAG_FAST_GLYPHS :: */
- /* THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. */
- /* */
- /* FT_FACE_FLAG_MULTIPLE_MASTERS :: */
- /* The face contains multiple masters and is capable of */
- /* interpolating between them. Supported formats are Adobe MM, */
- /* TrueType GX, and OpenType variation fonts. */
- /* */
- /* See the multiple-masters specific API for details. */
- /* */
- /* FT_FACE_FLAG_GLYPH_NAMES :: */
- /* The face contains glyph names, which can be retrieved using */

- /* broken glyph name tables. Use the function */
- /* @FT_Has_PS_Glyph_Names when needed. */
- /* */
- /* FT_FACE_FLAG_EXTERNAL_STREAM :: */
- /* Used internally by FreeType to indicate that a face's stream was */
- /* provided by the client application and should not be destroyed */
- /* when @FT_Done_Face is called. Don't read or test this flag. */
- /* */
- /* FT_FACE_FLAG_HINTER :: */
- /* The font driver has a hinting machine of its own. For example, */
- /* with TrueType fonts, it makes sense to use data from the SFNT */
- /* `gasp' table only if the native TrueType hinting engine (with */
- /* the bytecode interpreter) is available and active. */
- /* */
- /* FT_FACE_FLAG_CID_KEYED :: */
- /* The face is CID-keyed. In that case, the face is not accessed */
- /* by glyph indices but by CID values. For subsetted CID-keyed */
- /* fonts this has the consequence that not all index values are a */
- /* valid argument to @FT_Load_Glyph. Only the CID values for which */
- /* corresponding glyphs in the subsetted font exist make */
- /* `FT_Load_Glyph' return successfully; in all other cases you get */
- /* an `FT_Err_Invalid_Argument' error. */
- /* */
- /* Note that CID-keyed fonts that are in an SFNT wrapper (this is, */
- /* all OpenType/CFF fonts) don't have this flag set since the */
- /* glyphs are accessed in the normal way (using contiguous */
- /* indices); the `CID-ness' isn't visible to the application. */
- /* */
- /* FT_FACE_FLAG_TRICKY :: */
- /* The face is `tricky', this is, it always needs the font format's */
- /* native hinting engine to get a reasonable result. A typical */
- /* example is the old Chinese font `mingli.ttf' (but not */
- /* `mingliu.ttc') that uses TrueType bytecode instructions to move */
- /* and scale all of its subglyphs. */
- /* */
- /* It is not possible to auto-hint such fonts using */
- /* @FT_LOAD_FORCE_AUTOHINT; it will also ignore */
- /* @FT_LOAD_NO_HINTING. You have to set both @FT_LOAD_NO_HINTING */
- /* and @FT_LOAD_NO_AUTOHINT to really disable hinting; however, you */
- /* probably never want this except for demonstration purposes. */
- /* */
- /* Currently, there are about a dozen TrueType fonts in the list of */
- /* tricky fonts; they are hard-coded in file `ttobjs.c'. */

- *
- * @enum:
- * FT_LOAD_XXX
- *
- * @description:
- * A list of bit field constants for @FT_Load_Glyph to indicate what
- * kind of operations to perform during glyph loading.
- *
- * @values:
- * FT_LOAD_DEFAULT ::
- * Corresponding to~0, this value is used as the default glyph load
- * operation. In this case, the following happens:
- *
- * 1. FreeType looks for a bitmap for the glyph corresponding to the
- * face's current size. If one is found, the function returns.
- * The bitmap data can be accessed from the glyph slot (see note
- * below).
- *
- * 2. If no embedded bitmap is searched for or found, FreeType looks
- * for a scalable outline. If one is found, it is loaded from
- * the font file, scaled to device pixels, then `hinted' to the
- * pixel grid in order to optimize it. The outline data can be
- * accessed from the glyph slot (see note below).
- *
- * Note that by default the glyph loader doesn't render outlines into
- * bitmaps. The following flags are used to modify this default
- * behaviour to more specific and useful cases.
- *
- * FT_LOAD_NO_SCALE ::
- * Don't scale the loaded outline glyph but keep it in font units.
- *
- * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
- * unsets @FT_LOAD_RENDER.
- *
- * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
- * FT_LOAD_NO_SCALE usually yields meaningless outlines because the
- * subglyphs must be scaled and positioned with hinting instructions.
- * This can be solved by loading the font without FT_LOAD_NO_SCALE and
- * setting the character size to `font->units_per_EM'.
- *
- * FT_LOAD_NO_HINTING ::
- * Disable hinting. This generally generates `blurrier' bitmap glyphs
- * when the glyph are rendered in any of the anti-aliased modes. See
- * also the note below.
- *
- * This flag is implied by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_RENDER ::
- * Call @FT_Render_Glyph after the glyph is loaded. By default, the
- * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
- * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
- *
- * This flag is unset by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_NO_BITMAP ::
- * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
- * flag.
- *
- * @FT_LOAD_NO_SCALE always sets this flag.
- *
- * FT_LOAD_VERTICAL_LAYOUT ::
- * Load the glyph for vertical text layout. In particular, the
- * `advance' value in the @FT_GlyphSlotRec structure is set to the
- * `vertAdvance' value of the `metrics' field.
- *
- * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
- * this flag currently. Reason is that in this case vertical metrics
- * get synthesized, and those values are not always consistent across
- * various font formats.
- *
- * FT_LOAD_FORCE_AUTOHINT ::
- * Prefer the auto-hinter over the font's native hinter. See also
- * the note below.
- *
- * FT_LOAD_PEDANTIC ::
- * Make the font driver perform pedantic verifications during glyph
- * loading. This is mostly used to detect broken glyphs in fonts.
- * By default, FreeType tries to handle broken fonts also.
- *
- * In particular, errors from the TrueType bytecode engine are not
- * passed to the application if this flag is not set; this might
- * result in partially hinted or distorted glyphs in case a glyph's
- * bytecode is buggy.
- *
- * FT_LOAD_NO_RECURSE ::
- * Don't load composite glyphs recursively. Instead, the font
- * driver should set the `num_subglyph' and `subglyphs' values of
- * the glyph slot accordingly, and set `glyph->format' to
- * @FT_GLYPH_FORMAT_COMPOSITE. The description of subglyphs can
- * then be accessed with @FT_Get_SubGlyph_Info.
- *
- * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
- *
- * FT_LOAD_IGNORE_TRANSFORM ::
- * Ignore the transform matrix set by @FT_Set_Transform.
- *
- * FT_LOAD_MONOCHROME ::
- * This flag is used with @FT_LOAD_RENDER to indicate that you want to
- * render an outline glyph to a 1-bit monochrome bitmap glyph, with
- * 8~pixels packed into each byte of the bitmap data.
- *
- * Note that this has no effect on the hinting algorithm used. You
- * should rather use @FT_LOAD_TARGET_MONO so that the
- * monochrome-optimized hinting algorithm is used.
- *
- * FT_LOAD_LINEAR_DESIGN ::
- * Keep `linearHoriAdvance' and `linearVertAdvance' fields of
- * @FT_GlyphSlotRec in font units. See @FT_GlyphSlotRec for
- * details.
- *
- * FT_LOAD_NO_AUTOHINT ::
- * Disable the auto-hinter. See also the note below.
- *
- * FT_LOAD_COLOR ::
- * Load embedded color bitmap images. The resulting color bitmaps,
- * if available, will have the @FT_PIXEL_MODE_BGRA format. If the
- * flag is not set and color bitmaps are found, they are converted
- * to 256-level gray bitmaps transparently, using the
- * @FT_PIXEL_MODE_GRAY format.
- *
- * FT_LOAD_COMPUTE_METRICS ::
- * Compute glyph metrics from the glyph data, without the use of
- * bundled metrics tables (for example, the `hdmx' table in TrueType
- * fonts). This flag is mainly used by font validating or font
- * editing applications, which need to ignore, verify, or edit those
- * tables.
- *
- * Currently, this flag is only implemented for TrueType fonts.
- *
- * FT_LOAD_BITMAP_METRICS_ONLY ::
- * Request loading of the metrics and bitmap image information of a
- * (possibly embedded) bitmap glyph without allocating or copying
- * the bitmap image data itself. No effect if the target glyph is
- * not a bitmap image.
- *
- * This flag unsets @FT_LOAD_RENDER.
- *
- * FT_LOAD_CROP_BITMAP ::
- * Ignored. Deprecated.
- *
- * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
- * Ignored. Deprecated.
- *
- * @note:
- * By default, hinting is enabled and the font's native hinter (see
- * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
- * disable hinting by setting @FT_LOAD_NO_HINTING or change the
- * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
- * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
- * used at all.
- *
- * See the description of @FT_FACE_FLAG_TRICKY for a special exception
- * (affecting only a handful of Asian fonts).
- *
- * Besides deciding which hinter to use, you can also decide which
- * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
- *
- * Note that the auto-hinter needs a valid Unicode cmap (either a native
- * one or synthesized by FreeType) for producing correct results. If a
- * font provides an incorrect mapping (for example, assigning the
- * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
- * mathematical integral sign), the auto-hinter might produce useless
- * results.

- *
- * @enum:
- * FT_LOAD_TARGET_XXX
- *
- * @description:
- * A list of values to select a specific hinting algorithm for the
- * hinter. You should OR one of these values to your `load_flags'
- * when calling @FT_Load_Glyph.
- *
- * Note that a font's native hinters may ignore the hinting algorithm
- * you have specified (e.g., the TrueType bytecode interpreter). You
- * can set @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is
- * used.
- *
- * @values:
- * FT_LOAD_TARGET_NORMAL ::
- * The default hinting algorithm, optimized for standard gray-level
- * rendering. For monochrome output, use @FT_LOAD_TARGET_MONO
- * instead.
- *
- * FT_LOAD_TARGET_LIGHT ::
- * A lighter hinting algorithm for gray-level modes. Many generated
- * glyphs are fuzzier but better resemble their original shape. This
- * is achieved by snapping glyphs to the pixel grid only vertically
- * (Y-axis), as is done by FreeType's new CFF engine or Microsoft's
- * ClearType font renderer. This preserves inter-glyph spacing in
- * horizontal text. The snapping is done either by the native font
- * driver, if the driver itself and the font support it, or by the
- * auto-hinter.
- *
- * Advance widths are rounded to integer values; however, using the
- * `lsb_delta' and `rsb_delta' fields of @FT_GlyphSlotRec, it is
- * possible to get fractional advance widths for sub-pixel positioning
- * (which is recommended to use).
- *
- * If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active,
- * TrueType-like metrics are used to make this mode behave similarly
- * as in unpatched FreeType versions between 2.4.6 and 2.7.1
- * (inclusive).
- *
- * FT_LOAD_TARGET_MONO ::
- * Strong hinting algorithm that should only be used for monochrome
- * output. The result is probably unpleasant if the glyph is rendered
- * in non-monochrome modes.
- *
- * FT_LOAD_TARGET_LCD ::
- * A variant of @FT_LOAD_TARGET_LIGHT optimized for horizontally
- * decimated LCD displays.
- *
- * FT_LOAD_TARGET_LCD_V ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
- * decimated LCD displays.
- *
- * @note:
- * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
- * `load_flags'. They can't be ORed.
- *
- * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
- * corresponding mode (i.e., the mode that matches the used algorithm
- * best). An exception is FT_LOAD_TARGET_MONO since it implies
- * @FT_LOAD_MONOCHROME.
- *
- * You can use a hinting algorithm that doesn't correspond to the same
- * rendering mode. As an example, it is possible to use the `light'
- * hinting algorithm and have the results rendered in horizontal LCD
- * pixel mode, with code like
- *
- * {
- * FT_Load_Glyph( face, glyph_index,
- * load_flags | FT_LOAD_TARGET_LIGHT );
- *
- * FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );
- * }
- *
- * In general, you should stick with one rendering mode. For example,
- * switching between @FT_LOAD_TARGET_NORMAL and @FT_LOAD_TARGET_MONO
- * enforces a lot of recomputation for TrueType fonts, which is slow.
- * Another reason is caching: Selecting a different mode usually causes
- * changes in both the outlines and the rasterized bitmaps; it is thus
- * necessary to empty the cache after a mode switch to avoid false hits.

- /* */
- /* <Description> */
- /* Many characters, especially for CJK scripts, have variant forms. */
- /* They are a sort of grey area somewhere between being totally */
- /* irrelevant and semantically distinct; for this reason, the Unicode */
- /* consortium decided to introduce Variation Sequences (VS), */
- /* consisting of a Unicode base character and a variation selector */
- /* instead of further extending the already huge number of */
- /* characters. */
- /* */
- /* Unicode maintains two different sets, namely `Standardized */
- /* Variation Sequences' and registered `Ideographic Variation */
- /* Sequences' (IVS), collected in the `Ideographic Variation */
- /* Database' (IVD). */
- /* */
- /* http://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt */
- /* http://unicode.org/reports/tr37/ */
- /* http://unicode.org/ivd/ */
- /* */
- /* To date (January 2017), the character with the most ideographic */
- /* variations is U+9089, having 32 such IVS. */
- /* */
- /* Three Mongolian Variation Selectors have the values U+180B-U+180D; */
- /* 256 generic Variation Selectors are encoded in the ranges */
- /* U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation */
- /* Selectors from the range U+E0100-U+E01EF only. */
- /* */
- /* A VS consists of the base character value followed by a single */
- /* Variation Selector. For example, to get the first variation of */
- /* U+9089, you have to write the character sequence `U+9089 U+E0100'. */
- /* */
- /* Adobe and MS decided to support both standardized and ideographic */
- /* VS with a new cmap subtable (format~14). It is an odd subtable */
- /* because it is not a mapping of input code points to glyphs, but */
- /* contains lists of all variations supported by the font. */
- /* */
- /* A variation may be either `default' or `non-default' for a given */
- /* font. A default variation is the one you will get for that code */
- /* point if you look it up in the standard Unicode cmap. A */

- * glyph-to-script-map
- *
- * @description:
- * *Experimental* *only*
- *
- * The auto-hinter provides various script modules to hint glyphs.
- * Examples of supported scripts are Latin or CJK. Before a glyph is
- * auto-hinted, the Unicode character map of the font gets examined, and
- * the script is then determined based on Unicode character ranges, see
- * below.
- *
- * OpenType fonts, however, often provide much more glyphs than
- * character codes (small caps, superscripts, ligatures, swashes, etc.),
- * to be controlled by so-called `features'. Handling OpenType features
- * can be quite complicated and thus needs a separate library on top of
- * FreeType.
- *
- * The mapping between glyph indices and scripts (in the auto-hinter
- * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
- * array with `num_glyphs' elements, as found in the font's @FT_Face
- * structure. The `glyph-to-script-map' property returns a pointer to
- * this array, which can be modified as needed. Note that the
- * modification should happen before the first glyph gets processed by
- * the auto-hinter so that the global analysis of the font shapes
- * actually uses the modified mapping.
- *
- * The following example code demonstrates how to access it (omitting
- * the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_Prop_GlyphToScriptMap prop;
- *
- *
- * FT_Init_FreeType( &library );
- * FT_New_Face( library, "foo.ttf", 0, &face );
- *
- * prop.face = face;
- *
- * FT_Property_Get( library, "autofitter",
- * "glyph-to-script-map", &prop );
- *
- * // adjust `prop.map' as needed right here

