ec7d2e5f	2017-09-28T14:21:34	* src/psaux/psintrp.c (cf2_doStems): Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3510
97cd1265	2017-09-28T08:29:33	* src/cid/cidgload.c (cid_slot_load_glyph): Fix memory leak. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3489
61d1818b	2017-09-28T00:20:50	Bitmap metrics presetting [1/2]. This mainly just extracts the code for presetting the bitmap metrics from the monochrome, grayscale, and LCD renderers into a separate function. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that calculates prespective bitmap metrics for the given rendering mode. * include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap): Declare it. * src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds padding to CBox taking into account pecularities of LCD rendering. * include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it. * src/raster/ftrend1.c (ft_raster1_render): Reworked to use `ft_glyphslot_preset_bitmap'. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto. (ft_smooth_render_lcd, ft_smooth_render_lcd): The pixel_mode setting is moved to `ft_glyphslot_preset_bitmap'.
dd40d10e	2017-09-28T10:42:23	Fix compiler warning. * src/psaux/pshints.c (cf2_hintmap_dump): Add switch for tracing code.
693a1181	2017-09-27T08:42:50	* src/sfnt/ttload.c (tt_face_load_font_dir): Fix compiler warning.

6eb03f8f	2017-09-25T06:49:41	Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.
cb3f4c61	2017-09-25T06:44:51	Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'. This is the context for the interpreter and since it is currently stored in `CFF_Font', is unavailable in Type 1 mode. * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New `cf2_instance' field. * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to `PS_Decoder'. * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses.
a5c02f49	2017-09-25T08:11:32	Add Adobe engine configuration. This is similar to what was done in the `type1' module. * src/cid/cidriver.c (t1cid_driver_class): Update declaration. * src/cid/cidobjs.c: Include FT_TYPE1_DRIVER_H. (cid_driver_init): Update code.
7e185dcd	2017-09-25T06:40:32	Allow `type1' module to use the Adobe engine.

Duplicate and rename config options from CFF. * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. * src/type1/t1driver.c (t1_driver_class): Update declaration. * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. (T1_Driver_Init): Update code.
4cdbac05	2017-09-25T09:05:00	Fix compiler warnings. * src/psaux/psft.c (cf2_initLocalRegionBuffer): Remove redundant test. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escCALLOTHERSUBR>: Add casts. * src/psaux/psobjs.c (ps_decoder_init): Add cast.
93e3cffd	2017-09-25T08:08:21	Change subfont synthesis for CID fonts. Change `t1_make_subfont' to take in the Private dict record as an argument. This is because Type 1 and CID font records in FreeType have this in different places. * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to `FT_Face' so that CID is also accepted. Take `PS_Private' as an argument and let caller figure out where the Private dict actually is. Update references. * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update declaration. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update call.
645d1b86	2017-09-25T06:28:25	Move and rename `CFF_Driver'.

d23affe1	2017-09-25T06:22:52	Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes.
e28550af	2017-09-25T08:05:19	Switch to Adobe engine. * src/type1/t1objs.c (T1_Driver_Init): Set default to Adobe engine.
9428ee42	2017-09-25T06:15:46	Prepare for Type 1 mode.

a1a6a1f6	2017-09-25T08:31:52	Minor fixes. * include/freetype/internal/psaux.h, src/psaux/psobjs.{c,h}: Rearrange `ps_builder_init' arguments to conventional order. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Add a check and notice for `SubFont' in Type 1 mode.
d813b5da	2017-09-25T08:04:09	Extend Adobe interpreter (seac). This concludes the changes needed to add Type 1 support. * src/psaux/psintrp.c: Update includes. (cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to implied seac for CFF. * src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New function to look up the glyph index. * src/psaux/psft.c (cf2_getT1SeacComponent, cf2_freeT1SeacComponent): New functions to get the charstrings for seac components. * src/psaux/t1decode.h, src/psaux/psft.h: Update declarations.
43c01582	2017-09-24T23:00:36	Objects for new interpreter (part 2). Make the new objects copy over values. They are essentially wrapper types for the different decoders/builders. * include/freetype/internal/psaux.h: Update declarations. (PS_Builder): Add `is_t1' flag. (PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to... (CFF_Decoder_{Get,Free}_Glyph_Callback: ... this. (PS_Decoder): Updated. Add `t1_parse_callback' member. (PSAux_ServiceRec): Add `ps_decoder_init' member. * src/psaux/psdecode.h, src/psaux/psobjs.h: Update declarations. * src/psaux/psdecode.c, src/psaux/psobjs.c: Implement copy with two modes. * src/psaux/psauxmod.c: Add builder and decoder functions to `PSAux' service.
eba54c28	2017-09-24T22:49:56	Add objects for new interpreter.

