(*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.
Werner Lemberg efe7f648 2018-09-25T09:16:45 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 0f122fef 2018-09-23T21:46:26 [bdf] Speed up charmap access. This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster. * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search with continuous prediction.
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 c168cc3b 2018-09-21T11:09:27 [raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers.
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.
Alexei Podtelezhnikov c1b21f47 2018-09-20T22:14:46 [pcf] Replace charmap implementation. PCF comes with charmap lookup table, aka PCF encodings. Using it directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster than the original BDF-like binary searches. * src/pcf/pcf.h (PCF_EncodingRec): Removed. (PCF_FaceRec): Remove `nencodings' and `encodings'. * src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced. * src/pcf/pcfread.c (pcf_get_encodings): Store data differently.
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.
Alexei Podtelezhnikov 7f93c977 2018-09-19T22:45:45 [pcf] Prepare to replace charmap implementation. * src/pcf/pcf.h (PCF_Face): Updated to include... (PCF_EncRec): ... this new structure to store charmap geometry. * src/pcf/pcfread.c (pcf_get_encodings): Store charmap geometry.
Alexei Podtelezhnikov d629c2ba 2018-09-18T17:11:48 Remove unused fields. * src/pcf.h (PCF_FaceRec): Remove `charmap' and `charmap_handle'. * src/bdfdrvr.h (BDF_FaceRec): Ditto. * src/winfonts/winfnt.h (FNT_FaceRec): Ditto.

(tt_face_vary_cvt): Protect against missing `tuplecoords' array. Fix typo.

John Tytgat 6b53300b 2018-09-12T08:08:09 [sfnt] Better PS name handling (#54629). * src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks. (get_win_string, get_apple_string): Return NULL when the PostScript font name characters is not according to specification. (get_win_string): Make trace output work if the high byte if non-zero. (sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred Win PS name (when there is also an Apple PS name); change this into a fallback to Apple PS name in case the Win PS name is invalid.

Werner Lemberg 6e339b8d 2018-08-26T11:59:02 [truetype] Avoid nested frames. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054 * src/truetype/ttgload.c (load_truetype_glyph): Don't use variable `opened_frame' to trace whether a frame must be closed at the end of function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which gets called for space glyphs) uses a frame by itself. Instead, close the frame after loading the header, then use another frame for the remaining part of the glyph later on. Also avoid calling `tt_get_metrics' twice under some circumstances.
Werner Lemberg b287c80b 2018-08-26T06:39:43 Various minor clean-ups. * src/base/ftapi.c: Remove. Unused. * src/base/Jamfile (_sources): Updated. * src/base/ftstream.c (FT_Stream_ReleaseFrame): Remove redundant code.

Alexei Podtelezhnikov 923fcbcd 2018-08-15T22:50:06 [bdf] Don't track duplicate encodings. There is no harm except some umbiguity in broken fonts with duplicate encodings. * src/bdf/bdflib.c (_bdf_parse_glyphs): Remove duplicate tracking. (_bdf_parse_t): Remove large `have' bitfield.
Werner Lemberg a0dd16fb 2018-08-15T18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.

Alexei Podtelezhnikov 88c0e121 2018-08-10T21:24:40 * src/sfnt/ttsbit.c (tt_sbit_decoder_load_compound): Follow specs.
Ben Wagner 96b5e500 2018-08-10T22:24:26 * src/sfnt/sfobjs.c (sfnt_done_face): Fix memory leak (#54435).
Werner Lemberg 1aa73fa8 2018-08-10T05:41:32 * src/base/ftobjs.c (FT_Render_Glyph_Internal): Improve tracing.
Werner Lemberg c8ef0fd0 2018-08-10T04:44:22 Fix clang warnings. * src/base/ftdebug.c (ft_trace_level_enabled, ft_trace_level_disabled): Add `static' keyword.
Alexei Podtelezhnikov e16bfbec 2018-08-09T22:18:00 [raster, smooth] Reinstate bitmap size limits. This again moves outline and bitmap size checks one level up. * src/base/ftoutln.c (FT_Outline_Render): Explicitly reject enormous outlines. * src/raster/ftrend1.c (ft_raster1_render): Reject enormous bitmaps and, therefore, outlines that require them. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto. * src/raster/ftraster.c (ft_black_render): Remove outline size checks. * src/smooth/ftgrays.c (gray_raster_render): Ditto.

Alexei Podtelezhnikov 6a97c958 2018-08-08T22:17:35 [pcf] Revert massive unsigning.
Werner Lemberg f60c98fe 2018-08-08T18:15:53 [smooth] Improve tracing. * src/smooth/ftgrays.c (gray_convert_glyph_inner): Only use tracing if called the first time. (gray_convert_glyph): Updated.
Werner Lemberg c9bbc241 2018-08-08T18:12:31 Add internal functions `FT_Trace_Disable' and `FT_Trace_Enable'. It sometimes makes sense to suppress tracing informations, for example, if it outputs identical messages again and again. * include/freetype/internal/ftdebug.h: Make `ft_trace_levels' a pointer. (FT_Trace_Disable, FT_Trace_Enable): New declarations. * src/base/ftdebug.c (ft_trace_levels): Rename to... (ft_trace_levels_enabled): ... this. (ft_trace_levels_disabled): New array. (ft_trace_levels): New pointer. (FT_Trace_Disable, FT_Trace_Enable): Implement. (ft_debug_init): Updated.
Werner Lemberg 2e3dec55 2018-08-08T13:51:18 Debugging improvements. * src/base/ftobjs.c (pixel_modes): Move this array to top level from ... (FT_Load_Glyph): ... here. (FT_Render_Glyph_Internal): Use `width' x `height' in trace message. Use `pixel_modes'.
Alexei Podtelezhnikov c633378a 2018-08-08T01:21:54 [pcf] Massive unsigning (part 2). Treat all size related properties as unsigned values. * src/pcf/pcf.h (PCF_ParsePropertyRec): Use unsigned `name' and `value'. * src/pcf/pcfread.c (pcf_get_propeerties, pcf_load_font): Updated parsing code and handling of AVERAGE_WIDTH, POINT_SIZE, PIXEL_SIZE, RESOLUTION_X and RESOLUTION_Y.
Alexei Podtelezhnikov 3d4ab6ba 2018-08-08T00:09:16 [pcf] Massive unsigning (part 1). Unofficial specifications hesitate to use unsigned 32-bit integers. Negative values caused a lot of trouble in the past and it is safer and easier to treat some properties as unsigned. * src/pcf/pcf.h (PCF_AccelRec): Use unsigned values for `fontAscent', `fontDescent', and `maxOverlap'. * src/pcf/pcfread.c (pcf_load_font, pcf_get_accel): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load, PCF_Size_Select, PCF_Size_Request): Updated.
Alexei Podtelezhnikov 705bac50 2018-08-07T22:49:55 * src/pcf/pcfread.c (pcf_get_bitmaps): Unsign `offsets' and `bitmapSizes'.
