| |
| [ftfuzzer] Replace `rand' with an xorshift algorithm. |
| |
| * src/tools/ftfuzzer/ftfuzzer.cc: Don't include `stdlib.h'. |
| (Random): Implement and use a 32bit `xorshift' algorithm. |
| |
| 2016-12-30 Werner Lemberg <wl@gnu.org> |
| |
| [ftfuzzer] Restrict number of tested bitmap strikes. |
| |
| Malformed fonts often have large values for the number of bitmap |
| strikes, and FreeType doesn't check the validity of all bitmap |
| strikes in advance. |
| |
| Reported as |
| |
| https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353 |
| |
| * src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'. |
| (Random): Small class to provide n randomly selected numbers |
| (without repetition) out of the value set [1,N]. |
| (LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap |
| strikes. |
| |
| 2016-12-29 Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Variation font API stability issues. |
| |
| Make some functions work before a call to `TT_Set_MM_Blend'. |
| |
| * src/truetype/ttgxvar.c (tt_hadvance_adjust): Exit immediately if |
| we don't blend. |
| (TT_Get_MM_Blend, TT_Get_Var_Design): Return default values if we |
| don't blend. |
| |

| |
| 2016-12-28 Werner Lemberg <wl@gnu.org> |
| |
| [psnames] Only declare, not define, data in `pstables.h' (#49949). |
| |
| Pdfium includes `pstables.h' a second time; moving the definition |
| from `pstables.h' to `psmodule.c' saves more than 60kByte data |
| segment space for this case. |
| |
| * src/tools/glnames.py (StringTable::dump, |
| StringTable::dump_sublist, dump_encoding, dump_array): Emit |
| additional code to only define tables if `DEFINE_PS_TABLES' is set. |
| |
| * src/psnames/pstables.h: Regenerated. |
| * src/psnames/psmodule.c (DEFINE_PS_TABLES): Define. |

| Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Fix linear metrics of GX variation fonts (#49829). |
| |
| When asking for an unhinted non-default variations, |
| `linearVertAdvance' is currently the value from the `hmtx' table |
| instead of the actual value after applying the variation. `HVAR' |
| support fixes this, but fonts will exist without that table and will |
| need sane fallback. |

| |
| * src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar', |
| since glyph variation data is directly embedded. |
| (TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts. |

| [gzip] Improve building with external zlib (#49673). |
| |
| Building FreeType with external zlib 1.2.8 makes msvc 14 stop with |
| the following error. |
| |
| ftgzip.c |
| zlib-1.2.8\zlib.h(86): error C2061: |
| syntax error: identifier 'z_const' |
| zlib-1.2.8\zlib.h(94): error C2054: |
| expected '(' to follow 'z_const' |
| zlib-1.2.8\zlib.h(94): error C2085: |
| 'msg': not in formal parameter list |
| ... |
| zlib-1.2.8\zlib.h(877): fatal error C1003: |
| error count exceeds 100; stopping compilation |
| |
| The error happens because FreeType keeps an own copy of zlib-1.1.4 |
| under `src/gzip'. When building `src/gzip/ftgzip.c' with |
| FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses |
| |
| #include <zlib.h> |
| |
| which correctly finds an external `zlib.h', but `zlib.h' itself has |
| a line |
| |
| #include "zconf.h" |
| |
| which makes Visual Studio 2015 find `src/gzip/zconf.h' while |
| compiling the files in `src/gzip'. |
| |
| * src/gzip/zconf.h: Rename to... |
| * src/gzip/ftzconf.h: ... this. |
| * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated. |

| [sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format. |
| |
| It's unavoidable to call the PNG engine, but to get the metrics it |
| is sufficient to read the PNG image's header only. |
| |
| * src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the |
| allocation of the glyph slot. |
| * src/sfnt/pngshim.h: Updated. |
| * src/sfnt/ttsbit.c (tt_sbit_decoder_load_png, |
| tt_face_load_sbix_image, tt_face_load_sbit_image): Updated. |
| |

| |
| [sfnt] Speed up `sbix' lookup. |
| |
| This also fixes a bug introduced in 2016-10-01 which prevents |
| display of embedded bitmap fonts that use the `sbix' format. |
| |
| * src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and |
| offset also in `ebdt_size' and `ebdt_start', respectively. This |
| makes the test for an embedded bitmap data table succeed for this |
| format. |
| |
| (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use |
| `ebdt_size' and `ebdt_start' |

| |
| 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/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. |
| |
| 2016-09-29 Werner Lemberg <wl@gnu.org> |
| |
| [ftfuzzer] Speed up. |
| |
| * src/tools/ftfuzzer/ftfuzzer.cc (LLVMFuzzerTestOneInput): Don't |
| check for embedded bitmaps if we have a non-default instance. |
| |
| 2016-09-29 Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Disallow bitmap strikes 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 |

| [truetype] Trace number of executed opcodes. |
| |
| * src/truetype/ttinterp.c (TT_RunIns): Implement it. |
| |
| 2016-09-27 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2016-09-27 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2016-09-25 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2016-09-25 Werner Lemberg <wl@gnu.org> |

| functions only if we actually do tracing. |
| |
| 2016-09-22 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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. |
| |
| 2016-09-15 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| * src/smooth/ftgrays.c (gray_sweep): Remove check for empty table. |

| 2016-09-14 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [smooth] Another tiny speed-up. |
| |
| * src/smooth/ftgrays.c (gray_find_cell): Merge into... |

| |
| 2016-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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. |

| 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'. |

| |
| 2016-09-09 Werner Lemberg <wl@gnu.org> |
| |
| [sfnt] Don't provide (completely) broken strike data. |
| |
| FreeType tries to sanitize strike header data; we now reject |
| completely broken ones. |
| |

| `sbit_strike_map' array pointer. |
| |
| * src/base/ftobjs.c (FT_Match_Size): Reject matches where either |

| |
| [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 happens 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. |
| |
| 2016-08-30 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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 rendering simple glyphs. |
| |
| * src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks. |
| |
| 2016-08-29 Alexei Podtelezhnikov <apodtele@gmail.com> |

| [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% as a result. |

| |
| [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. |

| |
| [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. |

| |
| [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. |

| |
| [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. |
| |
| 2016-07-16 Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Fix GETINFO bytecode instruction. |

| [truetype] Make all glyphs in `Zycon' GX font work. |
| |

| 2016-07-16 Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Fix GX delta tracing. |
| |
| * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace |
| relative point movements. |
| |
| 2016-07-16 Behdad Esfahbod <behdad@behdad.org> |
| |
| [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'. |
| |
| 2016-07-15 Werner Lemberg <wl@gnu.org> |
| |
| * 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. |
| |
| 2016-07-16 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. |
| |
| Problem reported by Hin-Tak Leung. |
| |
| 2016-07-15 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2016-07-15 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2016-07-14 Werner Lemberg <wl@gnu.org> |
| |
| * include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro. |
| |
| 2016-07-14 Werner Lemberg <wl@gnu.org> |
| |
| [sfnt] Fix `face_index' value in `FT_Face' for named instances. |
| |
| * src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits. |
| |
| 2016-07-14 Werner Lemberg <wl@gnu.org> |
| |
| * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing. |
| |
| 2016-07-14 Behdad Esfahbod <behdad@behdad.org> |
| |
| [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. |
