| |
| 2014-12-11 Werner Lemberg <wl@gnu.org> |
| |
| * builds/toplevel.mk (dist): Use older POSIX standard for `tar'. |
| |
| Apparently, BSD tar isn't capable yet of handling POSIX-1.2001 |
| (contrary to GNU tar), so force the POSIX-1.1988 format. |

| [gxvalid] Fix a naming convention conflicting with ftvalid. |
| |
| See previous changeset for otvalid. |
| |
| * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace |
| `valid' by `gxvalid'. |
| * src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c, |
| gxvkern.c, gxvlcar.c, gxvmort.c, gxvmort0.c, gxvmort1.c, |

| 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, |
| otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid' |
| if it is typed as OTV_Validator. |
| |
| 2014-12-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros. |
| |
| Original patch is designed by Werner Lemberg. Extra part |
| for otvalid and gxvalid are added by suzuki toshiya, see |
| discussion: |

| |
| 2014-12-08 Werner Lemberg <wl@gnu.org> |
| |
| [pcf] Fix Savannah bug #43774. |
| |
| Work around `features' of X11's `pcfWriteFont' and `pcfReadFont' |
| functions. Since the PCF format doesn't have an official |
| specification, we have to exactly follow these functions' behaviour. |
| |
| The problem was unveiled with a patch from 2014-11-06, fixing issue |
| #43547. |
| |
| * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last |
| element. Instead, assign real size. |
| |
| 2014-12-07 Werner Lemberg <wl@gnu.org> |
| |
| Work around a bug in Borland's C++ compiler. |
| |
| See |

| |
| [cff] Modify an FT_ASSERT. |
| |
| * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah |
| bug #43661, the test font `...aspartam.otf' still triggers an |
| FT_ASSERT. Since hintmap still works with count==0, ... |
| (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to |
| suppress the assert. |
| |
| 2014-12-04 Dave Arnold <darnold@adobe.com> |

| |
| [autofit] Better fix for conversion specifiers in debug messages. |
| |
| Using `%ld' for pointer differences causes warnings on 32bit |
| platforms. The correct type would be (the relatively new) `%td', |
| however, this is missing on some important platforms. |
| |
| 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. |
| (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, |
| af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'. |
| |
| 2014-12-03 Werner Lemberg <wl@gnu.org> |
| |
| FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality. |
| |
| All public FreeType enumeration and flag values are uppercase... |
| |
| * include/tttables.h (FT_Sfnt_Tag): Implement it. For backward |
| compatibility, retain the old values as macros. |
| |
| * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c |
| (get_sfnt_table): Updated. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| * include/*: Improve structure of documentation. |
| |
| . Add and update many `<Order>' tags. |
| . Apply various documentation fixes. |
| . Remove details to deprecated (or never implemented) data. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Always handle `<Order>' section elements. |
| |
| Previously, those elements were handled only for sections present in |
| a `<Sections>' chapter element. |
| |
| * src/tools/docmaker/content.py (ContentProcessor::finish): |
| Implement it. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Properly handle empty rows in Synopsis. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit |
| ` ' for empty fields. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Thinko. |
| |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): |
| Emit `/empty/' string for first element also. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Honour empty lines in `<Order>' section element. |
| |
| This greatly improves the readability of the `Synopsis' links. |
| |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): |
| Insert string `/empty/' between items. |
| |
| * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it |
| robust against nonexistent keys. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit |
| empty <td> elements for `/empty/'. |
| |
| 2014-12-02 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Ensure Python 3 compatibility. |
| |
| * src/tools/docmaker/content.py (ContentProcessor::set_section, |
| ContentProcessor::finish): Replace `has_key' function with `in' |
| keyword. |
| |
| * src/tools/docmaker/formatter.py (Formatter::__init__): Replace |
| sorting function with a key generator. |
| (Formatter::add_identifier): Replace `has_key' function with `in' |
| keyword. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote): |
| Replace `has_key' function with `in' keyword. |
| (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use |
| integer division. |
| s/<>/>/. |
| |
| * src/tools/docmaker/utils.py: Import `itertools'. |
| (index_sort): Replaced by... |
| (index_key): ... this new key generator (doing exactly the same). |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Don't output a block multiple times. |
| |
| This bug was hidden by not processing all lines of `<Order>' blocks. |
| |
| * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter |
| out field names. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Use field values as HTML link targets where possible. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url): |
| Accept second, optional argument to specify a name. |
| (HtmlFormatter::html_source_quote): Link to field ID if possible. |
| (HtmlFormatter::print_html_field_list): Emit `id' attribute. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Allow empty lines in `<Order>' blocks. |
| |
| Before this patch, the suggested order of entries stopped at the |
| first empty line. |
| |
| Obviously, nobody noticed that this problem caused a much reduced |
| set of links in the `Synopsis' sections; in particular, the |
| `<Order>' blocks contain a lot of entries that wouldn't be listed |
| otherwise... |
| |
| * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): |
| New function to iterate over all items. |
| (DocSection::process): Use it. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp. |
| |
| After the single asterisk there must be no other immediately following |
| asterisk. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |

| together with proper CSS. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Provide higher-level markup and simplify HTML. |
| |
| * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>' |
| elements, use CSS descendants (of class `section') to format the |
| data. |
| |
| Also remove redundant <p> and <br> elements, replacing them with |
| proper CSS. |
| |
| Globally reduce page width to 75%. |
| |
| (block_header): Rename <div> class to `section'. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Add `top' links after blocks. |
| |
| * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Improve CSS for fields. |
| |
| Make fields align horizontally relative to full line width. |
| |
| 2014-11-29 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Fix index and TOC templates. |
| |
| This thinko was introduced 2014-11-27. |
| |
| 2014-11-28 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Format field lists with CSS. |
| |
| This also simplifies the inserted HTML code. |
| |
| * src/tools/docmaker/tohtml.py |
| (HtmlFormatter::print_html_field_list): Do it. |
| |
| 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Fix compiler warning to the comparison between signed and |
| unsigned variable. |
| |
| * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison |
| between `ypos + ysize' and FT_INT_{MAX,MIN}. |
| |
| 2014-11-28 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Replace empty `<td>' with CSS. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do |
| it. |
| |
| 2014-11-28 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'. |
| |
| * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'. |
| (source_*): Use `<div>'. |
| (HtmlFormatter::block_enter): s/<h4>/<h3>/. |
| |
| 2014-11-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |

| |
| * src/tools/docmaker/tohtml.py: Use more CSS for index. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| [docmaker] Replace `name' attribute of `<a>' with `id'. |
| |
| * src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. |
| |
| For `Index' and `TOC' links, we now simply use the `text-align' CSS |
| property of `<td>' to enforce flush-left and flush-right, |
| 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. |
| |
| 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(), |
| cf2font.c could not find it under `make multi' build. |

| |
| * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove |
| unrequired negative value check for `width' and `height'. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: More HTML table refactoring. |
| |
| Replace some `<table>' tags with `<div>' to simplify structure. |
| |
| Move `bgcolor' attribute to CSS. |
| |
| Replace most `width' attributes with CSS. The remaining instances |
| (providing a similar effect as LaTeX's `\hfill' command) are removed |
| in a later patch. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Replace <font> with CSS. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Center <table> with CSS. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |

| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| * src/tools/docmaker/tohtml.py: Remove redundant `<center>' tags. |
| |
| This starts a series of commits into the direction of generating |
| valid HTML 5 code, especially using much more CSS. |
| |
| 2014-11-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |

| suggested by Alexei. |
| |

| too negative values in `x_left' and `y_top'. Either negative |
| values in `width' and `height' are checked. |
| |

| |
| [docmaker] Produce better HTML code. |
| |
| * src/tools/docmaker/tohtml.py: Always use double quotes for |
| attribute values. |
| (source_footer): Close `td' and `tr' groups. |
| |
| 2014-11-27 Werner Lemberg <wl@gnu.org> |
| |
| Use better way to disable creation of .pyc files for `make refdoc'. |
| |
| Python 2.6 was released in 2008... |
| |
| * builds/freetype.mk (refdoc): Use python's `-B' option. |
| |
| * builds/detect.mk (std_setup, dos_setup): Mention required python |
| version for `refdoc' target. |
| |

| |
| Introduced in previous change. Reported by Alexei. |
| |
| 2014-11-26 Werner Lemberg <wl@gnu.org> |
| |
| * src/*: Add checks for parameters of API functions where missing. |
| |
| `API functions' are functions tagged with `FT_EXPORT_DEF'. |
| |
| Besides trivial fixes, the following changes are included, too. |
| |
| * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set |
| error code if no service is available. |
| |
| * src/base/ftinit.c (FT_Done_FreeType): Change return value for |
| invalid `library' parameter to `Invalid_Library_Handle'. |
| |

