[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.

[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.

The reserved `flags' field got a value in OpenType version 1.8.2;

|
|
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.

[truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470).

|
|
|
|
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.
|
|

|
|
Initialize `autohint_metrics' and `autohint_mode' depending on

As documented in the OpenType specification, an entry for the

default instance may be omitted in the named instance table. In

in the font we actually do have a named instance, namely the default

|
instance.

named instances. If it is missing, we try to synthesize it.

[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.