- * @description:
- * *Experimental* *only*, *requires* *linear* *alpha* *blending* *and*
- * *gamma* *correction*
- *
- * Stem darkening emboldens glyphs at smaller sizes to make them more
- * readable on common low-DPI screens when using linear alpha blending
- * and gamma correction, see @FT_Render_Glyph. When not using linear
- * alpha blending and gamma correction, glyphs will appear heavy and
- * fuzzy!
- *
- * Gamma correction essentially lightens fonts since shades of grey are
- * shifted to higher pixel values (=~higher brightness) to match the
- * original intention to the reality of our screens. The side-effect is
- * that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
- * rendering library implement a counter-measure: stem darkening at
- * smaller sizes where shades of gray dominate. By emboldening a glyph
- * slightly in relation to its pixel size, individual pixels get higher
- * coverage of filled-in outlines and are therefore `blacker'. This
- * counteracts the `thinning out' of glyphs, making text remain readable
- * at smaller sizes. All glyphs that pass through the auto-hinter will
- * be emboldened unless this property is set to TRUE.
- *
- * See the description of the CFF driver for algorithmic details. Total
- * consistency with the CFF driver is currently not achieved because the
- * emboldening method differs and glyphs must be scaled down on the
- * Y-axis to keep outline points inside their precomputed blue zones.
- * The smaller the size (especially 9ppem and down), the higher the loss
- * of emboldening versus the CFF driver.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment

- *
- * <Title>
- * Cache Sub-System
- *
- * <Abstract>
- * How to cache face, size, and glyph data with FreeType~2.
- *
- * <Description>
- * This section describes the FreeType~2 cache sub-system, which is used
- * to limit the number of concurrently opened @FT_Face and @FT_Size
- * objects, as well as caching information like character maps and glyph
- * images while limiting their maximum memory usage.
- *
- * Note that all types and functions begin with the `FTC_' prefix.
- *
- * The cache is highly portable and thus doesn't know anything about the
- * fonts installed on your system, or how to access them. This implies
- * the following scheme:
- *
- * First, available or installed font faces are uniquely identified by
- * @FTC_FaceID values, provided to the cache by the client. Note that
- * the cache only stores and compares these values, and doesn't try to
- * interpret them in any way.
- *
- * Second, the cache calls, only when needed, a client-provided function
- * to convert an @FTC_FaceID into a new @FT_Face object. The latter is
- * then completely managed by the cache, including its termination
- * through @FT_Done_Face. To monitor termination of face objects, the
- * finalizer callback in the `generic' field of the @FT_Face object can
- * be used, which might also be used to store the @FTC_FaceID of the
- * face.
- *
- * Clients are free to map face IDs to anything else. The most simple
- * usage is to associate them to a (pathname,face_index) pair that is
- * used to call @FT_New_Face. However, more complex schemes are also
- * possible.
- *
- * Note that for the cache to work correctly, the face ID values must be
- * *persistent*, which means that the contents they point to should not
- * change at runtime, or that their value should not become invalid.
- *
- * If this is unavoidable (e.g., when a font is uninstalled at runtime),
- * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
- * the cache get rid of any references to the old @FTC_FaceID it may
- * keep internally. Failure to do so will lead to incorrect behaviour
- * or even crashes.
- *
- * To use the cache, start with calling @FTC_Manager_New to create a new
- * @FTC_Manager object, which models a single cache instance. You can
- * then look up @FT_Face and @FT_Size objects with
- * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
- *
- * If you want to use the charmap caching, call @FTC_CMapCache_New, then
- * later use @FTC_CMapCache_Lookup to perform the equivalent of
- * @FT_Get_Char_Index, only much faster.
- *
- * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
- * later use @FTC_ImageCache_Lookup to retrieve the corresponding
- * @FT_Glyph objects from the cache.
- *
- * If you need lots of small bitmaps, it is much more memory efficient
- * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
- * returns @FTC_SBitRec structures, which are used to store small
- * bitmaps directly. (A small bitmap is one whose metrics and
- * dimensions all fit into 8-bit integers).
- *
- * We hope to also provide a kerning cache in the near future.

- * @section:
- * cff_driver
- *
- * @title:
- * The CFF driver
- *
- * @abstract:
- * Controlling the CFF driver module.
- *
- * @description:
- * While FreeType's CFF driver doesn't expose API functions by itself,
- * it is possible to control its behaviour with @FT_Property_Set and
- * @FT_Property_Get. The list below gives the available properties
- * together with the necessary macros and structures.
- *
- * The CFF driver's module name is `cff'.
- *
- * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
- *
- * The rasterizer is positioning horizontal features (e.g., ascender
- * height & x-height, or crossbars) on the pixel grid and minimizing the
- * amount of antialiasing applied to them, while placing vertical
- * features (vertical stems) on the pixel grid without hinting, thus
- * representing the stem position and weight accurately. Sometimes the
- * vertical stems may be only partially black. In this context,
- * `antialiasing' means that stems are not positioned exactly on pixel
- * borders, causing a fuzzy appearance.
- *
- * There are two principles behind this approach.
- *
- * 1) No hinting in the horizontal direction: Unlike `superhinted'
- * TrueType, which changes glyph widths to accommodate regular
- * inter-glyph spacing, Adobe's approach is `faithful to the design' in
- * representing both the glyph width and the inter-glyph spacing
- * designed for the font. This makes the screen display as close as it
- * can be to the result one would get with infinite resolution, while
- * preserving what is considered the key characteristics of each glyph.
- * Note that the distances between unhinted and grid-fitted positions at
- * small sizes are comparable to kerning values and thus would be
- * noticeable (and distracting) while reading if hinting were applied.
- *
- * One of the reasons to not hint horizontally is antialiasing for LCD
- * screens: The pixel geometry of modern displays supplies three
- * vertical sub-pixels as the eye moves horizontally across each visible
- * pixel. On devices where we can be certain this characteristic is
- * present a rasterizer can take advantage of the sub-pixels to add
- * increments of weight. In Western writing systems this turns out to
- * be the more critical direction anyway; the weights and spacing of
- * vertical stems (see above) are central to Armenian, Cyrillic, Greek,
- * and Latin type designs. Even when the rasterizer uses greyscale
- * antialiasing instead of color (a necessary compromise when one
- * doesn't know the screen characteristics), the unhinted vertical
- * features preserve the design's weight and spacing much better than
- * aliased type would.
- *
- * 2) Alignment in the vertical direction: Weights and spacing along the
- * y~axis are less critical; what is much more important is the visual
- * alignment of related features (like cap-height and x-height). The
- * sense of alignment for these is enhanced by the sharpness of grid-fit
- * edges, while the cruder vertical resolution (full pixels instead of
- * 1/3 pixels) is less of a problem.
- *
- * On the technical side, horizontal alignment zones for ascender,
- * x-height, and other important height values (traditionally called
- * `blue zones') as defined in the font are positioned independently,
- * each being rounded to the nearest pixel edge, taking care of
- * overshoot suppression at small sizes, stem darkening, and scaling.
- *
- * Hstems (this is, hint values defined in the font to help align
- * horizontal features) that fall within a blue zone are said to be
- * `captured' and are aligned to that zone. Uncaptured stems are moved
- * in one of four ways, top edge up or down, bottom edge up or down.
- * Unless there are conflicting hstems, the smallest movement is taken
- * to minimize distortion.

- * @description:
- * By default, the Adobe CFF engine darkens stems as follows (if the

- *
- * {
- * stem width <= 0.5px: darkening amount = 0.4px
- * stem width = 1px: darkening amount = 0.275px
- * stem width = 1.667px: darkening amount = 0.275px
- * stem width >= 2.333px: darkening amount = 0px
- * }
- *
- * and piecewise linear in-between. At configuration time, these four
- * control points can be set with the macro
- * `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'. At runtime, the control
- * points can be changed using the `darkening-parameters' property, as
- * the following example demonstrates.
- *
- * {
- * FT_Library library;
- * FT_Int darken_params[8] = { 500, 300, // x1, y1
- * 1000, 200, // x2, y2

- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "cff",
- * "darkening-parameters", darken_params );
- * }
- *
- * The x~values give the stem width, and the y~values the darkening
- * amount. The unit is 1000th of pixels. All coordinate values must be
- * positive; the x~values must be monotonically increasing; the
- * y~values must be monotonically decreasing and smaller than or
- * equal to 500 (corresponding to half a pixel); the slope of each
- * linear piece must be shallower than -1 (e.g., -.4).
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable, using eight comma-separated integers without spaces. Here
- * the above example, using `\' to break the line for readability.
- *
- * {
- * FREETYPE_PROPERTIES=\

- /* */
- /* <Description> */
- /* The header file `fterrors.h' (which is automatically included by */

- /* with a small macro trick explained below. */
- /* */
- /* *Error* *Formats* */
- /* */
- /* The configuration macro FT_CONFIG_OPTION_USE_MODULE_ERRORS can be */
- /* defined in `ftoption.h' in order to make the higher byte indicate */
- /* the module where the error has happened (this is not compatible */
- /* with standard builds of FreeType 2, however). See the file */
- /* `ftmoderr.h' for more details. */

- /* applications to build a table of error message strings. The */
- /* strings are not included in a normal build of FreeType 2 to */
- /* save space (most client applications do not use them). */

- * @section:

- *
- * @title:
- * LCD Filtering
- *
- * @abstract:
- * Reduce color fringes of subpixel-rendered bitmaps.
- *
- * @description:
- * Subpixel rendering exploits the color-striped structure of LCD
- * pixels, increasing the available resolution in the direction of the
- * stripe (usually horizontal RGB) by a factor of~3. Since these
- * subpixels are color pixels, using them unfiltered creates severe
- * color fringes. Use the @FT_Library_SetLcdFilter API to specify a
- * low-pass filter, which is then applied to subpixel-rendered bitmaps
- * generated through @FT_Render_Glyph. The filter sacrifices some of
- * the higher resolution to reduce color fringes, making the glyph image
- * slightly blurrier. Positional improvements will remain.
- *
- * Note that no filter is active by default, and that this function is
- * *not* implemented in default builds of the library. You need to
- * #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
- * in order to activate it and explicitly call @FT_Library_SetLcdFilter
- * to enable it.
- *
- * A filter should have two properties:
- *
- * 1) It should be normalized, meaning the sum of the 5~components
- * should be 256 (0x100). It is possible to go above or under this
- * target sum, however: going under means tossing out contrast, going
- * over means invoking clamping and thereby non-linearities that
- * increase contrast somewhat at the expense of greater distortion
- * and color-fringing. Contrast is better enhanced through stem
- * darkening.
- *
- * 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
- * where a~+ b~=~c. It distributes the computed coverage for one
- * subpixel to all subpixels equally, sacrificing some won resolution
- * but drastically reducing color-fringing. Positioning improvements
- * remain! Note that color-fringing can only really be minimized
- * when using a color-balanced filter and alpha-blending the glyph
- * onto a surface in linear space; see @FT_Render_Glyph.
- *
- * Regarding the form, a filter can be a `boxy' filter or a `beveled'
- * filter. Boxy filters are sharper but are less forgiving of non-ideal
- * gamma curves of a screen (viewing angles!), beveled filters are
- * fuzzier but more tolerant.
- *
- * Examples:
- *
- * - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
- * normalized.
- *
- * - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
- * normalized.
- *
- * - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
- * balanced.
- *
- * - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
- * balanced.
- *
- * - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
- * balanced.
- *
- * - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
- * balanced.
- *
- * The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
- * @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
- * of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
- *
- * If this feature is activated, the dimensions of LCD glyph bitmaps are
- * either wider or taller than the dimensions of the corresponding
- * outline with regard to the pixel grid. For example, for
- * @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
- * 3~subpixels to the right. The bitmap offset values are adjusted
- * accordingly, so clients shouldn't need to modify their layout and
- * glyph positioning code when enabling the filter.
- *
- * It is important to understand that linear alpha blending and gamma
- * correction is critical for correctly rendering glyphs onto surfaces
- * without artifacts and even more critical when subpixel rendering is
- * involved.
- *
- * Each of the 3~alpha values (subpixels) is independently used to blend
- * one color channel. That is, red alpha blends the red channel of the
- * text color with the red channel of the background pixel. The
- * distribution of density values by the color-balanced filter assumes
- * alpha blending is done in linear space; only then color artifacts
- * cancel out.

- * @enum:
- * FT_LcdFilter
- *
- * @description:
- * A list of values to identify various types of LCD filters.
- *
- * @values:
- * FT_LCD_FILTER_NONE ::
- * Do not perform filtering. When used with subpixel rendering, this
- * results in sometimes severe color fringes.
- *
- * FT_LCD_FILTER_DEFAULT ::
- * The default filter reduces color fringes considerably, at the cost
- * of a slight blurriness in the output.
- *
- * It is a beveled, normalized, and color-balanced five-tap filter
- * that is more forgiving to screens with non-ideal gamma curves and
- * viewing angles. Note that while color-fringing is reduced, it can
- * only be minimized by using linear alpha blending and gamma
- * correction to render glyphs onto surfaces. The default filter
- * weights are [0x08 0x4D 0x56 0x4D 0x08].
- *
- * FT_LCD_FILTER_LIGHT ::
- * The light filter is a variant that is sharper at the cost of
- * slightly more color fringes than the default one.
- *
- * It is a boxy, normalized, and color-balanced three-tap filter that
- * is less forgiving to screens with non-ideal gamma curves and
- * viewing angles. This filter works best when the rendering system
- * uses linear alpha blending and gamma correction to render glyphs
- * onto surfaces. The light filter weights are
- * [0x00 0x55 0x56 0x55 0x00].
- *
- * FT_LCD_FILTER_LEGACY ::
- * This filter corresponds to the original libXft color filter. It
- * provides high contrast output but can exhibit really bad color
- * fringes if glyphs are not extremely well hinted to the pixel grid.
- * In other words, it only works well if the TrueType bytecode
- * interpreter is enabled *and* high-quality hinted fonts are used.
- *
- * This filter is only provided for comparison purposes, and might be
- * disabled or stay unsupported in the future.
- *
- * FT_LCD_FILTER_LEGACY1 ::
- * For historical reasons, the FontConfig library returns a different
- * enumeration value for legacy LCD filtering. To make code work that
- * (incorrectly) forwards FontConfig's enumeration value to
- * @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
- * to have another enumeration value, which is completely equal to
- * `FT_LCD_FILTER_LEGACY'.

