Alexei Podtelezhnikov d71f2bc1 2018-10-26T22:52:25 Revert "Align FreeType with standard C memory management." This reverts commit 877aa1b2cc662978aae61ed4d5c6ea8ba56b2fe7.
Alexei Podtelezhnikov 877aa1b2 2018-09-27T21:17:36 Align FreeType with standard C memory management. * include/freetype/ftsystem.h: Include FT_TYPES_H. (*FT_Alloc_Func, *FT_Realloc_Func): Use size_t for the size arguments. * src/raster/ftmisc.h: Ditto. * builds/amiga/src/base/ftsystem.c, builds/unix/ftsystem.c, * builds/vms/ftsystem.c, src/base/ftsystem.c (ft_alloc, ft_realloc): Use size_t for the size arguments. * src/base/ftdbgmem.c (ft_mem_debug_alloc, ft_mem_debug_realloc): Use FT_Offset, aka size_t, for the size arguments.
Alexei Podtelezhnikov 4500c701 2018-09-26T22:04:50 Typo.
Werner Lemberg a9af6914 2018-09-25T09:10:09 Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
Alexei Podtelezhnikov 793a9ff9 2018-09-22T14:38:00 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Another tweak. This one should be clearer. When the rounded monochrome bbox collapses we add a pixel that covers most if not all original cbox.
Alexei Podtelezhnikov f26d5775 2018-09-21T20:34:58 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Further tweak.
Ben Wagner 335528e1 2018-09-21T11:26:37 Improve auto-hinter handling of bitmap fonts (#54681). For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines. The current test for using the auto-hinter in `FT_Load_Glyph' checks if the driver supports scalable outlines, but not if the face supports scalable outlines. * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have scalable outlines.
Werner Lemberg 493aa68f 2018-09-21T08:32:22 [base] Some comments.
Alexei Podtelezhnikov 2a9850c4 2018-09-20T22:40:32 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Tiny rounding tweak. This adds pixels in case a contour goes through the center and they need to be turned on in the b/w rasterizer.
Werner Lemberg 8e950680 2018-09-20T06:26:34 [base] Remove unused function `FT_GlyphLoader_CopyPoints'. * include/freetype/internal/ftgloadr.h, src/base/ftgloadr.c (FT_GlyphLoader_CopyPoints): Do it.
Werner Lemberg 9be656bb 2018-09-01T11:01:52 Remove `FT_Outline_{New,Done}_Internal'. These public API functions(!) were always undocumented and have escaped all clean-up efforts until now. * include/freetype/ftoutln.h (FT_Outline_New_Internal, FT_Outline_Done_Internal): Removed. * src/base/ftoutln.h (FT_Outline_New_Internal, FT_Outline_Done_Internal): Merge into... (FT_Outline_New, FT_Outline_Done): ... these functions. * docs/README: Updated.

Werner Lemberg 8f09eb5c 2018-07-17T21:45:24 Allow FT_ENCODING_NONE for `FT_Select_Charmap'. This is a valid encoding tag for BDF, PCF, and Windows FNT, and there is no reason to disallow it for these formats. * src/base/ftobjs.c (FT_Select_Charmap): Implement it.
Werner Lemberg 9f15370e 2018-07-12T07:31:26 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Init `cbox'. Taken from patch #9667, written by Steve Langasek <vorlon@debian.org>. This fixes a build failure (most probably a bug in gcc) on ppc64el when building with -O3.

Nikhil Ramakrishnan 78d85b9c 2018-06-04T18:42:29 Restore missing comment lines and other minor fixes
Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.
Werner Lemberg ae2cd1b7 2018-05-30T09:34:57 Various minor color fixes. * include/freetype/config/ftheader.h (FT_COLOR_H): New macro. * include/freetype/internal/ftobjs.h (FT_Colr_Internal): Change type of `load_flags' to `FT_Int32'. * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func): Change type of `idx' to `FT_UInt'.

Alexei Podtelezhnikov 7b73cb07 2018-05-24T22:38:24 [smooth] Formalize Harmony LCD rendering. This generalizes magic outline shifts that make Harmony LCD rendering work in terms of precise two-dimensional RGB subpixel positions. These coordinates are now set in time of the `smooth' module initialization and later used to shift a glyph outline for rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same coordinates. The letter, however, rotates them before using. The LCD bitmap padding is also calculated using these coordinates. * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field `lcd_geometry'. * src/base/ftlcdfil.c (ft_lcd_padding): Reworked. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly. * src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING] (ft_smooth_init): Initialize `lcd_geometry'. (ft_smooth_render_generic): Formalize outline shifts.

(FT_Glyph_Layer): New typedef. Update code to use it where appropriate. * src/base/ftobjs.c (FT_Get_GlyphLayers): New function.
Alexei Podtelezhnikov f1458d2e 2018-05-15T21:47:18 [base] Fix mono bitmap presetting (#53896). It is rather fundamental to set monochrome bitmap based on rounded CBox because the b/w rasterizer turns on pixels when their centers are inside the glyph outline. The dropout control is unpredictable and can distort narrow glyphs if the bitmap is too wide. Reported by Chris Liddell. * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries are too close, adjust them before rounding.
Werner Lemberg 5fd12564 2018-05-15T11:30:49 Grammar fixes.
Werner Lemberg 2dd20916 2018-05-15T09:05:53 [sfnt] If `COLR' is present, don't assume that all glyphs use it. * src/sfnt/ttcolr.c (tt_face_load_colr_layers): Return FT_Err_Ok if current glyph is not a `COLR' base glyph. * src/truetype/ttgload.c (TT_Load_Glyph): Don't allocate `color_layers' if there are no color layers.
Werner Lemberg 06820637 2018-05-14T09:45:16 * src/base/ftobjs.c (FT_Load_Glyph): Fix signature of `pixel_modes'.
Werner Lemberg c5a8a535 2018-05-14T09:42:20 Provide dummy functions if `TT_CONFIG_OPTION_SFNT_NAMES' is not set. * src/base/ftsnames.c [!TT_CONFIG_OPTION_SFNT_NAMES]: Implement it.

Shao Yu Zhang f04d8175 2018-05-13T03:25:09 [sfnt] Preliminary support of coloured layer outlines. This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

Nikolaus Waxweiler a364e38a 2017-11-14T07:54:53 Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe
