4a2f8f1f | 2016-07-08 00:16:07 | [smooth] Sub-banding protocol revision. Rasterization sub-banding is utilized at large sizes while using rather small fixed memory pool. Indeed it is possible to make an educated guess how much memory is necessary at a given size for a given glyph. It turns out that, for large majority of European glyphs, you should store about 8 times more boundary pixels than their height. Or, vice versa, if your memory pool can hold 800 pixels the band height should be 100 and you should sub-band anything larger than that. Should you still run out of memory, FreeType bisects the band but you have wasted some time. This is what has been implemented in FreeType since the beginning. It was overlooked, however, that the top band could grow to twice the default band size leading to unnecessary memory overflows there. This commit fixes that. Now the bands are distributed more evenly and cannot exceed the default size. Now the magic number 8 is really suitable for rather simple European scripts. For complex Chinese logograms the magic number should be 13 but that is subject for another day. * src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding protocol. | |

5e353f07 | 2016-07-04 14:59:22 | [autofit] Handle single-point contours as segments. Doing so allows us to link them to edges – some fonts like `NotoSansGurmukhi-Regular' have such isolated points sitting exactly on other outlines. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't ignore one-point contours but handle them specially as one-point segments. (af_latin_hints_compute_edges): Append one-point segments to edges if possible. | |

|
8ba407a7 | 2016-06-25 18:09:22 | [truetype] Really fix deallocation in case of error (#47726). * src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize `outline.points' also. | |

Otherwise, treat SHPIX the same as DELTAP. Unbreaks various fonts such as older versions of Rokkitt and DTL Argo T Light that would glitch severly after calling ALIGNRP after a blocked SHPIX. | |
|
d28eac24 | 2016-05-30 00:23:59 | [type42] Support `CharStrings' entry format as created by LilyPond. * src/type42/t42parse.c (t42_parse_charstrings): Handle entries having the format (foo) cvn 12345 def | |
|
46d36904 | 2016-05-28 19:38:43 | * src/autofit/afranges.c: Remove `UL' postfix from hex numbers. Suggested by Alexei. `UL' is only needed for 16bit compilers, but it seems noone is using this anymore (and we no longer test whether FreeType compiles in such an environment). Otherwise, it is easy to add the postfix to the `AF_UNICODE_RANGE' macro. | |
|
e9f95093 | 2016-05-26 23:46:38 | [smooth] Shrink bisection stack. The convergence of Bézier flatteners is fast with the deviation from straight line being assymptotically cut 4-fold on each bisection. This justifies smaller bisection stack size. * src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'. (gray_render_conic): Create and use conic `bez_stack'. Move back the band analysis from... (gray_conic_to): ... here. (gray_render_cubic): Create and use cubic `bez_stack'. Move back the band analysis from... (gray_cubic_to): ... here. (gray_move_to): Updated. | |

a7d8bdbc | 2016-05-16 21:54:32 | [truetype] Improve the recursive reference detector. The previous fix for #46372 misunderstood a composite glyph referring same component twice as a recursive reference. See the discussion http://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html Thanks to Khaled Hosny for finding this issue. * src/truetype/ttgload.c (ft_list_get_node_at): A function to get the i-th node from FT_List.

7ae9b999 | 2016-05-07 16:24:03 | [cache] Allow value 0 for face ID. We never dereference `face_id', and some implementations might use a running number instead of a pointer. Additionally, disallowing value zero was undocumented. * src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c (FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for `face_id'. | |
|
6e88087d | 2016-05-05 23:41:03 | [smooth] More efficient accounting of conic splits and draws. A single decrement counter of segments to draw, instead of an array, contains all the information necessary to decide when to split and when to draw a conic segment. The number of splits before each draw is equal to the number of trailing zeros in the counter. * src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'. (gray_render_conic): Updated to use decrement counter of segments. | |
|
0b3cb8a8 | 2016-05-05 12:28:48 | [cff, truetype] Fix logic for `FT_Property_Set'. Otherwise some properties could be set to arbitrary values, which is harmless, but querying could give wrong positive results. * src/cff/cffdrivr.c (cff_property_set) [hinting-engine], * src/truetype/ttdriver.c (tt_property_set) [interpreter-version]: Only allow defined values. | |

c8c7ad79 | 2016-04-09 08:24:00 | [autofit] Add support for Georgian scripts. Georgian is problematic, since `uppercase' forms of Mkhedruli (called Mtavruli) are not yet defined in Unicode, which means that proper blue zones can't be defined. However, there is already a proposal submitted to Unicode; see http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf Additionally, due to historical reasons, Unicode treats Khutsuri as the same script as Mkhedruli, and so does OpenType. However, since the two scripts have completely different shapes it can happen that blue zones differ considerably. The tag `geok' used here (derived from ISO 15924) to differentiate the two scripts is not an OpenType tag in use. If we now have a font that contains both glyphs for Mkhedruli and Khutsuri, and it uses OpenType features for both also, HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence, blue zones for `geok' are not used for glyphs involved in the OpenType features. An issue not yet resolved is which OpenType feature should be used to access Mtavruli glyph shapes; right now, FreeType doesn't set up support for them, but it is easy to add them later on as soon as more information is available. * src/autofit/afblue.dat: Add blue zone data for Georgian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Georgian standard characters. * src/autofit/afranges.c: Add Georgian data. * src/autofit/afstyles.h: Add Georgian data. | |

