[autofit] Fix interface of `af_get_char_index'.
|
|
|
|

[autofit] Don't combine multiple features into one set.
|
|
|
|
|
|
|
|
|
|
|
|
Combining them, as originally envisioned, would lead to much more
|
|
|
|
|
|
complicated code, as investigations have shown meanwhile. The major
|
|
|
|
|
|
drawback is that we run out of available style slots much earlier.
|
|
|
|
|
|
However, this is only a theoretical issue since we don't support a
|
|
|
|
|
|
large number of scripts currently.
|
|
|
|
|
|
|
|
|
|
|
|
* src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
|
|
|
|
|
|
a single-element `COVERAGE' macro, sort the elements by the feature
|
|
|
|
|
|
tags, and add entry for `ruby'.

[ftrfork] Fix the face order difference between POSIX and Carbon.
|
|
|
|
|
|
|
|
|
|
|
|
The fragmented resources in Suitcase and .dfont should be reordered
|
2013-12-27 18:18:49 +00:00
|
|
|
|
when `POST' resource for Type1 is being restored, but reordering of
|
2013-12-27 07:44:24 +00:00
|
|
|
|
sfnt resources induces the different face order. Now the ordering
|
2013-12-27 18:18:49 +00:00
|
|
|
|
is restricted to `POST' resource only, to prevent the different
|
|
|
|
|
|
order issue (e.g. the face index in the fontconfig cache generated
|
|
|
|
|
|
with Carbon framework is incompatible with that by FreeType 2
|
|
|
|
|
|
without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung.

|

|
|
|
[autofit] Introduce `coverages'.
|
|
|
|
|
|
|
|
|
|
|
|
Coverages are the interface to the HarfBuzz library to acces
|
|
|
|
|
|
OpenType features for handling glyphs not addressable by the cmap.
|
|
|
|
|
|
|
|
|
|
|
|
Right now, compilation of HarfBuzz is only added to the development
|
|
|
|
|
|
build. A solution for standard build mode will be delayed until
|
|
|
|
|
|
HarfBuzz gets split into two libraries to avoid mutual dependencies
|
|
|
|
|
|
between FreeType and HarfBuzz.
|
|
|
|
|
|
|
|
|
|
|
|
Note that this is only a first step in handling coverages, basically
|
|
|
|
|
|
providing the framework only. Code for handling selected OpenType
|
|
|
|
|
|
features (this is, actually using the data in `afcover.h') will
|
|
|
|
|
|
follow.

[truetype] Next round in phantom point handling.
|
|
|
|
|
|
|
|
|
|
|
|
Greg Hitchcock provided very interesting insights into the
|
|
|
|
|
|
complicated history of the horizontal positions of the TSB and BSB
|
|
|
|
|
|
phantom points.

[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
|
|
|
|
|
|
`grayscale_hinting' flags as conditionals for the x position of TSB
|
|
|
|
|
|
and BSB.

are rounded horizontally, vertical ones are rounded vertically.
|
|
|
|
|

[truetype] Fix change from 2013-11-20.
|

Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
|
|
|
|
|
|
|
|
|
|
|
|
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to

`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
|
|
|
|
|
|
`IS_HINTED' clause.
|
|
|
|
|
|
Also remove redundant check using `maxSizeOfInstructions' – in
|
|
|
|
|
|
simple glyphs, the bytecode data comes before the outline data, and
|
|
|
|
|
|
a validity test for this is already present.

Simplify header file hierarchy.
|
|
|
|
|
|
|
|
|
|
|
|
This large patch changes the header file directory layout from
|
|
|
|
|
|
`include/freetype/...' to `include/...', effectively removing one
|
|
|
|
|
|
level. Since the file `ft2build.h' is also located in `include'
|
|
|
|
|
|
(and it stays there even after installation), all FreeType header
|
|
|
|
|
|
files are now in a single directory.
|
|
|
|
|
|
|
|
|
|
|
|
Applications that use (a) `freetype-config' or FreeType's
|
|
|
|
|
|
`pkg-config' file to get the include directory for the compiler, and
|
|
|
|
|
|
(b) the documented way for header inclusion like
|
|
|
|
|
|
|
|
|
|
|
|
#include <ft2build.h>
|
|
|
|
|
|
#include FT_FREETYPE_H
|
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
|
|
don't need any change to the source code.

[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly

should check the code accordingly.

[arm] Fix thumb2 inline assembly under LLVM.
|
|
|
|
|
|
|
|
|
|
|
|
When using `ADD' with an immediate operand, the instruction is
|
|
|
|
|
|
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
|
|
|
|
|
|
immediate operand cannot exceed 4095. It will fail to compile with
|
|
|
|
|
|
LLVM.
|
|
|
|
|
|
|
|
|
|
|
|
However, in GCC, due to some legacy compatibility considerations,
|
|
|
|
|
|
`ADD.W' will be automatically emitted when the immediate operand is
|
|
|
|
|
|
larger than 4095.

Note that the old code avoided using a region of the piecewise
|
|
|
|
|
|
linear function where the slope was zero. The recovery was to use a
|
|
|
|
|
|
different section of the function, which produced a different,
|
|
|
|
|
|
incorrect amount of darkening.

|
|
|
|
This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
|
|
|
|
|
|
is to use a previous darkening amount when producing an unhinted,
|
|
|
|
|
|
unscaled outline. This can cause autohint samples in ftgrid and
|
|
|
|
|
|
ftview to be based on darkened CFF outlines instead of unhinted,
|
|
|
|
|
|
undarkened ones.
|
|
|
|
|
|
|
Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).

