Werner Lemberg 6b354931 2016-10-08T20:26:59 * src/cid/cidload.c (cid_face_open): Properly propagate `error'.
Werner Lemberg d61b0425 2016-10-08T19:20:33 [cid] Fix parsing of subr offsets. Bug introduced 2016-05-16. * src/cid/cidparse.c (cid_parser_new): Fix off-by-one error.
Werner Lemberg fcc0ee80 2016-10-01T20:12:25 [sfnt] Disable bitmap strikes if we don't have a bitmap data table. * src/sfnt/ttsbit.c (tt_face_load_sbit): Check whether we have a bitmap data table.
Alexei Podtelezhnikov b0aacff4 2016-10-01T12:55:33 [smooth] Remove impossibility. * src/smooth/ftgrays.c (TWorker): Rearrange fields. (gray_convert_glyph): Remove impossible condition and clean up.
Werner Lemberg 3576487a 2016-09-30T08:11:52 [pcf] Enrich family name with foundry name and glyph width info. This is a very old patch from openSuSE (from 2006, submitted to FreeType in 2011) that I forgot to apply. https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch Prepend the foundry name plus a space to the family name. There are many fonts just called `Fixed' which look completely different, and which have nothing to do with each other. When selecting `Fixed' in KDE or Gnome one gets results that appear rather random, the style changes often if one changes the size and one cannot select some fonts at all. We also check whether we have `wide' characters; all put together, we get family names like `Sony Fixed' or `Misc Fixed Wide'. * src/pcf/pcfread.c (pcf_load_font): Implement it. * docs/CHANGES: Document it.
Werner Lemberg 71b617d8 2016-09-29T19:53:39 [ftfuzzer] Speed up. * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Don't check for embedded bitmaps if we have a non-default instance.
Werner Lemberg bfa83bdc 2016-09-29T19:51:28 Comments.
Werner Lemberg 2067c698 2016-09-29T19:49:07 [truetype] Disallow bitmap strokes for non-default instances. Also speed up access of default instances if GX variations are active. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `is_default_instance' member. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `is_default_instance'. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Add test for default instance. (TT_Load_Glyph): Load embedded bitmaps for default instance only. * src/truetype/ttgxvar.c (TT_Set_MM_Blend): Compute `is_default_instance'.
Werner Lemberg bf90239c 2016-09-29T13:04:46 [truetype] Clean up `TT_Face' structure. * include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused fields `horz_metrics' and `vert_metrics'. Update documentation. * src/sfnt/sfobjs.c (sfnt_done_face): Updated.
Werner Lemberg 45cad2e5 2016-09-28T19:10:52 More FT_ZERO usage. * src/gxvalid/gxvcommn.c (gxv_ClassTable_validate): s/ft_memset/FT_MEM_ZERO/. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): s/ft_memset/FT_ARRAY_ZERO/. * src/raster/ftraster.c (FT_ZERO): Define. (ft_black_new): Use it. * src/raster/ftrend1.c (ft_raster1_get_cbox): s/FT_MEM_ZERO/FT_ZERO/. * src/smooth/ftgrays.c (FT_ZERO): Define. (gray_raster_new): Use it. * src/smooth/ftsmooth.c (ft_smooth_get_cbox): s/FT_MEM_ZERO/FT_ZERO/.
Werner Lemberg 2ecf89b4 2016-09-28T19:06:21 */*: s/FT_MEM_ZERO/FT_ZERO/ where appropriate.
Werner Lemberg a3e2c832 2016-09-27T21:42:02 [truetype] Trace number of executed opcodes. * src/truetype/ttinterp.c (TT_RunIns): Implement it.
Werner Lemberg e27b8a55 2016-09-27T21:21:01 [truetype] Speed up `TT_Load_Glyph'. This avoids additional calls to `tt_face_lookup_table' for the `glyf' table, which can be expensive. * include/freetype/internal/tttypes.h (TT_LoaderRec): Move `glyf_offset' field to ... (TT_FaceRec): ... this structure. * src/truetype/ttgload.c (load_truetype_glyph): Updated. (tt_loader_init): Move initialization of `glyf_offset' to ... * src/truetype/ttpload.c (tt_face_load_loca): .. this function.
