f0de218c	2019-05-30T08:43:45	[base] Fix `make multi'. Reported by Nikhil. * src/base/fterrors.c: Include FT_INTERNAL_DEBUG_H.
f37083ed	2019-05-29T08:15:38	[truetype] Fix copy-and-paste error (#56409). * src/truetype/ttgload.c (load_truetype_glyph): Use correct indices into `unrounded' array for phantom points.
49079ce2	2019-05-29T08:08:53	[truetype] Fix 32bit builds (#56404). Patch suggested by Ben Wagner <bungeman@google.com>. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_fixedToFdot6): Remove harmful cast to unsigned type.
86d997e5	2019-05-26T09:37:41	* src/truetype/ttgload.c (TT_Process_Simple_Glyph): Improve accuracy.
306d2f6c	2019-05-23T14:41:57	[truetype] Draw glyphs without deltas in variation font (#56374). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Always fill `unrounded' array.
262fce44	2019-05-21T09:58:51	* src/truetype/ttinterp.c (opcode_name): Improve mnemonics.
141e3173	2019-05-20T23:09:59	Rendering considerations.
b0522701	2019-05-16T12:52:57	[truetype] Actually scale varied CVT values. Up to now, only the unscaled CVT values were varied; in other words, the `CVAR' data was never used for bytecode hinting. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary function. (tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
37580053	2019-05-16T12:15:54	[truetype] Use 26.6 format for storing unscaled CVT values. If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro. (tt_face_vary_cvt): Use it to update code to 26.6 format. * src/truetype/ttobjs.c (tt_size_run_prep): Update code to 26.6 format. * src/truetype/ttpload.c (tt_face_load_cvt): Stora data in 26.6 format.
ac335cd5	2019-05-16T10:15:53	* src/truetype/ttgload.c (load_truetype_glyph): Init `unrounded'. This fixes linear advance width values for spacing glyphs. Bug introduced 2019-05-09.
535b687e	2019-05-16T09:55:16	[truetype] Avoid code duplication. * src/truetype/ttobjs.c (tt_size_run_prep): Scale CVT values in this function. (tt_size_ready_bytecode): Updated. * src/truetype/ttgload.c (tt_loader_init): Updated.
787db7c0	2019-05-13T22:22:57	* vms_make.com: Updated. Handle `bzip2' directory, too.
03f3f8ab	2019-05-13T06:53:19	* src/psaux/psfont.c (cf2_font_setup): Fix compiler warning.
94ebc248	2019-05-12T21:05:36	[truetype] Doh. Fix last commit to make it work. Very embarassing :-) Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14701 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14705 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14710 * src/truetype/ttgload.c (IS_DEFAULT_INSTANCE): Move up and add argument; update all callers. (TT_Process_Simple_Glyph): Use it. The `unrounded' array is active for variation fonts only, thus also enclose related code with `#ifdef TT_CONFIG_OPTION_GX_VAR_SUPPORT ... #endif' where necessary. Revert commit a113e5d from 2019-05-09, and don't use `extra_points2' but allocate a temporary array. Speed up the scaling of the `unrounded' array. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_FixedToFdot6): Fix type conversions and rounding. The unsigned type must have more or equal bits to the signed type.
1178227b	2019-05-11T09:29:19	[truetype] Increase precision of font variation (#54371). This patch make FreeType use font units in 26.6 format internally instead of integers. * src/truetype/ttgxvar.c (FT_fixedToFdot6): New macro. (TT_Vary_Apply_Glyph_Deltas): Add argument to output unrounded font coordinates. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Use `extra_points2' array to temporarily hold unrounded point coordinates; use them to compute scaled coordinates and linear advance width and height. (load_truetype_code): Adjust similarly.
a113e5df	2019-05-09T11:37:58	* src/truetype/ttgload.c (TT_Process_Simple_Glyph): Minor.
bc3b5281	2019-05-08T22:08:40	[smooth] Faster fractions. * src/smooth/ftgrays.c (SUBPIXELS): Replace with... (FRACT): A fractional coordinate macro to use in... (gray_render_line, gray_render_scanline): ... here.
0c6f61ab	2019-05-07T19:07:11	* src/raster/ftraster.c (Draw_Sweep): Unbreak.
ea7e20fb	2019-05-07T07:00:38	* src/raster/ftraster.c: Clean-ups.
dc39f76c	2019-05-07T10:09:55	* src/truetype/ttgxvar.c: More use of `FT_fdot14ToFixed'.
81725773	2019-05-04T08:11:20	* src/smooth/ftgrays.c (gray_render_line): Small shortcut.
