| |
| [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. |
| |
| 2017-09-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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. |

| 2017-09-05 Werner Lemberg <wl@gnu.org> |
| |
| 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. |
| |
| 2017-09-05 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |

| scalars. |
| (vector_shuffle): New macro to take care of a different built-in |
| function name on clang. |
| |
| 2017-08-22 Werner Lemberg <wl@gnu.org> |
| |

| |
| Patch applied from bug report. |
| |
| * src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to |
| avoid unnecessary overhead. |
| |
| 2017-08-22 Werner Lemberg <wl@gnu.org> |

| |
| [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. |
| |
| 2017-08-11 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2017-08-10 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2017-08-08 Werner Lemberg <wl@gnu.org> |
| |
| [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. |
| |
| 2017-08-08 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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 |

| 2017-08-05 Werner Lemberg <wl@gnu.org> |
| |
| [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. |

| 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [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. |
| |
| 2017-08-03 Nikolaus Waxweiler <madigens@gmail.com> |
| |
| [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'. |

| |
| [truetype] Fix loading of named instances. |
| |
| * src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position |
| while loading the `avar' table. |
| |
| 2017-08-01 Werner Lemberg <wl@gnu.org> |
| |
| [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. |

| |
| 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. |

| The new name better describes what the macro actually does; |

| warning because the macro itself uses `double' literals). |

| [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 breaks current Skia (and Firefox). |

| [autofit] Make autohint warping NORMAL option. |
| |
| This moves warping option from LIGHT to NORMAL mode. This makes LIGHT |

| Therefore, LIGHT is now ready to return fractional advance. As a |
| NORMAL option, warping substitutes normal hinting. |

| [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). |
| |
| When points are not touched by gvar interpolation deltas, FreeType |
| gave a slightly different result than Apple's CoreText. |
| |
| The OpenType working group will update the specification to document |
| the following behaviour: If the two points with deltas to the `left' |
| and `right' of the untouched point have the same coordinate, then |
| the inferred delta for the untouched point should be zero. |

| * src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new |
| behaviour. |

| [truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470). |
| |
| * src/truetype/ttobjs.h (TT_SizeRec): Add field `hinted_metrics' to |
| hold hinted metrics. |
| Make `metrics' a pointer so that `tt_glyph_load' can easily switch |
| between metrics. |
| |
| * src/truetype/ttdriver.c (tt_size_request): Updated. |
| (tt_glyph_load): Use top-level metrics if FT_LOAD_NO_HINTING is |
| used. |
| |
| * src/truetype/ttgload.c (TT_Hint_Glyph, TT_Process_Simple_Glyph, |

| |
| Add new `slight' auto-hinting mode. |
| |
| This mode uses fractional advance widths and doesn't scale glyphs |
| horizontally, only applying vertical scaling and hinting. |
| |
| At the same time, the behaviour of the `light' auto-hinter gets |
| restored for backward compatibility: Both vertical and horizontal |
| scaling is again based on rounded metrics values (this was changed |
| in a commit from 2017-03-30 as a side effect). To be more precise, |
| the behaviour is restored for TrueType fonts only; for other font |
| formats like Type 1, this is a new feature of the `light' hinting |
| mode. |
| |
| * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. |
| (FT_RENDER_MODE_SLIGHT): New render mode. |
| |
| * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add |
| `autohint_mode' and `autohint_metrics' fields. |
| |
| * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c |
| (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): |
| Updated. |
| |
| * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use |
| `autohint_metrics'. |
| (af_loader_load_glyph): s/internal/slot_internal/. |
| Initialize `autohint_metrics' and `autohint_mode' depending on |
| current auto-hint mode. |
| Use `autohint_metrics'. |
| Updated. |
| |
| * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. |
| |
| * src/base/ftobjs.c (FT_Load_Glyph): Updated. |

| Introduce `FT_Size_InternalRec' structure. |
| |
| We are going to extend this later on. |
| |
| * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): New |
| structure with a single field `module_data'. |
| |
| * src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of |
| `FT_Size' structure. |

| (due to the changes in `Ins_FDEF' and `Ins_IDEF'). This change can |
| enormously speed up handling of broken fonts. |

| |
| * src/truetype/ttdriver.c (tt_size_request): Revert change from |
| 2011-07-16; the intended metrics fix seems now to be implemented in |
| a different way, making the patch unnecessary. Note that this |

| * src/psaux/t1decode.c (t1_decoder_parse_charstrings) |
| <callothersubr>: Since there is not a single flex operator but a |
| series of subroutine calls, malformed fonts can call arbitrary other |
| operators after the start of a flex, possibly adding points. For |
| this reason we have to check the available number of points before |
| inserting a point. |

| |
| [sfnt, truetype] Always provide default instance. |
| |
| As documented in the OpenType specification, an entry for the |

| |
| [autofit] Prevent overlapping blue zones. |
| |
| Problem reported as |
| |
| https://github.com/google/fonts/issues/632 |
| |
| The font in question (Nunito) has values 705 and 713 for the |
| reference and overshoot values, respectively, of the first blue |
| zone. Blue zone 2, however, has value 710 for both the reference |
| and overshoot. At 12ppem, reference and overshoot of blue zone 0 |
| becomes 8px, while blue zone 2 becomes 9px. |
| |
| A peculiarity of this font is that the tops of isolated vertical |
| stems like `N' have a slight overshoot also. The auto-hinter tries |
| to find the nearest blue zone using the *original* coordinates. For |
| vertical stems, this is value 713. For normal horizontal tops like |
| in character `E', this is value 710. Since value 713 is mapped to |
| 8px but value 710 to 9px, `N' and similar characters are one pixel |
| higher than `E', which looks very bad. |
| |
| This commit sanitizes blue zones to avoid such a behaviour. |
| |
| * src/autofit/aflatin.c (af_latin_sort_blue): New function. |

| [autofit] Use better blue zone characters for lowercase latin. |
| |
| The number of lowercase characters for computing the top flat blue |
| zone value was too small (in most cases only `x' and `z'). If one |
| of the two characters has a large serif, say, it can happen that |
| FreeType must select between two different values, having a 50% |
| chance to use the wrong one. As a result, rendering at larger PPEM |
| values could yield uneven lowercase glyph heights. |