Werner Lemberg 0d945929 2016-09-27T08:44:31 [truetype] Introduce dynamic limits for some bytecode opcodes. This speeds up FreeType's handling of malformed fonts. * src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number of twilight points, the total number of negative jumps, and the total number of loops in LOOPCALL opcodes. The values are based on the number of points and entries in the CVT table. (Ins_JMPR): Test negative jump counter. (Ins_LOOPCALL): Test loopcall counter. * src/truetype/ttinterp.h (TT_ExecContext): Updated. * docs/CHANGES: Updated.
Werner Lemberg a764963f 2016-09-25T16:29:05 [truetype] Sanitize only last entry of `loca' table. Without this patch, a loca sequence like `0 100000 0 100000 ...', where value 100000 is larger than the `glyf' table size, makes FreeType handle the whole `glyf' table as a single glyph again and again, which is certainly invalid (and can be very slow, too). * src/truetype/ttpload.c (tt_face_get_location): Implement. Improve tracing messages.
Werner Lemberg d11e8b6e 2016-09-25T15:32:04 * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Fix typo.
Werner Lemberg 2f2e73c5 2016-09-24T22:42:58 [autofit] Tracing fixes. * src/autofit/afmodule.c (af_autofitter_load_glyph): Call dumping functions only if we actually do tracing.
Alexei Podtelezhnikov 53ae7a54 2016-09-22T22:48:15 [smooth] Reduce divisions in the line renderer. We don't need some divisions if a line segments stays within a single row or a single column of pixels. * src/smooth/ftgrays.c (gray_render_line) [FT_LONG64]: Make divisions conditional.
Werner Lemberg c95b7652 2016-09-17T17:12:50 s/0/NULL/ for function pointers; comments, formatting.
Alexei Podtelezhnikov d5f7533e 2016-09-15T00:13:36 * src/smooth/ftgrays.c (gray_sweep): Remove check for empty table.
Alexei Podtelezhnikov ad47550b 2016-09-14T23:15:03 [smooth] Another tiny speed-up. * src/smooth/ftgrays.c (gray_find_cell): Merge into... (gray_record_cell): ... this function.
Alexei Podtelezhnikov c38be52b 2016-09-11T22:44:44 * src/smooth/ftgrays.c (gray_{find,set}_cell): Remove dubious code.
Alexei Podtelezhnikov 6ca54c64 2016-09-11T16:00:52 [smooth] Fix valgrind warning and reoptimize. The algorithm calls `gray_set_cell' at the start of each new contour or when the contours cross the cell boundaries. Double-checking for that is wasteful. * src/smooth/ftgrays.c (gray_set_cell): Remove check for a new cell. (gray_convert_glyph): Remove initialization introduced by 44b172e88.
Werner Lemberg e421a0bf 2016-09-10T08:02:30 [sfnt] Fix previous commit. Problems reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40 We now map the strike index right before accessing the physical data, not earlier. * src/sfnt/sfobjs.c (sfnt_load_face): Set `face->sbit_strike_map' after creating the map so that... * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): ... this function can be used before and after setting up `sbit_strike_map'. (tt_face_set_sbit_strike): Revert change. (tt_sbit_decoder_init, tt_face_load_sbix_image): Map strike index. * src/truetype/ttdriver.c (tt_size_select): Revert change.
Werner Lemberg deb26155 2016-09-09T22:13:33 [ftfuzzer] Minor improvements. * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Ignore invalid strikes. Use better values for call to `FT_Set_Char_Size'.