| [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. |

| `FT_Int32' arguments. This is causing compiler warnings on x86-64: |

| |
| * 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. |

| `vertAdvance' to zero... |
| |
| * src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default |
| value for `vertAdvance' based on `linearVertAdvance' in case |
| `vertAdvance' is zero. Note that the previous computed ad-hoc value |
| for `linearVertAdvance' was apparently not tested in a real-life |
| situation. |
| |

| |
| [base] Significant optimization of `ft_div64by32' |
| |
| We shift as many bits as we can into the high register, perform |
| 32-bit division with modulo there, then work through the remaining |
| bits with long division. This optimization is especially noticeable |
| for smaller dividends that barely use the high register. |

| 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> |
| |
| Make `FT_Get_SubGlyph_Info' actually work. |
| |
| * src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok |
| if there is no error. |
| |
| 2014-04-15 Werner Lemberg <wl@gnu.org> |
| |
| [afblue.pl]: Minor improvements. |
| |
| * src/tools/afblue.pl: Allow whitespace before comments. |
| Ignore whitespace in strings. |
| |
| 2014-04-14 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Improve coverage handling. |
| |
| * src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs |
| appearing in the GPOS table if we are processing the default |
| coverage. |
| |
| 2014-04-13 David Weber <weber.aulendorf@googlemail.com> |
| |
| [smooth] Fix stand-alone compilation. |
| |
| * src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define. |
| |
| 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. |
| |
| * src/autofit/aflatin.h: Updated. |
| * src/autofit/afcjk.c: Updated. |
| |
| 2014-04-03 Werner Lemberg <wl@gnu.org> |
| |
| Don't require `gzip' module for `sfnt'. |
| |
| Reported by Preet <prismatic.project@gmail.com>. |
| |
| * src/sfnt/sfobjs.c (woff_open_font): Guard use of |
| FT_Gzip_Uncompress with FT_CONFIG_OPTION_USE_ZLIB. |
| |
| 2014-03-27 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #38235. |
| |
| Work around a bug in pkg-config version 0.28 and earlier: If a |
| variable value gets surrounded by doublequotes (in particular values |
| for the `prefix' variable), the prefix override mechanism fails. |
| |
| * builds/unix/freetype2.in: Don't use doublequotes. |
| * builds/unix/unix-def.in (freetype.pc): Escape spaces in directory |
| names with backslashes. |
| |
| 2014-03-24 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #41946. |
| |

| |
| Rewrite library option handling in `configure'. |
| |
| o Introduce `auto' value for `--with-XXX' library options; this is |
| now the default. |
| |
| o First use `pkg-config' for library detection, then fall back to |
| other tests. |
| |
| * builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png, |
| --with-harfbuzz): Rewrite. |
| Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf' |
| variables to collect data for `freetype2.pc' and `freetype-config'. |

| (ft2_extra_libs): This since it gets no longer substituted. |
| (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG): |
| New output variables, replacing `XXX_PKG' and `LIBXXX'. |
| Add notice at the end of `configure' showing the library |
| configuration. |

| |
| Avoid `long long' warnings with older gcc compilers. |
| Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. |
| |
| * builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for |
| versions < 4.6. This is especially needed for Max OS X since this |
| OS runs a gcc variant (or emulation) based on version 4.2.1. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |
| * docs/INSTALL.CROSS: Revised and updated. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |
| |

| |
| This is a generated file at build time, not configure time. |
| |
| * builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ... |
| (CLEAN): This variable. |
| |
| 2014-03-01 Werner Lemberg <wl@gnu.org> |

| |
| * src/cff/cf2ft.c (cf2_initLocalRegionBuffer, |

| |
| [cff] Fix Savannah bug #41697, part 1. |
| |
| * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is |

| `hStemHintArray'; the exception has already been recorded in |
| `hintMask'. |

| |
| 2014-02-26 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |

| |
| Fix compilation with MinGW. |
| |
| Right now, compilation out of the box with latest MinGW is broken |
| due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode, |
| cf. |
| |
| https://sourceforge.net/p/mingw/bugs/2024/ |
| https://sourceforge.net/p/mingw/bugs/2046/ |
| |
| * builds/unix/configure.raw: Don't set `-ansi' flag for MinGW. |
| |
| 2014-02-04 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Minor fix. |
| |
| * src/autofit/afcjk.c (af_cjk_metrics_init_widths), |
| src/autofit/aflatin.c (af_latin_metrics_init_widths): Fix handling |
| of alternative standard characters. |

