| |
| [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. |

| |
| [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 strokes for non-default instances. |

| * 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. |

| 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. |

| * 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. |

| [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. |

| |
| 2016-09-11 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. |

| `sbit_strike_map' array pointer. |

| |
| [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. |
| |
| 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> |

| |
| * include/freetype/internal/tttypes.h (TT_FaceRec) |
| [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and |

| |
| This removes unnecessary complexity of span merging and buffering. |
| Instead, the spans are rendered as they come, speeding up the |

| |
| * src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed. |
| (gray_TWorker): Remove span buffer and related fields. |
| (gray_sweep, gray_hline): Updated. |

| [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 |

| fonts on Fedora and did not see any change. |

| [truetype] Add support for Apple's |

| |
| [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. |

| |
| [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'. |

| |
| * 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. |

| |
| [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. |

| [sfnt] Fix `face_index' value in `FT_Face' for named instances. |

| |
| 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. |