Werner Lemberg d609b7c1 2016-09-09T22:11:07 [sfnt] Don't provide (completely) broken strike data. FreeType tries to sanitize strike header data; we now reject completely broken ones. * include/freetype/internal/tttypes.h (TT_FaceRec): New `sbit_strike_map' array pointer. * src/base/ftobjs.c (FT_Match_Size): Reject matches where either width or height would be zero. Add tracing message in case of error. * src/sfnt/sfobjs.c (sfnt_load_face): Populate `sbit_strike_map', only using (more or less) valid strike header data for FT_Face's `available_sizes' array. (sfnt_done_face): Updated. * src/sfnt/ttsbit.c (tt_face_set_sbit_strike): Use `sbit_strike_map'. (tt_face_load_strike_metrics): Improve tracing. * src/truetype/ttdriver.c (tt_size_select): Use `sbit_strike_map'.
Werner Lemberg b1e7b68e 2016-09-08T08:56:34 * src/truetype/ttinterp.c: Include `ttgxvar.h'. This fixes the `multi' build.
Werner Lemberg 9749f269 2016-09-08T07:51:03 [autofit] Another improvement to Armenian support. Suggested by Hrant H Papazian <hpapazian@gmail.com>. * src/autofit/afscript.h: Use better suited characters to derive default stem widths.
Alexei Podtelezhnikov a0b92bcb 2016-09-07T23:19:57 * src/smooth/ftgrays.c (gray_hline): Microptimize.
Alexei Podtelezhnikov 9d0a3bd8 2016-09-06T23:59:33 [smooth] Operate in absolute bitmap coordinates. Simpler bitmap addressing improves performance by 1.5%. * src/smooth/ftgrays.c (gray_TWorker): Remove count fields. (gray_dump_cells, gray_find_cell, gray_set_cell, gray_hline, gray_sweep, gray_convert_glyph, gray_raster_render): Updated.
Alexei Podtelezhnikov 44b172e8 2016-09-06T23:24:17 [smooth] Improve contour start (take 2). * src/smooth/ftgrays.c (gray_move_to): Call `gray_set_cell' directly instead of... (gray_start_cell): ... this function, which is removed. (gray_convert_glyph): Make initial y-coordinate invalid.
Werner Lemberg ebbb8b2e 2016-09-06T16:28:57 [type1] MM fonts support exactly zero named instances (#48748). * src/type1/t1load.c (T1_Get_MM_Var): Set `num_namedstyles' to zero.
Jonathan Kew a15133e6 2016-09-06T06:33:36 [cff] Fix uninitialized memory. Problem reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1270288 * src/cff/cf2interp.c (cf2_interpT2CharString): Initialize `storage' array to handle a `get' opcode without a previous `put'.
Alexei Podtelezhnikov 9773d5f7 2016-09-05T23:33:35 * src/smooth/ftgrays.c (gray_move_to, gray_start_cell): Revert.
Alexei Podtelezhnikov 7effc279 2016-09-05T21:58:56 [smooth] Improve contour start. * src/smooth/ftgrays.c (gray_move_to): Call `gray_set_cell' directly instead of... (gray_start_cell): ... this function, which is removed.
Werner Lemberg 3ebfe3c5 2016-09-05T10:55:07 [cff] Fix memory initialization. * src/cff/cf2stack.c (cf2_stack_init): Use `FT_NEW'. The `Q' variants of FreeType's memory allocation macros don't do zeroing.
Werner Lemberg 1c8bb632 2016-09-05T08:13:42 [ftrandom] Minor improvements. * src/tools/ftrandom/ftrandom.c (_XOPEN_SOURCE): New macro, set to 500. * src/tools/ftrandom/Makefile (CFLAGS): Split off include directories to ... (INCLUDES): ... this new variable. (LDFLAGS): New variable. (ftrandom.o, ftrandom): Updated.

Werner Lemberg 4b28f6ac 2016-09-04T19:05:45 [ftrandom] Improve Makefile. It now supports both a normal build (`./configure && make') and a development build (`make devel'). * src/tools/ftrandom/Makefile (VPATH): Set it so that `libfreetype.a' gets searched in both `objs' (for the development build) and `objs/.libs' (for a normal build which uses libtool). (LIBS): Add missing libraries. (ftrandom.o): New rule. (ftrandom): Use automatic variables.
Werner Lemberg 4e659d7e 2016-09-03T18:14:00 [truetype] More fixes for handling of GX deltas. Problems reported by Bob Taylor <Bob.Taylor@monotype.com>. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix rough sanity test for glyph variation array header size. Always set stream position before reading packed x and y deltas. Fix thinko w.r.t. `localpoints' array.
Werner Lemberg ca8e98d9 2016-09-03T13:06:16 [ftrandom] Various fixes. * src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better default. (error_fraction): Make it of type `double' to work as advertized – this was completely broken. Update all related code. (error_count, fcnt): Make it unsigned to fix compiler warnings. Update all related code. (fontlist): Change `len' member to `long' to fix compiler warnings. (FT_MoveTo, FT_LineTo, FT_ConicTo, FT_CubicTo, abort_test): Tag unused variables. (TestFace, FindFonts, copyfont, do_test): Fix compiler warnings. (ExecuteTest): Ditto. Call `FT_Done_FreeType'. (getErrorCnt): Replace `ceil' with an ordinary cast to `unsigned int'. (usage): Improve output. (main): Fix compiler warnings. * src/tools/ftrandom/README: Updated.
Werner Lemberg b98dfda3 2016-09-03T08:20:31 [base] Avoid negative bitmap stroke dimensions (#48985). * src/base/ftobjs.c (FT_Open_Face): Check whether negation was actually successful. For example, this can fail for value -32768 if the type is `signed short'. If there are problems, disable the stroke.
Werner Lemberg f0fa7a67 2016-09-03T06:33:36 [cff] Avoid null pointer passed to FT_MEM_COPY (#48984). * src/cff/cffload.c (cff_index_get_name): Check `byte_len'.
Werner Lemberg d8ef7266 2016-09-02T23:27:50 [sfnt] Avoid left shift of negative value (#48980). * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bit_aligned): Use unsigned constant.
Werner Lemberg 16583ccd 2016-09-02T22:45:14 * src/smooth/ftgrays.c (gray_hline): Fix clang compiler warnings.
Alexei Podtelezhnikov 11d3336a 2016-09-01T22:56:24 [smooth] Simplify span rendering more. It turns out that there is significant cost associated with `FT_Span' creation and calls to `gray_render_span' because it happerns so frequently. This removes these steps from our internal use but leaves it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain is about 5%. * src/smooth/ftgrays.c (gray_render_span): Removed. The code is migrated to... (gray_hline): ... here.
Alexei Podtelezhnikov f44ddfda 2016-08-30T23:21:23 [smooth] Streamline pixmap drawing a bit more. Zero coverage is unlikely (1 out of 256) to warrant checking. This gives 0.5% speed improvement in dendering simple glyphs. * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
Alexei Podtelezhnikov e73055c7 2016-08-29T23:15:35 [smooth] Streamline pixmap drawing. This gives 2% speed improvement in rendering simple glyphs. * src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a pointer to its bottom-left and pitch to be used in... (gray_TWorker): ... here. (gray_render_span): Move pixmap flow check from here... (gray_raster_render): .. to here.
Werner Lemberg bffe5fd6 2016-08-28T13:16:37 [cff] Minor comment.
Alexei Podtelezhnikov 4d3f7ca8 2016-08-27T23:25:54 [smooth] Reduce stack of band boundaries. * src/smooth/ftgrays.c (gray_TBand): Removed. (gray_convert_glyph): Updated to stack band boundaries concisely.
Werner Lemberg 57aa8391 2016-08-26T11:59:50 * src/cid/cidload.c (cid_face_open): Improve handling of `SDBytes'.
Werner Lemberg 3c61a2f5 2016-08-26T11:50:09 [cid] Fix commit from 2016-05-16. * src/cid/cidparse.c (cid_parser_new): Fix off-by-one errors.