7b841047	2019-05-04T08:13:22	Various clang 8.0 static analyzer fixes. Reported by Sender Ghost <lightside@gmx.com>. * src/autofit/afcjk.c (af_cjk_hints_compute_edges): Catch a corner case where `edge->first' could be NULL. * src/pfr/pfrobjs.c (pfr_slot_load): Remove unnecessary test of `size'. * src/raster/ftraster.c (Draw_Sweep): Catch a corner case where `draw_right' might be NULL. * src/sfnt/ttmtx.c (tt_face_get_metrics): Fix limit test for `aadvance'. Ensure `abearing' always hold a meaningful result. * src/truetype/ttgload.c (load_truetype_glyph): Ensure `subglyph' is not NULL before accessing it. * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Remove unnecessary test of `namedstyle'. * src/type42/t42parse.c (t42_parser_done): Ensure `parser->root.funcs.done' is not NULL before accessing it.
300458eb	2019-05-03T23:16:42	Miscellaneous macro updates. * src/base/ftoutln.c (SCALED): Updated. * src/smooth/ftgrays.c (SCALED): Ditto. (FLOOR, ROUND, CEILING): Removed. * src/psaux/psfixed.h (cf2_fracToFixed): Updated.
65f9516b	2019-05-02T23:06:55	Tweak LCD filtering. * src/base/ftlcdfil.c (ft_lcd_filter_fir, _ft_lcd_filter_legacy): Choose direction from bitmap's pixel_mode. * include/freetype/internal/ftobjs.c (FT_Bitmap_LcdFilterFunc): Updated. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Updated.
65e4925a	2019-05-02T07:21:34	* vms_make.com: Updated (#56253). Remove no longer existing directories (`autohint', `otlayout'). Update used base extensions. Activate `autofit' module. Add `gxvalid' module. Update copyright notices.
2ea511ee	2019-04-29T22:49:15	[smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition.
80475ede	2019-04-26T21:53:00	[smooth] Bithacks and cosmetics. * src/smooth/ftgrays.c (gray_record_cell, gray_set_cell, gray_hline, gray_render_conic, gray_convert_glyph_inner): Updated.
7a81b63a	2019-04-25T22:06:33	Optimize Bézier bisections. * src/raster/ftraster.c (Split_Conic, Split_Cubic): Use shifts and refactor. * src/smooth/ftgrays.c (gray_split_conic, gray_split_cubic): Ditto. * src/base/ftstroke.c (ft_conic_split, ft_cubic_split): Ditto. * src/base/ftbbox.c (cubic_peak): Use shifts.
6abce2c2	2019-04-23T06:52:07	* src/sfnt/ttcmap.c (tt_cmap12_next): Remove dead code. Found by clang 8.0's static analyzer and reported by Sender Ghost <lightside@gmx.com>.
4166c453	2019-04-23T06:49:56	[base] Fix thinko in previous commit. * src/base/ftbitmap.c (FT_Bitmap_Blend): Check final width, not target pitch. Problem reported by Sender Ghost <lightside@gmx.com>.
9f6ed105	2019-04-22T08:10:56	* src/base/ftbitmap.c (FT_Bitmap_Blend): Check target pitch. Problem reported by Sender Ghost <lightside@gmx.com>.
af400438	2019-04-22T07:41:35	Fix return value of `FT_Set_Named_Instance' (#56186). * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Correctly handle internal return value -1 of `TT_Set_Var_Design'.
c149f739	2019-04-17T07:49:17	[pcf] Fix handling of undefined glyph (#56067). This commit fixes the changes from 2018-07-21, which broke charmap iteration. We now add the default character as a new glyph with index 0, thus increasing the number of glyphs by one (as before). * src/pcf/pcfread.c (pcf_get_metrics): Adjust to new artificial glyph with index 0. Limit number of elements to 65534. (pcf_get_bitmaps): Ditto. Unify two loops into one; this avoids allocation of an intermediate array. (pcf_get_encodings): Don't flip indices but copy glyph metrics of default character to index 0. Also handle invalid default character. * docs/CHANGES: Updated.
ebe37508	2019-04-15T10:46:19	* CMakeLists.txt: Avoid rewriting of unchanged configuration files. Reported as https://savannah.nongnu.org/patch/index.php?9755
8837ac26	2019-04-15T10:10:38	* src/tools/apinames.c (main): Fix error message. Reported as https://savannah.nongnu.org/patch/?9796
9e9bc9da	2019-04-12T06:19:25	Split off ChangeLog.29.
1f271751	2019-04-11T23:48:21	[smooth] Fix segfault in direct mode (#56092). * src/base/ftoutln.c (FT_Outline_Render): Set missing clip_box for direct mode. * src/smooth/ftgrays.c (gray_raster_render): Use it.
885b4c24	2019-04-06T07:07:37	* src/sfnt/ttcmap.c (tt_get_glyph_name): Pacify compiler (#56061). This is for Visual Studio 2019 on ARM.
74e9ca6d	2019-04-06T06:51:08	For distribution, replace `.tar.bz2' with `.tar.xz' bundles. * builds/toplevel.mk (build): Do it. * README, docs/CHANGES, docs/release: Updated.
