7ae9b999	2016-05-07T16:24:03	[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'.
6e88087d	2016-05-05T23:41:03	[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.
0b3cb8a8	2016-05-05T12:28:48	[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.
22167629	2016-04-25T21:18:24	[autofit] Add blue-zone support for Gujarati script. This essentially moves the Gujarati script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Gujarati. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Gujarati standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Gujarati data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Gujarati data; in particular, use AF_WRITING_SYSTEM_LATIN.
d9fb2175	2016-04-24T15:27:32	Minor. * include/freetype/freetype.h (FT_HAS_, FT_IS_): Protect macro argument with parentheses.
432e00db	2016-04-24T08:14:07	[truetype] Fix deallocation in case of error (#47726). * src/truetype/ttgload.c (load_truetype_glyph): Initialize fields in `outline' that are going to be deallocated in case of error.
80afef8b	2016-04-23T21:34:15	[autofit] Improve Georgian blue zone characters. Suggested by Akaki Razmadze <razmadzekoko@gmail.com>. * src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM): Updated. * src/autofit/afblue.c: Regenerated.
9224f053	2016-04-16T10:24:24	[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 because zlib target isn't in the export set). * CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings.
99eff678	2016-04-16T07:32:23	[truetype] Another fix for non-intermediate GX tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing cases.
213f0ca3	2016-04-13T00:19:54	Remove forgotten macro. * include/freetype/internal/internal.h [FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove.

c8c7ad79	2016-04-09T08:24:00	[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. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data.

bf8f100d	2016-04-05T11:43:58	[autofit] Provide dummy blue zone for pseudo script `none'. Even if the dummy hinter is used as the handler for `none' (which doesn't use blue zones), it is more consistent than the old value (which was 0), pointing to Arabic... * src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE.
fb550bf4	2016-03-30T18:55:27	* src/pfr/pfrload.c (pfr_aux_name_load): Thinko (#47567).
aff6ebb9	2016-03-30T09:11:02	* src/pfr/pfrload.c (pfr_log_font_count): Better font size estimate.
ccd771cd	2016-03-30T08:44:46	* src/pfr/pfrload.c (pfr_aux_name_load): Fix memory leak (#47567).
ff82747e	2016-03-29T09:19:22	* src/base/ftadvance.c (FT_Get_Advances): Fix invalid left shift.
351fc4b4	2016-03-29T09:13:13	[pfr] Fix binary search (#47514). * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Handle border conditions correctly.
2a03e5d9	2016-03-29T08:56:03	[pfr] Minor. * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Replace `left', `right', and `middle' with `min', `max', and `mid' as used in other FreeType binary search code. (pfr_load_bitmap_metrics): Fix invalid left shift.
31dc8f98	2016-03-29T08:37:07	* src/pfr/pfrtypes.h: Replace all enums with macros. We need `~FOO' to unset bits, and only with unsigned values (which `enum' isn't normally) this works cleanly.
b069a590	2016-03-26T08:00:07	[pfr] Robustify bitmap strike handling (#47514). We did a binary search for a charcode without ensuring that the searched data is ordered. Validating the order is now done lazily, this is, the first access to a bitmap glyph triggers the order check in the corresponding bitmap strike. * src/pfr/pfrtypes.h (PFR_BitmapFlags): New values `PFR_BITMAP_VALID_CHARCODES' and `PFR_BITMAP_CHARCODES_VALIDATED'. * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Make `flags' argument a pointer. Handle new PFR_BITMAP_XXX flags. (pfr_slot_load_bitmap): Updated.
0003cb91	2016-03-26T07:34:30	[pfr] Fix handling of compound glyphs. Extra items are indicated with different bit positions. * src/pfr/pfrtypes.h (PFR_GlyphFlags): Replace `PFR_GLYPH_EXTRA_ITEMS' with `PFR_GLYPH_SIMPLE_EXTRA_ITEMS' and `PFR_GLYPH_COMPOUND_EXTRA_ITEMS'. * src/pfr/pfrgload.c (pfr_glyph_load_simple, pfr_glyph_load_compound): Use them.
2aa69565	2016-03-25T10:54:37	[pfr] Minor. * src/pfr/pfrsbit.c, srf/pfr/pfrobjs.c: Use flag names instead of bare numbers.
59828f72	2016-03-25T08:47:14	[pfr] Various clang sanitizer fixes. * src/pfr/pfrsbit.c (pfr_load_bitmap_metrics): Correctly handle signed nibbles. (pfr_slot_load_bitmap): Correctly exit frame in case of error. Fix invalid left shifts.
6e89ad41	2016-03-23T07:40:12	Rename `VERSION.DLL' (#47472). * docs/VERSION.DLL: Renamed to... * docs/VERSIONS.TXT: ...this.
31f2dc19	2016-03-23T07:31:59	[raster, smooth] Directly test outline size (#47500). This improves stand-alone compilation. * src/base/ftoutln.c (FT_Outline_Render): Move cbox size test to... * src/raster/ftraster.c (ft_black_render), src/smooth/ftgrays.c (gray_raster_render): ...these functions.
e9181aba	2016-03-23T06:58:20	[raster, smooth] Fix some clang sanitizer runtime issues. * src/raster/ftraster.c (ft_black_reset, ft_black_set_mode, ft_black_render): Harmonize signatures with `ftimage.h'. * src/smooth/ftgrays.c (gray_raster_render, gray_raster_reset): Ditto.
b6633073	2016-03-22T08:26:55	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Minor. This fixes an AddressSanitizer issue: ttgload.c:430:7: runtime error: null pointer passed as argument 1, which is declared to never be null
614a8f17	2016-03-21T19:39:14	* src/autofit/afhints.c (af_glyph_hints_reload): Thinko. This fixes the previous commit to this file.
3beccbdf	2016-03-21T00:07:47	[smooth] Partly revert recent changes. * src/smooth/ftgrays.c (gray_conic_to, gray_cubic_to): Rework conditions to fix rendering issues.
709486db	2016-03-20T22:20:32	[autofit] Show `near' points in tracing. * src/autofit/afhints.h (AF_FLAG_NEAR): New macro. * src/autofit/afhints.c (af_glyph_hints_dump_points): Implement it. (af_glyph_hints_reload): Handle AF_FLAG_NEAR.
8e8bb126	2016-03-18T23:21:59	[smooth] Minor refactoring and microoptimizations. * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move band clipping from here. (gray_conic_to, gray_cubic_to): ... to here. (gray_rander_line, gray_render_scanline): Initialize variables closer to their use.

