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
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.

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.

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.

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/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)

[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without

* 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

- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c,

for LCD-optimized rendering though the new constants/enums:
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
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated
hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated
hinting & rendering

behaviour of the font engine is _unchanged_.

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.

type of `stringOffset' to FT_ULong.

* src/base/ftobjs.c, src/sfnt/ttcmap0.c, src/type1/t1objs.c:
Various fixes to make the FT_CMaps support work correctly (more
tests are still needed).
* include/freetype/internal/ftobjs.h, src/sfnt/Jamfile,
src/sfnt/, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h: Updated
the SFNT charmap support to use FT_CMaps.
* include/freetype/fterrdef.h: New file.
* include/freetype/fterrors.h: Include it. It contains all error
* include/freetype/config/ftheader.h (FT_ERROR_DEFINITIONS_H): New
* include/freetype/internal/ftmemory.h, and a lot of other files:
Changed the names of memory macros. Examples:
FT_NEW was introduced to allocate a new object from a _typed_
Note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced by
FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
This results in _lots_ of sources being changed, but makes the code
more generic and less error-prone.
* include/freetype/internal/ftstream.h, src/base/ftstream.c,
src/cff/cffload.c, src/pcf/pcfread.c, src/sfnt/ttcmap.c,
src/sfnt/ttcmap0.c, src/sfnt/ttload.c, src/sfnt/ttpost.c,
src/sfnt/ttsbit.c, src/truetype/ttgload.c, src/truetype/ttpload.c,
src/winfonts/winfnt.c: Changed the definitions of stream macros.
Also introduced the FT_PEEK_XXXX functions.
* src/cff/cffobjs.c (CFF_Build_Unicode_Charmap): Removed commented
out function.
(find_encoding): Removed.
(CFF_Face_Init): Remove charmap support.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_CMAPS,
TT_CONFIG_CMAP_FORMAT{0,2,4,6,8,10,12}): New macros to fine-tune
support of cmaps.
2002-03-21 David Turner <>
* src/base/ftobjs.c, src/pcf/pcfdriver.c, src/pcf/pcfread.c: Updated
to new FT_CMap definitions.
* src/psaux/t1cmap.h, src/psaux/t1cmap.c, src/type1/t1cmap.h,
src/type1/t1cmap.c: Updating and moving the Type 1 FT_CMap support
from "src/type1" to "src/psaux" since it is going to be shared by
the Type 1 and CID font drivers.
* src/psaux/Jamfile, src/psaux/psaux.c, src/psaux/psauxmod.c,
src/psaux/, include/freetype/internal/psaux.h: Added support
for Type 1 FT_CMaps.
2002-03-20 David Turner <>
* src/base/ftgloadr.c (FT_GlyphLoader_CheckSubGlyphs): Fixed a
memory allocation bug that was due to un-careful renaming of the
FT_SubGlyph type.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fixed a small bug that
caused the library to crash with Electric Fence when memory
debugging is used.
* Renaming stream macros. Examples:
* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed memory leak.
* include/freetype/internal/ftobjs.h: Changing the definition of
FT_CMap_CharNextFunc slightly.
* src/cff/*.c: Updating CFF type definitions.
