[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. |

[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. |

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. |

[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 |
|

|
available. |

[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. |

[base, truetype] New function `FT_Get_Var_Axis_Flags'. |
|
|
|
The reserved `flags' field got a value in OpenType version 1.8.2; |

|
corresponding element. Since we can't add a new field, we add an |

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; |
|
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). |

[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 |
|
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. |

[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. |

|
|
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. |

[sfnt, truetype] Always provide default instance. |
|
|
|
As documented in the OpenType specification, an entry for the |
|
default instance may be omitted in the named instance table. In |
|
particular this means that even if there is no named instance table |
|
in the font we actually do have a named instance, namely the default |
|
instance. |
|
|
|
For consistency, we always want the default instance in our list of |
|
named instances. If it is missing, we try to synthesize it. |
|
|
|
* src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default |

instance is in the table of named instances. Otherwise adjust |

[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. |

[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. |

[cff] Provide metrics variation service interface (#50196). |
|
|
|
Only now I've got an OTF with an HVAR table for testing... |
|
|
|
The code in `ftmm.c' uses `FT_FACE_LOOKUP_SERVICE' to get the |
|

|
`FT_FACE_FIND_GLOBAL_SERVICE' used in `sfnt_init_face'. |