da86b73f	2016-03-15T07:55:05	* src/autofit/aflatin.c (af_latin_compute_stem_width): Optimize.
1865575a	2016-03-14T22:39:22	[smooth] Temporarily revert 6eb6158dd787 (#47114). * src/smooth/ftgrays.c (gray_render_line): Old implementation.
ee6b4115	2016-03-12T23:48:13	[ftfuzzer] Improve coverage of rasterfuzzer. * src/tools/ftfuzzer/rasterfuzzer.cc (LLVMFuzzerTestOneInput): Use input data for `tags' array also. Trim input data to get more positive hits.
10265db1	2016-03-11T06:50:23	Fix CMake issues for iOS (patch #8941). * CMakeLists.txt (CMAKE_TOOLCHAIN_FILE): Fix directory. * builds/cmake/iOS.cmake: No longer enforce gcc.
74c0a72d	2016-03-09T20:35:27	[truetype] Fix handling of non-intermediate GX tuples. We probably did not notice this as all fonts we tested had only tuple_coords[i] be +1 or -1 for non-intermediate tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Implement it.
495de6cc	2016-03-06T23:54:34	[base] Refuse to render enormous outlines (#47114). The goal is to avoid integer overflows in the rendering algorithms. The limit is chosen arbitrarily at some 2^18 pixels, which should be enough for modern devices including printers. * src/base/ftoutln.c (FT_Outline_Render): Check CBox and reject enormous outlines.
d0b0e31e	2016-03-06T23:01:50	[smooth] Replace left shifts with multiplications (#47114). * src/smooth/ftgrays.c (SUBPIXELS, UPSCALE, DOWNSCALE): Do it.
caa48b0d	2016-03-05T19:47:07	[autofit] Avoid excessive stem length rounding (#25392). * src/autofit/aflatin.c (af_latin_compute_stem_width): Add argument to pass difference between hinted and unhinted position of base point; use this to adjust the stem width depending on the PPEM so that it doesn't become too large under certain circumstances. Update all callers using value 0 for this argument except... (af_latin_align_linked_edge): Pass position delta of base point to `af_latin_compute_stem_width'.
1fd2bc8c	2016-03-05T16:38:35	Make FreeType compile on AIX out of the box. * builds/unix/configure.raw (XX_ANSIFLAGS): Don't use `-ansi' on AIX.
a8b95622	2016-03-01T09:37:12	[ftfuzzer] Add unit for testing smooth and black rasterizers. * src/tools/ftfuzzer/rasterfuzzer.cc: New file.

