[type1] Allow (again) `/Encoding' with >256 elements (#52464).
|
||
|
||
In version 2.6.1, this has been disallowed to better reject
|
||
malformed fonts; however, this restriction was too strong. This
|
||
time, we only take the first 256 elements into account, since
|
||
encoding arrays are always accessed with a 8bit integer, according
|
||
to the PostScript Language Reference.
|
||
|
||
* src/type1/t1load.c (parse_encoding): Implement it.

it immediately afterwards); without this change, it can happen on my

[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.
|
||
|
||
* include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width'
|
||
field to pointer.
|

|

|
||
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

TrueType Auto v40

[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.

[cff, truetype] Adjust behaviour of named instances.

This commit completely separates the interaction between named

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
|
||
calculates prospective bitmap metrics for the given rendering mode.
|
||
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
|
||
Declare it.
|
||
|
||
* src/base/ftlcdfil.c (ft_lcd_padding): New helper function that adds
|
||
padding to CBox taking into account pecularities of LCD rendering.
|
||
* include/freetype/ftlcdfil.h (ft_lcd_padding): Declare it.
|
||
|
||
* src/raster/ftrend1.c (ft_raster1_render): Reworked to use
|
||
`ft_glyphslot_preset_bitmap'.
|
||
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
|
||
(ft_smooth_render_lcd, ft_smooth_render_lcd): The pixel_mode setting
|
||
is moved to `ft_glyphslot_preset_bitmap'.

[psaux] Move `psdecode' into `psobjs'.
|
||
|
||
As the former only contains a single procedure, move it into
|
||
`psobjs' for simplicity. Also change the parameter order to the
|
||
conventional one.
|
||
|
||
* src/psaux/psdecode.c (ps_decoder_init): Moved to...
|
||
* src/psaux/psobjs.c: ...Here.

[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
|
||
`initial_map_ready' boolean flag.
|

|
||
<cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_escHSTEM3, cf2_escVSTEM3>: Use

||
|
||
[psaux] Change subfont synthesis for CID fonts.
|
||
|
||
Change `t1_make_subfont' to take in the Private dict record as an
|
||
argument. This is because Type 1 and CID font records in FreeType
|
||
have this in different places.
|
||
|
||
* src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to
|
||
`FT_Face' so that CID is also accepted.
|
||
Take `PS_Private' as an argument and let caller figure out where the
|
||
Private dict actually is.
|
||
Update references.
|
||
|
||
* include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update
|

This concludes the changes needed to add Type 1 support.
|
||
|
||
* src/psaux/psintrp.c: Update includes.
|
||
(cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to
|
||
implied seac for CFF.
|
||
|
||
* src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New
|
||
function to look up the glyph index.
|
||
|
||
* src/psaux/psft.c (cf2_getT1SeacComponent,
|
||
cf2_freeT1SeacComponent): New functions to get the charstrings for
|
||
seac components.
|
||
|

|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString)
|
||
<cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1,
|
||
2).
|
||
<cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing
|
||
flex. This is to avoid closing the current contour.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|

|
||
[psaux] Extend Adobe interpreter (callothersubr).
|

* src/psaux/psintrp.c (cf2_interpT2CharString)
|
||
<cf2_escCALLOTHERSUBR>: Copy code from
|
||
`t1_decoder_parse_charstrings' (in `t1decode.c').
|
||
OtherSubr 3 (change hints) should reset the hintmask, so that the
|
||
new hints are applied.
|
||
Fix function calls and stack access.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|

[psaux] Extend Adobe interpreter (pop).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled
|
||
OtherSubr results are stored. Implement the PostScript stack using
|
||
an array.
|
||
<cf2_escPOP>: Ensure that the stack is not cleared after getting
|
||
`OtherSubr' results.
|
||
Fix stack access.
|

|
||
[psaux] Extend Adobe interpreter (callsubr).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>:

Type 1 mode.
|
||
|
||
* src/psaux/psft.c (cf2_initLocalRegionBuffer): Add Type 1 mode.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>

|
||
|
||
* 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
|
||
to ensure `div' and `callsubr' get values they can use.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[psaux] Extend Adobe interpreter (hints).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,
|
||
cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode.
|
||
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.
|
||
Correction for left sidebearing.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[psaux] Extend Adobe interpreter (hsbw, sbw).
|
||
|
||
* src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the
|
||
first operation in a Type 1 charstring.
|
||
(cf2_interpT2CharString): Remove unused variables.
|
||
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'
|
||
must be the first operation in a Type 1 charstring.

|
||
left sidebearing.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|

|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|

|
||
[psaux] Extend Adobe interpreter (closepath).
|
||
|
||
* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
|
||
Use the right builder function. We can use the `haveWidth' boolean
|
||
already present, instead of implementing `parse_state'.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[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.
|
||
|
||
NOTE: Will not compile in the meantime!
|
||
|
||
* src/psaux/psintrp.c: Add opcodes to enum.
|
||
(cf2_interpT2CharString): Copy relevant code over from
|
||
`t1_decoder_parse_charstrings' (in `t1decode.c').
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[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
|
||
are set properly.
|
||
|
||
* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a
|

2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[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
|
||
`cff_make_private_dict'.

|
||
|
||
* 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.
|

|
||
to choose which renderer to use.
|
||
|
||
* src/cid/cidgload.c (cid_load_glyph): Update call.
|
||
* src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update
|

|
||
Use the previously changed PS_Driver in type1 module to store
|
||
hinting engine configuration.
|
||
|
||
* include/freetype/ftt1drv.h: New file.
|
||
Duplicate and rename config options from CFF.

|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|
||
|
||
[cff] Move and rename `CFF_Driver'.
|
||
|
||
This is so that we can use the same hinting engine parameters for
|
||
Type 1.
|
||
|
||
* include/freetype/internal/cffotypes.h (CFF_Driver): Rename and
|
||
move to...
|
||
* include/freetype/internal/psaux.h (PS_Driver): ...here.
|
||
|
||
* src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c,

|
||
|
||
[psaux, type1] Reorganize object fields.
|
||
|

Make some fields more generic, so that we can access them the same
|
||
way regardless of Type 1 or CFF.
|
||
|
||
* include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face'
|
||
to `FT_Face'.
|
||
Remove unused fields.
|

|
||
Add some asserts to guard against casting `T1_Face' as `TT_Face'.
|
||
|
||
* src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow
|
||
`CFF_GlyphSlot', so that we can pretend they are the same in the
|
||
interpreter.
|
||
|
||
* src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point):
|
||
Updated with above changes.
|
||
|
||
2017-09-25 Ewald Hew <ewaldhew@gmail.com>
|

|
||
[psaux] Prepare for Type 1 mode.
|
||
|

[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.

The first 32bit of standard TrueType variants is 0x00010000,

OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources

starting 0xA5 followed by `kbd' or `lst'. Considering the following

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.

[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.

[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] 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).
|
||
|
||
* 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,
|
||
TT_Process_Composite_Component, load_truetype_glyph,
|
||
compute_glyph_metrics, TT_Load_Glyph): Updated.

|
||
|
||
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.

|
||

|
||
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.

(FT_New_Size): Allocate `internal' object.

[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.

[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.