This is to avoid closing the current contour.
766f529a	2017-09-24T22:40:07	Rename files. Replace the `cf2' file name prefix with `ps' as the Adobe engine will be used for both PostScript Types 1 and 2 (CFF) instead of just CFF. s/cf2/ps/ for all following. * src/psaux/cf2: Rename files. src/psaux/: Update includes. src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRC_SRC, PSAUX_DRV_H): Update file references.
8a1b5c0c	2017-09-24T22:35:47	Minor fix. Use `MultiMasters' service in `psaux' instead of a call to `cff'. The project builds if CFF_CONFIG_OPTION_OLD_ENGINE is not defined. * src/psaux/cf2ft.c: Update includes. (cf2_getNormalizedVector): Use `mm->get_var_blend' instead of `cff_get_var_blend'.
96682559	2017-09-25T07:54:02	Extend Adobe interpreter (callothersubr). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escCALLOTHERSUBR>: Copy code from `t1_decoder_parse_charstrings' (in `t1decode.c').

Type 1 requires large integers to be followed by `div'; cf. `Adobe Type 1 Font Format', section 6.2. <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is to ensure `div' and `callsubr' get values they can use.
705bbe7c	2017-09-24T21:39:20	Move CFF decoder components into `psaux' module. NOTE: Does not compile! * src/cff/cffgload.c (CFF_Operator, CFF_COUNT_{CHECK_WIDTH,EXACT,CLEAR_STACK}, cff_argument_counts, cff_operator_seac, cff_compute_bias, cff_lookup_glyph_by_stdcharcode, cff_decoder_{parse_charstrings,init,prepare}): Move to... * src/psaux/cffdecode.c: This new file. * src/cff/cffgload.h: Move corresponding declarations to... * src/psaux/cffdecode.h: This new file. * src/cff/cffgload.h (CFF_MAX_{OPERANDS,SUBRS_CALLS,TRANS_ELEMENTS}, CFF_Decoder_Zone, CFF_Decoder): Move declarations to... * include/freetype/internal/psaux.h: Here. * src/psaux/cf2ft.h: Update include. * src/psaux/psaux.c, src/psaux/rules.mk (PSAUX_DRV_SRC): Update with the new file.
d52dd7f3	2017-09-25T08:22:26	Fix Type 1 hinting. Type 1 hinting breaks sometimes when mid-charstring hints should have been in the initial hintmap. This fix adds a preprocessing pass that reads all hints and builds the correct initial hintmap first, before proceeding to build the glyph outline. * src/psaux/psintrp.c (cf2_interpT2CharString): New `initial_map_ready' boolean flag. Ignore outline commands and hint changes on first pass. <cf2_cmdENDCHAR>: Add section to build hintmap and rewind.
81b86c45	2017-09-25T07:14:18	Extend Adobe interpreter (hstem, vstem, hstem3, vstem3). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode.

999a75b6	2017-09-25T08:16:59	Minor fixes. * src/psaux/psintrp.c (cf2_interpT2CharString): Fix check for pop results. s/font->decoder/decoder/ where necessary. <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_escHSTEM3, cf2_escVSTEM3>: Use offset parameter in `cf2_doStems' instead of doing correction for left-sidebearing.
37ed70f6	2017-09-25T06:59:26	Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum. (cf2_interpT2CharString): Copy relevant code over from `t1_decoder_parse_charstrings' (in `t1decode.c').
283ef285	2017-09-25T06:54:16	Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.

