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 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 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.
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.
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.
Werner Lemberg 7e508242 2017-08-01T12:44:35 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
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.

Ben Wagner 7819aeb6 2017-06-28T22:57:41 Avoid Microsoft compiler warnings (#51331). While clang's sanitizer recommends a cast to unsigned for safe negation (to handle -INT_MIN), both MSVC and Visualc emit warning C4146 if an unsigned value gets negated. * include/freetype/internal/ftcalc.h (NEG_LONG, NEG_INT32), src/base/ftcalc.c (FT_MOVE_SIGN): Replace negation with a subtraction.
Alexei Podtelezhnikov 75cb071b 2017-06-21T22:52:37 [sfnt] Synthesize a Unicode charmap if one is missing. * src/sfnt/ttcmap.h (tt_cmap_unicode_class_rec): Declare it. * src/sfnt/ttcmap.c (tt_get_glyph_name, tt_cmap_unicode_init, tt_cmap_unicode_done, tt_cmap_unicode_char_index, tt_cmap_unicode_char_next, tt_cmap_unicode_class_rec): Implement synthetic Unicode charmap class. (tt_get_cmap_info): Make sure the callback is available. * src/sfnt/sfobjs.c (sfnt_load_face) [FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: If Unicode charmap is missing, synthesize one. * include/freetype/config/ftoption.h: Document it. * devel/ftoption.h: Ditto.
Werner Lemberg 79e3789f 2017-06-14T07:51:04 * src/winfonts/winfnt.c (FNT_Face_Init): Don't set active encoding. FreeType only sets a default active encoding for Unicode.
Werner Lemberg 96d26926 2017-06-09T20:34:28 Provide more macros for flooring, ceiling, and rounding. These versions don't produce run-time errors due to integer overflow. * include/freetype/internal/ftobjs.h: Include FT_INTERNAL_CALC_H. (FT_PAD_ROUND_LONG, FT_PAD_CEIL_LONG, FT_PIX_ROUND_LONG, FT_PIX_CEIL_LONG): New macros. (FT_PAD_ROUND_INT32, FT_PAD_CEIL_INT32, FT_PIX_ROUND_INT32, FT_PIX_CEIL_INT32): New macros.
Werner Lemberg faf34d29 2017-06-09T20:31:24 Remove unused macros. * include/freetype/internal/ftcalc.h (ADD_INT, SUB_INT, MUL_INT, NEG_INT): Deleted.
Werner Lemberg dcd8de27 2017-06-09T11:21:58 */*: Remove `OVERFLOW_' prefix. This increases readability.
Werner Lemberg c5a22541 2017-06-03T06:13:10 ftcalc.h: Avoid left-shift of negative numbers. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2055 * include/freetype/internal/ftcalc.h (INT_TO_F26DOT6, INT_TO_F2DOT14, INT_TO_FIXED, F2DOT14_TO_FIXED): Use multiplication.

Werner Lemberg e66d7300 2017-05-31T16:16:50 [cff] 32bit integer overflow run-time errors 2/2 (#46149). This commit handles the new engine. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT32, OVERFLOW_SUB_INT32, OVERFLOW_MUL_INT32, NEG_INT, NEG_LONG, NEG_INT32): New macros. * src/cff/cf2ft.c (cf2_getScaleAndHintFlag): Use OVERFLOW_ADD_INT32. * src/cff/cf2hints.c (cf2_getWindingMomentum, cf2_hint_init, cf2_hintmap_map, cf2_glyphpath_hintPoint, cf2_glyphpath_computeIntersection, cf2_glyphpath_computeOffset, cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): Use OVERFLOW_ADD_INT32, OVERFLOW_SUB_INT32, OVERFLOW_MUL_INT32, and NEG_INT32 where appropriate. * src/cff/cf2intrp.c (cf2_doFlex, cf2_doBlend, cf2_interpT2CharString): Ditto. Also add some other code where needed to avoid overflow.
Werner Lemberg fbe2fe4c 2017-05-29T13:29:28 Handle some integer overflow run-time errors (#46149, #48979). This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros.
Werner Lemberg 9d04fa70 2017-05-28T07:57:24 * include/freetype/internal/ftcalc.h (FLOAT_TO_FIXED): Remove. This macro is not used.
Alexei Podtelezhnikov ab2599ea 2017-05-20T00:35:21 [smooth] Implement minimal dynamic padding for LCD filtering. Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding. This change breakes current Skia (and Firefox). * include/freetype/internal/ftobjs.h (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic LCD padding.
Werner Lemberg e99b26aa 2017-05-14T21:57:27 Remove remnants of raster pool. * include/freetype/internal/ftobjs.h (FT_LibraryRec): Remove `raster_pool' and `raster_pool_size' fields. * src/base/ftobjs.c (FT_New_Library), src/raster/ftrend1.c (ft_raster1_init), src/smooth/ftsmooth.c (ft_smooth_init): Updated.

Werner Lemberg 5aa6716a 2017-04-22T13:27:21 Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. (FT_RENDER_MODE_SLIGHT): New render mode. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add `autohint_mode' and `autohint_metrics' fields. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): Updated. * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use `autohint_metrics'.