| |
| 2014-01-26 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Introduce two more slots for standard characters. |
| |
| This is useful for OpenType features like `c2sc' (caps to small |
| caps) that don't have lowercase letters by definition, or other |
| features that mainly operate on numerals. |
| |
| * src/autofit/afscript.h: Add more standard characters. |
| |
| * src/autofit/aftypes.h: Update use of `SCRIPT' macro. |

| |
| * src/autofit/afcjk.c (af_cjk_metrics_init_widths), |
| src/autofit/aflatin.c (af_latin_metrics_init_widths): Scan two more |
| standard characters. |

| |
| [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. |
| Use it, together with AF_CONFIG_OPTION_INDIC and |
| AF_CONFIG_OPTION_CJK, to update. |
| |
| * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated. |
| [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed. |
| Sort entries by tags. |
| |

| |
| [autofit] Thinko. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Similar to |
| `af_get_coverage', reject glyphs which are not substituted. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix handling of default coverages. |
| |
| With this commit, the implementation of coverage handling is |
| completed. |
| |
| * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to |
| do. |
| Reject coverages which don't contain appropriate glyphs for blue |
| zones. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix handling of default coverages. |
| |
| * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): |
| First handle non-default coverages, then the default coverage of the |
| default script, and finally the other default coverages. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix scaling of HarfBuzz shaping. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM. |
| |
| 2014-01-03 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Better ftgrid support. |
| |
| * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add |
| parameters `is_blue' and `blue_offset'. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Remove some styles. |
| |
| * src/autofit/afcover.h: Remove coverages for alternative fractions, |
| denominators, numerators, and fractions. |
| |
| * src/autofit/afstyles.h (META_STYLE_LATIN): Updated. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Add more styles. |
| |
| * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New |
| auxiliary macros; use them to define styles for Cyrillic, Greek, and |
| Latin. |
| |
| * src/autofit/afcover.h: Remove coverage for oldstyle figures. |
| Since those digits are used in combination with ordinary letters, it |
| makes no sense to handle them separately. |
| |
| * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit |
| `options' parameter to 4 bits. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix style assignments to glyphs. |
| |
| * src/autofit/hbshim.c (af_get_coverage) |
| [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also |
| so that we can skip glyphs that have both GSUB and GPOS data. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/. |
| |
| 2014-01-01 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Implement and use `af_get_char_index' with HarfBuzz. |
| |
| * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]: |
| Redefine to construct HarfBuzz features. |
| (af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten. |
| |
| * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use |
| `y_offset' to adjust `best_y'. |
| |
| 2013-12-31 Werner Lemberg <wl@gnu.org> |

| |
| 2013-12-31 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Fix interface of `af_get_char_index'. |
| |
| * src/autofit/hbshim.c (af_get_char_index): Return error value. |
| Add argument for y offset (to be used in a yet-to-come patch). |
| |
| * src/autofit/hbshim.h, src/autofit/afcjk.c, |
| src/autofit/aflatin.c: Updated. |
| |
| 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 |
| complicated code, as investigations have shown meanwhile. The major |
| drawback is that we run out of available style slots much earlier. |
| However, this is only a theoretical issue since we don't support a |
| large number of scripts currently. |
| |
| * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with |
| a single-element `COVERAGE' macro, sort the elements by the feature |
| tags, and add entry for `ruby'. |
| |
| * src/autofit/aftypes.h: Updated. |
| * src/autofit/hbshim.c: Updated. |
| |
| 2013-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Code shuffling to reduce use of cpp macros. |
| |
| * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): |
| Call `af_get_coverage' unconditionally. |
| |
| * src/autofit/autofit.c: Include `hbshim.c' unconditionally. |
| |
| * src/autofit/hbshim.c (af_get_coverage) |
| [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. |
| |
| * src/autofit/hbshim.h: Provide function declarations |
| unconditionally. |
| |
| 2013-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Add wrapper function for `FT_Get_Char_Index'. |
| |
| Yet-to-come changes will provide HarfBuzz functionality for the new |
| function. |
| |
| * src/autofit/hbshim.c (af_get_char_index): New function. |
| * src/autofit/hbshim.h: Updated. |
| |

| af_latin_metrics_init_blues, af_latin_metrics_check_digits): |
| Updated. |
| |
| 2013-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Use `global' HarfBuzz font object. |
| |
| We now use `hb_font' instead of `hb_face' since yet-to-come changes |
| need this. |
| |
| * src/autofit/afglobal.h: Include `hbshim.h'. |
| (AF_FaceGlobalsRec) [FT_CONFIG_OPTION_USE_HARFBUZZ]: New member |
| `hb_font'. |
| |
| * src/autofit/afglobal.c (af_face_globals_new) |
| [FT_CONFIG_OPTION_USE_HARFBUZZ]: Create `hb_font'. |
| (af_face_globals_free) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Destroy |
| `hb_font'. |
| |
| * src/autofit/hbshim.h: Include HarfBuzz headers. |
| |
| * src/autofit/hbshim.c: Include `hbshim.h' instead of HarfBuzz |
| headers. |
| (af_get_coverage): Updated. |
| |
| 2013-12-27 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Handle `DFLT' OpenType script for coverages. |
| |
| * include/ftautoh.h: Document new `default-script' property. |
| |
| * src/autofit/hbshim.c (af_get_coverage): Use `AF_FaceGlobals' for |
| type of first parameter. |

| member. |

| [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. |

| resource, and disable the sorting for `sfnt' resource. |

| |
| Fix Savannah bug #40997. |
| |
| * src/bdf/bdfdrivr.c (BDF_Face_Init): Only use OR operator to |
| adjust face flags since FT_FACE_FLAG_EXTERNAL_STREAM might already |
| be set. |
| * src/cff/cffobjs.c (cff_face_init): Ditto. |
| * src/cid/cidobjs.c (cid_face_init): Ditto. |

| 2013-12-21 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |

| (AF_DEFINE_STYLE_CLASS): Updated. |
| |
| * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage |
| data. |
| |
| * src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros. |
| (AF_SCRIPT_FALLBACK): Renamed to ... |
| (AF_STYLE_FALLBACK): ... this. |
| |
| * src/autofit/afglobal.c: Include `hbshim.c'. |
| Update use of `SCRIPT' and `STYLE' macros. |
| (af_face_globals_compute_style_coverage) |
| [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. |
| Update. |
| |

| `hbshim.c'. |
| |
| * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'. |
| (AUTOF_DRV_H): Add `afcover.h'. |
| |
| * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Use pkg-config for |
| all libraries needed by FreeType. |
| |
| 2013-12-21 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #40975 (sort of). |
| |
| * src/truetype/ttinterp.c (Ins_IP): Fix sign typo to make FreeType |
| behave the same as the Windows TrueType engine for the invalid case. |
| |
| 2013-12-21 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Make PIC mode work actually. |

| src/autofit/aflatin.c (af_latin_metrics_init_widths) |
| [FT_CONFIG_OPTION_PIC]: Declare `globals'. |
| |
| * src/autofit/afglobal.c: Always call AF_DEFINE_SCRIPT_CLASS, and |
| AF_DEFINE_STYLE_CLASS. |
| |
| * src/autofit/afpic.c: Include `afglobal.h'. |
| (autofit_module_class_pic_init): Typo. |

| |
| Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>. |
| |
| * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to |
| `Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a |
| `IS_HINTED' clause. |
| Also remove redundant check using `maxSizeOfInstructions' – in |
| simple glyphs, the bytecode data comes before the outline data, and |
| a validity test for this is already present. |

| |
| 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/freetype-config.in, builds/unix/freetype2.in: For |
| `--cflags', return a single directory. |
| * builds/unix/install.mk (install): No longer try to remove `cache' |
| and `internal' subdirectories; instead, remove the `freetype' |
| subdirectory. |

| Fix horizontal position of `pp3' and `pp4'. |

| |
| [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. |

| Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): |
| Updated. |

| shouldn't be any ABI problems. |
| |
| * src/sfnt/ttload.c (tt_face_load_os2): Implement it. |

| [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 |
| linear function where the slope was zero. The recovery was to use a |
| different section of the function, which produced a different, |
| incorrect amount of darkening. |

| * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. |
| |
| 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). |
| |
| * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' |
| to indicate that we synthesize a closepath line. |
| |
| * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. |
| (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for |
| `lineto' operator) and adjust hint zone. |
| For synthesized closing lines, use end point in first hint zone. |
| (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. |
| Updated. |
