-
- [otvalid] Fix a naming convention conflicting with ftvalid.
-
- Some prototypes in ftvalid.h use `valid' for the variables
- typed as FT_Validator. Their implementations in src/base/
- ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
-
- Some macros in otvcommn.h assume the exist of the variable
- `valid' typed as OTV_Validator in the caller.
-
- Mixing these two conventions cause invalid pointer conversion
- and unexpected SEGV in longjmp. To prevent it, all variables
- typed as OTV_Validator are renamed to `otvalid'.
-
- * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
- * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
- otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'

- [pcf] Fix Savannah bug #43774.
-
- Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'
- functions. Since the PCF format doesn't have an official

-
- [cff] Modify an FT_ASSERT.
-
- * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah
- bug #43661, the test font `...aspartam.otf' still triggers an

-
- [autofit] Better fix for conversion specifiers in debug messages.
-
- Using `%ld' for pointer differences causes warnings on 32bit
- platforms. The correct type would be (the relatively new) `%td',
- however, this is missing on some important platforms.
-
- This patch improves the change from 2014-11-28.
-
- * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
- pointer differences are always sufficiently small.
- (af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
- af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

- (get_sfnt_table): Updated.

-
- Previously, those elements were handled only for sections present in
- a `<Sections>' chapter element.

-
- [docmaker] Allow empty lines in `<Order>' blocks.
-
- Before this patch, the suggested order of entries stopped at the
- first empty line.
-
- Obviously, nobody noticed that this problem caused a much reduced
- set of links in the `Synopsis' sections; in particular, the
- `<Order>' blocks contain a lot of entries that wouldn't be listed
- otherwise...
-
- * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
- New function to iterate over all items.
- (DocSection::process): Use it.

-
- * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
-

- eliminating the hack with an empty, full-width `<td>' element
- inbetween.
-
- The change also enforces the same (smaller) size for all index and
- TOC links.

- [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
-
- Don't cast cmap init function pointers to an incompatible type.
-
- Without this patch, the number of parameters between declaration and
- the real signature differs. Calling such a function results in
- undefined behavior.
-
- ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
- 6.5.2.2 Function calls
- 9 If the function is defined with a type that is not
- compatible with the type (of the expression) pointed to by
- the expression that denotes the called function, the
- behavior is undefined.
-
- On certain platforms (c -> js with emscripten) this causes
- termination of execution or invalid calls because in the emscripten
- implementation, function pointers of different types are stored in
- different pointer arrays. Incorrect pointer type here results in
- indexing of an incorrect array.

- Before this patch, it was impossible to ever call DELTAP[123] in

-
- [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.
-

-
- [autofit] More coverage fixes for complex scripts.
-
- * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage

-
- [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'.
-
-2014-04-05 Werner Lemberg <address@hidden>
-
- [autofit] Improve scoring algorithm for identifying stems.
-
- Problem reported by Karsten Lücke <address@hidden>.
-
- 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.

-
- * docs/INSTALL.CROSS: Revised and updated.

-
- [cff] Fix Savannah bug #41697, part 2.
-
- * src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
- cf2_initGlobalRegionBuffer): It is possible for a charstring to call
- a subroutine if no subroutines exist. This is an error but should
- not trigger an assert. Split the assert to account for this.
-
-2014-02-28 Dave Arnold <address@hidden>
-
- [cff] Fix Savannah bug #41697, part 1.
-
- * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is

-
- [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.
-
-2014-02-17 suzuki toshiya <address@hidden>

- [autofit] Fix Indic scripts.
-

- that the covered ranges are the same: Bengali, Devanagari, Gujarati,
- 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.
-
- * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
- AF_CONFIG_OPTION_CJK.
-
- * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.

- AF_CONFIG_OPTION_CJK, to update.

- zones.
-
-2014-01-03 Werner Lemberg <address@hidden>
-
- [autofit] Fix handling of default coverages.

- auxiliary macros; use them to define styles for Cyrillic, Greek, and

- Since those digits are used in combination with ordinary letters, it
- makes no sense to handle them separately.
-
- * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
- `options' parameter to 4 bits.

-
- * src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.

-2013-12-30 Werner Lemberg <address@hidden>
-
- [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.
-

-
- [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.

-
- [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.

-2013-11-13 Werner Lemberg <address@hidden>
-
- 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...