- * Calling the internal function `FT_Stream_Close' on the new stream will

- * objects will be released to the heap.
- *
- * The stream implementation is very basic and resets the decompression
- * process each time seeking backwards is needed within the stream
- *
- * In certain builds of the library, LZW compression recognition is
- * automatically handled when calling @FT_New_Face or @FT_Open_Face.
- * This means that if no font driver is capable of handling the raw
- * compressed file, the library will try to open a LZW stream from it

- /* */
- /* If the macro FT_CONFIG_OPTION_USE_MODULE_ERRORS in `ftoption.h' is */
- /* set, the lower byte of an error value identifies the error code as */
- /* usual. In addition, the higher byte identifies the module. For */
- /* example, the error `FT_Err_Invalid_File_Format' has value 0x0003, the */
- /* error `TT_Err_Invalid_File_Format' has value 0x1303, the error */
- /* `T1_Err_Invalid_File_Format' has value 0x1403, etc. */
- /* */
- /* Note that `FT_Err_Ok', `TT_Err_Ok', etc. are always equal to zero, */
- /* including the high byte. */
- /* */
- /* If FT_CONFIG_OPTION_USE_MODULE_ERRORS isn't set, the higher byte of */
- /* an error value is set to zero. */
- /* */
- /* To hide the various `XXX_Err_' prefixes in the source code, FreeType */
- /* provides some macros in `fttypes.h'. */
- /* */
- /* FT_ERR( err ) */

- /* the line */
- /* */
- /* error = FT_ERR( Invalid_Outline ); */
- /* */
- /* expands to */
- /* */
- /* error = BDF_Err_Invalid_Outline; */
- /* */
- /* For simplicity, you can always use `FT_Err_Ok' directly instead */
- /* of `FT_ERR( Ok )'. */
- /* */
- /* FT_ERR_EQ( errcode, err ) */
- /* FT_ERR_NEQ( errcode, err ) */
- /* Compare error code `errcode' with the error `err' for equality */
- /* and inequality, respectively. Example: */
- /* */
- /* if ( FT_ERR_EQ( error, Invalid_Outline ) ) */
- /* ... */
- /* */
- /* Using this macro you don't have to think about error prefixes. */
- /* Of course, if module errors are not active, the above example is */
- /* the same as */
- /* */
- /* if ( error == FT_Err_Invalid_Outline ) */

- /* */
- /* FT_ERROR_BASE( errcode ) */

- * cannot select some fonts at all. The improve this situation, the PCF
- * module prepends the foundry name (plus a space) to the family name.
- * It also checks whether there are `wide' characters; all put together,
- * family names like `Sony Fixed' or `Misc Fixed Wide' are constructed.

- * @section:

- *
- * @title:
- * The TrueType driver
- *
- * @abstract:
- * Controlling the TrueType driver module.
- *
- * @description:
- * While FreeType's TrueType driver doesn't expose API functions by
- * itself, it is possible to control its behaviour with @FT_Property_Set
- * and @FT_Property_Get. The following lists the available properties
- * together with the necessary macros and structures.
- *
- * The TrueType driver's module name is `truetype'.
- *
- * We start with a list of definitions, kindly provided by Greg
- * Hitchcock.
- *
- * _Bi-Level_ _Rendering_
- *
- * Monochromatic rendering, exclusively used in the early days of
- * TrueType by both Apple and Microsoft. Microsoft's GDI interface
- * supported hinting of the right-side bearing point, such that the
- * advance width could be non-linear. Most often this was done to
- * achieve some level of glyph symmetry. To enable reasonable
- * performance (e.g., not having to run hinting on all glyphs just to
- * get the widths) there was a bit in the head table indicating if the
- * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
- * cache hinting widths across multiple sizes and device aspect ratios.
- *
- * _Font_ _Smoothing_
- *
- * Microsoft's GDI implementation of anti-aliasing. Not traditional
- * anti-aliasing as the outlines were hinted before the sampling. The
- * widths matched the bi-level rendering.
- *
- * _ClearType_ _Rendering_
- *
- * Technique that uses physical subpixels to improve rendering on LCD
- * (and other) displays. Because of the higher resolution, many methods
- * of improving symmetry in glyphs through hinting the right-side
- * bearing were no longer necessary. This lead to what GDI calls
- * `natural widths' ClearType, see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
- * has extra resolution, most non-linearity went away, but it is still
- * possible for hints to change the advance widths in this mode.
- *
- * _ClearType_ _Compatible_ _Widths_
- *
- * One of the earliest challenges with ClearType was allowing the
- * implementation in GDI to be selected without requiring all UI and
- * documents to reflow. To address this, a compatible method of
- * rendering ClearType was added where the font hints are executed once
- * to determine the width in bi-level rendering, and then re-run in
- * ClearType, with the difference in widths being absorbed in the font
- * hints for ClearType (mostly in the white space of hints); see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
- * definition, compatible width ClearType allows for non-linear widths,
- * but only when the bi-level version has non-linear widths.
- *
- * _ClearType_ _Subpixel_ _Positioning_
- *
- * One of the nice benefits of ClearType is the ability to more crisply
- * display fractional widths; unfortunately, the GDI model of integer
- * bitmaps did not support this. However, the WPF and Direct Write
- * frameworks do support fractional widths. DWrite calls this `natural
- * mode', not to be confused with GDI's `natural widths'. Subpixel
- * positioning, in the current implementation of Direct Write,
- * unfortunately does not support hinted advance widths, see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
- * TrueType interpreter fully allows the advance width to be adjusted in
- * this mode, just the DWrite client will ignore those changes.
- *
- * _ClearType_ _Backward_ _Compatibility_
- *
- * This is a set of exceptions made in the TrueType interpreter to
- * minimize hinting techniques that were problematic with the extra
- * resolution of ClearType; see
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
- * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
- * This technique is not to be confused with ClearType compatible
- * widths. ClearType backward compatibility has no direct impact on
- * changing advance widths, but there might be an indirect impact on
- * disabling some deltas. This could be worked around in backward
- * compatibility mode.
- *
- * _Native_ _ClearType_ _Mode_
- *
- * (Not to be confused with `natural widths'.) This mode removes all
- * the exceptions in the TrueType interpreter when running with
- * ClearType. Any issues on widths would still apply, though.
- *

- *
- * @property:
- * interpreter-version
- *
- * @description:
- * Currently, three versions are available, two representing the
- * bytecode interpreter with subpixel hinting support (old `Infinality'
- * code and new stripped-down and higher performance `minimal' code) and
- * one without, respectively. The default is subpixel support if
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
- * otherwise (since it isn't available then).
- *
- * If subpixel hinting is on, many TrueType bytecode instructions behave
- * differently compared to B/W or grayscale rendering (except if `native
- * ClearType' is selected by the font). Microsoft's main idea is to
- * render at a much increased horizontal resolution, then sampling down
- * the created output to subpixel precision. However, many older fonts
- * are not suited to this and must be specially taken care of by
- * applying (hardcoded) tweaks in Microsoft's interpreter.
- *
- * Details on subpixel hinting and some of the necessary tweaks can be
- * found in Greg Hitchcock's whitepaper at
- * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
- * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
- * or 6x5 supersampling) like discussed in the paper. Depending on the
- * chosen interpreter, it simply ignores instructions on vertical stems
- * to arrive at very similar results.
- *
- * The following example code demonstrates how to deactivate subpixel
- * hinting (omitting the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "truetype",
- * "interpreter-version",
- * &interpreter_version );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable (using values `35', `38', or `40').
- */

- /**************************************************************************
- *
- * @enum:
- * TT_INTERPRETER_VERSION_XXX
- *
- * @description:
- * A list of constants used for the @interpreter-version property to
- * select the hinting engine for Truetype fonts.
- *
- * The numeric value in the constant names represents the version
- * number as returned by the `GETINFO' bytecode instruction.
- *
- * @values:
- * TT_INTERPRETER_VERSION_35 ::
- * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
- * Windows~98; only grayscale and B/W rasterizing is supported.
- *
- * TT_INTERPRETER_VERSION_38 ::
- * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as can
- * be found, for example, in the Internet Explorer~9 running on
- * Windows~7). It is used in FreeType to select the `Infinality'
- * subpixel hinting code. The code may be removed in a future
- * version.
- *
- * TT_INTERPRETER_VERSION_40 ::
- * Version~40 corresponds to MS rasterizer v.2.1; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as can
- * be found, for example, in Microsoft's Edge Browser on Windows~10).
- * It is used in FreeType to select the `minimal' subpixel hinting
- * code, a stripped-down and higher performance version of the
- * `Infinality' code.
- *
- * @note:
- * This property controls the behaviour of the bytecode interpreter
- * and thus how outlines get hinted. It does *not* control how glyph
- * get rasterized! In particular, it does not control subpixel color
- * filtering.
- *
- * If FreeType has not been compiled with the configuration option
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
- * an `FT_Err_Unimplemented_Feature' error.
- *
- * Depending on the graphics framework, Microsoft uses different
- * bytecode and rendering engines. As a consequence, the version
- * numbers returned by a call to the `GETINFO' bytecode instruction are
- * more convoluted than desired.
- *
- * Here are two tables that try to shed some light on the possible
- * values for the MS rasterizer engine, together with the additional
- * features introduced by it.
- *
- * {
- * GETINFO framework version feature
- * -------------------------------------------------------------------
- * 3 GDI (Win 3.1), v1.0 16-bit, first version
- * TrueImage
- * 33 GDI (Win NT 3.1), v1.5 32-bit
- * HP Laserjet
- * 34 GDI (Win 95) v1.6 font smoothing,
- * new SCANTYPE opcode
- * 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
- * bits in composite glyphs
- * 36 MGDI (Win CE 2) v1.6+ classic ClearType
- * 37 GDI (XP and later), v1.8 ClearType
- * GDI+ old (before Vista)
- * 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
- * WPF Y-direction ClearType,
- * additional error checking
- * 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
- * in GETINFO opcode,
- * bug fixes
- * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
- * DWrite (Win 8) in GETINFO opcode,
- * Gray ClearType
- * }
- *
- * The `version' field gives a rough orientation only, since some
- * applications provided certain features much earlier (as an example,
- * Microsoft Reader used subpixel and Y-direction ClearType already in
- * Windows 2000). Similarly, updates to a given framework might include
- * improved hinting support.
- *
- * {
- * version sampling rendering comment
- * x y x y
- * --------------------------------------------------------------
- * v1.0 normal normal B/W B/W bi-level
- * v1.6 high high gray gray grayscale
- * v1.8 high normal color-filter B/W (GDI) ClearType
- * v1.9 high high color-filter gray Color ClearType
- * v2.1 high normal gray B/W Gray ClearType
- * v2.1 high high gray gray Gray ClearType
- * }
- *
- * Color and Gray ClearType are the two available variants of
- * `Y-direction ClearType', meaning grayscale rasterization along the
- * Y-direction; the name used in the TrueType specification for this
- * feature is `symmetric smoothing'. `Classic ClearType' is the
- * original algorithm used before introducing a modified version in
- * Win~XP. Another name for v1.6's grayscale rendering is `font
- * smoothing', and `Color ClearType' is sometimes also called `DWrite
- * ClearType'. To differentiate between today's Color ClearType and the
- * earlier ClearType variant with B/W rendering along the vertical axis,
- * the latter is sometimes called `GDI ClearType'.
- *
- * `Normal' and `high' sampling describe the (virtual) resolution to
- * access the rasterized outline after the hinting process. `Normal'
- * means 1 sample per grid line (i.e., B/W). In the current Microsoft
- * implementation, `high' means an extra virtual resolution of 16x16 (or
- * 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
- * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
- * lines for color filtering if Color ClearType is activated.
- *
- * Note that `Gray ClearType' is essentially the same as v1.6's
- * grayscale rendering. However, the GETINFO instruction handles it
- * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
- * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
- * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
- * the version~1 gasp table exclusively (like Color ClearType), while
- * v1.6 only respects the values of version~0 (bits 0 and~1).
- *
- * Keep in mind that the features of the above interpreter versions
- * might not map exactly to FreeType features or behavior because it is
- * a fundamentally different library with different internals.

- *
- * @description:
- * A list of valid values for the `charset' byte in
- * @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX
- * encodings (except for cp1361) can be found at
- * ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
- * subdirectory. cp1361 is roughly a superset of
- * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
- *
- * @values:
- * FT_WinFNT_ID_DEFAULT ::
- * This is used for font enumeration and font creation as a
- * `don't care' value. Valid font files don't contain this value.
- * When querying for information about the character set of the font
- * that is currently selected into a specified device context, this
- * return value (of the related Windows API) simply denotes failure.
- *
- * FT_WinFNT_ID_SYMBOL ::
- * There is no known mapping table available.
- *
- * FT_WinFNT_ID_MAC ::
- * Mac Roman encoding.
- *
- * FT_WinFNT_ID_OEM ::
- * From Michael Pöttgen <michael@poettgen.de>:
- *
- * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
- * is used for the charset of vector fonts, like `modern.fon',
- * `roman.fon', and `script.fon' on Windows.
- *
- * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
- * specifies a character set that is operating-system dependent.
- *
- * The `IFIMETRICS' documentation from the `Windows Driver
- * Development Kit' says: This font supports an OEM-specific
- * character set. The OEM character set is system dependent.
- *
- * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
- * second default codepage that most international versions of
- * Windows have. It is one of the OEM codepages from
- *
- * https://msdn.microsoft.com/en-us/goglobal/bb964655,
- *
- * and is used for the `DOS boxes', to support legacy applications.
- * A German Windows version for example usually uses ANSI codepage
- * 1252 and OEM codepage 850.
- *
- * FT_WinFNT_ID_CP874 ::
- * A superset of Thai TIS 620 and ISO 8859-11.
- *
- * FT_WinFNT_ID_CP932 ::
- * A superset of Japanese Shift-JIS (with minor deviations).
- *
- * FT_WinFNT_ID_CP936 ::
- * A superset of simplified Chinese GB 2312-1980 (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP949 ::
- * A superset of Korean Hangul KS~C 5601-1987 (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP950 ::
- * A superset of traditional Chinese Big~5 ETen (with different
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP1250 ::
- * A superset of East European ISO 8859-2 (with slightly different
- * ordering).
- *
- * FT_WinFNT_ID_CP1251 ::
- * A superset of Russian ISO 8859-5 (with different ordering).
- *
- * FT_WinFNT_ID_CP1252 ::
- * ANSI encoding. A superset of ISO 8859-1.
- *
- * FT_WinFNT_ID_CP1253 ::
- * A superset of Greek ISO 8859-7 (with minor modifications).
- *
- * FT_WinFNT_ID_CP1254 ::
- * A superset of Turkish ISO 8859-9.
- *
- * FT_WinFNT_ID_CP1255 ::
- * A superset of Hebrew ISO 8859-8 (with some modifications).
- *
- * FT_WinFNT_ID_CP1256 ::
- * A superset of Arabic ISO 8859-6 (with different ordering).

