[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

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.
|
||
|

|
||
|
||
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.
|
||
|
||

|
||
missing.

[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.
|
||
|

[psnames] Really fix issue #49949.
|
||
|

We now use a separate preprocessor macro to handle both definition
|

|
||
|
||
* src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.
|
||
|
||
* src/tools/glnames.py (StringTable::dump,

StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.

[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

[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.

|
||
|
||
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.

[autofit] Fix metrics computation.
|
||
|
||
Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and
|
||
Nikolaus Waxweiler <madigens@gmail.com>.
|
||
|
||
* src/base/ftobjs.c (FT_Request_Size): Trigger recomputation of
|
||
auto-hinter metrics. Without this change, multiple size changing
|
||
calls for a single face fail.
|
||
|
||
2017-04-29 Werner Lemberg <wl@gnu.org>
|
||
|
||
* src/truetype/ttdriver.c (tt_size_request): Properly check `error'.

|
||
|
||
Introduce AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option.
|
||
|
||
* include/freetype/config/ftoption.h
|
||
(AF_CONFIG_OPTION_TT_SIZE_METRICS): New option, commented out by
|
||
default.
|
||
|
||
* src/autofit/afloader.c (af_loader_load_glyph): Use
|
||
AF_CONFIG_OPTION_TT_SIZE_METRICS to guard the corresponding code.

[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,

|
||
|
||
* src/truetype/ttobjs.c (tt_size_reset): Updated.
|

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
|
||
`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.
|
||
(FT_New_Size): Allocate `internal' object.

|
||
|
||
Introduce `FT_Size_InternalRec' structure.

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

[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.

[truetype] Fix linear metrics of GX variation fonts (#49829).
|
||
|
||
When asking for an unhinted non-default variations,
|

`linearVertAdvance' is currently the value from the `hmtx' table
|
||
instead of the actual value after applying the variation. `HVAR'
|
||
support fixes this, but fonts will exist without that table and will
|
||
need sane fallback.

[gzip] Improve building with external zlib (#49673).
|
||
|
||
Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
|
||
the following error.
|
||
|
||
ftgzip.c
|
||
zlib-1.2.8\zlib.h(86): error C2061:
|
||
syntax error: identifier 'z_const'
|
||
zlib-1.2.8\zlib.h(94): error C2054:
|
||
expected '(' to follow 'z_const'
|
||
zlib-1.2.8\zlib.h(94): error C2085:
|
||
'msg': not in formal parameter list
|
||
...
|
||
zlib-1.2.8\zlib.h(877): fatal error C1003:
|
||
error count exceeds 100; stopping compilation
|
||
|
||
The error happens because FreeType keeps an own copy of zlib-1.1.4
|
||
under `src/gzip'. When building `src/gzip/ftgzip.c' with
|
||
FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
|
||
|
||
#include <zlib.h>
|
||
|
||
which correctly finds an external `zlib.h', but `zlib.h' itself has
|
||
a line
|
||
|
||
#include "zconf.h"
|
||
|
||
which makes Visual Studio 2015 find `src/gzip/zconf.h' while
|
||
compiling the files in `src/gzip'.
|
||
|
||
* src/gzip/zconf.h: Rename to...
|
||
* src/gzip/ftzconf.h: ... this.

[sfnt] Improve FT_LOAD_BITMAP_METRICS_ONLY for `sbix' format.
|
||
|
||
It's unavoidable to call the PNG engine, but to get the metrics it
|
||
is sufficient to read the PNG image's header only.
|
||
|
||
* src/sfnt/pngshim.c (Load_SBit_Png): Add argument to control the
|
||
allocation of the glyph slot.
|

* src/sfnt/pngshim.h: Updated.
|
||
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_png,

[sfnt] Speed up `sbix' lookup.
|
||
|
||
This also fixes a bug introduced in 2016-10-01 which prevents
|
||
display of embedded bitmap fonts that use the `sbix' format.
|
||
|
||
* src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and
|
||
offset also in `ebdt_size' and `ebdt_start', respectively. This
|
||
makes the test for an embedded bitmap data table succeed for this
|
||
format.
|
||
|
||
(tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use
|
||
`ebdt_size' and `ebdt_start'
|

Werner Lemberg <wl@gnu.org>
|
||
|
||
Introduce a way of quickly retrieving (embedded) bitmap metrics.
|
||
|
||
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
|
||
until the user calls `FT_Render_Glyph'. However, it always
|
||
allocates memory for bitmaps and copies or decodes the contents of a
|
||
bitmap glyph, which can be quite slow for PNG data.
|
||
|
||
* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
|
||
macro.
|
||
|
||
* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
|
||
FT_LOAD_BITMAP_METRICS_ONLY is used.
|
||
|
||
* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,

tt_face_load_sbit_image): Updated.