Werner Lemberg f3e71bab 2016-08-26T10:31:30 [sfnt] Cache offset and size to bitmap data table. This commit avoids `EBDT' and friends being looked up again and again while loading a single embedded bitmap. * include/freetype/internal/tttypes.h (TT_FaceRec) [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and `ebdt_size'. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Move table lookup to ... (tt_face_load_sbit): ... this function; also store the table size and offset.
Werner Lemberg 1034ff4a 2016-08-26T08:42:27 [sfnt] Comments.

Werner Lemberg 69ce9739 2016-08-25T19:49:52 [sfnt] Fix previous commit (#48901). * src/sfnt/ttcmap.c (tt_cmap4_char_map_binary): Thinkos.
Werner Lemberg acd18798 2016-08-25T17:12:46 [sfnt] Speed up handling of invalid format 4 cmaps. * src/sfnt/ttcmap.c (tt_cmap4_next, tt_cmap4_char_map_binary): Add tests for `num_glyph' from `tt_cmap4_char_map_linear'.
Alexei Podtelezhnikov cb438878 2016-08-22T23:06:45 [smooth] Simplify span rendering. This removes unnecessary complexity of span merging and buffering. Instead, the spans are rendered as they come, speeding up the rendering by about 5% percents as a result. * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed. (gray_TWorker): Remove span buffer and related fields. (gray_sweep, gray_hline): Updated. * include/freetype/ftimage.h: Remove documentation note about `FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone.
Werner Lemberg a4c2a311 2016-08-22T19:32:34 [truetype] Fix `MPS' instruction. According to Greg Hitchcock, MPS in DWrite really returns the point size. * src/truetype/ttobjs.h (TT_SizeRec): Add `point_size' member. * src/truetype/ttdriver.c (tt_size_request): Set `point_size'. * src/truetype/ttinterp.h (TT_ExecContextRec): Add `pointSize' member. * src/truetype/ttinterp.c (TT_Load_Context): Updated. (Ins_MPS): Fix instruction.
Werner Lemberg 8521ad99 2016-08-16T13:44:38 [lzw] Optimize last commit. * src/lzw/ftzopen.c (ft_lzwstate_get_code): Move check into conditional clause.
Werner Lemberg 548f68d8 2016-08-16T09:46:40 [lzw] Avoid invalid left shift. * src/lzw/ftzopen.c (ft_lzwstate_get_code): Limit `num_bits'.
Werner Lemberg 8d7b9198 2016-08-16T08:07:58 [lzw] Avoid buffer overrun. Reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1273283 * src/lzw/ftzopen.c (ft_lzwstate_refill): Ensure `buf_size' doesn't underflow.
Werner Lemberg cf4224ad 2016-08-16T06:44:23 [truetype] Fix compiler warning. * src/truetype/ttgload.c (load_truetype_glyph): Add cast.
Werner Lemberg 248f5629 2016-08-13T06:53:53 [winfonts] Avoid zero bitmap width and height. Reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1272173 * src/winfonts/winfnt.c (FNT_Face_Init): Check zero pixel height. (FNT_Load_Glyph): Check for zero pitch.
Alexei Podtelezhnikov 125f2b63 2016-08-11T23:40:05 * src/truetype/ttinterp.c (Pop_Push_Count): Revert changes.
Alexei Podtelezhnikov 49d474f6 2016-08-11T23:03:09 * src/truetype/ttinterp.c (TT_RunIns): Minor and formatting.

Werner Lemberg 5224aae8 2016-08-10T19:47:29 [sfnt] Use correct type for `italicAngle' field (#48732). * src/sfnt/ttload.c (tt_face_load_post): Fix types.
Werner Lemberg 53059f92 2016-08-07T09:01:33 [sfnt] Fix `FT_Get_Advance' for bitmap strikes. `FT_Get_Advance' returns 0 for bitmap fonts. It first gets the advance value from the font table and then scales it by the `font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't set that value for bitmap fonts and the advance gets scaled to zero. Taken from https://github.com/behdad/harfbuzz/issues/252 * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_EBLC>: Set scale values.