0d1262a4	2017-09-24T17:36:47	[sfnt] Fix `premultiply_data' (#52092). * src/sfnt/pngshim.c (premultiply_data): Don't use vector extension if we have less than 16 bytes of data.
e7202069	2017-09-24T09:16:39	Minor.
6d403d08	2017-09-24T09:06:01	Fix handling of ValueRecords. For GPOS pair positioning format 1 the description of ValueRecords in the OpenType specification (1.8.2, from today) is wrong – the offset has to be taken from the parent structure; in this case the `PairSet' table. * src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'. (otv_PairPos_validate): Adjust.
0da0faf0	2017-09-24T09:13:41	[otvalid] Handle `GSUB' and `GPOS' v1.1 tables. * src/otvalid/otvgsub.c (otv_GSUB_validate), src/otvalid/otvgpos.c (otv_GPOS_validate): Implement it.
2b79d25f	2017-09-23T10:29:26	[otvalid] Update common table handling to OpenType 1.8.2. * src/otvalid/otvcommn.c (otv_Device_validate): Handle VariationIndex subtable. (otv_Lookup_validate): Handle MarkFilteringSet.
e7ac8e40	2017-09-23T14:04:49	[build] Windows-style DLL versioning. * build/windows/ftver.rc: New VERSIONINFO resource. * build/windows/vc2010/freetype.vcxproj: Further improvements.
63be40bc	2017-09-23T00:44:59	[truetype] Really fix #52082. * src/truetype/ttinterp.c (Ins_MDRP): Correct conditional.
b0103677	2017-09-23T00:40:28	[otvalid] Handle `GDEF' v1.2 and v1.3 tables. No validation of variation stuff yet. * src/otvalid/otvgdef.c (otv_MarkGlyphSets_validate): New function. (otv_GDEF_validate): Implement it.
6756a185	2017-09-23T00:36:49	[otvalid] Handle `BASE' v1.1 table. No validation of variation stuff yet. * src/otvalid/otvbase.c (otv_BASE_validate): Implement it.
3645982a	2017-09-22T07:53:25	[otvalid] Macros for 32bit offset support. * src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE32, OTV_OPTIONAL_OFFSET32, OTV_SIZE_CHECK32): New macros.
3be8e347	2017-09-21T23:12:59	[build] Simplify Visual C++ 2010 project. * build/windows/vc2010/freetype.vcxproj: Remove fake singlethreaded configurations and tweak.
6d04bd99	2017-09-21T21:22:51	[truetype] Integer overflow (#52082). * src/truetype/ttinterp.c (Ins_MDRP): Avoid FT_ABS.
cf64e338	2017-09-21T11:42:48	[sfnt] Fix postscript name for default instance of variation fonts. Problem reported by Behdad. * src/sfnt/sfdriver.c (sfnt_get_ps_name): Test `is_default_instance'.
b19cdc9c	2017-09-21T11:02:35	[truetype] Fix `mmvar' array pointers, part 2. The previous commit was incomplete. * src/truetype/ttgxvar.c: Properly initialize sub-array offsets for `master' also.
3b3cb32d	2017-09-21T09:03:20	[truetype] Fix `mmvar' array pointers. Without this change, clang's AddressSanitizer reports many runtime errors due to misaligned addresses. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use multiples of pointer size for sub-array offsets into `mmvar'.
eaa9adf3	2017-09-20T08:00:05	[truetype] Integer overflows. Changes triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3429 * src/truetype/ttinterp.c (Ins_SHPIX, Ins_DELTAP): Use NEG_LONG. (Ins_MIAP): Use SUB_LONG.
74f44239	2017-09-19T23:41:27	[build] Fix DLL builds in Visual C++ project. * build/windows/vc2010/freetype.vcxproj: Use DynamicLibrary in Debug and Release configurations. * include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF) [_DLL]: Use Visual C++ extensions.
b00be9f6	2017-09-19T07:12:03	[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
8b0d2e9e	2017-09-18T22:54:49	[build] Declutter Visual C++ 2010-2017 project. * build/windows/vc2010/freetype.vcxproj: Use MaxSpeed (/02) optimization for Release configuration throughout the project.
39ce3ac4	2017-09-16T19:08:17	* Version 2.8.1 released. ========================= Tag sources with `VER-2-8-1'. * docs/VERSION.TXT: Add entry for version 2.8.1. * docs/CHANGES: Updated. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, 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/2.8/2.8.1/, s/28/281/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 21:0:15. * CMakeLists.txt (VERSION_PATCH): Set to 1.
c28e9c9b	2017-09-15T22:23:01	Typos.
b757ddb1	2017-09-13T22:17:03	[sfnt] lowest gcc for vectors ( e1d0249e ) is changed to 4.7. __builtin_shuffle() was introduced in gcc-4.7. The lowest gcc to enable vector operation is delayed from 4.6 to 4.7. * src/sfnt/pngshim.c (premultiply_data): Fix cpp-macro to enable the vector operation, to change the lowest gcc version from 4.6 to 4.7.
5ad84577	2017-09-13T15:49:15	[cache] Fix a possible overflow by signed integer comparison. Improve the code by 5d3ff05615dda6d1325ed612381a17a0df04c975 , issues are found by Behdad Esfahbod and Werner Lemberg. * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Replace a subtraction to check higher bit by a bit operation, and cpp-conditionalize for appropriate systems. Add better documentation to the comment. (FTC_ImageCache_LookupScaler): Ditto. (FTC_SBitCache_Lookup): Ditto. (FTC_SBitCache_LookupScaler): Ditto.
