b9bd2d14	2017-11-22T12:32:47	[psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code.
954710dd	2017-11-15T23:06:29	* include/freetype/ftrender.h: Fix `FT_Renderer_RenderFunc' type.
dff40d03	2017-10-12T18:13:21	Add T1_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old Type 1 engine gets compiled into FreeType. It is disabled by default. * devel/ftoption.h, include/freetype/config/ftoption.h (T1_CONFIG_OPTION_OLD_ENGINE): New macro. * include/freetype/internal/psaux.h (PS_Decoder): Remove unused field. * include/freetype/internal/psaux.h, src/cid/cidgload.c (cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c (ps_builder_add_point), src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph, t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h, src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround relevant code with macro. Minor code changes.
78df3c27	2017-10-12T18:13:08	Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine.

7bfcaaca	2017-10-07T13:14:38	[sfnt] Adjust behaviour of PS font names for variation fonts. * src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Use a named instance's PS name only if no variation is applied.
f89c67f0	2017-10-07T13:10:53	[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance. (TT_Set_Var_Design): Use current named instance for default coordinates. * src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.
8c92f762	2017-10-07T12:12:49	Make `FT_FACE_FLAG_VARIATION' work. * include/freetype/internal/tttypes.h (TT_Face): Remove `is_default_instance'; this can be replaced with a combination of `FT_IS_VARIATION' and `FT_IS_INSTANCE'. * src/cff/cffdrivr.c (cff_get_advances): Updated. * src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/sfobjs.c (sfnt_init_face): Updated. * src/truetype/ttdriver.c (tt_get_advances), src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph, IS_DEFAULT_INSTANCE), src/truetype/ttgxvar.c (tt_set_mm_blend): Updated. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Handle `FT_FACE_FLAG_VARIATION'. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design): Handle `FT_FACE_FLAG_VARIATION'.

1df35d94	2017-10-04T22:46:36	[cff] Add support for `FSType'. * include/freetype/internal/cfftypes.h (CFF_FontRec): Add `font_extra' entry. * src/cff/cffdrivr.c (cff_ps_get_font_extra): New function to retrieve FSType info from the embedded PostScript data. (cff_service_ps_info): Register function. * src/cff/cffload.c (cff_font_done): Free `font_extra'.
2127f076	2017-09-30T16:16:03	[include] Whitespace.
c26f7f97	2017-09-29T00:13:19	Bitmap metrics presetting [2/2]. * src/base/ftobjs.c (FT_Load_Glyph): Preset the bitmap metrics when appropriate but `FT_Render_Glyph' is not called. * include/freetype/freetype.h (FT_GlyphSlotRec): Document the change.
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'.

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.
7e185dcd	2017-09-25T06:40:32	Allow `type1' module to use the Adobe engine.

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.
0589e3c0	2017-09-25T06:10:20	Use the new objects. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Fix switching between new and old engines. * src/cff/cffgload.c, src/cff/cffparse.c: Update calls. * src/psaux/psblues.c, src/psaux/psfont.c, src/psaux/psfont.h, src/psaux/psft.c, src/psaux/psft.h, src/psaux/psintrp.c: Update all to use new objects.
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.

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.

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.

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.
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.
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.

Also add some other code where needed to avoid overflow.
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.

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.

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'.

[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.

[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.

[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.

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.

[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.

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'.