Behdad Esfahbod 8183eeb1 2016-08-06T23:12:55 [truetype] Fix GX variation handling of composites. * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag.
Alexei Podtelezhnikov 97718f3c 2016-08-05T23:36:16 [smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line): Updated.
Werner Lemberg 053943a7 2016-07-30T00:27:48 [truetype] Comment.
Werner Lemberg fae4ec05 2016-07-29T06:43:32 [sfnt, truetype] Don't abort on invalid `maxComponentDepth'. Since 2016-05-16 we detect infinite recursion directly. * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust `maxComponentDepth'. * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if `maxComponentDepth' is not valid. Instead, simply adjust its value and emit a tracing message.
Werner Lemberg d9c7f5aa 2016-07-26T20:20:27 * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor. No functional change.
Hin-Tak Leung 3a528bbe 2016-07-22T06:59:36 [truetype] Record the end of IDEFs. To match the logic in FDEF. The value of the end is only used for bound-checking in `Ins_JMPR', so it may not have been obvious that it was not recorded. Tested (as part of Font Validator 2.0) all the fonts on Fedora and did not see any change. * src/truetype/ttinterp.c (Ins_IDEF): Updated.
Werner Lemberg 7f63105c 2016-07-19T21:35:58 [truetype] Sanitizer fix, second try. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests and use only one slot more.
Werner Lemberg 9f6426eb 2016-07-19T07:23:17 Thinko; fix previous commit.
Werner Lemberg e69f34b1 2016-07-19T07:06:19 [truetype] Sanitizer fix. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array to fix nested loops.
Werner Lemberg a3b70d76 2016-07-18T06:23:36 [truetype] Make GETDATA work only for GX fonts. * src/truetype/ttinterp.c (opcode_name): Updated. (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'. (TT_RunIns): Updated.
Werner Lemberg 8c93013c 2016-07-17T22:40:31 [truetype] Add support for Apple's GETDATA[], opcode 0x92 bytecode instruction. It always returns 17, and we have absolutely no idea what it is good for... * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated. (Ins_GETDATA): New function. (TT_RunIns): Add it.
Werner Lemberg e0843609 2016-07-16T18:46:28 [truetype] Add bytecode support for GX variation fonts. This commit implements undocumented (but confirmed) stuff from Apple's old bytecode engine. GETVARIATION[], opcode 0x91 This opcode pushes normalized variation coordinates for all axes onto the stack (in 2.14 format). Coordinate of first axis gets pushed first. GETINFO[], selector bit 3 If GX variation support is enabled, bit 10 of the result is set to 1. * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H. (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated. (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector bit 3, checking support for variation glyph hinting. (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to implement opcode 0x91. (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
Werner Lemberg 32a32062 2016-07-16T16:39:26 [truetype] Fix GETINFO bytecode instruction. * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for stretching information.
Behdad Esfahbod 69446ddc 2016-07-16T10:52:38 [truetype] Make all glyphs in `Zycon' GX font work. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests.
Werner Lemberg a3b61253 2016-07-16T08:16:16 [truetype] Fix GX delta tracing. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace relative point movements.
Werner Lemberg f147fb28 2016-07-16T07:06:21 [truetype] More fixes for GX. This finally fixes the rendering of the cyclist and the lizard in the `Zycon' font. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point index is always cumulative. (tt_handle_deltas): Rename to... (tt_interpolate_deltas): ... This. Add new parameter for output point array. Update caller. (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds the intermediate results of `tt_interpolate_deltas' that are to be added to `outline->points'.
Werner Lemberg aafff574 2016-07-16T06:41:39 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko. `max_pos' is always larger than `min_pos' so `FT_ABS' is not needed. Reported by Alexei.
Nikolaus Waxweiler 86eb43a9 2016-07-16T06:37:57 * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. Problem reported by Hin-Tak Leung.
