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'.
12ae57d9	2017-09-26T12:53:41	Copyright notices, formatting, whitespace, minor doc fixes.
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.
6e7da50b	2017-09-25T08:29:38	Documentation fixes.
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.
ebb1735a	2017-09-25T08:26:57	Move `psdecode' into `psobjs'. As the former only contains a single procedure, move it into `psobjs' for simplicity. Also change the parameter order to the conventional one. * src/psaux/psdecode.c (ps_decoder_init): Moved to... * src/psaux/psobjs.c: ...Here. * src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto. * include/freetype/internal/psaux.h (PSAux_ServiceRec): Update `ps_decoder_init' function signature. * src/cff/cffgload.c, src/cid/cidgload.c, src/type1/t1gload.c: Update calls. * src/psaux/psaux.c, src/psaux/psauxmod.c: Update includes. * src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRV_SRC): Update file references.
7e185dcd	2017-09-25T06:40:32	Allow `type1' module to use the Adobe engine. Add the callback and some conditionals to switch between the two engines. * include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change function declarations. * src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the callbacks. * src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for number conversion. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code to choose which renderer to use. * src/cid/cidgload.c (cid_load_glyph): Update call. * src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update includes.
97704b15	2017-09-25T06:33:28	Add Adobe engine configuration. Use the previously changed PS_Driver in type1 module to store hinting engine configuration. * include/freetype/ftt1drv.h: New file. 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.
645d1b86	2017-09-25T06:28:25	Move and rename `CFF_Driver'. 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.
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.

Introduce `PS_Decoder' and `PS_Builder' which include all fields from either Type 1 or CFF decoders/builders. * include/freetype/internal/psaux.h (PS_Builder, PS_Decoder): New structs. * src/psaux/psobjs.c, src/psaux/psobjs.h: Add `PS_Builder' functions. * src/psaux/psdecode.c, src/psaux/psdecode.h: New files to hold `PS_Decoder' initialization functions. * src/psaux/psaux.c, src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRV_SRC): Updated.
b624868b	2017-09-24T22:32:40	Move `cff_random' into `psaux' service. NOTE: Does not compile! Minor fix to allow both `cff' and `psaux' to use `cff_random'. * src/cff/cffload.c (cff_random): Move to... * src/psaux/psobjs.c: Here. * src/cff/cffload.h: Move corresponding declaration to `src/psaux/psobjs.h'. * include/freetype/internal/psaux.h (PSAux_ServiceRec): Register the function here... * src/psaux/psauxmod.c: And here. * src/cff/cffload.c, src/psaux/cf2intrp.c: Update code.
df11628b	2017-09-24T22:28:07	Move struct declarations to `freetype/internal'. NOTE: Does not compile! This is so that the CFF functions moved to `psaux' can access the same structs that they need. * src/cff/cfftypes.h: Moved to... * include/freetype/internal/cfftypes.h: ...Here. * src/cff/cffobjs.h: Moved the struct declarations to... * include/freetype/internal/cffotypes.h: ... this new file. * include/freetype/internal/internal.h (FT_INTERNAL_CFF_TYPES_H, FT_INTERNAL_CFF_OBJECT_TYPES_H): New macros. * src/cff/cffcmap.h, src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffgload.h, src/cff/cffload.h, src/cff/cffobjs.c, src/cff/cffobjs.h, src/cff/cffparse.h, src/psaux/psobjs.h, include/freetype/internal/psaux.h, include/freetype/internal/services/svcfftl.h: Update includes. * src/cff/rules.mk (CFF_DRV_H): Updated.
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.
edacde60	2017-09-24T22:20:38	Add new service for inter-module calls. NOTE: Does not compile! This is to allow CFF functions moved to `psaux' to call functions declared in `src/cff/cffload.h'. * include/freetype/internal/services/svcfftl.h: New file, setting up a `CFFLoad' service. * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC10, FT_DEFINE_SERVICEDESCREC): New macros. (FT_SERVICE_CFF_TABLE_LOAD_H): New macro. * src/cff/cffdrivr.c, src/cff/cffpic.h: Register the new service. * src/cff/cfftypes.h (CFF_FontRec), src/psaux/cf2font.h (CF2_FontRec): Add service interface. * src/cff/cffobjs.c, src/psaux/cf2font.c, src/psaux/cf2ft.c, src/psaux/cf2intrp.c, src/psaux/cffdecode.c: Use the new service.
9578e07a	2017-09-24T22:05:32	Add callbacks for inter-module calls. NOTE: Does not compile! * include/freetype/internal/psaux.h: Add function pointer declarations. * src/psaux/cffdecode.c (cff_decoder_init): Update to take in callbacks. * src/psaux/cffdecode.h: Ditto. * src/cff/cffgload.c (cff_compute_max_advance, cff_slot_load): Update calls to pass in callbacks. * src/psaux/cf2ft.c, src/psaux/cffdecode.c: Use them.

33b390a6	2017-09-08T21:34:47	Warping documentation updates.
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. 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.
7e508242	2017-08-01T12:44:35	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
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.
b5cab5c9	2017-07-12T21:58:35	Document how to scale manually.
762de5e2	2017-07-06T22:31:57	Tweak suggested use of `lsb_delta' and `rsb_delta'.
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.
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.
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.
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.
faf34d29	2017-06-09T20:31:24	Remove unused macros. * include/freetype/internal/ftcalc.h (ADD_INT, SUB_INT, MUL_INT, NEG_INT): Deleted.
dcd8de27	2017-06-09T11:21:58	/: Remove `OVERFLOW_' prefix. This increases readability.
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.

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.

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.

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'. (af_loader_load_glyph): s/internal/slot_internal/. Initialize `autohint_metrics' and `autohint_mode' depending on current auto-hint mode. Use `autohint_metrics'. Updated. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. * src/base/ftobjs.c (FT_Load_Glyph): Updated.