ff82747e | 2016-03-29 09:19:22 | * src/base/ftadvance.c (FT_Get_Advances): Fix invalid left shift. | |
|
351fc4b4 | 2016-03-29 09:13:13 | [pfr] Fix binary search (#47514). * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Handle border conditions correctly. | |
|
2a03e5d9 | 2016-03-29 08:56:03 | [pfr] Minor. * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Replace `left', `right', and `middle' with `min', `max', and `mid' as used in other FreeType binary search code. (pfr_load_bitmap_metrics): Fix invalid left shift. | |
|
31dc8f98 | 2016-03-29 08:37:07 | * src/pfr/pfrtypes.h: Replace all enums with macros. We need `~FOO' to unset bits, and only with unsigned values (which `enum' isn't normally) this works cleanly. | |
|
f73a9937 | 2016-03-26 08:31:19 | [autofit] Mark `aflatin2.[ch]' as not compilable. | |

b069a590 | 2016-03-26 08:00:07 | [pfr] Robustify bitmap strike handling (#47514). We did a binary search for a charcode without ensuring that the searched data is ordered. Validating the order is now done lazily, this is, the first access to a bitmap glyph triggers the order check in the corresponding bitmap strike. * src/pfr/pfrtypes.h (PFR_BitmapFlags): New values `PFR_BITMAP_VALID_CHARCODES' and `PFR_BITMAP_CHARCODES_VALIDATED'. * src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Make `flags' argument a pointer. Handle new PFR_BITMAP_XXX flags. (pfr_slot_load_bitmap): Updated. | |
|
0003cb91 | 2016-03-26 07:34:30 | [pfr] Fix handling of compound glyphs. Extra items are indicated with different bit positions. * src/pfr/pfrtypes.h (PFR_GlyphFlags): Replace `PFR_GLYPH_EXTRA_ITEMS' with `PFR_GLYPH_SIMPLE_EXTRA_ITEMS' and `PFR_GLYPH_COMPOUND_EXTRA_ITEMS'. * src/pfr/pfrgload.c (pfr_glyph_load_simple, pfr_glyph_load_compound): Use them. | |
|
2aa69565 | 2016-03-25 10:54:37 | [pfr] Minor. * src/pfr/pfrsbit.c, srf/pfr/pfrobjs.c: Use flag names instead of bare numbers. | |
|
59828f72 | 2016-03-25 08:47:14 | [pfr] Various clang sanitizer fixes. * src/pfr/pfrsbit.c (pfr_load_bitmap_metrics): Correctly handle signed nibbles. (pfr_slot_load_bitmap): Correctly exit frame in case of error. Fix invalid left shifts. | |

31f2dc19 | 2016-03-23 07:31:59 | [raster, smooth] Directly test outline size (#47500). This improves stand-alone compilation. * src/base/ftoutln.c (FT_Outline_Render): Move cbox size test to... * src/raster/ftraster.c (ft_black_render), src/smooth/ftgrays.c (gray_raster_render): ...these functions. | |
|
e9181aba | 2016-03-23 06:58:20 | [raster, smooth] Fix some clang sanitizer runtime issues. * src/raster/ftraster.c (ft_black_reset, ft_black_set_mode, ft_black_render): Harmonize signatures with `ftimage.h'. * src/smooth/ftgrays.c (gray_raster_render, gray_raster_reset): Ditto. | |
|
b6633073 | 2016-03-22 08:26:55 | * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Minor. This fixes an AddressSanitizer issue: ttgload.c:430:7: runtime error: null pointer passed as argument 1, which is declared to never be null | |
|
614a8f17 | 2016-03-21 19:39:14 | * src/autofit/afhints.c (af_glyph_hints_reload): Thinko. This fixes the previous commit to this file. | |
|
3beccbdf | 2016-03-21 00:07:47 | [smooth] Partly revert recent changes. * src/smooth/ftgrays.c (gray_conic_to, gray_cubic_to): Rework conditions to fix rendering issues. | |
|
709486db | 2016-03-20 22:20:32 | [autofit] Show `near' points in tracing. * src/autofit/afhints.h (AF_FLAG_NEAR): New macro. * src/autofit/afhints.c (af_glyph_hints_dump_points): Implement it. (af_glyph_hints_reload): Handle AF_FLAG_NEAR. | |
|
8e8bb126 | 2016-03-18 23:21:59 | [smooth] Minor refactoring and microoptimizations. * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move band clipping from here. (gray_conic_to, gray_cubic_to): ... to here. (gray_rander_line, gray_render_scanline): Initialize variables closer to their use. | |
|
84b2c633 | 2016-03-17 00:53:09 | [smooth] Minor refactoring. * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move upscaling from here... (gray_conic_to, gray_cubic_to):... to here. | |