- subdirectory.

-
-2013-11-01 Werner Lemberg <address@hidden>
-
- [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.

-
- * include/freetype/tttables.h (TT_OS2): Add fields
- `usLowerPointSize' and `usUpperPointSize'. Since FreeType returns

-
- [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.
-
- * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h
- (FT_MulFix_arm) [__GNUC__]: Support clang compiler.

-
-2013-10-03 Dave Arnold <address@hidden>
-
- * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
-
- 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.
-
-2013-10-02 Darrell Bellert <address@hidden>
-
- * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
-
-2013-10-02 Dave Arnold <address@hidden>
-
- * 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.
-
-2013-09-29 Dave Arnold <address@hidden>
-
- 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.

-
- Better tracing of loaded glyphs.
-
- Previously, the loading of a glyph was traced at level 4, if at all.
- With this change, all font loading routines emit a tracing message

-
- [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.
- * src/tools/afblue.pl: New Perl script for processing `afblue.dat'.

-
- 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:

-
- which defines two new SFNT tables, `CBDT' and `CBLC' (named and

- 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.

+
+2014-12-11 Werner Lemberg <address@hidden>
+
+ * builds/toplevel.mk (dist): Use older POSIX standard for `tar'.
+
+ Apparently, BSD tar isn't capable yet of handling POSIX-1.2001

+ [gxvalid] Fix a naming convention conflicting with ftvalid.
+
+ See previous changeset for otvalid.
+
+ * src/gxvalid/{gxvcommn.h, gxvmort.h, gxvmorx.h}: Replace
+ `valid' by `gxvalid'.
+ * src/gxvalid/{gxvbsln.c, gxvcommn.c, gxvfeat.c, gxvjust.c,

+ gxvmorx1.c, gxvmorx2.c, gxvmorx4.c, gxvmorx5.c, gxvopbd.c,

+ it is typed as GXV_Validator.
+
+2014-12-09 suzuki toshiya <address@hidden>
+
+ [otvalid] Fix a naming convention conflicting with ftvalid.
+
+ Some prototypes in ftvalid.h use `valid' for the variables
+ typed as FT_Validator. Their implementations in src/base/
+ ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
+
+ Some macros in otvcommn.h assume the exist of the variable
+ `valid' typed as OTV_Validator in the caller.
+
+ Mixing these two conventions cause invalid pointer conversion
+ and unexpected SEGV in longjmp. To prevent it, all variables
+ typed as OTV_Validator are renamed to `otvalid'.
+
+ * src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
+ * src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
+ otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'
+ if it is typed as OTV_Validator.
+
+2014-12-09 suzuki toshiya <address@hidden>
+
+ [ftvalid] Introduce FT_THROW() in FT_INVALID_XXX macros.
+
+ Original patch is designed by Werner Lemberg. Extra part
+ for otvalid and gxvalid are added by suzuki toshiya, see
+ discussion:

+
+2014-12-08 Werner Lemberg <address@hidden>
+
+ [pcf] Fix Savannah bug #43774.
+
+ Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'
+ functions. Since the PCF format doesn't have an official
+ specification, we have to exactly follow these functions' behaviour.
+
+ The problem was unveiled with a patch from 2014-11-06, fixing issue
+ #43547.
+
+ * src/pcf/pcfread.c (pcf_read_TOC): Don't check table size for last
+ element. Instead, assign real size.
+
+2014-12-07 Werner Lemberg <address@hidden>
+
+ Work around a bug in Borland's C++ compiler.
+
+ See
+
+ http://qc.embarcadero.com/wc/qcmain.aspx?d=118998

+
+ docs/CHANGES: Updated, formatted.
+
+2014-12-04 Dave Arnold <address@hidden>
+
+ [cff] Modify an FT_ASSERT.
+
+ * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah
+ bug #43661, the test font `...aspartam.otf' still triggers an
+ FT_ASSERT. Since hintmap still works with count==0, ...
+ (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to
+ suppress the assert.
+
+2014-12-04 Dave Arnold <address@hidden>
+
+ [cff] Fix Savannah bug #43661.
+
+ * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,