- *
- * FT_WinFNT_ID_CP1258 ::

- *
- * @function:
- * FT_Get_PS_Font_Value
- *
- * @description:
- * Retrieve the value for the supplied key from a PostScript font.
- *
- * @input:
- * face ::
- * PostScript face handle.
- *
- * key ::
- * An enumeration value representing the dictionary key to retrieve.
- *
- * idx ::
- * For array values, this specifies the index to be returned.
- *
- * value ::
- * A pointer to memory into which to write the value.
- *
- * valen_len ::
- * The size, in bytes, of the memory supplied for the value.
- *
- * @output:
- * value ::
- * The value matching the above key, if it exists.
- *
- * @return:
- * The amount of memory (in bytes) required to hold the requested
- * value (if it exists, -1 otherwise).
- *
- * @note:
- * The values returned are not pointers into the internal structures of
- * the face, but are `fresh' copies, so that the memory containing them
- * belongs to the calling application. This also enforces the
- * `read-only' nature of these values, i.e., this function cannot be
- * used to manipulate the face.
- *
- * `value' is a void pointer because the values returned can be of
- * various types.
- *
- * If either `value' is NULL or `value_len' is too small, just the
- * required memory size for the requested entry is returned.
- *
- * The `idx' parameter is used, not only to retrieve elements of, for
- * example, the FontMatrix or FontBBox, but also to retrieve name keys
- * from the CharStrings dictionary, and the charstrings themselves. It
- * is ignored for atomic values.
- *
- * PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
- * get the value as in the font stream, you need to divide by
- * 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
- *
- * IMPORTANT: Only key/value pairs read by the FreeType interpreter can
- * be retrieved. So, for example, PostScript procedures such as NP,
- * ND, and RD are not available. Arbitrary keys are, obviously, not be
- * available either.

-// Auto-fitter data for blue strings.
-//
-// Copyright 2013-2017 by
-// David Turner, Robert Wilhelm, and Werner Lemberg.
-//
-// This file is part of the FreeType project, and may only be used,

-
-
-// This file contains data specific to blue zones. It gets processed by
-// a script to simulate `jagged arrays', with enumeration values holding
-// offsets into the arrays.
-//
-// The format of the file is rather simple: A section starts with three
-// labels separated by whitespace and followed by a colon (everything in a
-// single line); the first label gives the name of the enumeration template,
-// the second the name of the array template, and the third the name of the
-// `maximum' template. The script then fills the corresponding templates
-// (indicated by `@' characters around the name).
-//
-// A section contains one or more data records. Each data record consists
-// of two or more lines. The first line holds the enumeration name, and the
-// remaining lines the corresponding array data.
-//
-// There are two possible representations for array data.
-//
-// - A string of characters or character clusters (for example, representing
-// Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
-// quotes, using C syntax, where the elements are separated by spaces.
-// There can be only one string per line, thus the starting and ending
-// double quote must be the first and last character in the line,
-// respectively, ignoring whitespace before and after the string. If
-// there are multiple strings (in multiple lines), they are concatenated
-// to a single string. In the output, a string gets represented as a
-// series of singles bytes, followed by a zero byte. The enumeration
-// values simply hold byte offsets to the start of the corresponding
-// strings.
-//
-// For strings, the `maximum' template holds the maximum number of
-// non-space characters in all strings.
-//
-// - Data blocks enclosed in balanced braces, which get copied verbatim and
-// which can span multiple lines. The opening brace of a block must be
-// the first character of a line (ignoring whitespace), and the closing
-// brace the last (ignoring whitespace also). The script appends a comma
-// character after each block and counts the number of blocks to set the
-// enumeration values.
-//
-// For data blocks, the `maximum' template holds the maximum number of
-// array elements.
-//
-// A section can contain either strings only or data blocks only.
-//
-// A comment line starts with `//'; it gets removed. A preprocessor
-// directive line (using the standard syntax of `cpp') starts with `#' and
-// gets copied verbatim to both the enumeration and the array. Whitespace
-// outside of a string is insignificant.
-//
-// Preprocessor directives are ignored while the script computes maximum
-// values; this essentially means that the maximum values can easily be too
-// large. Given that the purpose of those values is to create local
-// fixed-size arrays at compile time for further processing of the blue zone
-// data, this isn't a problem. Note the final zero byte of a string is not
-// counted. Note also that the count holds the number of UTF-8 encoded
-// characters, not bytes.

-// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
-//
-// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
-// explanations.
-//
-// A blue zone in general is defined by a reference and an overshoot line.
-// During the hinting process, all coordinate values between those two lines
-// are set equal to the reference value, provided that the blue zone is not
-// wider than 0.75 pixels (otherwise the blue zone gets ignored). All
-// entries must have `AF_BLUE_STRING_MAX' as the final line.
-//
-// During the glyph analysis, edges are sorted from bottom to top, and then
-// sequentially checked, edge by edge, against the blue zones in the order
-// given below.
-//
-//
-// latin auto-hinter
-// -----------------
-//
-// Characters in a blue string are automatically classified as having a flat
-// (reference) or a round (overshoot) extremum. The blue zone is then set
-// up by the mean values of all flat extrema and all round extrema,
-// respectively. Only horizontal blue zones (i.e., adjusting vertical
-// coordinate values) are supported.
-//
-// Some scripts like Khmer need character composition to get all necessary
-// blue zones, since Unicode only provides an abstract data model that
-// doesn't represent all possible glyph shapes. For such character
-// clusters, the HarfBuzz library is used to convert them into the
-// corresponding glyphs. The largest glyph element (where `largest' can be
-// either `largest ascender' or `largest descender') then defines the
-// corresponding flat or round extremum.
-//
-// For the latin auto-hinter, the overshoot should be larger than the
-// reference for top zones, and vice versa for bottom zones.
-//
-// LATIN_TOP
-// Take the maximum flat and round coordinate values of the blue string
-// characters for computing the blue zone's reference and overshoot
-// values.
-//
-// If not set, take the minimum values.
-//
-// Mutually exclusive with `LATIN_SUB_TOP'.
-//
-// LATIN_SUB_TOP
-// For all glyphs of a character cluster, compute the maximum flat
-// and round coordinate values of each component, then take the
-// smallest of the maximum values. The idea is to get the top of
-// subscript glyphs, as used in Khmer, for example. Note that
-// this mechanism doesn't work for ordinary ligatures.
-//
-// This flags indicates a secondary blue zone: It gets removed if
-// there is a non-LATIN_SUB_TOP blue zone at the same coordinate
-// value (after scaling).
-//
-// Mutually exclusive with `LATIN_TOP'.
-//
-// LATIN_NEUTRAL
-// Ignore round extrema and define the blue zone with flat values only.
-// Both top and bottom of contours can match. This is useful for
-// scripts like Devanagari where vowel signs attach to the base
-// character and are implemented as components of composite glyphs.
-//
-// If not set, both round and flat extrema are taken into account.
-// Additionally, only the top or the bottom of a contour can match,
-// depending on the LATIN_TOP flag.
-//
-// Neutral blue zones should always follow non-neutral blue zones.
-//
-// LATIN_X_HEIGHT
-// Scale all glyphs vertically from the corresponding script to make the
-// reference line of this blue zone align on the grid. The scaling
-// takes place before all other blue zones get aligned to the grid.
-// Only one blue character string of a script style can have this flag.
-//
-// LATIN_LONG
-// Apply an additional constraint for blue zone values: Don't
-// necessarily use the extremum as-is but a segment of the topmost (or
-// bottommost) contour that is longer than a heuristic threshold, and
-// which is not too far away vertically from the real extremum. This
-// ensures that small bumps in the outline are ignored (for example, the
-// `vertical serifs' found in many Hebrew glyph designs).
-//
-// The segment must be at least EM/25 font units long, and the distance
-// to the extremum must be smaller than EM/4.
-//
-//
-// cjk auto-hinter
-// ---------------
-//
-// Characters in a blue string are *not* automatically classified. Instead,
-// first come the characters used for the overshoot value, then the
-// character `|', then the characters used for the reference value
-// (everything separated by space characters). The blue zone is then set up
-// by the mean values of all reference values and all overshoot values,
-// respectively. Both horizontal and vertical blue zones (i.e., adjusting
-// vertical and horizontal coordinate values, respectively) are supported.
-//
-// For the cjk auto-hinter, the overshoot should be smaller than the
-// reference for top zones, and vice versa for bottom zones.
-//
-// CJK_TOP
-// Take the maximum flat and round coordinate values of the blue string
-// characters. If not set, take the minimum values.
-//
-// CJK_RIGHT
-// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the
-// right blue zone, taking horizontal maximum values.
-//
-// CJK_HORIZ
-// Define a blue zone for horizontal hinting (i.e., vertical blue
-// zones). If not set, this is a blue zone for vertical hinting.

- * The following explanations are mostly taken from the article
- *
- * Real-Time Grid Fitting of Typographic Outlines
- *

- *
- * http://www.tug.org/TUGboat/Articles/tb24-3/lemberg.pdf
- *
- * with appropriate updates.
- *
- *
- * Segments
- *
- * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
- * find segments in an outline.
- *
- * A segment is a series of at least two consecutive points that are
- * approximately aligned along a coordinate axis. The analysis to do
- * so is specific to a writing system.
- *
- *
- * Edges
- *
- * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
- * edges.
- *
- * As soon as segments are defined, the auto-hinter groups them into
- * edges. An edge corresponds to a single position on the main
- * dimension that collects one or more segments (allowing for a small
- * threshold).
- *
- * As an example, the `latin' writing system first tries to grid-fit
- * edges, then to align segments on the edges unless it detects that
- * they form a serif.

- *
- *
- * Stems
- *
- * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- * Segments need to be `linked' to other ones in order to detect stems.
- * A stem is made of two segments that face each other in opposite
- * directions and that are sufficiently close to each other. Using
- * vocabulary from the TrueType specification, stem segments form a
- * `black distance'.
- *
- * In the above ASCII drawing, the horizontal segments are BC, DE, and
- * FG; the vertical segments are AB, CD, EF, and GH.
- *
- * Each segment has at most one `best' candidate to form a black
- * distance, or no candidate at all. Notice that two distinct segments
- * can have the same candidate, which frequently means a serif.
- *
- * A stem is recognized by the following condition:
- *
- * best segment_1 = segment_2 && best segment_2 = segment_1
- *
- * The best candidate is stored in field `link' in structure
- * `AF_Segment'.
- *
- * In the above ASCII drawing, the best candidate for both AB and CD is
- * GH, while the best candidate for GH is AB. Similarly, the best
- * candidate for EF and GH is AB, while the best candidate for AB is
- * GH.
- *
- * The detection and handling of stems is dependent on the writing
- * system.
- *
- *
- * Serifs
- *
- * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
- *
- * In comparison to a stem, a serif (as handled by the auto-hinter
- * module that takes care of the `latin' writing system) has
- *
- * best segment_1 = segment_2 && best segment_2 != segment_1
- *
- * where segment_1 corresponds to the serif segment (CD and EF in the
- * above ASCII drawing).
- *
- * The best candidate is stored in field `serif' in structure
- * `AF_Segment' (and `link' is set to NULL).
- *
- *
- * Touched points
- *
- * A point is called `touched' if it has been processed somehow by the
- * auto-hinter. It basically means that it shouldn't be moved again
- * (or moved only under certain constraints to preserve the already
- * applied processing).
- *
- *
- * Flat and round segments
- *
- * Segments are `round' or `flat', depending on the series of points
- * that define them. A segment is round if the next and previous point
- * of an extremum (which can be either a single point or sequence of
- * points) are both conic or cubic control points. Otherwise, a
- * segment with an extremum is flat.
- *
- *
- * Strong Points
- *
- * Experience has shown that points not part of an edge need to be
- * interpolated linearly between their two closest edges, even if these
- * are not part of the contour of those particular points. Typical
- * candidates for this are
- *
- * - angle points (i.e., points where the `in' and `out' direction
- * differ greatly)
- *
- * - inflection points (i.e., where the `in' and `out' angles are the
- * same, but the curvature changes sign) [currently, such points
- * aren't handled specially in the auto-hinter]
- *
- * `af_glyph_hints_align_strong_points' is the function that takes
- * care of such situations; it is equivalent to the TrueType `IP'
- * hinting instruction.
- *
- *
- * Weak Points
- *
- * Other points in the outline must be interpolated using the
- * coordinates of their previous and next unfitted contour neighbours.
- * These are called `weak points' and are touched by the function
- * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
- * hinting instruction. Typical candidates are control points and
- * points on the contour without a major direction.
- *
- * The major effect is to reduce possible distortion caused by
- * alignment of edges and strong points, thus weak points are processed
- * after strong points.

- *
- * - Next comes the default style, using the character ranges as defined

- * Note that there also exist fallback scripts, mainly covering

- * Various OpenType features might use the same glyphs at different
- * vertical positions; for example, superscript and subscript glyphs
- * could be the same. However, the auto-hinter is completely
- * agnostic of OpenType features after the feature analysis has been
- * completed: The engine then simply receives a glyph index and returns a
- * hinted and usually rendered glyph.
- *
- * Consider the superscript feature of font `pala.ttf': Some of the
- * glyphs are `real', this is, they have a zero vertical offset, but
- * most of them are small caps glyphs shifted up to the superscript
- * position (this is, the `sups' feature is present in both the GSUB and
- * GPOS tables). The code for blue zones computation actually uses a
- * feature's y offset so that the `real' glyphs get correct hints. But
- * later on it is impossible to decide whether a glyph index belongs to,
- * say, the small caps or superscript feature.
- *
- * For this reason, we don't assign a style to a glyph if the current
- * feature covers the glyph in both the GSUB and the GPOS tables. This
- * is quite a broad condition, assuming that
- *
- * (a) glyphs that get used in multiple features are present in a
- * feature without vertical shift,
- *
- * and
- *
- * (b) a feature's GPOS data really moves the glyph vertically.
- *
- * Not fulfilling condition (a) makes a font larger; it would also
- * reduce the number of glyphs that could be addressed directly without
- * using OpenType features, so this assumption is rather strong.
- *
- * Condition (b) is much weaker, and there might be glyphs which get
- * missed. However, the OpenType features we are going to handle are
- * primarily located in GSUB, and HarfBuzz doesn't provide an API to
- * directly get the necessary information from the GPOS table. A
- * possible solution might be to directly parse the GPOS table to find
- * out whether a glyph gets shifted vertically, but this is something I
- * would like to avoid if not really necessary.
- *
- * Note that we don't follow this logic for the default coverage.
- * Complex scripts like Devanagari have mandatory GPOS features to
- * position many glyph elements, using mark-to-base or mark-to-ligature
- * tables; the number of glyphs missed due to condition (b) would be far
- * too large.

