6b21d128 2016-12-30 10:00:54 [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.
7591bf11 2016-12-29 21:39:06 [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.

3205a44d 2016-12-09 06:55:34 [sfnt] Revert change from 2016-12-08. I missed the functionality of `ft_module_get_service', which makes the change unnecessary.
29aa9577 2016-12-08 08:59:34 [sfnt] Add `get_glyph_name' and `get_name_index' to SFNT interface. CFF2 fonts will need access to those two functions. * include/freetype/internal/sfnt.h: Include FT_SERVICE_GLYPH_DICT_H. (SFNT_Interface): Add `get_glyph_name' and `get_name_index' members. (FT_DEFINE_SFNT_INTERFACE): Updated. * src/sfnt/sfdriver.c (sfnt_get_glyph_name, sfnt_get_name_index): Fix signatures to exactly correspond to the glyph dict service function typedefs. (sfnt_interface): Updated.
ffd8f622 2016-12-06 07:25:16 [cff] Code shuffling. This is a preparation for better integrating Dave Arnold's changes.
bcae6574 2016-12-05 22:08:15 Add `FT_Get_Var_Design_Coordinates' function. Note that the low-level functions aren't implemented yet. * include/freetype/ftmm.h: Declare. * include/freetype/internal/services/svmm.h (FT_Get_Var_Design_Func): New typedef. (MultiMasters): New MM service function `get_var_design'. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. Update all callers. * src/base/ftmm.c (FT_Get_Var_Design_Coordinates): Implement. * src/truetype/ttdriver.c: Updated. * src/truetype/ttgxvar.c (TT_Get_Var_Design): New dummy function to handle `get_var_design' service. * src/truetype/ttgxvar.h: Updated. * src/type1/t1driver.c: Updated. * src/type1/t1load.c (T1_Get_Var_Design): New dummp function to handle `get_var_design' service. * src/type1/t1load.h: Updated.

602be7c8 2016-12-01 11:36:37 [gzip] Improve building with external zlib (#49673). Building FreeType with external zlib 1.2.8 makes msvc 14 stop with the following error. ftgzip.c zlib-1.2.8\zlib.h(86): error C2061: syntax error: identifier 'z_const' zlib-1.2.8\zlib.h(94): error C2054: expected '(' to follow 'z_const' zlib-1.2.8\zlib.h(94): error C2085: 'msg': not in formal parameter list ... zlib-1.2.8\zlib.h(877): fatal error C1003: error count exceeds 100; stopping compilation The error happens because FreeType keeps an own copy of zlib-1.1.4 under `src/gzip'. When building `src/gzip/ftgzip.c' with FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses #include <zlib.h> which correctly finds an external `zlib.h', but `zlib.h' itself has a line #include "zconf.h" which makes Visual Studio 2015 find `src/gzip/zconf.h' while compiling the files in `src/gzip'. * src/gzip/zconf.h: Rename to... * src/gzip/ftzconf.h: ... this. * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.
255828c8 2016-12-01 07:07:22 [autofit] Fix Emscripten crash (patch #9180). Function calls through pointers must use a matching signature to work on Emscripten, since such calls are dispatched through lookup tables grouped by signature. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Fix typedef.
1d28f697 2016-11-29 18:45:22 [smooth] Revert previous commit. Already fixed with 6ca54c64.
d949a3db 2016-11-29 12:09:56 [smooth] Avoid conditional jump on uninitialized value (#49711). * src/smooth/ftgrays.c (gray_raster_render): Initialize `worker'.
b37b799c 2016-11-27 16:30:53 [autofit] Code shuffling. Also improve some comments and remove unused code. No functional change. * src/autofit/afloader.c (af_loader_load_g): Merged with... (af_loader_load_glyph): ...this function. Split off emboldening code into... (af_loader_embolden_glyph_in_slot): ... this function.
48c77da3 2016-11-17 07:37:50 Add minor comment to avoid confusion (#19044).
e1ee5476 2016-11-06 12:39:05 * src/base/ftobjs.c (FT_Render_Glyph_Internal): Fix tracing.
1c6fd994 2016-11-06 12:37:55 [sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format. It's unavoidable to call the PNG engine, but to get the metrics it is sufficient to read the PNG image's header only. * src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the allocation of the glyph slot. * src/sfnt/pngshim.h: Updated. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_png, tt_face_load_sbix_image, tt_face_load_sbit_image): Updated.
565db95b 2016-11-06 12:33:51 [sfnt] Speed up `sbix' lookup. This also fixes a bug introduced in 2016-10-01 which prevents display of embedded bitmap fonts that use the `sbix' format. * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and offset also in `ebdt_size' and `ebdt_start', respectively. This makes the test for an embedded bitmap data table succeed for this format. (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `ebdt_size' and `ebdt_start' (tt_face_load_sbix_image): Ditto.