da86b73f | 2016-03-15 07:55:05 | * src/autofit/aflatin.c (af_latin_compute_stem_width): Optimize. | |
|
1865575a | 2016-03-14 22:39:22 | [smooth] Temporarily revert 6eb6158dd787 (#47114). * src/smooth/ftgrays.c (gray_render_line): Old implementation. | |
|
ee6b4115 | 2016-03-12 23:48:13 | [ftfuzzer] Improve coverage of rasterfuzzer. * src/tools/ftfuzzer/rasterfuzzer.cc (LLVMFuzzerTestOneInput): Use input data for `tags' array also. Trim input data to get more positive hits. | |
|
74c0a72d | 2016-03-09 20:35:27 | [truetype] Fix handling of non-intermediate GX tuples. We probably did not notice this as all fonts we tested had only tuple_coords[i] be +1 or -1 for non-intermediate tuples. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Implement it. | |
|
495de6cc | 2016-03-06 23:54:34 | [base] Refuse to render enormous outlines (#47114). The goal is to avoid integer overflows in the rendering algorithms. The limit is chosen arbitrarily at some 2^18 pixels, which should be enough for modern devices including printers. * src/base/ftoutln.c (FT_Outline_Render): Check CBox and reject enormous outlines. | |
|
d0b0e31e | 2016-03-06 23:01:50 | [smooth] Replace left shifts with multiplications (#47114). * src/smooth/ftgrays.c (SUBPIXELS, UPSCALE, DOWNSCALE): Do it. | |
|
caa48b0d | 2016-03-05 19:47:07 | [autofit] Avoid excessive stem length rounding (#25392). * src/autofit/aflatin.c (af_latin_compute_stem_width): Add argument to pass difference between hinted and unhinted position of base point; use this to adjust the stem width depending on the PPEM so that it doesn't become too large under certain circumstances. Update all callers using value 0 for this argument except... (af_latin_align_linked_edge): Pass position delta of base point to `af_latin_compute_stem_width'. | |
|
a8b95622 | 2016-03-01 09:37:12 | [ftfuzzer] Add unit for testing smooth and black rasterizers. * src/tools/ftfuzzer/rasterfuzzer.cc: New file. | |
|
3eb6f66a | 2016-03-01 07:10:30 | [autofit] Fix reallocation error introduced in 2016-02-27 (#47310). * src/autofit/aflatin.c (af_latin_hints_compute_segments): Reassign `prev_segment' after reallocation. | |
|
015c6e08 | 2016-03-01 06:45:52 | Fix clang warnings. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Use FT_UShort for `min_flags' and `max_flags'. Initialize `prev_*' variables. * src/cff/cffobjs.c (cff_face_init) [FT_DEBUG_LEVEL_TRACE]: Fix types of local variables. * src/smooth/ftgrays.c (gray_dump_cells) [FT_DEBUG_LEVEL_TRACE]: Update `printf' format string. * src/tools/ftfuzzer/ftfuzzer.cc (setIntermediateAxis): Add cast. (LLVMFuzzerTestOneInput): Fix loop type. | |

5c7646d2 | 2016-02-29 09:12:35 | [autofit] Add blue-zone support for Sinhala script. This essentially moves the Sinhala script from the `Indic' hinter to the `Latin' hinter. * src/autofit/afblue.dat: Add blue zone data for Sinhala. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Sinhala standard character and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Sinhala data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Sinhala data; in particular, use AF_WRITING_SYSTEM_LATIN. | |

f2169478 | 2016-02-28 22:48:34 | [autofit] Properly handle spikes pointing to the x-axis. An example that gets better rendered is glyph `uusignTaml' (glyph index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly handle segments where the last point of the first segment is identical to the first point in the second one. This can happen for malformed fonts or spikes. We either merge the new segment with the previous one (both segments point into the same direction), or we discard the shorter segment if they point into different directions. | |
|
ce486645 | 2016-02-27 15:01:49 | [autofit] Minor code clean-up. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Change some local variable names to better differentiate between values along a segment and values orthogonal to it. | |
|
ebfd7ce5 | 2016-02-26 08:10:41 | [autofit] Improve BOUND action. In complex glyph shapes, the original logic was too simple to cater for situations that would actually need something similar to PS Hint masks. This fix should alleviate the worst cases. * src/autofit/aflatin.c (af_latin_hint_edges): Don't allow complete disappearance of stems. |