- * Usually, a font contains more glyphs than can be addressed by its
- * character map.
- *
- * In the PostScript font world, encoding vectors specific to a given
- * task are used to select such glyphs, and these glyphs can be often
- * recognized by having a suffix in its glyph names. For example, a
- * superscript glyph `A' might be called `A.sup'. Unfortunately, this
- * naming scheme is not standardized and thus unusable for us.
- *
- * In the OpenType world, a better solution was invented, namely
- * `features', which cleanly separate a character's input encoding from
- * the corresponding glyph's appearance, and which don't use glyph names
- * at all. For our purposes, and slightly generalized, an OpenType
- * feature is a name of a mapping that maps character codes to
- * non-standard glyph indices (features get used for other things also).
- * For example, the `sups' feature provides superscript glyphs, thus
- * mapping character codes like `A' or `B' to superscript glyph
- * representation forms. How this mapping happens is completely
- * uninteresting to us.
- *
- * For the auto-hinter, a `coverage' represents all glyphs of an OpenType
- * feature collected in a set (as listed below) that can be hinted
- * together. To continue the above example, superscript glyphs must not
- * be hinted together with normal glyphs because the blue zones
- * completely differ.
- *
- * Note that FreeType itself doesn't compute coverages; it only provides
- * the glyphs addressable by the default Unicode character map. Instead,
- * we use the HarfBuzz library (if available), which has many functions
- * exactly for this purpose.
- *
- * AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
- * listed separately (including the glyphs addressable by the character
- * map). In case HarfBuzz isn't available, it exactly covers the glyphs
- * addressable by the character map.

- Notes
-
- Mac suitcase files can (and often do!) contain multiple fonts. To
- support this I use the face_index argument of FT_(Open|New)_Face()
- functions, and pretend the suitcase file is a collection.
-
- Warning: fbit and NFNT bitmap resources are not supported yet. In old
- sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
- resources instead of the `bdat' table in the sfnt resource. Therefore,
- face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
- resource is unavailable at present.
-
- The Mac FOND support works roughly like this:
-
- - Check whether the offered stream points to a Mac suitcase file. This
- is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
- stream that gets passed to our init_face() routine is a stdio stream,
- which isn't usable for us, since the FOND resources live in the
- resource fork. So we just grab the stream->pathname field.
-
- - Read the FOND resource into memory, then check whether there is a
- TrueType font and/or(!) a Type 1 font available.
-
- - If there is a Type 1 font available (as a separate `LWFN' file), read
- its data into memory, massage it slightly so it becomes PFB data, wrap
- it into a memory stream, load the Type 1 driver and delegate the rest
- of the work to it by calling FT_Open_Face(). (XXX TODO: after this
- has been done, the kerning data from the FOND resource should be
- appended to the face: On the Mac there are usually no AFM files
- available. However, this is tricky since we need to map Mac char
- codes to ps glyph names to glyph ID's...)
-
- - If there is a TrueType font (an `sfnt' resource), read it into memory,
- wrap it into a memory stream, load the TrueType driver and delegate
- the rest of the work to it, by calling FT_Open_Face().
-
- - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
- itself, even though it doesn't contains `POST' resources. To handle
- this special case without opening the file an extra time, we just
- ignore errors from the `LWFN' and fallback to the `sfnt' if both are
- available.

- FreeType font driver for BDF fonts
-
- Francesco Zappa Nardelli
- <francesco.zappa.nardelli@ens.fr>
-
-
-Introduction
-************
-
-BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
-which is intended to be easily understood by both humans and computers.
-This code implements a BDF driver for the FreeType library, following the
-Adobe Specification V 2.2. The specification of the BDF font format is
-available from Adobe's web site:
-
- http://partners.adobe.com/public/developer/en/font/5005.BDF_Spec.pdf
-
-Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
-They do not define vertical metrics, because the X Consortium BDF
-specification has removed them.
-
-
-Encodings
-*********
-
-The variety of encodings that accompanies bdf fonts appears to encompass the
-small set defined in freetype.h. On the other hand, two properties that
-specify encoding and registry are usually defined in bdf fonts.
-
-I decided to make these two properties directly accessible, leaving to the
-client application the work of interpreting them. For instance:
-
-
- #include FT_INTERNAL_BDF_TYPES_H
-
- FT_Face face;
- BDF_Public_Face bdfface;
-
-
- FT_New_Face( library, ..., &face );
-
- bdfface = (BDF_Public_Face)face;
-
- if ( ( bdfface->charset_registry == "ISO10646" ) &&
- ( bdfface->charset_encoding == "1" ) )
- [..]
-
-
-Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
-FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
-value given as argument into the corresponding glyph number.
-
-If the two properties are not available, Adobe Standard Encoding should be
-assumed.
-
-
-Anti-Aliased Bitmaps
-********************
-
-The driver supports an extension to the BDF format as used in Mark Leisher's
-xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in
-that format for adding anti-aliased them to TrueType fonts. It introduces a
-fourth field to the `SIZE' keyword which gives the bpp value (bits per
-pixel) of the glyph data in the font. Possible values are 1 (the default),
-2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The
-driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
-per pixel (using 4, 16, and 256 gray levels, respectively).
-
-
-Known problems
-**************
-
-- A font is entirely loaded into memory. Obviously, this is not the Right
- Thing(TM). If you have big fonts I suggest you convert them into PCF
- format (using the bdftopcf utility): the PCF font drive of FreeType can
- perform incremental glyph loading.
-
-When I have some time, I will implement on-demand glyph parsing.
-
-- Except for encodings properties, client applications have no visibility of
- the PCF_Face object. This means that applications cannot directly access
- font tables and must trust FreeType.
-
-- Currently, glyph names are ignored.
-
- I plan to give full visibility of the BDF_Face object in an upcoming
- revision of the driver, thus implementing also glyph names.
-
-- As I have never seen a BDF font that defines vertical metrics, vertical
- metrics are (parsed and) discarded. If you own a BDF font that defines
- vertical metrics, please let me know (I will implement them in 5-10
- minutes).

- /*
- *
- * FTC_GCache is an _abstract_ cache object optimized to store glyph
- * data. It works as follows:
- *
- * - It manages FTC_GNode objects. Each one of them can hold one or more
- * glyph `items'. Item types are not specified in the FTC_GCache but
- * in classes that extend it.
- *
- * - Glyph attributes, like face ID, character size, render mode, etc.,
- * can be grouped into abstract `glyph families'. This avoids storing
- * the attributes within the FTC_GCache, since it is likely that many
- * FTC_GNodes will belong to the same family in typical uses.
- *
- * - Each FTC_GNode is thus an FTC_Node with two additional fields:
- *
- * * gindex: A glyph index, or the first index in a glyph range.
- * * family: A pointer to a glyph `family'.
- *
- * - Family types are not fully specific in the FTC_Family type, but
- * by classes that extend it.
- *
- * Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
- * They share an FTC_Family sub-class called FTC_BasicFamily which is
- * used to store the following data: face ID, pixel/point sizes, load
- * flags. For more details see the file `src/cache/ftcbasic.c'.
- *
- * Client applications can extend FTC_GNode with their own FTC_GNode
- * and FTC_Family sub-classes to implement more complex caches (e.g.,
- * handling automatic synthesis, like obliquing & emboldening, colored
- * glyphs, etc.).
- *
- * See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
- * `ftcsbits.h', which both extend FTC_GCache with additional
- * optimizations.
- *
- * A typical FTC_GCache implementation must provide at least the
- * following:
- *
- * - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
- * my_node_new (must call FTC_GNode_Init)
- * my_node_free (must call FTC_GNode_Done)
- * my_node_compare (must call FTC_GNode_Compare)
- * my_node_remove_faceid (must call ftc_gnode_unselect in case
- * of match)
- *
- * - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
- * my_family_compare
- * my_family_init
- * my_family_reset (optional)
- * my_family_done
- *
- * - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
- * data.
- *
- * - Constant structures for a FTC_GNodeClass.
- *
- * - MyCacheNew() can be implemented easily as a call to the convenience
- * function FTC_GCache_New.
- *
- * - MyCacheLookup with a call to FTC_GCache_Lookup. This function will
- * automatically:
- *
- * - Search for the corresponding family in the cache, or create
- * a new one if necessary. Put it in FTC_GQUERY(myquery).family
- *
- * - Call FTC_Cache_Lookup.
- *
- * If it returns NULL, you should create a new node, then call
- * ftc_cache_add as usual.

- *
- * The correct thing to do is to use @FTC_CACHE_TRYLOOP and
- * @FTC_CACHE_TRYLOOP_END in order to implement a retry loop
- * that is capable of flushing the cache incrementally when
- * an OOM errors occur.
- *
- * However, we need to `lock' the node before this operation to
- * prevent it from being flushed within the loop.
- *
- * When we exit the loop, we unlock the node, then check the `error'
- * variable. If it is non-zero, this means that the cache was
- * completely flushed and that no usable memory was found to load
- * the bitmap.
- *
- * We then prefer to return a value of 0 (i.e., NO MATCH). This
- * ensures that the caller will try to allocate a new node.
- * This operation consequently _fail_ and the lookup function
- * returns the appropriate OOM error code.
- *
- * Note that `buffer == NULL && width == 255' is a hack used to
- * tag `unavailable' bitmaps in the array. We should never try
- * to load these.

- * A poor-man error facility.

- * Java. Instead, we are stuck with using error codes that must be
- * carefully managed and preserved. However, it is convenient for us to
- * model our error mechanism on a Java-like exception mechanism.
- * When we assign an error code we are thus `throwing' an error.
- *
- * The preservation of an error code is done by coding convention.
- * Upon a function call if the error code is anything other than
- * `FT_Err_Ok', which is guaranteed to be zero, we
- * will return without altering that error. This will allow the
- * error to propagate and be handled at the appropriate location in
- * the code.
- *
- * This allows a style of code where the error code is initialized
- * up front and a block of calls are made with the error code only
- * being checked after the block. If a new error occurs, the original
- * error will be preserved and a functional no-op should result in any
- * subsequent function that has an initial error code not equal to
- * `FT_Err_Ok'.
- *
- * Errors are encoded by calling the `FT_THROW' macro. For example,
- *
- * {
- * FT_Error e;

