Werner Lemberg c9d9947c68 [autofit] Fix interface of `af_get_char_index'.
* src/autofit/hbshim.c (af_get_char_index): Return error value.
Add argument for y offset (to be used in a yet-to-come patch).

Werner Lemberg 44aa7e0af5 [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'.

* src/autofit/aftypes.h: Updated.
* src/autofit/hbshim.c: Updated.

Werner Lemberg 00a7b51fab Minor. 2013-12-27 19:18:49 +01:00
suzuki toshiya e2d2b1544f [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 FreeType2 without
Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

Werner Lemberg c7b55a3473 Split off ChangeLog.24. 2013-12-23 16:42:03 +01:00
Werner Lemberg 1924134710 Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
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

Werner Lemberg fae3820764 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.

* include/freetype/*: Move up to...
* include/*: ... this directory.

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.
2013-10-02 11:04:06 +02:00
Dave Arnold 3a2cb0f881 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.
