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.
Werner Lemberg 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.

Werner Lemberg 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.
Werner Lemberg 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'.

John Tytgat 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.

suzuki toshiya 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.

suzuki toshiya 5c4e40d7 2017-09-09T00:59:33 [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

Werner Lemberg 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.
Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Werner Lemberg 587264cf 2017-08-23T09:14:14 Typo.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Werner Lemberg cadd29de 2017-08-16T13:32:17 * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.
Behdad Esfahbod 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.

Werner Lemberg 9f5783bb 2017-08-13T09:40:18 Minor.
Werner Lemberg 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.
Werner Lemberg e77ee789 2017-08-11T07:11:43 CHANGES: Minor update.
Werner Lemberg 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.
Werner Lemberg 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 5710ef98 2017-08-08T22:00:35 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.
Alexei Podtelezhnikov a9d8e90c 2017-08-08T21:42:37 * src/sftnt/ttpost.c (format): Use otspec-compliant versions.
Werner Lemberg 986a21b7 2017-08-06T06:35:19 CHANGES update suggested by Nikolaus.
Werner Lemberg 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.
Werner Lemberg 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.
Nikolaus Waxweiler 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.
Nikolaus Waxweiler 7f44c2db 2017-08-03T06:15:30 [truetype] Do not set any ClearType flags in v40 monochrome mode. This fixes weird behavior of instructions that resulted in rendering differences between v35 and v40 in monochrome mode, e.g., in `timesbi.ttf'. * src/truetype/ttinterp.c (Ins_GETINFO) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check `subpixel_hinting_lean'.
Werner Lemberg 7e508242 2017-08-01T12:44:35 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
Werner Lemberg e6b9b6ba 2017-08-01T09:34:24 Update CHANGES file.
Behdad Esfahbod 55bbb98f 2017-08-01T09:17:02 [truetype] Fix loading of named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position while loading the `avar' table.
Werner Lemberg ce367774 2017-08-01T08:24:51 [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1.
Werner Lemberg 933f4cbe 2017-07-26T23:32:32 [cff] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2738 * src/cff/cf2hints.c (cf2_glyphpath_computeOffset, cf2_glyphpath_curveTo): Use ADD_INT32.

Werner Lemberg fe0a7d9d 2017-07-13T10:25:42 [base] Fix memory leak. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=738362 * src/base/ftglyph.c (FT_Get_Glyph): Do proper deallocation in case of error.
Werner Lemberg 134de096 2017-07-12T22:16:37 [base] Integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2573 * src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics): Use FT_PIX_CEIL_LONG and FT_PIX_ROUND_LONG.
Werner Lemberg b5cab5c9 2017-07-12T21:58:35 Document how to scale manually.
Werner Lemberg 229a5535 2017-07-12T10:48:41 CHANGES: Add information on global metrics rounding. I missed to add this important information.
Werner Lemberg 3d083fc2 2017-07-12T00:24:48 * src/truetype/ttpload.c (tt_face_get_location): Off-by-one typo. Also improve tracing message. Problem reported as https://bugs.chromium.org/p/chromium/issues/detail?id=738919