-gxvalid: TrueType GX validator
-==============================
-
-
-1. What is this
----------------
-
- `gxvalid' is a module to validate TrueType GX tables: a collection of
- additional tables in TrueType font which are used by `QuickDraw GX
- Text', Apple Advanced Typography (AAT). In addition, gxvalid can
- validates `kern' tables which have been extended for AAT. Like the
- otvalid module, gxvalid uses Freetype 2's validator framework
- (ftvalid).
-
- You can link gxvalid with your program; before running your own layout
- engine, gxvalid validates a font file. As the result, you can remove
- error-checking code from the layout engine. It is also possible to
- use gxvalid as a stand-alone font validator; the `ftvalid' test
- program included in the ft2demo bundle calls gxvalid internally.
- A stand-alone font validator may be useful for font developers.
-
- This documents documents the following issues.
-
- - supported TrueType GX tables
- - fundamental validation limitations
- - permissive error handling of broken GX tables
- - `kern' table issue.
-
-
-2. Supported tables
--------------------
-
- The following GX tables are currently supported.
-
- bsln
- feat
- just
- kern(*)
- lcar
- mort
- morx
- opbd
- prop
- trak
-
- The following GX tables are currently unsupported.
-
- cvar
- fdsc
- fmtx
- fvar
- gvar
- Zapf
-
- The following GX tables won't be supported.
-
- acnt(**)
- hsty(***)
-
- The following undocumented tables in TrueType fonts designed for Apple
- platform aren't handled either.
-
- addg
- CVTM
- TPNM
- umif
-
-
- *) The `kern' validator handles both the classic and the new kern
- formats; the former is supported on both Microsoft and Apple
- platforms, while the latter is supported on Apple platforms.
-
- **) `acnt' tables are not supported by currently available Apple font
- tools.
-
- ***) There is one more Apple extension, `hsty', but it is for
- Newton-OS, not GX (Newton-OS is a platform by Apple, but it can
- use sfnt- housed bitmap fonts only). Therefore, it should be
- excluded from `Apple platform' in the context of TrueType.
- gxvalid ignores it as Apple font tools do so.
-
-
- We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition,
- we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh
- fonts (designed for Windows and MacOS dual platforms). The number of
- fonts including TrueType GX tables are as follows.
-
- bsln: 76
- feat: 191
- just: 84
- kern: 59
- lcar: 4
- mort: 326
- morx: 19
- opbd: 4
- prop: 114
- trak: 16
-
- Dynalab and Ricoh fonts don't have GX tables except of `feat' and
- `mort'.
-
-
-3. Fundamental validation limitations
--------------------------------------
-
- TrueType GX provides layout information to libraries for font
- rasterizers and text layout. gxvalid can check whether the layout
- data in a font is conformant to the TrueType GX format specified by
- Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses
- the stored information.
-
- 3-1. Validation of State Machine activity
- -----------------------------------------
-
- QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
- features, and TrueType GX stores the state transition diagram of
- this `State Machine' in a `StateTable' data structure. While the
- State Machine receives a series of glyph IDs, the State Machine
- starts with `start of text' state, walks around various states and
- generates various layout information to the renderer, and finally
- reaches the `end of text' state.
-
- gxvalid can check essential errors like:
-
- - possibility of state transitions to undefined states
- - existence of glyph IDs that the State Machine doesn't know how
- to handle
- - the State Machine cannot compute the layout information from
- given diagram
-
- These errors can be checked within finite steps, and without the
- State Machine itself, because these are `expression' errors of state
- transition diagram.
-
- There is no limitation about how long the State Machine walks
- around, so validation of the algorithm in the state transition
- diagram requires infinite steps, even if we had a State Machine in
- gxvalid. Therefore, the following errors and problems cannot be
- checked.
-
- - existence of states which the State Machine never transits to
- - the possibility that the State Machine never reaches `end of
- text'
- - the possibility of stack underflow/overflow in the State Machine
- (in ligature and contextual glyph substitutions, the State
- Machine can store 16 glyphs onto its stack)
-
- In addition, gxvalid doesn't check `temporary glyph IDs' used in the
- chained State Machines (in `mort' and `morx' tables). If a layout
- feature is implemented by a single State Machine, a glyph ID
- converted by the State Machine is passed to the glyph renderer, thus
- it should not point to an undefined glyph ID. But if a layout
- feature is implemented by chained State Machines, a component State
- Machine (if it is not the final one) is permitted to generate
- undefined glyph IDs for temporary use, because it is handled by next
- component State Machine and not by the glyph renderer. To validate
- such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
- which can occur in the output of the previous State Machine and
- search them in the `ClassTable' structure of the current State
- Machine. It is too complex to list all possible glyph IDs from the
- StateTable, especially from a ligature substitution table.
-
- 3-2. Validation of relationship between multiple layout features
- ----------------------------------------------------------------
-
- gxvalid does not validate the relationship between multiple layout
- features at all.
-
- If multiple layout features are defined in TrueType GX tables,
- possible interactions, overrides, and conflicts between layout
- features are implicitly given in the font too. For example, there
- are several predefined spacing control features:
-
- - Text Spacing (Proportional/Monospace/Half-width/Normal)
- - Number Spacing (Monospaced-numbers/Proportional-numbers)
- - Kana Spacing (Full-width/Proportional)
- - Ideographic Spacing (Full-width/Proportional)
- - CJK Roman Spacing (Half-width/Proportional/Default-roman
- /Full-width-roman/Proportional)
-
- If all layout features are independently managed, we can activate
- inconsistent typographic rules like `Text Spacing=Monospace' and
- `Ideographic Spacing=Proportional' at the same time.
-
- The combinations of layout features is managed by a 32bit integer
- (one bit each for selector setting), so we can define relationships
- between up to 32 features, theoretically. But if one feature
- setting affects another feature setting, we need typographic
- priority rules to validate the relationship. Unfortunately, the
- TrueType GX format specification does not give such information even
- for predefined features.
-
-
-4. Permissive error handling of broken GX tables
-------------------------------------------------
-
- When Apple's font rendering system finds an inconsistency, like a
- specification violation or an unspecified value in a TrueType GX
- table, it does not always return error. In most cases, the rendering
- engine silently ignores such wrong values or even whole tables. In
- fact, MacOS is shipped with fonts including broken GX/AAT tables, but
- no harmful effects due to `officially broken' fonts are observed by
- end-users.
-
- gxvalid is designed to continue the validation process as long as
- possible. When gxvalid find wrong values, gxvalid warns it at least,
- and takes a fallback procedure if possible. The fallback procedure
- depends on the debug level.
-
- We used the following three tools to investigate Apple's error handling.
-
- - FontValidator (for MacOS 8.5 - 9.2) resource fork font
- - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt
- - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt
-
- However, all tests were done on a PowerPC based Macintosh; at present,
- we have not checked those tools on a m68k-based Macintosh.
-
- In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS
- 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts
- are distributed officially, but many broken GX/AAT tables were found
- by Apple's font tools. In the following, we list typical violation of
- the GX specification, in fonts officially distributed with those Apple
- systems.
-
- 4-1. broken BinSrchHeader (19/183)
- ----------------------------------
-
- `BinSrchHeader' is a header of a data array for m68k platforms to
- access memory efficiently. Although there are only two independent
- parameters for real (`unitSize' and `nUnits'), BinSrchHeader has
- three additional parameters which can be calculated from `unitSize'
- and `nUnits', for fast setup. Apple font tools ignore them
- silently, so gxvalid warns if it finds and inconsistency, and always
- continues validation. The additional parameters are ignored
- regardless of the consistency.
-
- 19 fonts include such inconsistencies; all breaks are in the
- BinSrchHeader structure of the `kern' table.
-
- 4-2. too-short LookupTable (5/183)
- ----------------------------------
-
- LookupTable format 0 is a simple array to get a value from a given
- GID (glyph ID); the index of this array is a GID too. Therefore,
- the length of the array is expected to be same as the maximum GID
- value defined in the `maxp' table, but there are some fonts whose
- LookupTable format 0 is too short to cover all GIDs. FontValidator
- ignores this error silently, ftxvalidator and ftxdumperfuser both
- warn and continue. Similar problems are found in format 3 subtables
- of `kern'. gxvalid warns always and abort if the validation level
- is set to FT_VALIDATE_PARANOID.
-
- 5 fonts include too-short kern format 0 subtables.
- 1 font includes too-short kern format 3 subtable.
-
- 4-3. broken LookupTable format 2 (1/183)
- ----------------------------------------
-
- LookupTable format 2, subformat 4 covers the GID space by a
- collection of segments which are specified by `firstGlyph' and
- `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in
- reverse order, so the segment specification is broken. Apple font
- tools ignore this error silently; a broken segment is ignored as if
- it did not exist. gxvalid warns and normalize the segment at
- FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or
- abort at FT_VALIDATE_PARANOID.
-
- 1 font includes broken LookupTable format 2, in the `just' table.
-
- *) It seems that all fonts manufactured by ITC for AppleWorks have
- this error.
-
- 4-4. bad bracketing in glyph property (14/183)
- ----------------------------------------------
-
- GX/AAT defines a `bracketing' property of the glyphs in the `prop'
- table, to control layout features of strings enclosed inside and
- outside of brackets. Some fonts give inappropriate bracket
- properties to glyphs. Apple font tools warn about this error;
- gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
-
- 14 fonts include wrong bracket properties.
-
-
- 4-5. invalid feature number (117/183)
- -------------------------------------
-
- The GX/AAT extension can include 255 different layout features, but
- popular layout features are predefined (see
- http://developer.apple.com/fonts/Registry/index.html). Some fonts
- include feature numbers which are incompatible with the predefined
- feature registry.
-
- In our survey, there are 140 fonts including `feat' table.
-
- a) 67 fonts use a feature number which should not be used.
- b) 117 fonts set the wrong feature range (nSetting). This is mostly
- found in the `mort' and `morx' tables.
-
- Apple font tools give no warning, although they cannot recognize
- what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but
- continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns
- and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID,
- gxvalid warns and aborts in both cases (a, b).
-
- 4-6. invalid prop version (10/183)
- ----------------------------------
-
- As most TrueType GX tables, the `prop' table must start with a 32bit
- version identifier: 0x00010000, 0x00020000 or 0x00030000. But some
- fonts store nonsense binary data instead. When Apple font tools
- find them, they abort the processing immediately, and the data which
- follows is unhandled. gxvalid does the same.
-
- 10 fonts include broken `prop' version.
-
- All of these fonts are classic TrueType fonts for the Japanese
- script, manufactured by Apple.
-
- 4-7. unknown resource name (2/183)
- ------------------------------------
-
- NOTE: THIS IS NOT A TRUETYPE GX ERROR.
-
- If a TrueType font is stored in the resource fork or in dfont
- format, the data must be tagged as `sfnt' in the resource fork index
- to invoke TrueType font handler for the data. But the TrueType font
- data in `Keyboard.dfont' is tagged as `kbd', and that in
- `LastResort.dfont' is tagged as `lst'. Apple font tools can detect
- that the data is in TrueType format and successfully validate them.
- Maybe this is possible because they are known to be dfont. The
- current implementation of the resource fork driver of FreeType
- cannot do that, thus gxvalid cannot validate them.
-
- 2 fonts use an unknown tag for the TrueType font resource.
-
-5. `kern' table issues
-----------------------
-
- In common terminology of TrueType, `kern' is classified as a basic and
- platform-independent table. But there are Apple extensions of `kern',
- and there is an extension which requires a GX state machine for
- contextual kerning. Therefore, gxvalid includes a special validator
- for `kern' tables. Unfortunately, there is no exact algorithm to
- check Apple's extension, so gxvalid includes a heuristic algorithm to
- find the proper validation routines for all possible data formats,
- including the data format for Microsoft. By calling
- classic_kern_validate() instead of gxv_validate(), you can specify the
- `kern' format explicitly. However, current FreeType2 uses Microsoft
- `kern' format only, others are ignored (and should be handled in a
- library one level higher than FreeType).
-
- 5-1. History
- ------------
-
- The original 16bit version of `kern' was designed by Apple in the
- pre-GX era, and it was also approved by Microsoft. Afterwards,
- Apple designed a new 32bit version of the `kern' table. According
- to the documentation, the difference between the 16bit and 32bit
- version is only the size of variables in the `kern' header. In the
- following, we call the original 16bit version as `classic', and
- 32bit version as `new'.
-
- 5-2. Versions and dialects which should be differentiated
- ---------------------------------------------------------
-
- The `kern' table consists of a table header and several subtables.
- The version number which identifies a `classic' or a `new' version
- is explicitly written in the table header, but there are
- undocumented differences between Microsoft's and Apple's formats.
- It is called a `dialect' in the following. There are three cases
- which should be handled: the new Apple-dialect, the classic
- Apple-dialect, and the classic Microsoft-dialect. An analysis of
- the formats and the auto detection algorithm of gxvalid is described
- in the following.
-
- 5-2-1. Version detection: classic and new kern
- ----------------------------------------------
-
- According to Apple TrueType specification, there are only two
- differences between the classic and the new:
-
- - The `kern' table header starts with the version number.
- The classic version starts with 0x0000 (16bit),
- the new version starts with 0x00010000 (32bit).
-
- - In the `kern' table header, the number of subtables follows
- the version number.
- In the classic version, it is stored as a 16bit value.
- In the new version, it is stored as a 32bit value.
-
- From Apple font tool's output (DumpKERN is also tested in addition
- to the three Apple font tools in above), there is another
- undocumented difference. In the new version, the subtable header
- includes a 16bit variable named `tupleIndex' which does not exist
- in the classic version.
-
- The new version can store all subtable formats (0, 1, 2, and 3),
- but the Apple TrueType specification does not mention the subtable
- formats available in the classic version.
-
- 5-2-2. Available subtable formats in classic version
- ----------------------------------------------------
-
- Although the Apple TrueType specification recommends to use the
- classic version in the case if the font is designed for both the
- Apple and Microsoft platforms, it does not document the available
- subtable formats in the classic version.
-
- According to the Microsoft TrueType specification, the subtable
- format assured for Windows and OS/2 support is only subtable
- format 0. The Microsoft TrueType specification also describes
- subtable format 2, but does not mention which platforms support
- it. Subtable formats 1, 3, and higher are documented as reserved
- for future use. Therefore, the classic version can store subtable
- formats 0 and 2, at least. `ttfdump.exe', a font tool provided by
- Microsoft, ignores the subtable format written in the subtable
- header, and parses the table as if all subtables are in format 0.
-
- `kern' subtable format 1 uses a StateTable, so it cannot be
- utilized without a GX State Machine. Therefore, it is reasonable
- to assume that format 1 (and 3) were introduced after Apple had
- introduced GX and moved to the new 32bit version.
-
- 5-2-3. Apple and Microsoft dialects
- -----------------------------------
-
- The `kern' subtable has a 16bit `coverage' field to describe
- kerning attributes, but bit interpretations by Apple and Microsoft
- are different: For example, Apple uses bits 0-7 to identify the
- subtable, while Microsoft uses bits 8-15.
-
- In addition, due to the output of DumpKERN and FontValidator,
- Apple's bit interpretations of coverage in classic and new version
- are incompatible also. In summary, there are three dialects:
- classic Apple dialect, classic Microsoft dialect, and new Apple
- dialect. The classic Microsoft dialect and the new Apple dialect
- are documented by each vendors' TrueType font specification, but
- the documentation for classic Apple dialect is not available.
-
- For example, in the new Apple dialect, bit 15 is documented as
- `set to 1 if the kerning is vertical'. On the other hand, in
- classic Microsoft dialect, bit 1 is documented as `set to 1 if the
- kerning is horizontal'. From the outputs of DumpKERN and
- FontValidator, classic Apple dialect recognizes 15 as `set to 1
- when the kerning is horizontal'. From the results of similar
- experiments, classic Apple dialect seems to be the Endian reverse
- of the classic Microsoft dialect.
-
- As a conclusion it must be noted that no font tool can identify
- classic Apple dialect or classic Microsoft dialect automatically.
-
- 5-2-4. gxvalid auto dialect detection algorithm
- -----------------------------------------------
-
- The first 16 bits of the `kern' table are enough to identify the
- version:
-
- - if the first 16 bits are 0x0000, the `kern' table is in
- classic Apple dialect or classic Microsoft dialect
- - if the first 16 bits are 0x0001, and next 16 bits are 0x0000,
- the kern table is in new Apple dialect.
-
- If the `kern' table is a classic one, the 16bit `coverage' field
- is checked next. Firstly, the coverage bits are decoded for the
- classic Apple dialect using the following bit masks (this is based
- on DumpKERN output):
-
- 0x8000: 1=horizontal, 0=vertical
- 0x4000: not used
- 0x2000: 1=cross-stream, 0=normal
- 0x1FF0: reserved
- 0x000F: subtable format
-
- If any of reserved bits are set or the subtable bits is
- interpreted as format 1 or 3, we take it as `impossible in classic
- Apple dialect' and retry, using the classic Microsoft dialect.
-
- The most popular coverage in new Apple-dialect: 0x8000,
- The most popular coverage in classic Apple-dialect: 0x0000,
- The most popular coverage in classic Microsoft dialect: 0x0001.
-
- 5-3. Tested fonts
- -----------------
-
- We checked 59 fonts bundled with MacOS and 38 fonts bundled with
- Windows, where all font include a `kern' table.
-
- - fonts bundled with MacOS
- * new Apple dialect
- format 0: 18
- format 2: 1
- format 3: 1
- * classic Apple dialect
- format 0: 14
- * classic Microsoft dialect
- format 0: 15
-
- - fonts bundled with Windows
- * classic Microsoft dialect
- format 0: 38
-
- It looks strange that classic Microsoft-dialect fonts are bundled to
- MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.
-
-
- ACKNOWLEDGEMENT
- ---------------
-
- Some parts of gxvalid are derived from both the `gxlayout' module and
- the `otvalid' module. Development of gxlayout was supported by the
- Information-technology Promotion Agency(IPA), Japan.
-
- The detailed analysis of undefined glyph ID utilization in `mort' and
- `morx' tables is provided by George Williams.

