[psaux] Fix Type 1 glyphs with too many stem hints.
|
||
|
||
According to the CFF specification, charstrings can have up to 96 stem
|
||
hints. Due to hint replacement routines in Type 1 charstrings, some
|
||
glyphs are rejected by the Adobe engine, which implements the above
|
||
limit. This fix turns off hinting for such glyphs.
|
||
|
||
* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
|
||
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
|
||
hinting.
|

|
||
2018-01-06 Werner Lemberg <wl@gnu.org>
|
||
|

Add `FT_Done_MM_Var'.
|
||
|
||
This is necessary in case the application's memory routines differ
|

from FreeType. A typical example is a Python application on Windows
|

that calls FreeType compiled as a DLL via the `ctypes' interface.
|
||
|
||
* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare

[sfnt] Fix charmap type 2 iterator (#52646).
|
||
|
||
The subsetted demo font of the report that exhibits the bug has a
|
||
very unusual type 2 cmap for Unicode(!): It contains only two
|
||
sub-headers, one for one-byte characters (covering the range 0x20 to
|
||
0xFA), and a second one for higher byte 0x01 (just for character
|
||
code U+0131).

Before this commit, the iterator wasn't able to correctly handle a
|
||
sub-header for higher byte 0x01.

[psaux] Fix CFF advance widths. (#52466)
|
||
|
||
Glyph advance widths were being written to the new `PS_Decoder' but not

saved to the underlying format specific decoder. This caused pure CFF
|

fonts to have bad advance width.

|
||
Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
|
||
|
||
Since Ewald Hew factored the Adobe hinting engine out of the CFF
|
||
driver code, we can now use it on Type 1 (and CID) font formats, as
|
||
both have the same hinting philosophy.
|
||
|
||
This change activates the Adobe hinter when in LIGHT mode, and
|
||
therefore always unless explicitly asking for the auto-hinter. This
|
||
makes LIGHT behavior consistent with CFF fonts. As of this commit,
|
||
the hinting engine table looks as follows.
|
||
|
||
LIGHT NORMAL

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251)
|
||
|
||
The interpreter in Type 1 mode rewinds the charstring after collecting
|
||
all hints for building the initial hintmap (commit d52dd7f). However,
|
||
some charstrings use `endchar' in a final subroutine call, rewinding to
|
||
the start of that subroutine, and only a small section of the actual
|
||
glyph is drawn.
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>:

[smooth] Fix complex rendering at high ppem.
|

We used to split large glyphs into horizontal bands and continue

bisecting them still horizontally if that was not enough. This is
|
||
guaranteed to fail when a single scanline cannot fit into the
|
||
rendering memory pool. Now we bisect the bands vertically so that
|

the smallest unit is a column of the band height, which is guranteed

to fit into memory.

Bitmap metrics presetting [1/2].
|
||
|
||
This mainly just extracts the code for presetting the bitmap metrics
|
||
from the monochrome, grayscale, and LCD renderers into a separate
|
||
function.
|
||
|
||
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): New function that

[psaux] Fix Type 1 hinting.
|
||
|
||
Type 1 hinting breaks sometimes when mid-charstring hints should
|
||
have been in the initial hintmap. This fix adds a preprocessing
|
||
pass that reads all hints and builds the correct initial hintmap
|
||
first, before proceeding to build the glyph outline.
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString): New

have this in different places.
|
||
|
||
* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to

|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add
|
||
Type 1 mode. Type 1 requires large integers to be followed by
|
||
`div'; cf. `Adobe Type 1 Font Format', section 6.2.
|
||
<op == 255>: Push Type 1 four-byte numbers as `Int' always. This is
|

|
||
Allow adding hints mid-charstring.
|
||
<cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands
|
||
for three normal stem hints. This requires some recalculation of
|
||
stem positions.

(cf2_interpT2CharString): Remove unused variables.
|
||
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'

[psaux] Add Type 1 operations to Adobe CFF interpreter.
|
||
|
||
The following Type 1 specific ops have been added (copied from
|
||
`t1decode'):
|
||
|
||
closepath
|
||
vstem3
|
||
hstem3
|
||
seac
|
||
sbw
|
||
callothersubr
|
||
pop
|
||
setcurrentpoint
|
||
hsbw
|
||
|
||
The following require a Type 1 mode, because of differences in
|
||
specification:
|
||
|
||
hstem
|
||
vstem
|
||
vmoveto
|
||
callsubr
|
||
div
|
||
rmoveto
|
||
hmoveto
|

Numbers
|
||
|
||
The subsequent commits will implement these changes and adapt
|
||
accesses of data and objects to the new interpreter.

|
||
|
||
[type1] Fixes for rendering.
|
||
|
||
The Type 1 advance width calculation passes null for glyph slot,
|
||
etc, which can cause null pointer access in the new interpreter.
|
||
Fall back to the old one for now.
|
||
|
||
Fix the large glyph retry code and ensure hinting and scaling flags
|

|
||
[psaux] Add missing objects (2/2).
|
||
|
||
Synthesize a `SubFont' object for Type 1 fonts. This is used in the
|
||
interpreter to access Private dict data, which are stored in
|
||
different places for Type 1 and CFF. This allows the same data to
|
||
be used in either mode.
|
||
|
||
* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy
|
||
required values to a dummy `CFF_SubFont' object. This is similar to

|
||
|
||
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto.

[psaux] Add missing objects for Type 1 (1/2).
|
||
|
||
Move `CF2_Font' instance to `PS_Decoder'. This is the context for
|
||
the interpreter and since it is currently stored in `CFF_Font', is
|
||
unavailable in Type 1 mode.
|
||
|
||
* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New
|
||
`cf2_instance' field.
|

||
|
||
* include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change

[cff] Fix family name logic of pure CFF fontdata (#52056).
|
||
|
||
1. If `FamilyName' is present in the CFF font, use this for
|
||
FT_Face's `family_name'.
|
||
2. Otherwise, use the face name and chop off any subset prefix.
|
||
3. If at this point FT_Face's `family_name' is set, use this
|
||
together with the full name to determine the style.
|
||
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
|
||
5. If we don't have a valid style, use "Regular".
|
||
|
||
Previously, FT_Face's `family_name' entry for pure CFF fontdata
|
||
nearly always was the fontname itself, instead of the `FamilyName'
|
||
entry in the CFF font (assuming there is one).
|
||
|
||
* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

[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

[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

simple missing bitmap.
|
||
|
||
* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a

[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.

[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).

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

Make `metrics' a pointer so that `tt_glyph_load' can easily switch

2017-04-22 Werner Lemberg <wl@gnu.org>
|
||
|
||
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

||

* 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

* 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.

[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.
|
||
|
||
Problem reported by Christoph Koeberlin <christoph@koe.berlin>.