Werner Lemberg 1831e6f0 2016-07-15T10:35:32 [autofit] Update and improve segment and edge tracing. * src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace `delta' also. Don't show first point of segment as a replacement for `pos'; this is (a) misleading, since the difference to `pos' can be almost arbitrarily large in corner cases, and (b) it is better to have all segment data in font units instead of a single value given in output space coordinates. Improve layout. (af_glyph_hints_dump_edges): Show px->units and units->px conversion values for convenience. Improve layout.
Werner Lemberg 894c0228 2016-07-15T10:23:11 [autofit] For edges, reject segments wider than 1px (#41334). * src/autofit/afhints.h (AF_SegmentRec): New member `delta'. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute `delta'. (af_latin_hints_compute_edges): Reject segments with a delta larger than 0.5px.
Werner Lemberg ee3f36f6 2016-07-14T10:25:20 [sfnt] Fix `face_index' value in `FT_Face' for named instances. * src/sfnt/sfobjc.s (sfnt_init_face): Don't strip off higher 16bits.
Werner Lemberg 631e2181 2016-07-14T06:25:05 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
Behdad Esfahbod 0f9ddf20 2016-07-14T06:08:39 [truetype] Fix gxvar delta interpolation. The coordinates of the base font should be used for interpolation purposes, NOT the current points (i.e., the result of accumulation of previous deltas). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize `points_org' before looping over all tuples.
Werner Lemberg 605946af 2016-07-11T16:14:36 Conditionally compile environment support. * include/freetype/internal/ftobjs.h, src/autofit/afmodule.c, src/base/ftobjs.c, src/cff/cffdrivr.c, src/truetype/ttdriver.c: Decorate with `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' where necessary.
Werner Lemberg 8f8ae8c5 2016-07-11T15:11:38 Handle properties in `FREETYPE_PROPERTIES' environment variable. This commit covers the most important one. * src/autofit/afmodule.c (af_property_set): Handle `warping', `darkening-parameters', and `no-stem-darkening'. * src/cff/cffdrivr.c (cff_property_set): Handle `darkening-parameters', `hinting-engine', and `no-stem-darkening'. * src/truetype/ttdriver.c (tt_property_set): Handle `interpreter-version'.
Werner Lemberg c3e83b46 2016-07-11T05:56:26 Replace calls to `atol' with `strtol'. We later on need strtol's `endptr' feature. * include/freetype/config/ftstdlib.h (ft_atol): Replace with... (ft_strtol): ... this. * src/base/ftdbgmem.c (ft_mem_debug_init): Updated. * src/cid/cidparse.c (cid_parser_new): Ditto. * src/type42/t42drivr.c (t42_get_name_index), src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto.
Werner Lemberg 84d3df75 2016-07-11T00:12:11 Implement handling of `FREETYPE_PROPERTIES' environment variable. Recognizing properties follows in another commit. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES): New macro. * include/freetype/config/ftstdlib.h (ft_getenv): New macro. * src/base/ftinit.c (ft_set_default_properties): New function to parse `FREETYPE_PROPERTIES' and calling `ft_property_string_set'. (FT_Init_FreeType): Updated.
Werner Lemberg c3beb30a 2016-07-10T07:11:45 Add function `ft_property_string_set'. This is a preparation for handling an `FREETYPE_PROPERTIES' environment variable to control (some) driver properties. No change in functionality. * src/base/ftobjs.c (ft_property_do): Add `value_is_string' parameter. (ft_property_string_set): New function. (FT_Property_Set, FT_Property_Get): Updated. * include/freetype/internal/ftobjs.h: Updated. * include/freetype/internal/services/svprop.h (FT_Properties_SetFunc): Add `value_is_string' parameter. * src/autofit/afmodule.c (af_property_set), src/cff/cffdrivr.c (cff_property_set), src/truetype/ttdriver.c (tt_property_set): Updated, emitting an error currently if `value_is_string' is set.