96dcc8ad	2017-09-13T08:16:23	[autofit] Really fix #41334 (#52000). * src/autofit/aflatin.c (af_latin_hints_compute_segments): Set `segment->delta' everywhere.
21658c31	2017-09-12T15:59:18	[autofit, sfnt] Fix for `make multi'. * src/autofit/afshaper.c: Include FT_ADVANCE_H, to use FT_Get_Advance() in it. * src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H to use PS_Unicodes in it, also include `ttpost.h' to use tt_face_get_ps_name() in it.
babe13ec	2017-09-11T10:47:29	[build] Improve builds with different MS Visual Studio versions. * builds/windows/vc2010/freetype.vcxproj: Switch platform toolset according to the Visual Studio version.
3e4b7997	2017-09-11T08:51:44	* src/sfnt/ttkern.c (tt_face_load_kern): Reject format 2 tables. Reported by Behdad.
0ab2b62d	2017-09-09T08:08:47	[autofit] Improve communication with ftgrid. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Provide values in font units.
3ef59e59	2017-09-09T01:28:24	[base] Remove a check for resource ID in the resource fork driver. LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format.
71f66180	2017-09-09T01:05:44	ChangeLog for last commit.
a3dd6d99	2017-09-05T23:02:04	Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it.
7d017ba8	2017-09-05T15:28:21	[bdf] Fix size and resolution handling. * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are missing. * docs/CHANGES: Document it.
f0898b92	2017-08-25T21:40:01	Swap `ALLOC_MULT' arguments (#51833). * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Updated. * src/raster/ftrend1.c (ft_raster1_render): Updated.
587264cf	2017-08-23T09:14:14	Typo.
e1d0249e	2017-08-23T08:18:22	[sfnt] Fix clang compilation (#51788). * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of scalars. (vector_shuffle): New macro to take of a different built-in function name on clang.
bd28952e	2017-08-22T08:41:03	[base] Don't zero out allocated memory twice (#51816). Patch applied from bug report. * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to avoid unnecessary overhead.
0aca17cf	2017-08-22T08:25:14	[truetype] Integer overflow. Changes triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use NEG_LONG.
7653c765	2017-08-17T21:28:32	[sfnt] Avoid synthetic unicode for symbol fonts with PUA. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=754574 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL.
cadd29de	2017-08-16T13:32:17	* src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.
c9d7c03f	2017-08-15T08:48:17	[sfnt] Speed up PNG image loading. This reduces the overhead of `premultiply_data' by 60%. * src/sfnt/pngshim.c (premultiply_data): Provide code which uses gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a time.
b45043c4	2017-08-11T09:34:20	[sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available.
f2e121ab	2017-08-10T12:56:50	[base] Minor API improvement for default variation axis setting. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. * docs/CHANGES: Updated.
c87fec02	2017-08-09T07:45:12	[psnames] Really fix issue #49949. We now use a separate preprocessor macro to handle both definition and declaration of the glyph name arrays. * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. (dump_encoding): Ditto. (main): Use `wb' mode for writing the output file, which works on Windows also. * src/psnames/pstables.h: Regenerated.
410f3799	2017-03-09T00:08:38	[smooth] Harmony LCD rendering. This is a new technology for LCD-optimized rendering. It capitalizes on the fact that each color channel grid is shifted by a third of a pixel. Therefore it is logical to render 3 separate monochrome bitmaps shifting the outline by 1/3 pixel, and then combine them. Importantly, the resulting output does not require additional LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized rendering. * include/freetype/ftlcdfil.h, include/freetype/freetype.h, include/freetype/config/ftoption.h, devel/ftoption.h: Updated documentation.
5710ef98	2017-08-08T22:00:35	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.
a9d8e90c	2017-08-08T21:42:37	* src/sftnt/ttpost.c (format): Use otspec-compliant versions.
17196b7c	2017-08-05T18:58:34	[truetype] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2868 * src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG.
f43b3094	2017-08-05T18:22:17	[base, truetype] New function `FT_Get_Var_Axis_Flags'. The reserved `flags' field got a value in OpenType version 1.8.2; unfortunately, the public `FT_Var_Axis' structure misses the corresponding element. Since we can't add a new field, we add an access function. * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory of `mmvar' to hold axis flags. Fill the axis flags array. * docs/CHANGES: Updated.
24e256ab	2017-08-04T08:25:31	[truetype] Fix metrics of B/W hinting in v40 mode. Phantom points are now saved outside v40 backwards compatibility mode. This fixes the jumping glyphs when switching between v35 and v40 monochrome mode. * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.