37e193e9 2016-11-06 12:32:51 Introduce a way of quickly retrieving (embedded) bitmap metrics. `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph until the user calls `FT_Render_Glyph'. However, it always allocates memory for bitmaps and copies or decodes the contents of a bitmap glyph, which can be quite slow for PNG data. * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if FT_LOAD_BITMAP_METRICS_ONLY is used. * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_bitmap): Add argument to control allocation of the glyph slot. (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound, tt_face_load_sbit_image): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if `FT_LOAD_BITMAP_METRICS_ONLY' is set. * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add argument to control allocation of the glyph slot. * src/pfr/pfrobjs (pfr_slot_load): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. * docs/CHANGES: Updated.
b72858c9 2016-11-03 06:41:00 [truetype] Clamp variation requests to valid range. This is required by OpenType 1.8; it also avoids rounding surprises. * src/truetype/ttgxvar.c (TT_Set_Var_Design): Clamp design coordinates outside of the allowed range to always stay within the range instead of producing an error.
328d6844 2016-10-29 00:18:56 [truetype] Remove clang warnings. * src/truetype/ttinterp.h (TT_ExecContextRec): Using `FT_ULong' for loop counter handling. * src/truetype/ttinterp.c: Updated. (Ins_SCANTYPE): Use signed constant. (TT_RunIns): Ensure `num_twilight_points' is 16bit.
ddf38726 2016-10-27 07:27:27 [truetype] Fix commit from 2014-11-24. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/truetype/ttpload.c (tt_face_load_hdmx): Fix file checking logic.
9c45ac39 2016-10-26 16:00:00 Add `FT_Get_{MM,Var}_Blend_Coordinates' functions. * include/freetype/ftmm.h: Declare. * include/freetype/internal/services/svmm.h (FT_Get_MM_Blend_Func): New typedef. (MultiMasters): New MM service function `get_mm_blend'. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. Update all callers. * src/base/ftmm.c (FT_Get_MM_Blend_Coordinates, FT_Get_Var_Blend_Coordinates): Implement. * src/truetype/ttdriver.c: Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Blend): New function to handle `get_mm_blend' service. * src/truetype/ttgxvar.h: Updated. * src/type1/t1driver.c: Updated. * src/type1/t1load.c (T1_Get_MM_Blend): New function to handle `get_mm_blend' service. * src/type1/t1load.h: Updated. * docs/CHANGES: Document.
56140907 2016-10-26 08:10:59 * src/type1/t1load.c (parse_subrs): Fix limit check. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=81
c5f1bc4b 2016-10-25 22:31:42 [cff] Correct cmap format reporting (#24819). * src/cff/cffdrivr.c (cff_get_cmap_info): Throw an error on synthetic charmap instead of guessing its format and language.
5081674c 2016-10-22 19:16:08 [truetype] Fix SCANTYPE instruction (#49394). * src/truetype/ttinterp.c (Ins_SCANTYPE): Only use lower 16bits.
57741403 2016-10-22 18:34:48 [sfnt] Improve handling of invalid post 2.5 tables [#49393]. * src/sfnt/ttpost.c (load_format_25): We need at least a single table entry.
7eeaf986 2016-10-14 08:58:17 [truetype] Fix handling of `cvar' table data. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=53 * src/truetype/ttgxvar.c (tt_face_vary_cvt): Ignore invalid CVT indices.
83702957 2016-10-13 22:52:40 URL updates.
9c54d124 2016-10-11 08:57:55 [psaux] Fix handling of invalid flex subrs. Problem reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=52 * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_callothersubr>: Set `flex_state' after error checking.
92281228 2016-10-11 07:12:12 * src/truetype/ttgxvar.c (tt_done_blend): Fix deallocation.
6b354931 2016-10-08 20:26:59 * src/cid/cidload.c (cid_face_open): Properly propagate `error'.
d61b0425 2016-10-08 19:20:33 [cid] Fix parsing of subr offsets. Bug introduced 2016-05-16. * src/cid/cidparse.c (cid_parser_new): Fix off-by-one error.
fcc0ee80 2016-10-01 20:12:25 [sfnt] Disable bitmap strikes if we don't have a bitmap data table. * src/sfnt/ttsbit.c (tt_face_load_sbit): Check whether we have a bitmap data table.
b0aacff4 2016-10-01 12:55:33 [smooth] Remove impossibility. * src/smooth/ftgrays.c (TWorker): Rearrange fields. (gray_convert_glyph): Remove impossible condition and clean up.
3576487a 2016-09-30 08:11:52 [pcf] Enrich family name with foundry name and glyph width info. This is a very old patch from openSuSE (from 2006, submitted to FreeType in 2011) that I forgot to apply. https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch Prepend the foundry name plus a space to the family name. There are many fonts just called `Fixed' which look completely different, and which have nothing to do with each other. When selecting `Fixed' in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. We also check whether we have `wide' characters; all put together, we get family names like `Sony Fixed' or `Misc Fixed Wide'. * src/pcf/pcfread.c (pcf_load_font): Implement it. * docs/CHANGES: Document it.
71b617d8 2016-09-29 19:53:39 [ftfuzzer] Speed up. * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Don't check for embedded bitmaps if we have a non-default instance.
bfa83bdc 2016-09-29 19:51:28 Comments.
2067c698 2016-09-29 19:49:07 [truetype] Disallow bitmap strokes for non-default instances. Also speed up access of default instances if GX variations are active. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `is_default_instance' member. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `is_default_instance'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Add test for default instance. (TT_Load_Glyph): Load embedded bitmaps for default instance only. * src/truetype/ttgxvar.c (TT_Set_MM_Blend): Compute `is_default_instance'.