- Notes beyond the 1.93a appnote.txt:
-
- 1. Distance pointers never point before the beginning of the output
- stream.
- 2. Distance pointers can point back across blocks, up to 32k away.
- 3. There is an implied maximum of 7 bits for the bit length table and
- 15 bits for the actual data.
- 4. If only one code exists, then it is encoded using one bit. (Zero
- would be more efficient, but perhaps a little confusing.) If two
- codes exist, they are coded using one bit each (0 and 1).
- 5. There is no way of sending zero distance codes--a dummy must be
- sent if there are none. (History: a pre 2.0 version of PKZIP would
- store blocks with no distance codes, but this was discovered to be
- too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
- zero distance codes, which is sent as one code of zero bits in
- length.
- 6. There are up to 286 literal/length codes. Code 256 represents the
- end-of-block. Note however that the static length tree defines
- 288 codes just to fill out the Huffman codes. Codes 286 and 287
- cannot be used though, since there is no length base or extra bits
- defined for them. Similarily, there are up to 30 distance codes.
- However, static trees define 32 codes (all 5 bits) to fill out the
- Huffman codes, but the last two had better not show up in the data.
- 7. Unzip can check dynamic Huffman blocks for complete code sets.
- The exception is that a single code would not be complete (see #4).
- 8. The five bits following the block type is really the number of
- literal codes sent minus 257.
- 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
- (1+6+6). Therefore, to output three times the length, you output
- three codes (1+1+1), whereas to output four times the same length,
- you only need two codes (1+3). Hmm.
- 10. In the tree reconstruction algorithm, Code = Code + Increment
- only if BitLength(i) is not zero. (Pretty obvious.)
- 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
- 12. Note: length code 284 can represent 227-258, but length code 285
- really is 258. The last length deserves its own, short code
- since it gets used a lot in very redundant files. The length
- 258 is special since 258 - 3 (the min match length) is 255.
- 13. The literal/length and distance code bit lengths are read as a
- single stream of lengths. It is possible (and advantageous) for
- a repeat code (16, 17, or 18) to go across the boundary between
- the two sets of lengths.

- Huffman code decoding is performed using a multi-level table lookup.
- The fastest way to decode is to simply build a lookup table whose
- size is determined by the longest code. However, the time it takes
- to build this table can also be a factor if the data being decoded
- is not very long. The most common codes are necessarily the
- shortest codes, so those codes dominate the decoding time, and hence
- the speed. The idea is you can have a shorter table that decodes the
- shorter, more probable codes, and then point to subsidiary tables for
- the longer codes. The time it costs to decode the longer codes is
- then traded against the time it takes to make longer tables.
-
- This results of this trade are in the variables lbits and dbits
- below. lbits is the number of bits the first level table for literal/
- length codes can decode in one step, and dbits is the same thing for
- the distance codes. Subsequent tables are also less than or equal to
- those sizes. These values may be adjusted either when all of the
- codes are shorter than that, in which case the longest code length in
- bits is used, or when the shortest code is *longer* than the requested
- table size, in which case the length of the shortest code in bits is
- used.
-
- There are two different values for the two tables, since they code a
- different number of possibilities each. The literal/length table
- codes 286 possible values, or in a flat code, a little over eight
- bits. The distance table codes 30 possible values, or a little less
- than five bits, flat. The optimum values for speed end up being
- about one bit more than those, so lbits is 8+1 and dbits is 5+1.
- The optimum values may differ though from machine to machine, and
- possibly even between compilers. Your mileage may vary.

- (deflation) but other algorithms will be added later and will have the same

-
- Compression can be done in a single step if the buffers are large
- enough (for example if an input file is mmap'ed), or can be done by
- repeated calls of the compression function. In the latter case, the
- application must provide more input and/or consume the output
- (providing more output space) before each call.
-
- The library also supports reading and writing files in gzip (.gz) format
- with an interface similar to that of stdio.
-
- The library does not install any signal handler. The decoder checks
- the consistency of the compressed data, so the library should never
- crash even in case of corrupted input.

-
-/*
- deflate compresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may introduce some
- output latency (reading input without producing any output) except when
- forced to flush.
-
- The detailed semantics are as follows. deflate performs one or both of the
- following actions:
-
- - Compress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in and avail_in are updated and
- processing will resume at this point for the next call of deflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. This action is forced if the parameter flush is non zero.
- Forcing flush frequently degrades the compression ratio, so this parameter
- should be set only when necessary (in interactive applications).
- Some output may be provided even if flush is not set.
-
- Before the call of deflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming
- more output, and updating avail_in or avail_out accordingly; avail_out
- should never be zero before the call. The application can consume the
- compressed output when it wants, for example when the output buffer is full
- (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
- and with zero avail_out, it must be called again after making room in the
- output buffer because there might be more output pending.
-
- If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
- flushed to the output buffer and the output is aligned on a byte boundary, so
- that the decompressor can get all input data available so far. (In particular
- avail_in is zero after the call if enough output space has been provided
- before the call.) Flushing may degrade compression for some compression
- algorithms and so it should be used only when necessary.
-
- If flush is set to Z_FULL_FLUSH, all output is flushed as with
- Z_SYNC_FLUSH, and the compression state is reset so that decompression can
- restart from this point if previous compressed data has been damaged or if
- random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
- the compression.
-
- If deflate returns with avail_out == 0, this function must be called again
- with the same value of the flush parameter and more output space (updated
- avail_out), until the flush is complete (deflate returns with non-zero
- avail_out).
-
- If the parameter flush is set to Z_FINISH, pending input is processed,
- pending output is flushed and deflate returns with Z_STREAM_END if there
- was enough output space; if deflate returns with Z_OK, this function must be
- called again with Z_FINISH and more output space (updated avail_out) but no
- more input data, until it returns with Z_STREAM_END or an error. After
- deflate has returned Z_STREAM_END, the only possible operations on the
- stream are deflateReset or deflateEnd.
-
- Z_FINISH can be used immediately after deflateInit if all the compression
- is to be done in a single step. In this case, avail_out must be at least
- 0.1% larger than avail_in plus 12 bytes. If deflate does not return
- Z_STREAM_END, then it must be called again as described above.
-
- deflate() sets strm->adler to the adler32 checksum of all input read
- so far (that is, total_in bytes).
-
- deflate() may update data_type if it can make a good guess about
- the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
- binary. This field is only for information purposes and does not affect
- the compression algorithm in any manner.
-
- deflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if all input has been
- consumed and all output has been produced (only when flush is set to
- Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
- if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
- (for example avail_in or avail_out was zero).
-*/
-
-
-/*
- All dynamically allocated data structures for this stream are freed.

-ZEXTERN(int) inflate OF((z_streamp strm, int flush));
-/*
- inflate decompresses as much data as possible, and stops when the input
- buffer becomes empty or the output buffer becomes full. It may some
- introduce some output latency (reading input without producing any output)
- except when forced to flush.
-
- The detailed semantics are as follows. inflate performs one or both of the
- following actions:
-
- - Decompress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in is updated and processing
- will resume at this point for the next call of inflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() provides as much output as possible, until there
- is no more input data or no more space in the output buffer (see below
- about the flush parameter).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming
- more output, and updating the next_* and avail_* values accordingly.
- The application can consume the uncompressed output when it wants, for
- example when the output buffer is full (avail_out == 0), or after each
- call of inflate(). If inflate returns Z_OK and with zero avail_out, it
- must be called again after making room in the output buffer because there
- might be more output pending.
-
- If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
- output as possible to the output buffer. The flushing behavior of inflate is
- not specified for values of the flush parameter other than Z_SYNC_FLUSH
- and Z_FINISH, but the current implementation actually flushes as much output
- as possible anyway.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step
- (a single call of inflate), the parameter flush should be set to
- Z_FINISH. In this case all pending input is processed and all pending
- output is flushed; avail_out must be large enough to hold all the
- uncompressed data. (The size of the uncompressed data may have been saved
- by the compressor for this purpose.) The next operation on this stream must
- be inflateEnd to deallocate the decompression state. The use of Z_FINISH
- is never required, but can be used to inform inflate that a faster routine
- may be used for the single inflate() call.
-
- If a preset dictionary is needed at this point (see inflateSetDictionary
- below), inflate sets strm-adler to the adler32 checksum of the
- dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
- it sets strm->adler to the adler32 checksum of all output produced
- so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
- an error code as described below. At the end of the stream, inflate()
- checks that its computed adler32 checksum is equal to that saved by the
- compressor and returns Z_STREAM_END only if the checksum is correct.
-
- inflate() returns Z_OK if some progress has been made (more input processed
- or more output produced), Z_STREAM_END if the end of the compressed data has
- been reached and all uncompressed output has been produced, Z_NEED_DICT if a
- preset dictionary is needed at this point, Z_DATA_ERROR if the input data was

-
- This is another version of deflateInit with more compression options. The
- fields next_in, zalloc, zfree and opaque must be initialized before by
- the caller.
-
- The method parameter is the compression method. It must be Z_DEFLATED in
- this version of the library.
-
- The windowBits parameter is the base two logarithm of the window size
- (the size of the history buffer). It should be in the range 8..15 for this
- version of the library. Larger values of this parameter result in better
- compression at the expense of memory usage. The default value is 15 if
- deflateInit is used instead.
-
- The memLevel parameter specifies how much memory should be allocated
- for the internal compression state. memLevel=1 uses minimum memory but
- is slow and reduces compression ratio; memLevel=9 uses maximum memory
- for optimal speed. The default value is 8. See zconf.h for total memory
- usage as a function of windowBits and memLevel.
-
- The strategy parameter is used to tune the compression algorithm. Use the
- value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
- filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
- string match). Filtered data consists mostly of small values with a
- somewhat random distribution. In this case, the compression algorithm is
- tuned to compress them better. The effect of Z_FILTERED is to force more
- Huffman coding and less string matching; it is somewhat intermediate
- between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
- the compression ratio but not the correctness of the compressed output even
- if it is not set appropriately.
-
- deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

- Initializes the compression dictionary from the given byte sequence
- without producing any compressed output. This function must be called
- immediately after deflateInit, deflateInit2 or deflateReset, before any
- call of deflate. The compressor and decompressor must use exactly the same
- dictionary (see inflateSetDictionary).
-
- The dictionary should consist of strings (byte sequences) that are likely
- to be encountered later in the data to be compressed, with the most commonly
- used strings preferably put towards the end of the dictionary. Using a
- dictionary is most useful when the data to be compressed is short and can be
- predicted with good accuracy; the data can then be compressed better than
- with the default empty dictionary.
-
- Depending on the size of the compression data structures selected by
- deflateInit or deflateInit2, a part of the dictionary may in effect be
- discarded, for example if the dictionary is larger than the window size in
- deflate or deflate2. Thus the strings most likely to be useful should be
- put at the end of the dictionary, not at the front.
-
- Upon return of this function, strm->adler is set to the Adler32 value
- of the dictionary; the decompressor may later use this value to determine
- which dictionary has been used by the compressor. (The Adler32 value
- applies to the whole dictionary even if only a subset of the dictionary is
- actually used by the compressor.)

- by calling deflateEnd. Note that deflateCopy duplicates the internal
- compression state which can be quite large, so this strategy is slow and
- can consume lots of memory.

- * state of LZW decompressor
- *
- * small technical note
- * --------------------
- *
- * We use a few tricks in this implementation that are explained here to
- * ease debugging and maintenance.
- *
- * - First of all, the `prefix' and `suffix' arrays contain the suffix
- * and prefix for codes over 256; this means that
- *
- * prefix_of(code) == state->prefix[code-256]
- * suffix_of(code) == state->suffix[code-256]
- *
- * Each prefix is a 16-bit code, and each suffix an 8-bit byte.
- *
- * Both arrays are stored in a single memory block, pointed to by
- * `state->prefix'. This means that the following equality is always
- * true:
- *
- * state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
- *
- * Of course, state->prefix_size is the number of prefix/suffix slots
- * in the arrays, corresponding to codes 256..255+prefix_size.
- *
- * - `free_ent' is the index of the next free entry in the `prefix'
- * and `suffix' arrays. This means that the corresponding `next free
- * code' is really `256+free_ent'.
- *
- * Moreover, `max_free' is the maximum value that `free_ent' can reach.
- *
- * `max_free' corresponds to `(1 << max_bits) - 256'. Note that this
- * value is always <= 0xFF00, which means that both `free_ent' and
- * `max_free' can be stored in an FT_UInt variable, even on 16-bit
- * machines.
- *
- * If `free_ent == max_free', you cannot add new codes to the
- * prefix/suffix table.
- *
- * - `num_bits' is the current number of code bits, starting at 9 and
- * growing each time `free_ent' reaches the value of `free_bits'. The
- * latter is computed as follows
- *
- * if num_bits < max_bits:
- * free_bits = (1 << num_bits)-256
- * else:
- * free_bits = max_free + 1
- *
- * Since the value of `max_free + 1' can never be reached by
- * `free_ent', `num_bits' cannot grow larger than `max_bits'.

- FreeType font driver for PCF fonts

-Introduction
-************
-
-PCF (Portable Compiled Format) is a binary bitmap font format, largely used
-in X world. This code implements a PCF driver for the FreeType library.
-Glyph images are loaded into memory only on demand, thus leading to a small
-memory footprint.
-
-Information on the PCF font format can only be worked out from
-`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
-(www.xfree86.org) source tree (xc/lib/font/bitmap/).
-
-Many good bitmap fonts in bdf format come with XFree86: they can be
-compiled into the pcf format using the `bdftopcf' utility.
-
-
-Supported hardware
-******************
-
-The driver has been tested on linux/x86 and sunos5.5/sparc. In both
-cases the compiler was gcc. When back in Paris, I will test it also
-on linux/alpha.
-
-
-Encodings
-*********
-
-Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
-
-The driver always exports `ft_encoding_none' as face->charmap.encoding.
-FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong
-value given as argument into the corresponding glyph number.
-
-
-Known problems
-**************
-
-- dealing explicitly with encodings breaks the uniformity of freetype2
- api.
-
-- except for encodings properties, client applications have no
- visibility of the PCF_Face object. This means that applications
- cannot directly access font tables and are obliged to trust
- FreeType.
-
-- currently, glyph names and ink_metrics are ignored.
-
-I plan to give full visibility of the PCF_Face object in the next
-release of the driver, thus implementing also glyph names and
-ink_metrics.
-
-- height is defined as (ascent - descent). Is this correct?
-
-- if unable to read size information from the font, PCF_Init_Face
- sets available_size->width and available_size->height to 12.
-
-- too many english grammar errors in the readme file :-(

-Keith Packard wrote the pcf driver found in XFree86. His work is at
-the same time the specification and the sample implementation of the
-PCF format. Undoubtedly, this driver is inspired from his work.