Fix Savannah bug #39295.
|
|
|
|
|
|
|
|
|
|
|
|
The bug was caused by switching to the initial hintmap (the one in
|
|
|
|
|
|
effect when `moveto' executes) just before drawing the final element
|
|
|
|
|
|
in the charstring. This ensured that the path was closed (in both
|
|
|
|
|
|
Character Space and Device Space). But if the final element was a
|
|
|
|
|
|
curve and if the final hintmap was different enough from the initial
|
|
|
|
|
|
one, then the curve was visibly distorted.
|
|
|
|
|
|
|
|
|
|
|
|
The first part of the fix is to draw the final curve using the final
|
|
|
|
|
|
hintmap as specified by the charstring. This corrects the
|
|
|
|
|
|
distortion but does not ensure closing in Device Space. It may
|
|
|
|
|
|
require the rasterizer to automatically generate an extra closing
|
|
|
|
|
|
line. Depending on the hintmap differences, this line could be from
|
|
|
|
|
|
zero to a couple pixels in length.
|
|
|
|
|
|
|
|
|
|
|
|
The second part of the fix covers the case where the charstring
|
|

|

subpath is closed with an explicit line. We now modify that line's

FT_Open_Face: Improve external stream handling.
|
|
|
|
|
|
|
|
|
|
|
|
If the font's `clazz->init_face' function wants to swap to new

stream, handling of whether original stream was external could
|
|
|
|
|
|
result to either memory leak or double free. Mark externality into
|
|
|
|
|
|
face flags before calling `init_face' such that the clazz can handle
|
|
|
|
|
|
external streams properly.

Better tracing of loaded glyphs.
|
|
|
|

|

Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.

Previously, the loading of a glyph was traced at level 4, if at all.
|
2013-08-26 10:55:48 +00:00

at level 1, making it easier to select tracing output (for example

|
|

using F2_DEBUG="any:1 afhints:7 aflatin:7").

[autofit] Introduce data file for blue strings.
|
|
|
|
|
|
|
|
|
|
|
|
The idea is to have a central file which gets processed by a Perl
|
|
|
|
|
|
script to create proper `.c' and `.h' files using templates. There
|
|
|
|
|
|
are two other reasons to do that:
|
|
|
|
|
|
|
|
|
|
|
|
. The data file should be easily readable. We use UTF-8 encoding
|
|
|
|
|
|
which then gets converted to single bytes.
|
|
|
|
|
|
|
|
|
|
|
|
. Since the number of supported scripts will increase soon, the
|
|
|
|
|
|
current usage of blue string arrays is a waste of space. Using
|
|
|
|
|
|
the Perl script it is possible to imitate jagged arrays,
|
|
|
|
|
|
defining enumeration constants as offsets into the arrays.
|
|
|
|
|
|
|
|
|
|
|
|
This commit only adds files without changing any functionality.

Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).

to indicate that we synthesize a closepath line.

space to device space.

[autofit] Improve handling of `near' points.

Points which are very near to each other are now marked as such.

first and the `out' vector of the last point of a group of near
|
|
|
|
|
|
points.

[autofit] Introduce `writing systems'.
|
|
|
|
|
|
|
|
|
|
|
|
This patch adds a new top level to the auto-hinter's script class
|
|
|
|
|
|
hierarchy. It defines `writing systems' which can contain multiple
|
|
|
|
|
|
scripts.
|
|
|
|
|
|
|
|
|
|
|
|
For example, the `latin' writing system (in file `aflatin.c') is
|
|
|
|
|
|
able to support scripts like Latin, Cyrillic, Armenian, etc., which
|
|
|
|
|
|
can be handled similarly.
|
|
|
|
|
|
|
|
|

Scripts are now named using four-letter OpenType tags.

Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.

subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.

Optimize FT_MulFix for x86_64 GCC builds.
|
|
|
|
|
|
|
|
|
|
|

This patch provides an optimized `FT_MulFix' implementation for

|
x86_64 machines when FreeType is built with GCC, or compatible
|
|
|
|
|
|
compilers like Clang.

Speed up ARMv7 support.
|
|
|
|
|
|
|
|
|
|
|
|
When building for ARMv7 with thumb2 instructions, the optimized
|
|
|
|
|
|
`FT_MulFix_arm' assembly routine was not being used.
|
|
|
|
|
|
|
|
|
|
|
|
The reason for this is in the `ftconfig.h' header, namely:
|
|
|
|
|
|
|
|
|
|
|
|
- The assembly routine uses the `smull' instruction which is not
|
|
|
|
|
|
available when generating Thumb-1 machine code. It is available
|
|
|
|
|
|
in Thumb-2 mode, though.
|
|
|
|
|
|
|
|
|
|
|
|
- The header was written a long time ago before Thumb-2 became
|
|
|
|
|
|
widely popular (e.g. with Android). So it simply doesn't use the
|
|
|
|
|
|
assembly routine if the `__thumb__' built-in macro is defined.
|
|
|
|
|
|
|
|
|
|
|
|
- When compiling in Thumb-2 mode, the compiler will define both
|
|
|
|
|
|
`__thumb__' and `__thumb2__'.
|
|
|
|
|
|
|
|
|
|
|
|
By checking for `(__thumb2__ || !__thumb__)', we ensure that the
|
|
|
|
|
|
assembly routine is only avoided when generating Thumb-1 code.
|
|
|
|
|
|
|
|
|
|
|
|
Given that this is performance-sensitive function, this improves

FreeType can either crash due to a NULL dereference or leak memory.

|
reference count is set to 1, a subsequent `FT_Done_Library' call

Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification
https://color-emoji.googlecode.com/git/specification/v1.html
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images. If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.
Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.