3ad1c93a	2019-04-06T06:37:42	Make `glyph_name' parameter to `FT_Get_Name_Index' a `const'. * include/freetype/freetype.h (FT_Get_Name_Index), include/freetype/internal/ftobjs.h (FT_Face_GetGlyphNameIndexFunc), include/freetype/internal/services/svgldict.h (FT_GlyphDict_NameIndexFunc), src/base/ftobjs.c (FT_Get_Name_Index), src/cff/cffdrivr.c (cff_get_name_index), src/sfnt/sfdriver.c (sfnt_get_name_index), src/type1/t1driver.c (t1_get_name_index), src/type42/t42drivr.c (t42_get_name_index): Add `const' to second argument.
6986ddac	2019-03-31T11:08:49	[cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine. Bounds checks have never been updated, however, leading to pointless comparisons of pointers in some cases. This commit presents a solution for bounds checks in the CFF module with an extended logic for the "old" engine while staying as concise as possible for the "new" one. * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and the additional field `t2_strings' within `CFF_ParserRec'. * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary checks into this new function and update the rest of `cffparse.c' to use it. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12137
df266d3e	2019-03-20T07:04:06	[autofit] Fix Mongolian blue zone characters. * src/autofit/afblue.dat: Use U+200D (ZERO-WIDTH JOINER) characters to get medial forms for some Mongolian characters. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
dde03eec	2019-03-19T10:50:38	[autofit] Add support for Mongolian script. As a de-facto standard, layouts using this script are constructed horizontally line by line, then the lines are rotated clockwise for vertical display. * src/autofit/afblue.dat: Add blue zone data for Mongolian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Mongolian standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Mongolian data.
fbbcf503	2019-03-15T07:27:02	* Version 2.10.0 released. ========================== Tag sources with `VER-2-10-0'. * docs/VERSION.TXT: Add entry for version 2.10.0. * docs/CHANGES: Updated. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.9.1/2.10.0/, s/291/2100/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 10. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 23:0:17. * CMakeLists.txt (VERSION_MINOR): Set to 10. (VERSION_PATCH): Set to 0. * builds/toplevel.mk (version, winversion): Since the minor version number has two digits now, never omit the patch number. We would get ambiguous zip file names otherwise. (dist): Remove remnants of `docmaker' tool. (do-dist): Remove unused intermediate files. * src/cff/cffparse.c (destrict_c2s_item): Guard function with CFF_CONFIG_OPTION_OLD_ENGINE macro.
2f4b740c	2019-03-07T09:42:25	Fix invalid function pointer casts. This change should allow Freetype to work on WASM/Emscripten without needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'. * src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature. * src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array, parse_expansion_factor, parse_font_name): Return `void', not `FT_Error'. * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIsDefaultFunc): Fix signature.
31757f96	2019-03-05T11:35:03	[base] Handle numeric overflow (#55827). * src/base/ftglyph.c (FT_Glyph_Get_CBox): Use `FT_PIX_CEIL_LONG'.
6a4718a3	2019-03-05T17:25:19	Fix use of uninitialized memory. * src/psaux/psintrp.c (cf2_interpT2CharString): The call to `cf2_arrstack_setCount' may fail because the allocator ran out of memory. When this happens the stack is still written to before the error condition is checked. This means that FreeType writes outside of allocated memory. This commit moves the error check prior to the stack assignment, hence the function now properly returns with an error condition.
bf04c592	2019-02-25T06:32:26	Minor doc fixes.
6ab36880	2019-02-23T11:18:39	* src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets. The function only provided a framework without an actual implementation, which this commits removes.
75859970	2019-02-23T10:07:09	Update all copyright notices.
fd8fc64e	2019-02-23T10:05:37	* src/tools/update-copyright-year: Insert `(C)'.
8ea854bf	2019-02-21T10:14:57	[truetype] Mask numeric overflows. * src/truetype/ttinterp.c (Move_CVT, Move_CVT_Stretched, Ins_MIRP): Mask numeric overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11681 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11734
5e3a38b1	2019-02-21T10:04:28	[psaux] Mask numeric overflow. * src/psaux/cffdecode.c (cff_decoder_parse_charstrings): Mask numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13041
0ac69211	2019-02-16T07:05:39	* src/autofit/afwarp.h (af_warper_compute): Fix declaration.