+ avoid reading past end of hintmask.
+
+2014-12-03 Werner Lemberg <address@hidden>
+
+ docs/CHANGES: Updated.
+
+2014-12-03 Werner Lemberg <address@hidden>
+
+ [autofit] Better fix for conversion specifiers in debug messages.
+
+ Using `%ld' for pointer differences causes warnings on 32bit
+ platforms. The correct type would be (the relatively new) `%td',
+ however, this is missing on some important platforms.
+
+ This patch improves the change from 2014-11-28.
+
+ * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
+ pointer differences are always sufficiently small.
+ (af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
+ af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
+
+2014-12-03 Werner Lemberg <address@hidden>
+
+ FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality.
+
+ All public FreeType enumeration and flag values are uppercase...
+
+ * include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards
+ compatilibity, retain the old values as macros.
+
+ * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c
+ (get_sfnt_table): Updated.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ * include/*: Improve structure of documentation.
+
+ . Add and update many `<Order>' tags.
+ . Apply various documentation fixes.
+ . Remove details to deprecated (or never implemented) data.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ [docmaker] Always handle `<Order>' section elements.
+
+ Previously, those elements were handled only for sections present in
+ a `<Sections>' chapter element.
+
+ * src/tools/docmaker/content.py (ContentProcessor::finish):
+ Implement it.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ [docmaker] Properly handle empty rows in Synopsis.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ ` ' for empty fields.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ [docmaker] Thinko.
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Emit `/empty/' string for first element also.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ [docmaker] Honour empty lines in `<Order>' section element.
+
+ This greatly improves the readability of the `Synopsis' links.
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ Insert string `/empty/' between items.
+
+ * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it
+ robust against nonexistent keys.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
+ empty <td> elements for `/empty/'.
+
+2014-12-02 Werner Lemberg <address@hidden>
+
+ [docmaker] Ensure Python 3 compatibility.
+
+ * src/tools/docmaker/content.py (ContentProcessor::set_section,
+ ContentProcessor::finish): Replace `has_key' function with `in'
+ keyword.
+
+ * src/tools/docmaker/formatter.py (Formatter::__init__): Replace
+ sorting function with a key generator.
+ (Formatter::add_identifier): Replace `has_key' function with `in'
+ keyword.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote):
+ Replace `has_key' function with `in' keyword.
+ (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use
+ integer division.
+ s/<>/>/.
+
+ * src/tools/docmaker/utils.py: Import `itertools'.
+ (index_sort): Replaced by...
+ (index_key): ... this new key generator (doing exactly the same).
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ [docmaker] Don't output a block multiple times.
+
+ This bug was hidden by not processing all lines of `<Order>' blocks.
+
+ * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter
+ out field names.
+
+2014-11-29 Werner Lemberg <address@hidden>

+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url):
+ Accept second, optional argument to specify a name.
+ (HtmlFormatter::html_source_quote): Link to field ID if possible.
+ (HtmlFormatter::print_html_field_list): Emit `id' attribute.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ [docmaker] Allow empty lines in `<Order>' blocks.
+
+ Before this patch, the suggested order of entries stopped at the
+ first empty line.
+
+ Obviously, nobody noticed that this problem caused a much reduced
+ set of links in the `Synopsis' sections; in particular, the
+ `<Order>' blocks contain a lot of entries that wouldn't be listed
+ otherwise...
+
+ * src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+ New function to iterate over all items.
+ (DocSection::process): Use it.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ * src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp.
+
+ After the single asterisk there must be no other immediately following
+ asterisk.