2017-09-28T22:59:31

[smooth, raster] Miscellaneous cleanups. * src/raster/ftrend1.c (ft_raster1_render): Clean up the exit. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Reduce translations and clean up the exit. (ft_smooth_render_lcd, ft_smooth_render_lcd): Remove unused `error'..

2017-09-28T00:20:50

Bitmap metrics presetting [1/2]. This mainly just extracts the code for presetting the bitmap metrics from the monochrome, grayscale, and LCD renderers into a separate function. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that calculates prespective bitmap metrics for the given rendering mode. * include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap): Declare it. * src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds padding to CBox taking into account pecularities of LCD rendering. * include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it. * src/raster/ftrend1.c (ft_raster1_render): Reworked to use `ft_glyphslot_preset_bitmap'. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto. (ft_smooth_render_lcd, ft_smooth_render_lcd): The pixel_mode setting is moved to `ft_glyphslot_preset_bitmap'.

6eb03f8f

2017-09-25T06:49:41

Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.

cb3f4c61

2017-09-25T06:44:51

Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'. This is the context for the interpreter and since it is currently stored in `CFF_Font', is unavailable in Type 1 mode. * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New `cf2_instance' field. * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to `PS_Decoder'. * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses.

93e3cffd

2017-09-25T08:08:21

Change subfont synthesis for CID fonts. Change `t1_make_subfont' to take in the Private dict record as an argument. This is because Type 1 and CID font records in FreeType have this in different places. * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to `FT_Face' so that CID is also accepted. Take `PS_Private' as an argument and let caller figure out where the Private dict actually is. Update references. * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update declaration. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update call.

645d1b86

This is so that we can use the same hinting engine parameters for Type 1. * include/freetype/internal/cffotypes.h (CFF_Driver): Rename and move to... * include/freetype/internal/psaux.h (PS_Driver): ...here. * src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cff/cffobjs.h, src/psaux/psft.c, src/psaux/psobjs.c: Update references.

d23affe1

2017-09-25T06:22:52

Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes.

2017-09-25T08:22:26

Fix Type 1 hinting. Type 1 hinting breaks sometimes when mid-charstring hints should have been in the initial hintmap. This fix adds a preprocessing pass that reads all hints and builds the correct initial hintmap first, before proceeding to build the glyph outline. * src/psaux/psintrp.c (cf2_interpT2CharString): New `initial_map_ready' boolean flag. Ignore outline commands and hint changes on first pass. <cf2_cmdENDCHAR>: Add section to build hintmap and rewind.

2017-09-25T06:59:26

Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum. (cf2_interpT2CharString): Copy relevant code over from `t1_decoder_parse_charstrings' (in `t1decode.c').

[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

[base] Remove a check for resource ID in the resource fork driver. LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format.

Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it.

[sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available.

[psnames] Really fix issue #49949. We now use a separate preprocessor macro to handle both definition and declaration of the glyph name arrays. * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. (dump_encoding): Ditto. (main): Use `wb' mode for writing the output file, which works on Windows also. * src/psnames/pstables.h: Regenerated.

[smooth] Harmony LCD rendering. This is a new technology for LCD-optimized rendering. It capitalizes on the fact that each color channel grid is shifted by a third of a pixel. Therefore it is logical to render 3 separate monochrome bitmaps shifting the outline by 1/3 pixel, and then combine them. Importantly, the resulting output does not require additional LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized rendering. * include/freetype/ftlcdfil.h, include/freetype/freetype.h, include/freetype/config/ftoption.h, devel/ftoption.h: Updated documentation.

[base, truetype] New function `FT_Get_Var_Axis_Flags'. The reserved `flags' field got a value in OpenType version 1.8.2; unfortunately, the public `FT_Var_Axis' structure misses the corresponding element. Since we can't add a new field, we add an access function. * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory of `mmvar' to hold axis flags. Fill the axis flags array. * docs/CHANGES: Updated.