- /* A simple technical note on how the raster works */
- /* ----------------------------------------------- */
- /* */
- /* Converting an outline into a bitmap is achieved in several steps: */
- /* */
- /* 1 - Decomposing the outline into successive `profiles'. Each */
- /* profile is simply an array of scanline intersections on a given */
- /* dimension. A profile's main attributes are */
- /* */
- /* o its scanline position boundaries, i.e. `Ymin' and `Ymax' */
- /* */
- /* o an array of intersection coordinates for each scanline */
- /* between `Ymin' and `Ymax' */
- /* */
- /* o a direction, indicating whether it was built going `up' or */
- /* `down', as this is very important for filling rules */
- /* */
- /* o its drop-out mode */
- /* */
- /* 2 - Sweeping the target map's scanlines in order to compute segment */
- /* `spans' which are then filled. Additionally, this pass */
- /* performs drop-out control. */
- /* */
- /* The outline data is parsed during step 1 only. The profiles are */
- /* built from the bottom of the render pool, used as a stack. The */
- /* following graphics shows the profile list under construction: */
- /* */
- /* __________________________________________________________ _ _ */
- /* | | | | | */
- /* | profile | coordinates for | profile | coordinates for |--> */
- /* | 1 | profile 1 | 2 | profile 2 |--> */
- /* |_________|_________________|_________|_________________|__ _ _ */
- /* */
- /* ^ ^ */
- /* | | */
- /* start of render pool top */
- /* */
- /* The top of the profile stack is kept in the `top' variable. */
- /* */
- /* As you can see, a profile record is pushed on top of the render */
- /* pool, which is then followed by its coordinates/intersections. If */
- /* a change of direction is detected in the outline, a new profile is */
- /* generated until the end of the outline. */
- /* */
- /* Note that when all profiles have been generated, the function */
- /* Finalize_Profile_Table() is used to record, for each profile, its */
- /* bottom-most scanline as well as the scanline above its upmost */
- /* boundary. These positions are called `y-turns' because they (sort */
- /* of) correspond to local extrema. They are stored in a sorted list */
- /* built from the top of the render pool as a downwards stack: */
- /* */
- /* _ _ _______________________________________ */
- /* | | */
- /* <--| sorted list of | */
- /* <--| extrema scanlines | */
- /* _ _ __________________|____________________| */
- /* */
- /* ^ ^ */
- /* | | */
- /* maxBuff sizeBuff = end of pool */
- /* */
- /* This list is later used during the sweep phase in order to */
- /* optimize performance (see technical note on the sweep below). */
- /* */
- /* Of course, the raster detects whether the two stacks collide and */
- /* handles the situation properly. */

-
-ftfuzzer.cc
------------
-
-This file contains a target function for FreeType fuzzing. It can be
-used with libFuzzer (http://llvm.org/docs/LibFuzzer.html) or
-potentially any other similar fuzzer.
-
-Usage:
-
- 1. Build `libfreetype.a' and `ftfuzzer.cc' using the most recent
- clang compiler with these flags:
-
- # for fuzzer coverage feedback
- -fsanitize-coverage=edge,8bit-counters
- # for bug checking
- -fsanitize=address,signed-integer-overflow,shift
-
- You also need the header files from the `libarchive' library
- (http://www.libarchive.org/) for handling tar files (see file
- `ftmutator.cc' below for more).
-
- 2. Link with `libFuzzer' (it contains `main') and `libarchive'.
-
- 3. Run the fuzzer on some test corpus.
-
-The exact flags and commands may vary.
-
-
-There is a continuous fuzzing bot that runs ftfuzzer.
-
- https://github.com/google/libfuzzer-bot/tree/master/freetype
-
-Check the bot configuration for the most current settings.
-
-
-ftmutator.cc
-------------
-
-FreeType has the ability to `attach' auxiliary files to a font file,
-providing additional information. The main usage is to load AFM files
-for PostScript Type 1 fonts.
-
-However, libFuzzer currently only supports mutation of a single input
-file. For this reason, `ftmutator.cc' contains a custom fuzzer
-mutator that uses an uncompressed tar file archive as the input. The
-first file in such a tarball gets opened by FreeType as a font, all
-other files are treated as input for `FT_Attach_Stream'.
-
-Compilation is similar to `ftfuzzer.c'.
-
-
-runinput.cc
------------
-
-To run the target function on a set of input files, this file contains
-a convenience `main' function. Link it with `ftfuzzer.cc',
-`libfreetype.a', and `libarchive' and run like
-
- ./a.out my_tests_inputs/*

-ftrandom
-========
-
-This program expects a set of directories containing good fonts, and a set
-of extensions of fonts to be tested. It will randomly pick a font, copy it,
-introduce an error and then test it.
-
-The FreeType tests are quite basic; for each erroneous font ftrandom
-
- . forks off a new tester,
- . initializes the library,
- . opens each font in the file,
- . loads each glyph,
- . optionally reviews the contours of the glyph,
- . optionally rasterizes the glyph, and
- . closes the face.
-
-If a tester takes longer than 20 seconds, ftrandom saves the erroneous font
-and continues. If the tester exits normally or with an error, then the
-superstructure removes the test font and continues.
-
-
-Command line options
---------------------
-
- --all Test every font in the directory(ies) no matter
- what its extension.
- --check-outlines Call `FT_Outline_Decompose' on each glyph.
- --dir <dir> Append <dir> to the list of directories to search
- for good fonts. No recursive search.
- --error-count <cnt> Introduce <cnt> single-byte errors into the
- erroneous fonts (default: 1).
- --error-fraction <frac> Multiply the file size of the font by <frac> and
- introduce that many errors into the erroneous
- font file. <frac> should be in the range [0;1]
- (default: 0.0).
- --ext <ext> Add <ext> to the set of font types tested.
- --help Print out this list of options.
- --nohints Specify FT_LOAD_NO_HINTING when loading glyphs.
- --rasterize Call `FT_Render_Glyph' as well as loading it.
- --result <dir> This is the directory in which test files are
- placed.
- --test <file> Run a single test on a pre-generated testcase.
- This is done in the current process so it can be
- debugged more easily.
-
-The default font extensions tested by ftrandom are
-
- .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
-
-The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
-the source code (and can be thus specified during compilation); its default
-value is
-
- /usr/local/share/fonts
-
-The default result directory is `results' (in the current directory).
-
-
-Compilation
------------
-
-Two possible solutions.
-
-. Run ftrandom within a debugging tool like `valgrind' to catch various
- memory issues.
-
-. Compile FreeType with sanitizer flags as provided by gcc or clang, for
- example, then link it with ftrandom.

-# We now store the Adobe Glyph List in compressed form. The list is put
-# into a data structure called `trie' (because it has a tree-like
-# appearance). Consider, for example, that you want to store the
-# following name mapping:
-#
-# A => 1
-# Aacute => 6
-# Abalon => 2
-# Abstract => 4
-#
-# It is possible to store the entries as follows.
-#
-# A => 1
-# |
-# +-acute => 6
-# |
-# +-b
-# |
-# +-alon => 2
-# |
-# +-stract => 4
-#
-# We see that each node in the trie has:
-#
-# - one or more `letters'
-# - an optional value
-# - zero or more child nodes
-#
-# The first step is to call
-#
-# root = StringNode( "", 0 )
-# for word in map.values():
-# root.add( word, map[word] )
-#
-# which creates a large trie where each node has only one children.
-#
-# Executing
-#
-# root = root.optimize()
-#
-# optimizes the trie by merging the letters of successive nodes whenever
-# possible.
-#
-# Each node of the trie is stored as follows.
-#
-# - First the node's letter, according to the following scheme. We
-# use the fact that in the AGL no name contains character codes > 127.
-#
-# name bitsize description
-# ----------------------------------------------------------------
-# notlast 1 Set to 1 if this is not the last letter
-# in the word.
-# ascii 7 The letter's ASCII value.

- * Calculate the phantom points
- *
- * Defining the right side bearing (rsb) as
- *
- * rsb = aw - (lsb + xmax - xmin)
- *
- * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
- * and `xmax' the glyph's minimum and maximum x value), the OpenType
- * specification defines the initial position of horizontal phantom points
- * as
- *
- * pp1 = (round(xmin - lsb), 0) ,
- * pp2 = (round(pp1 + aw), 0) .
- *
- * Note that the rounding to the grid (in the device space) is not
- * documented currently in the specification.
- *
- * However, the specification lacks the precise definition of vertical
- * phantom points. Greg Hitchcock provided the following explanation.
- *
- * - a `vmtx' table is present
- *
- * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
- * are given in the `glyf' table, the top side bearing (tsb) and advance
- * height (ah) are given in the `vmtx' table. The bottom side bearing
- * (bsb) is then calculated as
- *
- * bsb = ah - (tsb + ymax - ymin) ,
- *
- * and the initial position of vertical phantom points is
- *
- * pp3 = (x, round(ymax + tsb)) ,
- * pp4 = (x, round(pp3 - ah)) .
- *
- * See below for value `x'.
- *
- * - no `vmtx' table in the font
- *
- * If there is an `OS/2' table, we set
- *
- * DefaultAscender = sTypoAscender ,
- * DefaultDescender = sTypoDescender ,
- *
- * otherwise we use data from the `hhea' table:
- *
- * DefaultAscender = Ascender ,
- * DefaultDescender = Descender .
- *
- * With these two variables we can now set
- *
- * ah = DefaultAscender - sDefaultDescender ,
- * tsb = DefaultAscender - yMax ,
- *
- * and proceed as if a `vmtx' table was present.
- *
- * Usually we have
- *
- * x = aw / 2 , (1)
- *
- * but there is one compatibility case where it can be set to
- *
- * x = -DefaultDescender -
- * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
- *
- * and another one with
- *
- * x = 0 . (3)
- *
- * In Windows, the history of those values is quite complicated,
- * depending on the hinting engine (that is, the graphics framework).
- *
- * framework from to formula
- * ----------------------------------------------------------
- * GDI Windows 98 current (1)
- * (Windows 2000 for NT)
- * GDI+ Windows XP Windows 7 (2)
- * GDI+ Windows 8 current (3)
- * DWrite Windows 7 current (3)
- *
- * For simplicity, FreeType uses (1) for grayscale subpixel hinting and
- * (3) for everything else.

- /*
- * FreeType supports ClearType-like hinting of TrueType fonts through
- * the version 40 interpreter. This is achieved through several hacks
- * in the base (v35) interpreter, as detailed below.
- *
- * ClearType is an umbrella term for several rendering techniques
- * employed by Microsoft's various GUI and rendering toolkit
- * implementations, most importantly: subpixel rendering for using the
- * RGB subpixels of LCDs to approximately triple the perceived
- * resolution on the x-axis and subpixel hinting for positioning stems
- * on subpixel borders. TrueType programming is explicit, i.e., fonts
- * must be programmed to take advantage of ClearType's possibilities.
- *
- * When ClearType was introduced, it seemed unlikely that all fonts
- * would be reprogrammed, so Microsoft decided to implement a backward
- * compatibility mode. It employs several simple to complicated
- * assumptions and tricks, many of them font-dependent, that modify the
- * interpretation of the bytecode contained in these fonts to retrofit
- * them into a ClearType-y look. The quality of the results varies.
- * Most (web)fonts that were released since then have come to rely on
- * these hacks to render correctly, even some of Microsoft's flagship
- * fonts (e.g., Calibri, Cambria, Segoe UI).
- *
- * FreeType's minimal subpixel hinting code (interpreter version 40)
- * employs a small list of font-agnostic hacks loosely based on the
- * public information available on Microsoft's compatibility mode[2].
- * The focus is on modern (web)fonts rather than legacy fonts that were
- * made for monochrome rendering. It will not match ClearType rendering
- * exactly. Unlike the `Infinality' code (interpreter version 38) that
- * came before, it will not try to toggle hacks for specific fonts for
- * performance and complexity reasons. It will fall back to version 35
- * behavior for tricky fonts[1] or when monochrome rendering is
- * requested.
- *
- * Major hacks
- *
- * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
- * `Direct_Move_X'). This has the smallest code footprint and single
- * biggest effect. The ClearType way to increase resolution is
- * supersampling the x axis, the FreeType way is ignoring instructions
- * on the x axis, which gives the same result in the majority of
- * cases.
- *
- * - Points are not moved post-IUP (neither on the x nor on the y axis),
- * except the x component of diagonal moves post-IUP (cf.
- * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
- * changes are commonly used to `fix' pixel patterns which has little
- * use outside monochrome rendering.
- *
- * - SHPIX and DELTAP don't execute unless moving a composite on the
- * y axis or moving a previously y touched point. SHPIX additionally
- * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
- * Both instructions are commonly used to `fix' pixel patterns for
- * monochrome or Windows's GDI rendering but make little sense for
- * FreeType rendering. Both can distort the outline. See [2] for
- * details.
- *
- * - The hdmx table and modifications to phantom points are ignored.
- * Bearings and advance widths remain unchanged (except rounding them
- * outside the interpreter!), cf. `compute_glyph_metrics' and
- * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
- * might mess up spacing.
- *
- * Minor hacks
- *
- * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
- * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
- * various sizes.
- *
- * (Post-IUP is the state after both IUP[x] and IUP[y] have been
- * executed.)
- *
- * The best results are achieved for fonts that were from the outset
- * designed with ClearType in mind, meaning they leave the x axis mostly
- * alone and don't mess with the `final' outline to produce more
- * pleasing pixel patterns. The harder the designer tried to produce
- * very specific patterns (`superhinting') for pre-ClearType-displays,
- * the worse the results.
- *
- * Microsoft defines a way to turn off backward compatibility and
- * interpret instructions as before (called `native ClearType')[2][3].
- * The font designer then regains full control and is responsible for
- * making the font work correctly with ClearType without any
- * hand-holding by the interpreter or rasterizer[4]. The v40
- * interpreter assumes backward compatibility by default, which can be
- * turned off the same way by executing the following in the control
- * program (cf. `Ins_INSTCTRL').
- *
- * #PUSH 4,3
- * INSTCTRL[]
- *
- * [1] Tricky fonts as FreeType defines them rely on the bytecode
- * interpreter to display correctly. Hacks can interfere with them,
- * so they get treated like native ClearType fonts (v40 with
- * backward compatibility turned off). Cf. `TT_RunIns'.
- *
- * [2] Proposed by Microsoft's Greg Hitchcock in
- * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
- *
- * [3] Beat Stamm describes it in more detail:
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
- *
- * [4] The list of `native ClearType' fonts is small at the time of this
- * writing; I found the following on a Windows 10 Update 1511
- * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
- * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
- * SimSun, NSimSun, and Yu Gothic.

- /* a Postscript-like interpreter) but rather to perform simple pattern */
- /* matching. */
- /* */
- /* Indeed, nearly all data definitions follow a simple pattern like */

- /* ... /Field <data> ... */
- /* */
- /* where <data> can be a number, a boolean, a string, or an array of */
- /* numbers. There are a few exceptions, namely the encoding, font name, */
- /* charstrings, and subrs; they are handled with a special pattern */
- /* matching routine. */
- /* */
- /* All other common cases are handled very simply. The matching rules */

- /* */
- /* The function `parse_dict' simply scans *linearly* a given dictionary */
- /* (either the top-level or private one) and calls the appropriate */
- /* callback when it encounters an immediate keyword. */
- /* */
- /* This is by far the fastest way one can find to parse and read all */
- /* data. */
- /* */
- /* This led to tremendous code size reduction. Note that later, the */
