Werner Lemberg 319125d4 2017-02-13T09:34:17 [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. * src/autofit/aflatin.c (af_latin_sort_blue): New function. (af_latin_metrics_init_blues): Sort blue values and remove overlaps.
Alexei Podtelezhnikov fcd47b3d 2017-02-12T23:07:29 * src/smooth/ftgrays.c (gray_sweep): Improve code.
Werner Lemberg faa3c882 2017-02-06T13:13:02 [truetype] Implement `VVAR' table support. * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... (GX_HVVarTable): ...This. (GX_Blend): Add fields for `VVAR' table handling. Other minor updates. * src/truetype/ttgxvar.c (ft_var_load_hvar): Renamed to... (ft_var_load_hvvar): ...This. Handle VVAR loading also (controlled by an additional parameter). (tt_hadvance_adjust): Renamed to... (tt_hvadvance_adjust): ...This. Handle application of advance height also (controlled by an additional parameter). (tt_hadvance_adjust, tt_vadvance_adjust): Wrappers for `tt_hvadvance_adjust'. * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated.
Werner Lemberg 144d1087 2017-02-06T07:54:59 Add comment that we don't use VORG table.
Werner Lemberg 1dee4bf9 2017-02-05T08:33:10 [autofit] Use better blue zone characters for lowercase latin. The number of lowercase characters for computing the top flat blue zone value was too small (in most cases only `x' and `z'). If one of the two characters has a large serif, say, it can happen that FreeType must select between two different values, having a 50% chance to use the wrong one. As a result, rendering at larger PPEM values could yield uneven lowercase glyph heights. Problem reported by Christoph Koeberlin <christoph@koe.berlin>. * src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced with... (AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM): ... New, extended sets. (AF_BLUE_STRINGSET_LATN): Updated. * src/autofit/afblue.c, scr/autofit/afblue.h: Regenerated.

Werner Lemberg 8982405f 2017-01-03T09:46:19 [truetype] Various minor fixes. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Check instruction size only if we do native hinting. (TT_Load_Glyph): Trace returned error code. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Trace returned error code. (tt_size_ready_bytecode): Don't run `prep' table if `fpgm' table is invalid.
Werner Lemberg 624b6802 2017-01-03T09:42:41 [sfnt] Don't fail if PCLT, EBLC (and similar tables) are invalid. These tables are optional. * src/sfnt/sfobjs.c (sfnt_load_face): Implement it.
Werner Lemberg 69414e7a 2017-01-03T06:53:13 * src/cff/cffparse.c (cff_parse_num): Simplify.

Werner Lemberg 63765a8f 2017-01-01T10:43:41 [sfnt] Return correct number of named instances for TTCs. Without this patch, requesting information for face index N returned the data for face index N+1 (or index 0). * src/sfnt/sfobjs.c (sfnt_init_face): Correctly adjust `face_index' for negative `face_instance_index' values.

Werner Lemberg c9de4bf6 2016-12-30T10:07:23 Typo.
Werner Lemberg 6b21d128 2016-12-30T10:00:54 [ftfuzzer] Restrict number of tested bitmap strikes. Malformed fonts often have large values for the number of bitmap strikes, and FreeType doesn't check the validity of all bitmap strikes in advance. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353 * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'. (Random): Small class to provide n randomly selected numbers (without repitition) out of the value set [0,N]. (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap strikes.
Werner Lemberg 7591bf11 2016-12-29T21:39:06 [truetype] Variation font API stability issues. Make some functions work before a call to `TT_Set_MM_Blend'. * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if we don't blend. (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we don't blend.
Werner Lemberg 91fc3bd7 2016-12-29T21:34:46 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis data. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=348

Werner Lemberg 6fb549dd 2016-12-28T22:23:33 [psnames] Only declare, not define, data in `pstables.h' (#49949). Pdfium includes `pstables.h' a second time; moving the definition from `pstables.h' to `psmodule.c' saves more than 60kByte data segment space for this case. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist, dump_encoding, dump_array): Emit additional code to only define tables if `DEFINE_PS_TABLES' is set. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c (DEFINE_PS_TABLES): Define.
Werner Lemberg c4a1ef3c 2016-12-28T21:22:45 [cff] Catch `blend' op in non-variant fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=334 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdBLEND>: Don't allow `blend' op for non-variant fonts.
Werner Lemberg c4cd34a9 2016-12-28T08:33:35 [cff] Better check of number of blends. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdBLEND>, src/cff/cffparse.c (cff_parse_blend): Compare number of blends with stack size.
Werner Lemberg 48fd5bb2 2016-12-27T10:20:23 Documentation updates. * docs/CHANGES: Add missing information. * docs/formats.txt: Rewritten and updated.
Werner Lemberg 0a943b63 2016-12-27T07:50:22 Formatting.

Werner Lemberg d1db57c2 2016-12-24T09:05:16 * src/sfnt/ttsbit.c (tt_face_load_sbit): Allow more version values. Some fonts seem to have the `version' field in the wrong byte order. Problem reported by 張俊芝 <418092625@qq.com>.
Werner Lemberg fde0b78c 2016-12-24T08:17:19 * src/truetype/ttpload.c (tt_face_load_loca): Sanitize table length. This trivial fix allows us to accept more fonts. Problem reported by 張俊芝 <418092625@qq.com>.
