[autofit] Add blue-zone support for Devanagari.
|

[autofit] Introduce neutral blue zones to the latin module.
|
||
|
||
Such blue zones match either the top or the bottom of a contour. We
|
||
need them for scripts where accent-like elements directly touch the
|

[autofit] Fix Savannah bug #42148.
|
||
|
||
The adaptation of the cjk auto-hinter module to blue stringsets in
|
||
2013-08-25 had three severe bugs. Mea culpa.
|
||
|
||
1. Contrary to the latin auto-hinter, characters for reference and
|
||
overshoot values of a blue zone are specified separately. Due to
|
||
the screwed-up change it didn't work at all.
|
||
|
||
2. A boolean comparison was erroneously replaced with a cast,
|
||
causing invalid results with the `^' operator later on. The
|
||
visual artifact caused by this problem is the topic of the bug
|
||
report.
|
||
|
||
3. Two flag values were inverted, causing incorrect assignment of
|
||
reference and overshoot values.
|
||
|
||
* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
|
||
syntax to have both reference and overshoot characters in a single
|
||
string. This is error #1.
|
||
Add extensive comments.
|
||
|
||
* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
|
||
longer used.
|
||
(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
|
||
This is error #3.
|
||
|
||
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
|
||
|
||
* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
|
||
Use character `|' to separate characters for reference and overshoot
|
||
values.
|
||
Improve tracing messages, synchronizing them with the latin
|
||
auto-hinter.
|
||
(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
|
||
This is error #2.
|
||
(af_cjk_align_linked_edge): Add tracing message.
|
||
|
||
* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
|
||
used.
|
||
|
||
2014-04-17 Werner Lemberg <wl@gnu.org>
|
||
|
||
[autofit] More coverage fixes for complex scripts.
|
||
|
||
* src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage
|
||
of GSUB lookups into output coverage. Otherwise, ligatures are not
|
||
handled properly.
|
||
Don't check blue zone characters for default coverage.
|
||
|
||
2014-04-17 Werner Lemberg <wl@gnu.org>
|
||
|
||
Make `FT_Get_SubGlyph_Info' actually work.

||
|
||
* src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok
|
||
if there is no error.
|
||
|
||
2014-04-15 Werner Lemberg <wl@gnu.org>
|
||
|
||
[afblue.pl]: Minor improvements.
|
||
|
||
* src/tools/afblue.pl: Allow whitespace before comments.
|
||
Ignore whitespace in strings.

||
[autofit] Improve coverage handling.
|
||
|
||
* src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs
|
||
appearing in the GPOS table if we are processing the default
|
||
coverage.
|
||
|
||

|
||
|
||
[smooth] Fix stand-alone compilation.
|
||
|
||

|
||
|
||
2014-04-12 Werner Lemberg <wl@gnu.org>
|
||
|
||
[autofit] Redesign the recognition algorithm of strong points.
|
||
|
||
In particular, local extrema without horizontal or vertical segments
|
||
are better recognized:
|
||
|
||
+ A + D
|
||
\ /
|
||
\ /
|
||
\ /
|
||
\ /
|
||
\ + C
|
||
\ /
|
||
B +/
|
||
|
||
If the distances AB and CD are large, point B wasn't previously
|
||
detected as an extremum since the `ft_corner_is_flat' function
|
||
`swallowed' BC regardless of its direction, tagging point B as weak.
|
||
The next iteration started at B and made `ft_corner_is_flat' swallow
|
||
point C, tagging it as weak also, et voilà.
|
||
|
||
To improve that, another pass gets now performed before calling
|
||
`ft_corner_is_flat' to improve the `topology' of an outline: A
|
||
sequence of non-horizontal or non-vertical vectors that point into
|
||
the same quadrant are handled as a single, large vector.
|
||
|
||
Additionally, distances of near points are now accumulated, which
|
||
makes the auto-hinter handle them as if they were prepended to the
|
||
next non-near vector.
|
||
|
||
This generally improves the auto-hinter's rendering results.
|
||
|
||
* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
|
||
|
||
* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
|
||
`AF_FLAG_NEAR'.