29b302ad	2019-02-16T07:05:24	Minor.
a6feefdf	2019-02-02T15:50:57	[truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics. Instead of setting typo or win metrics as the new FT_Face metrics indiscriminately, apply only typo deltas to the currently active FT_Face metrics. This prevents line height differences when e.g. the default outlines were used as the regular face and instances for everything else. * src/truetype/ttgxvar.c (tt_apply_mvar): Implement.
f72b0074	2019-02-02T15:45:31	[sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set. If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set, use the sTypo* set of values to compute the FT_Face's ascender, descender and height. Otherwise, fall back to old behavior. * src/sfnt/sfobjs.c (sfnt_load_face): Implement.
f686ad46	2019-01-22T20:31:44	Update copyright years.
f61f49fe	2019-01-18T13:25:23	[sfnt] Handle TT fonts having two PostScript font names (#55471). * src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any other language found for PostScript font names.
b75abeb5	2019-01-08T20:51:39	[psaux] Fix closepath (#55414). All of the Type 1 path building is done with code common to the revised CFF engine, with the exception of closepath, which was still calling ps_builder_close_contour(), thus previously cached segments were not always written to the path, and glyph corruption, or even invalid outlines were possible. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'.
b89166cc	2018-12-29T08:55:01	* src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310).
afa043de	2018-12-25T22:44:05	Fix links (mostly http -> https).
5e029659	2018-12-25T19:24:06	* src/psaux/cffdecode.c (cff_operaor_seac): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11915
ec439711	2018-12-12T19:59:42	[gxvalid] Fix compiler warnings. * src/gxvalid/gxvjust.c (gxv_just_check_max_gid), src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'.
3e8a2283	2018-12-11T23:54:17	* src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. `control_len' only gets its value from `n_ins' (and vice versa), which is always read as `unsigned short' and thus can't be larger than 0xFFFF.
f1b6183f	2018-12-04T11:51:15	[bdf] Ignore data after `ENDFONT'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10798 * src/bdf/bdflib.c (_bdf_parse_end): New function. (_bdf_parse_glyphs): Switch to `_bdf_parse_end' after `ENDFONT' has been encountered.
456e9c8f	2018-12-02T23:40:55	* builds/windows/visualc/freetype.dsp: Dust off.
3dd4e76b	2018-11-27T23:22:52	* builds/windows/vc2010/freetype.vcxproj: Simplify.
78a1e695	2018-11-27T22:24:06	[type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. For multiple master fonts, common usage (in Postscript) is to modify the WeightVector of an existing font instance, this addition supports that use. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, FT_Get_MM_WeightVector): New API functions. * include/freetype/internalservices/svmm.h (FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New function types. (MultiMasters): Add `set_mm_weightvector' and `get_mm_weightvector' members. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cffcffdrivr.c (cff_set_mm_weightvector, cff_get_mm_weightvector): New functions. (cff_service_multi_masters): Register them. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. This driver doesn't use the new interface. * src/type1/t1load.c (T1_Set_MM_WeightVector, T1_Get_MM_WeightVector): New functions. * src/type1/t1driver.c (t1_service_multi_masters): Register them. * src/type1/t1load.h: Updated.
1fc6937f	2018-11-27T18:02:44	[cff] Fix compiler warning (#55105). * src/cff/cffparse.c (cff_parser_run): Guard label only used if CFF_CONFIG_OPTION_OLD_ENGINE is active.
74cdd75f	2018-11-27T17:55:40	[truetype] Fix numeric overflow (#55103). * src/truetype/ttgload.c (compute_glyph_metrics): Use `SUB_LONG'.
1c4004bb	2018-11-25T23:19:39	[builds] Belated DLL support with vc2002-vc2008. The solution and project files should be automatically upgraded for the approriate Visual C++ version. * builds/windows/visualc/freetype.{sln,vcproj}: Major upgrades. * builds/windows/visualc/index.html: Document the change. * builds/windows/vc2005, builds/windows/vc2008: Removed as redundant.
55b35cd6	2018-11-22T11:43:48	* src/cff/cffparse.c: Please the compiler.
642bc759	2018-11-22T10:29:35	[cff] Fix memory overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9869 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10869 * src/cff/cffparse.c (destruct_t2s_item, cff_parser_run): Store evaluated T2 charstrings in separately allocated memory.
81f43a9d	2018-11-18T14:47:32	* builds/windows/{visualc,vc2005,vc2008}/freetype.vcproj: Fix it.
78db9eec	2018-11-10T15:39:19	[smooth] Placeholder only for library-enabled LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_init): Add disabled `FT_Library_SetLcdFilter' call.
58e48e92	2018-11-09T12:14:35	[psaux] Add safety guard (#54985). * src/psaux/psobjs.c (cff_builder_close_contour): Do it.

[smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition.

Limit number of elements to 65534. (pcf_get_bitmaps): Ditto. Unify two loops into one; this avoids allocation of an intermediate array.

[cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine.

[psaux] Fix closepath (#55414). All of the Type 1 path building is done with code common to the revised CFF engine, with the exception of closepath, which was still calling ps_builder_close_contour(), thus previously cached segments were not always written to the path, and glyph corruption, or even invalid outlines were possible. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'.