+
+ * src/tools/docmaker/tohtml.py: Introduce a new table class `toc',
+ together with proper CSS.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ [docmaker] Provide higher-level markup and simplify HTML.
+
+ * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'
+ elements, use CSS descendants (of class `section') to format the
+ data.
+
+ Also remove reduntant <p> and <br> elements, replacing them with
+ proper CSS.
+
+ Globally reduce page width to 75%.
+
+ (block_header): Rename <div> class to `section'.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ [docmaker] Add `top' links after blocks.
+
+ * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ * src/tools/docmaker/tohtml.py: Improve CSS for fields.
+
+ Make fields align horizontally relative to full line width.
+
+2014-11-29 Werner Lemberg <address@hidden>
+
+ * src/tools/docmaker/tohtml.py: Fix index and TOC templates.
+
+ This thinko was introduced 2014-11-27.
+
+2014-11-28 Werner Lemberg <address@hidden>
+
+ [docmaker] Format field lists with CSS.
+
+ This also simplifies the inserted HTML code.
+
+ * src/tools/docmaker/tohtml.py
+ (HtmlFormatter::print_html_field_list): Do it.
+
+2014-11-28 suzuki toshiya <address@hidden>
+
+ Fix compiler warning to the comparison between signed and
+ unsigned variable.
+
+ * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison
+ between `ypos + ysize' and FT_INT_{MAX,MIN}.
+
+2014-11-28 Werner Lemberg <address@hidden>
+
+ [docmaker] Replace empty `<td>' with CSS.
+
+ * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do
+ it.
+
+2014-11-28 Werner Lemberg <address@hidden>
+
+ [docmaker] Replace some `<table>' tags with `<h4>' and `<div>'.
+
+ * src/tools/docmaker/tohtml.py (marker_*): Use `<h4>'.
+ (source_*): Use `<div>'.
+ (HtmlFormatter::block_enter): s/<h4>/<h3>/.
+
+2014-11-28 suzuki toshiya <address@hidden>
+
+ Fix compiler warning to conversion specifiers in debug messages.
+
+ * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length
+ modifier to dump long integers.
+ (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.
+
+2014-11-27 Werner Lemberg <address@hidden>

+
+2014-11-27 Werner Lemberg <address@hidden>
+
+ * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
+
+ For `Index' and `TOC' links, we now simply use the `text-align' CSS
+ property of `<td>' to enforce flush-left and flush-right,
+ eliminating the hack with an empty, full-width `<td>' element
+ inbetween.
+
+ The change also enforces the same (smaller) size for all index and
+ TOC links.
+
+2014-11-27 suzuki toshiya <address@hidden>
+
+ * src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(),
+ cf2font.c could not find it under `make multi' build.
+
+2014-11-27 suzuki toshiya <address@hidden>
+
+ * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove
+ unrequired negative value check for `width' and `height'.
+
+2014-11-27 Werner Lemberg <address@hidden>

+
+ Replace some `<table>' tags with `<div>' to simplify structure.
+
+ Move `bgcolor' attribute to CSS.
+
+ Replace most `width' attributes with CSS. The remaining instances

+ in a later patch.
+
+2014-11-27 Werner Lemberg <address@hidden>
+
+ * src/tools/docmaker/tohtml.py: Replace <font> with CSS.

+ [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
+
+ Don't cast cmap init function pointers to an incompatible type.
+
+ Without this patch, the number of parameters between declaration and

+ undefined behavior.
+
+ ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
+ 6.5.2.2 Function calls
+ 9 If the function is defined with a type that is not
+ compatible with the type (of the expression) pointed to by
+ the expression that denotes the called function, the
+ behavior is undefined.
+
+ On certain platforms (c -> js with emscripten) this causes
+ termination of execution or invalid calls because in the emscripten
+ implementation, function pointers of different types are stored in
+ different pointer arrays. Incorrect pointer type here results in
+ indexing of an incorrect array.

+ [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.

+ syntax to have both reference and overshoot characters in a single

+ 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

+
+ [autofit] Improve scoring algorithm for identifying stems.
+
+ Problem reported by Karsten Lücke <address@hidden>.
+
+ 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.

+
+ [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.

+ [autofit] Fix Indic scripts.
+
+ Split the single, incorrect Indic entry into separate scripts so
+ that the covered ranges are the same: Bengali, Devanagari, Gujarati,
+ 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.
+
+ * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
+ AF_CONFIG_OPTION_CJK.
+
+ * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
+ Use it, together with AF_CONFIG_OPTION_INDIC and
+ AF_CONFIG_OPTION_CJK, to update.
+
+ * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
+ [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.

+
+ [autofit] Don't combine multiple features into one set.
+
+ Combining them, as originally envisioned, would lead to much more

+
+ [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.

+
+ [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.

+
+ 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.
+

+ [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

+ However, in GCC, due to some legacy compatibility considerations,

+
+ * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
+
+ 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.
+
+2013-10-02 Darrell Bellert <address@hidden>

+
+2013-10-02 Dave Arnold <address@hidden>
+
+ * 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.
+
+2013-09-29 Dave Arnold <address@hidden>
+
+ 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.

+
+ [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.

+2013-07-16 David Turner <address@hidden>
+
+ 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:
