+2013-12-07 Werner Lemberg <wl@gnu.org>
+
+ [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>
+
+ * builds/freetype.mk (FT_CC): Removed. Unused.
+
+2013-12-04 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Fix handling of embedded bitmap strikes.
+
+ This corrects the commit from 2013-11-21. Problem reported by
+ Andrey Panov <panov@canopus.iacp.dvo.ru>.
+
+ * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Fix logic to
+ detect excessive bytes for bit-aligned bitmaps.
+
+2013-12-03 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Remove dead code.
+
+ Reported by Nigel Tao <nigeltao@golang.org>.
+
+ * include/internal/tttypes.h (TT_LoaderRec): Remove unused
+ `preserve_pps' field.
+ * src/truetype/ttgload.c (TT_Hint_Glyph): Updated.
+
+2013-12-03 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
+ specification.
+
+2013-12-02 Werner Lemberg <wl@gnu.org>
+
+ [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.
+
+2013-11-27 Werner Lemberg <wl@gnu.org>
+
+ [autofit] Fix use of dumping functions in `ftgrid' demo program.
+
+ * src/autofit/afhints.c (AF_DUMP) [FT_DEBUG_AUTOFIT]: New macro.

+ handle output to stdout.
+ Use AF_DUMP.

+
+2013-11-21 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Improve handling of buggy embedded bitmap strikes.
+
+ We are now able to successfully load `AppleMyoungJo.ttf'.

+ format.
+
+2013-11-20 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Don't trust `maxp's `maxSizeOfInstructions'.
+

+
+ http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html

+ for details.

+ tables also for setting `autohint'.
+
+ * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from

+ `maxSizeOfInstructions'.
+
+2013-11-16 Werner Lemberg <wl@gnu.org>
+
+ [sfnt] Fix `OS/2' table version 5 support.
+
+ We now follow the `official' announcement from Microsoft (on the
+ OpenType mailing list, which unfortunately hasn't a public archive).
+
+ * include/freetype/tttables.h (TT_OS2):
+ s/usLowerPointSize/usLowerOpticalPointSize/,
+ s/usUpperPointSize/usUpperOpticalPointSize/.
+
+ * src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct

+
+2013-11-13 Werner Lemberg <wl@gnu.org>
+
+ * builds/unix/ft2unix.h: Remove. No longer necessary.
+
+ * builds/unix/install.mk (install): Updated.
+
+2013-11-13 Werner Lemberg <wl@gnu.org>
+
+ 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.
+
+ * builds/amiga/include/freetype/*: Move up to...
+ * builds/amiga/include/*: ... this directory.
+
+ */*: Essentially do `s@/freetype/@/@' where appropriate.
+
+ * CMakeList.txt: Simplify.
+ * builds/unix/freetype-config.in, builds/unix/freetype2.in: For
+ `--cflags', return a single directory.
+ * builds/unix/install.mk (install): No longer try to remove `cache'
+ and `internal' subdirectories; instead, remove the `freetype'
+ subdirectory.
+
+2013-11-12 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix last `truetype' commit.
+
+ * src/truetype/ttgload.c (tt_get_metrics): Preserve stream position.

+
+2013-11-06 Werner Lemberg <wl@gnu.org>

+ [truetype] Fix handling of phantom points in composite glyphs.
+ Problem reported by Nigel Tao <nigeltao@golang.org>.
+
+ This is a follow-up commit to the previous one.
+

+
+2013-11-06 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Improve emulation of vertical metrics.
+
+ This commit also improves the start values of vertical phantom
+ points. Kudos to Greg Hitchcock for help.
+
+ * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass
+ `yMax' value. Replace code with fixed Microsoft definition.
+ (tt_get_metrics): Updated.
+ (TT_LOADER_SET_PP): Add explanation how to initialize phantom
+ points, taken from both the OpenType specification and private
+ communication with Greg (which will eventually be added to the
+ standard).
+ Fix horizontal position of `pp3' and `pp4'.
+
+ * src/truetype/ttgload.h: Updated.
+

+

+
+2013-11-01 Werner Lemberg <wl@gnu.org>
+
+ [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'
+ structure.
+
+ * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF,

+
+ See
+
+ http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism
+
+ for the announcement.
+
+ * include/freetype/tttables.h (TT_OS2): Add fields
+ `usLowerPointSize' and `usUpperPointSize'. Since FreeType returns
+ this structure only as a pointer through `FT_Get_Sfnt_Table', there
+ shouldn't be any ABI problems.
+
+ * src/sfnt/ttload.c (tt_face_load_os2): Implement it.
+
+ * docs/CHANGES: Updated.
+
+2013-10-24 Werner Lemberg <wl@gnu.org>

+ [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,

+
+2013-10-03 Dave Arnold <darnold@adobe.com>
+
+ * 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 <darrell.bellert@hl.konicaminolta.us>
+
+ * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
+
+2013-10-02 Dave Arnold <darnold@adobe.com>
+
+ * 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 <darnold@adobe.com>
+
+ 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.

+
+ Implement support for WOFF containers.
+
+ We simply synthesize a SFNT from the WOFF, create a memory stream
+ for the new data, and load the SFNT as usual.
+
+ Does NOT add any API to access WOFF metadata or private blocks.

+
+ 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.
+
+ 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

+2013-08-25 Werner Lemberg <wl@gnu.org>
+
+ [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'.

+ (FT_MulFix_x86_64): New function.
+
+2013-07-16 David Turner <digit@google.com>
+
+ 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:
+
+ Before (us/op) After (us/op)
+
+ - loading Arial.ttf glyphs at 14 ppem [1]

+ *
+ * @description:
+ * While FreeType's CFF driver doesn't expose API functions by itself,
+ * it is possible to control its behaviour with @FT_Property_Set and
+ * @FT_Property_Get. The list below gives the available properties
+ * together with the necessary macros and structures.
+ *
+ * The CFF driver's module name is `cff'.
+ *
+ * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
+ *
+ * The rasterizer is positioning horizontal features (e.g., ascender
+ * height & x-height, or crossbars) on the pixel grid and minimizing the
+ * amount of antialiasing applied to them, while placing vertical
+ * features (vertical stems) on the pixel grid without hinting, thus
+ * representing the stem position and weight accurately. Sometimes the
+ * vertical stems may be only partially black. In this context,
+ * `antialiasing' means that stems are not positioned exactly on pixel
+ * borders, causing a fuzzy appearance.
+ *
+ * There are two principles behind this approach.
+ *
+ * 1) No hinting in the horizontal direction: Unlike `superhinted'
+ * TrueType, which changes glyph widths to accommodate regular
+ * inter-glyph spacing, Adobe's approach is `faithful to the design' in
+ * representing both the glyph width and the inter-glyph spacing
+ * designed for the font. This makes the screen display as close as it
+ * can be to the result one would get with infinite resolution, while
+ * preserving what is considered the key characteristics of each glyph.
+ * Note that the distances between unhinted and grid-fitted positions at
+ * small sizes are comparable to kerning values and thus would be
+ * noticeable (and distracting) while reading if hinting were applied.
+ *
+ * One of the reasons to not hint horizontally is antialiasing for LCD
+ * screens: The pixel geometry of modern displays supplies three
+ * vertical sub-pixels as the eye moves horizontally across each visible
+ * pixel. On devices where we can be certain this characteristic is
+ * present a rasterizer can take advantage of the sub-pixels to add
+ * increments of weight. In Western writing systems this turns out to
+ * be the more critical direction anyway; the weights and spacing of
+ * vertical stems (see above) are central to Armenian, Cyrillic, Greek,
+ * and Latin type designs. Even when the rasterizer uses greyscale
+ * antialiasing instead of color (a necessary compromise when one
+ * doesn't know the screen characteristics), the unhinted vertical
+ * features preserve the design's weight and spacing much better than
+ * aliased type would.
+ *
+ * 2) Aligment in the vertical direction: Weights and spacing along the
+ * y~axis are less critical; what is much more important is the visual
+ * alignment of related features (like cap-height and x-height). The
+ * sense of alignment for these is enhanced by the sharpness of grid-fit
+ * edges, while the cruder vertical resolution (full pixels instead of
+ * 1/3 pixels) is less of a problem.
+ *
+ * On the technical side, horizontal alignment zones for ascender,
+ * x-height, and other important height values (traditionally called
+ * `blue zones') as defined in the font are positioned independently,
+ * each being rounded to the nearest pixel edge, taking care of
+ * overshoot suppression at small sizes, stem darkening, and scaling.
+ *
+ * Hstems (this is, hint values defined in the font to help align
+ * horizontal features) that fall within a blue zone are said to be
+ * `captured' and are aligned to that zone. Uncaptured stems are moved
+ * in one of four ways, top edge up or down, bottom edge up or down.
+ * Unless there are conflicting hstems, the smallest movement is taken
+ * to minimize distortion.
