d8a83232	2016-11-06T12:33:18	Minor documentation improvement.
37e193e9	2016-11-06T12:32:51	Introduce a way of quickly retrieving (embedded) bitmap metrics. `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph until the user calls `FT_Render_Glyph'. However, it always allocates memory for bitmaps and copies or decodes the contents of a bitmap glyph, which can be quite slow for PNG data. * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if FT_LOAD_BITMAP_METRICS_ONLY is used. * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_bitmap): Add argument to control allocation of the glyph slot. (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound, tt_face_load_sbit_image): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if `FT_LOAD_BITMAP_METRICS_ONLY' is set. * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add argument to control allocation of the glyph slot. * src/pfr/pfrobjs (pfr_slot_load): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. * docs/CHANGES: Updated.
57f73d1f	2016-11-06T06:06:30	Synchronize with gnulib (#49448). * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in, builds/vms/ftconfig.h (FT_TYPEOF): Update code to use definition in current version of `intprops.h'. Other minor synchronization to reduce code differences between the three files.
b72858c9	2016-11-03T06:41:00	[truetype] Clamp variation requests to valid range. This is required by OpenType 1.8; it also avoids rounding surprises. * src/truetype/ttgxvar.c (TT_Set_Var_Design): Clamp design coordinates outside of the allowed range to always stay within the range instead of producing an error.
328d6844	2016-10-29T00:18:56	[truetype] Remove clang warnings. * src/truetype/ttinterp.h (TT_ExecContextRec): Using `FT_ULong' for loop counter handling. * src/truetype/ttinterp.c: Updated. (Ins_SCANTYPE): Use signed constant. (TT_RunIns): Ensure `num_twilight_points' is 16bit.

c5f1bc4b	2016-10-25T22:31:42	[cff] Correct cmap format reporting (#24819). * src/cff/cffdrivr.c (cff_get_cmap_info): Throw an error on synthetic charmap instead of guessing its format and language.
5081674c	2016-10-22T19:16:08	[truetype] Fix SCANTYPE instruction (#49394). * src/truetype/ttinterp.c (Ins_SCANTYPE): Only use lower 16bits.
57741403	2016-10-22T18:34:48	[sfnt] Improve handling of invalid post 2.5 tables [#49393]. * src/sfnt/ttpost.c (load_format_25): We need at least a single table entry.
7eeaf986	2016-10-14T08:58:17	[truetype] Fix handling of `cvar' table data. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=53 * src/truetype/ttgxvar.c (tt_face_vary_cvt): Ignore invalid CVT indices.

92281228	2016-10-11T07:12:12	* src/truetype/ttgxvar.c (tt_done_blend): Fix deallocation.
6b354931	2016-10-08T20:26:59	* src/cid/cidload.c (cid_face_open): Properly propagate `error'.
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.
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.
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.
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.
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.
bfa83bdc	2016-09-29T19:51:28	Comments.
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'.
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.
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/.
2ecf89b4	2016-09-28T19:06:21	/: s/FT_MEM_ZERO/FT_ZERO/ where appropriate.
a3e2c832	2016-09-27T21:42:02	[truetype] Trace number of executed opcodes. * src/truetype/ttinterp.c (TT_RunIns): Implement it.
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.
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.
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.
d11e8b6e	2016-09-25T15:32:04	* src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Fix typo.
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.
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.
c95b7652	2016-09-17T17:12:50	s/0/NULL/ for function pointers; comments, formatting.
d5f7533e	2016-09-15T00:13:36	* src/smooth/ftgrays.c (gray_sweep): Remove check for empty table.
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.
c38be52b	2016-09-11T22:44:44	* src/smooth/ftgrays.c (gray_{find,set}_cell): Remove dubious code.
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.
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.
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'.
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'.
d2d5968a	2016-09-08T09:04:32	* Version 2.7 released. ======================= Tag sources with `VER-2-7'. * docs/VERSION.TXT: Add entry for version 2.7. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.6.5/2.7/, s/265/27/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 7.

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.
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.
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.

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.
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.

(LIBS): Add missing libraries. (ftrandom.o): New rule. (ftrandom): Use automatic variables.
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.

(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.

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.
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.
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.
a6ee6fe6	2016-08-28T18:51:50	s/PIC/FT_CONFIG_OPTION_PIC/ to avoid confusion.
bffe5fd6	2016-08-28T13:16:37	[cff] Minor comment.

3ec64654	2016-08-28T11:02:00	Explain how to build a PIC-enabled version of FreeType.
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.
57aa8391	2016-08-26T11:59:50	* src/cid/cidload.c (cid_face_open): Improve handling of `SDBytes'.
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.
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 ...

Introduce a way of quickly retrieving (embedded) bitmap metrics. `FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph until the user calls `FT_Render_Glyph'. However, it always allocates memory for bitmaps and copies or decodes the contents of a bitmap glyph, which can be quite slow for PNG data. * include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New macro. * src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if FT_LOAD_BITMAP_METRICS_ONLY is used. * src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_bitmap): Add argument to control allocation of the glyph slot. (tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound, tt_face_load_sbit_image): Updated. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if `FT_LOAD_BITMAP_METRICS_ONLY' is set. * src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add argument to control allocation of the glyph slot. * src/pfr/pfrobjs (pfr_slot_load): Updated. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto. * docs/CHANGES: Updated.

[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.

[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.

[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.

[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.

[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.