5c7646d2	2016-02-29T09:12:35	[autofit] Add blue-zone support for Sinhala script. This essentially moves the Sinhala script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Sinhala. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Sinhala standard character and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Sinhala data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Sinhala data; in particular, use AF_WRITING_SYSTEM_LATIN.
f2169478	2016-02-28T22:48:34	[autofit] Properly handle spikes pointing to the x-axis. An example that gets better rendered is glyph `uusignTaml' (glyph index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly handle segments where the last point of the first segment is identical to the first point in the second one. This can happen for malformed fonts or spikes. We either merge the new segment with the previous one (both segments point into the same direction), or we discard the shorter segment if they point into different directions.
ce486645	2016-02-27T15:01:49	[autofit] Minor code clean-up. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Change some local variable names to better differentiate between values along a segment and values orthogonal to it.
ebfd7ce5	2016-02-26T08:10:41	[autofit] Improve BOUND action. In complex glyph shapes, the original logic was too simple to cater for situations that would actually need something similar to PS Hint masks. This fix should alleviate the worst cases. * src/autofit/aflatin.c (af_latin_hint_edges): Don't allow complete disappearance of stems.
44324b37	2016-02-25T06:58:47	[autofit] Add blue-zone support for Tamil script. This essentially moves the Tamil script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Tamil. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Tamli standard character and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Tamil data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Tamil data; in particular, use AF_WRITING_SYSTEM_LATIN.
a5952d30	2016-02-18T12:56:38	[autofit] Add blue-zone support for Malayalam script. This essentially moves the Malayalam script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Malayalam. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Malayalam standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Malayalam data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Malayalam data; in particular, use AF_WRITING_SYSTEM_LATIN.
08e89b73	2016-02-16T22:32:13	[smooth] Fix integer overflow (#47114). * src/smooth/ftgrays.c (TArea): Make it unconditionally `long'.
3a5e5078	2016-02-15T22:21:01	* src/cff/cffparse.c (cff_parse_multiple_master): Improve tracing.
2873010d	2016-02-15T20:53:22	[cff] Handle T2 operator only with old CFF engine (#47157). * src/cff/cffparse.c (cff_parser_run) <opcode 31>: Enclose with
8ed9eaf1	2016-02-15T20:41:58	[cff] Partially handle `load' and `store' ops in old CFF engine. Now all glyphs of MM CFFs like `ITCGaramondMM-It.otf' can be displayed. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_store, cff_op_load>: Partially implement it. * src/cff/cffparse.c (cff_parser_init): Add new parameter to pass the number of Multiple Master axes. Update all callers. (cff_parse_multiple_master): Get number of axes. (cff_parser_run) <opcode 31>: Updated. * src/cff/cffparse.h: Updated. (CFF_ParserRec): Add `num_axes' field. * src/cff/cffload.c: Updated. * src/cff/cfftypes.h (CFF_FontRecDictRec): Add `num_axes' field.
658f530e	2016-02-15T14:28:28	[cff] Correctly trace SIDs that contain NULL bytes. We need this to properly trace Multiple Master CFFs, which contain two SIDs that are charstrings. This commit makes FreeType also show the last SID, omitted previously due to a bug. * src/cff/cfftypes.h (CFF_FontRec): Add `string_pool_size' field. * src/cff/cffload.c (cff_index_get_pointers): Add argument to return the pool size. Update all callers. * src/cff/cffobjs.c (cff_face_init) [FT_DEBUG_LEVEL_TRACE]: Directly access `cff->strings' to display the non-default strings.

dc5b2e82	2016-02-14T20:47:28	* src/cff/cffparse.c: Include `cffgload.h'. Problem reported by Colin Walters <walters@verbum.org>.
813aca51	2016-02-14T16:03:15	[cff] Make old CFF engine show MM CFFs (without variations). The new code only displays the first master in the font. * src/cff/cffgload.c (cff_decode_parse_charstrings): Add new parameter to allow function calls from dictionaries also. <cff_op_blend>: Partially implement it. Update all callers. * src/cff/cffgload.h: Updated. * src/cff/cffparse.c (cff_parser_init): Add new parameter to pass the number of Multiple Master designs. Update all callers. (cff_parse_multiple_master): New function to rudimentarily parse operator. (cff_parser_run): Handle `T2' operator. * src/cff/cffparse.h: Updated.

4b3ea5ca	2016-02-09T08:08:17	[docmaker] Don't emit trailing newlines. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_code): Use `rstrip'.
44accb9e	2016-02-08T19:51:40	Version 2.6.3 released.
78371bd6	2016-02-07T21:06:59	Fix another runtime error found by clang's sanitizer (#47082). * src/base/ftstroke.c (ft_stroke_border_export): Properly handle empty input buffer.
0d053bac	2016-02-07T19:25:56	Fix runtime errors found by clang's sanitizer (#47082). * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Copy), src/cache/ftcsbits.c (ftc_sbit_copy_bitmap): Properly handle empty input buffer.

ec776596	2016-01-19T19:33:57	[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.

[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. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data.

[autofit] Properly handle spikes pointing to the x-axis. An example that gets better rendered is glyph `uusignTaml' (glyph index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly handle segments where the last point of the first segment is identical to the first point in the second one. This can happen for malformed fonts or spikes. We either merge the new segment with the previous one (both segments point into the same direction), or we discard the shorter segment if they point into different directions.

[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.