`FT_LOAD_BITMAP_METRICS_ONLY' is set.
|
||
|
||
* src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add

[pcf] Enrich family name with foundry name and glyph width info.
|
||
|
||
This is a very old patch from openSuSE (from 2006, submitted to
|
||
FreeType in 2011) that I forgot to apply.
|
||
|
||
https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
|
||
|
||
Prepend the foundry name plus a space to the family name. There are
|
||
many fonts just called `Fixed' which look completely different, and
|
||
which have nothing to do with each other. When selecting `Fixed' in
|
||
KDE or Gnome one gets results that appear rather random, the style
|
||
changes often if one changes the size and one cannot select some
|
||
fonts at all.
|
||
|
||
We also check whether we have `wide' characters; all put together,
|
||
we get family names like `Sony Fixed' or `Misc Fixed Wide'.
|
||

|
||
of twilight points, the total number of negative jumps, and the

total number of loops in LOOPCALL opcodes. The values are based on

the number of points and entries in the CVT table.
|

|
||
|
||
[truetype] Sanitize only last entry of `loca' table.
|
||
|
||
Without this patch, a loca sequence like `0 100000 0 100000 ...',
|
||
where value 100000 is larger than the `glyf' table size, makes
|
||
FreeType handle the whole `glyf' table as a single glyph again and
|
||
again, which is certainly invalid (and can be very slow, too).
|
||
|
||
* src/truetype/ttpload.c (tt_face_get_location): Implement.

||
Improve tracing messages.

that is wasteful.

|
||
* src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better

[smooth] Simplify span rendering more.
|
||
|
||
It turns out that there is significant cost associated with `FT_Span'
|
||
creation and calls to `gray_render_span' because it happens so
|
||
frequently. This removes these steps from our internal use but leaves
|
||
it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
|
||
is about 5%.
|
||
|
||
* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
|
||
migrated to...
|
||
(gray_hline): ... here.

|
||
|
||
* src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.

[smooth] Simplify span rendering.
|

`font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
|

set that value for bitmap fonts and the advance gets scaled to zero.

[truetype] Add bytecode support for GX variation fonts.
|

This commit implements undocumented (but confirmed) stuff from
|
||
Apple's old bytecode engine.
|
||
|
||
GETVARIATION[], opcode 0x91
|
||
This opcode pushes normalized variation coordinates for all axes

onto the stack (in 2.14 format). Coordinate of first axis gets
|
||
pushed first.
|
||
|
||
GETINFO[], selector bit 3

||
If GX variation support is enabled, bit 10 of the result is set
|
||
to 1.

* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
|
||
|
||
`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.

|
||
[autofit] Update and improve segment and edge tracing.
|
||
|
||
* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
|
||
`delta' also.
|
||
Don't show first point of segment as a replacement for `pos'; this
|
||
is (a) misleading, since the difference to `pos' can be almost
|
||
arbitrarily large in corner cases, and (b) it is better to have all
|
||
segment data in font units instead of a single value given in output
|
||
space coordinates.
|
||
Improve layout.
|
||
(af_glyph_hints_dump_edges): Show px->units and units->px conversion
|
||
values for convenience.
|
||
Improve layout.

|
||
|
||
[autofit] For edges, reject segments wider than 1px (#41334).
|
||
|
||
* src/autofit/afhints.h (AF_SegmentRec): New member `delta'.
|
||
|
||
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute
|
||
`delta'.
|
||
(af_latin_hints_compute_edges): Reject segments with a delta larger
|
||
than 0.5px.
|
||
|
||

|
||
|
||
* include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.
|
||
|
||

|
||
|
||
[sfnt] Fix `face_index' value in `FT_Face' for named instances.
|
||
|
||
* src/sfnt/sfobjs.c (sfnt_init_face): Don't strip off higher 16bits.
|
||
|
||

|
||
|
||
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
|
||
|
||

|
||
|
||
[truetype] Fix gxvar delta interpolation.
|
||
|
||
The coordinates of the base font should be used for interpolation
|
||
purposes, NOT the current points (i.e., the result of accumulation
|
||
of previous deltas).
|
||
|
||
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
|
||
`points_org' before looping over all tuples.
