0ab2b62d | 2017-09-09 08:08:47 | [autofit] Improve communication with ftgrid. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Provide values in font units. | |
 |
3ef59e59 | 2017-09-09 01:28:24 | [base] Remove a check for resource ID in the resource fork driver. LastResort.dfont has a marginal resource ID 0xFFFF for sfnt resource. Inside Macintosh: More Macintosh Toolbox, `Resource IDs' (1-46), tells that some IDs are reserved and should not be used. FreeType2 just uses resource ID to sort the fragmented resource. To accept the marginal fonts, the checking is removed. * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id validity check, fix a trace message format. | |
|
5c4e40d7 | 2017-09-09 00:59:33 | [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst. | |

a3dd6d99 | 2017-09-05 23:02:04 | Fix multiple calls of `FT_Bitmap_Convert'. The documentation of `FT_Bitmap_Convert' says that multiple calls do proper reallocation of the target FT_Bitmap object. However, this failed for the sequence non-empty bitmap empty bitmap non-empty bitmap Reason was that `FT_Bitmap_Convert' only reallocated the bitmap buffer if it became too small; it didn't make the buffer smaller. For an empty bitmap following a non-empty one, only the buffer dimension got set to zero, without deallocation. If the next call was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was triggered. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target buffer to the correct size. * docs/CHANGES: Document it. | |
|
7d017ba8 | 2017-09-05 15:28:21 | [bdf] Fix size and resolution handling. * src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are missing. * docs/CHANGES: Document it. | |
|

|
e1d0249e | 2017-08-23 08:18:22 | [sfnt] Fix clang compilation (#51788). * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of scalars. (vector_shuffle): New macro to take of a different built-in function name on clang. | |
|
bd28952e | 2017-08-22 08:41:03 | [base] Don't zero out allocated memory twice (#51816). Patch applied from bug report. * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to avoid unnecessary overhead. | |
|
0aca17cf | 2017-08-22 08:25:14 | [truetype] Integer overflow. Changes triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107 * src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use NEG_LONG. | |
|

|
cadd29de | 2017-08-16 13:32:17 | * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings. | |
 |
c9d7c03f | 2017-08-15 08:48:17 | [sfnt] Speed up PNG image loading. This reduces the overhead of `premultiply_data' by 60%. * src/sfnt/pngshim.c (premultiply_data): Provide code which uses gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a time. | |
|
b45043c4 | 2017-08-11 09:34:20 | [sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available. | |
|
f2e121ab | 2017-08-10 12:56:50 | [base] Minor API improvement for default variation axis setting. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0. * docs/CHANGES: Updated. | |
|
c87fec02 | 2017-08-09 07:45:12 | [psnames] Really fix issue #49949. We now use a separate preprocessor macro to handle both definition and declaration of the glyph name arrays. * src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro. * src/tools/glnames.py (StringTable::dump, StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'. (dump_encoding): Ditto. (main): Use `wb' mode for writing the output file, which works on Windows also. * src/psnames/pstables.h: Regenerated. | |
|
410f3799 | 2017-03-09 00:08:38 | [smooth] Harmony LCD rendering. This is a new technology for LCD-optimized rendering. It capitalizes on the fact that each color channel grid is shifted by a third of a pixel. Therefore it is logical to render 3 separate monochrome bitmaps shifting the outline by 1/3 pixel, and then combine them. Importantly, the resulting output does not require additional LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_render_generic) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized rendering. * include/freetype/ftlcdfil.h, include/freetype/freetype.h, include/freetype/config/ftoption.h, devel/ftoption.h: Updated documentation. | |
|

f43b3094 | 2017-08-05 18:22:17 | [base, truetype] New function `FT_Get_Var_Axis_Flags'. The reserved `flags' field got a value in OpenType version 1.8.2; unfortunately, the public `FT_Var_Axis' structure misses the corresponding element. Since we can't add a new field, we add an access function. * src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function. * include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro. Updated. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory of `mmvar' to hold axis flags. Fill the axis flags array. * docs/CHANGES: Updated. | |
 |
24e256ab | 2017-08-04 08:25:31 | [truetype] Fix metrics of B/W hinting in v40 mode. Phantom points are now saved outside v40 backwards compatibility mode. This fixes the jumping glyphs when switching between v35 and v40 monochrome mode. * src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic. | |
|
7f44c2db | 2017-08-03 06:15:30 | [truetype] Do not set any ClearType flags in v40 monochrome mode. This fixes weird behavior of instructions that resulted in rendering differences between v35 and v40 in monochrome mode, e.g., in `timesbi.ttf'. * src/truetype/ttinterp.c (Ins_GETINFO) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check `subpixel_hinting_lean'. | |
|
7e508242 | 2017-08-01 12:44:35 | * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko. | |

|
ce367774 | 2017-08-01 08:24:51 | [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1. | |

fbe2fe4c | 2017-05-29 13:29:28 | Handle some integer overflow run-time errors (#46149, #48979). This commit (mainly for 32bit CPUs) is the first of a series of similar commits to handle known integer overflows. Basically, all of them are harmless, since they affect rendering of glyphs only, not posing security threats. It is expected that fuzzying will show up more overflows, to be fixed in due course. The idea is to mark places where overflows can occur, using macros that simply cast to unsigned integers, because overflow arithmetic is well defined in this case. Doing so suppresses run-time errors of sanitizers without adding computational overhead. * include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT, OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG, OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros. * src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply, FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled, ft_corner_orientation): Use new macros. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros. | |

2e4188d8 | 2017-05-28 07:46:22 | [cff] s/cf2_floatToFixed/cf2_doubleToFixed/. The new name better describes what the macro actually does; additionally, we don't need a trailing `f' for literals (there was only a single such instance in the code, but this caused a clang warning because the macro itself uses `double' literals). * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, src/cff/cf2font.c, src/cff/cf2hints.c: Updated. | |

ab2599ea | 2017-05-20 00:35:21 | [smooth] Implement minimal dynamic padding for LCD filtering. Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding. This change breakes current Skia (and Firefox). * include/freetype/internal/ftobjs.h (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic LCD padding. | |

a7f276a2 | 2017-05-15 00:25:37 | [autofit] Make autohint warping NORMAL option. This moves warping option from LIGHT to NORMAL mode. This makes LIGHT truly void of hinting in x-direction, with left side bearing never changed and right side bearing only altered by advance rounding. Therefore, LIGHT is now ready to return fractional advance. As a NORMAL option, warping substitutes normal hinting. * src/autofit/afcjk.c (af_cjk_hints_apply): Updated. * src/autofit/aflatin.c (af_latin_hints_apply): Updated. * src/autofit/aflatin2.c (af_latin2_hints_apply): Updated. * src/autofit/afloader.c (af_loader_load_glyph): Handle warping phantom points as normal. | |