||

||

||
|
||
[autofit] Improve scoring algorithm for identifying stems.
|
||
|
||
Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
|
||
|
||
The new algorithm takes care of the width of stems: If the distance
|
||
between two segments is larger than the largest stem width, the
|
||
demerits quickly increase for larger distances. This improves
|
||
hinting of slanted fonts (especially if the inner parts of serifs
|
||
have non-horizontal `shoulders'), avoiding false stem links.
|
||
|
||
* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest
|
||
stem width (if available) to compute better demerits for distances
|
||
between stems.
|
||
(af_latin_hints_detect_features): Pass stem width array and array
|
||
size.
|
||
(af_latin_metrics_init_widths): Updated to use original algorithm.
|
||
(af_latin_hints_apply): Updated to use new algorithm.
|
||
|
||
* src/autofit/aflatin.h: Updated.
|
||
* src/autofit/afcjk.c: Updated.

Fix Savannah bug #38235.
|
||
|
||
Work around a bug in pkg-config version 0.28 and earlier: If a
|
||
variable value gets surrounded by doublequotes (in particular values
|
||
for the `prefix' variable), the prefix override mechanism fails.
|
||
|
||
* builds/unix/freetype2.in: Don't use doublequotes.
|
||
* builds/unix/unix-def.in (freetype.pc): Escape spaces in directory
|

[bdf] Fix Savannah bug #41692.
|
||
|
||
bdflib puts data from the input stream into a buffer in chunks of
|
||
1024 bytes. The data itself gets then parsed line by line, simply
|
||
increasing the current pointer into the buffer; if the search for
|
||
the final newline character exceeds the buffer size, more data gets
|
||
read.
|
||
|
||
However, in case the current line's end is very near to the buffer
|
||
end, and the keyword to compare with is longer than the current
|
||
line's length, an out-of-bounds read might happen since `memcmp'
|
||
doesn't stop properly at the string end.
|
||
|
||
* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
|
||
stop at string ends.

Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
|
||
Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove
|
||
entries for Meetai Mayak and Sharada – the Unicode ranges were
|

incorrect (and nobody has complained about that), fonts are scarce
|
||
for those scripts, and the Indic auto-hinter support is rudimentary

anyways.

2013-12-30 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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

[ftrfork] Fix the face order difference between POSIX and Carbon.
|
||
|
||
The fragmented resources in Suitcase and .dfont should be reordered
|
||
when `POST' resource for Type1 is being restored, but reordering of
|
||
sfnt resources induces the different face order. Now the ordering
|
||
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.

2013-12-21 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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.
|
||
|
||
* devel/ftoption.h, include/config/ftoption.h

|
||

|
||

* include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
|
||
data.

[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.
|
||
|
||
* src/truetype/ttgload.c (TT_LOADER_SET_PP)
|
||
[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
|
||
`grayscale_hinting' flags as conditionals for the x position of TSB
|
||
and BSB.
|
||
|
||
2013-12-05 Werner Lemberg <wl@gnu.org>

[truetype] Fix phantom point handling.
|
||
|
||
This is a further improvement to the changes from 2013-11-06.
|
||
|
||
* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
|
||
are rounded horizontally, vertical ones are rounded vertically.
|
||
(TT_LOADER_SET_PP): The horizontal position of vertical phantom
|
||
points in pre-ClearType mode is zero, as shown in the OpenType

|
||
`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
|
||
smaller, and the `ttdebug' demo program has access to function
|
||
numbers without additional costs.
|
||
|
||
Fortunately, no changes to FontForge are necessary – this is the
|
||
only external TrueType debugger I know of, but others may exist and
|
||
should check the code accordingly.
|
||
|
||
* src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and

`Cur_End' with a pointer to the corresponding `TT_DefRecord'

for the announcement.
|
||
|

|
||
this structure only as a pointer through `FT_Get_Sfnt_Table', there
|
||
shouldn't be any ABI problems.

[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.

* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
|
||
|
||
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).

FT_Open_Face: Improve external stream handling.
|

If the font's `clazz->init_face' function wants to swap to new

|
||
|
||
[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.
|
||
|
||
* src/autofit/afblue.dat: New data file.
|

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.

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.
|
||
|
||
Example:
|
||
bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf
|
||
|
||
Before:
|
||
|
||

(FT_MulFix_x86_64): New function.

||
|
||
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
|
||
`ftbench' as follows on a Galaxy Nexus:

2013-05-23 Behdad Esfahbod <behdad@google.com>
|
||
|
||
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.
