-
- We no longer `pollute' the namespace of possible header file names;

- [truetype] Minor.
-
- * src/truetype/ttinterp.h (TT_ExecContext):
- s/subpixel/subpixel_hinting.

- * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
-
-2015-05-22 Werner Lemberg <wl@gnu.org>
-
- [truetype] Support selector index 3 of the INSTCTRL instruction.
-
- This flag activates `native ClearType hinting', disabling backwards
- compatibility mode as described in Greg Hitchcocks whitepaper. In
- other words, it enables unrestricted functionality of all TrueType
- instructions in ClearType.
-
- * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
- unconditionally.
- (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
- `GS.instruct_control' is active.
-
- * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
- (Ins_GETINFO): Updated.

-2015-05-17 Werner Lemberg <wl@gnu.org>
-
- [truetype] Fix loading of composite glyphs.
-
- * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
- ARGS_ARE_XY_VALUES flag is not set, handle argument values as
- unsigned. I trust `ttx' (which has exactly such code) that it does
- the right thing here...
-
- The reason that noone has ever noticed this bug is probably the fact
- that point-aligned subglyphs are rare, as are subglyphs with a
- number of points in the range [128;255], which is quite large (or
- even in the range [32768;65535], which is extremely unlikely).

-
- [cff] Make the `*curveto' operators more tolerant.
-
- * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
- `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
- pulling values off the stack until the stack is exhausted.
- Implicitly the stack must be a multiple (or for subtly different
- behaviour) a multiple plus a specific number of extra values deep.
- If that's not the case, enforce it (as the old code did).
-
-2015-05-12 Chris Liddell <chris.liddell@artifex.com>
-
- [cff] fix incremental interface with new cff code.
-
- * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
- interface to retrieve glyph data for a SEAC, it be left to the
- incremental interface callback to apply the encoding to raw
- character index (as it was in the previous code).

- [raster] Fix Savannah bug #44022.
-
- Add fallback for glyphs with degenerate bounding boxes.
-
- If a glyph has only one very narrow feature, the bbox can end up
- with either the width or height of the bbox being 0, in which case
- no raster memory is allocated and no attempt is made to render the
- glyph. This is less than ideal when the drop-out compensation in
- the rendering code would actually result in the glyph being
- rendered.
-
- This problem can be observed with the `I' glyph (gid 47) in the
- Autodesk RomanS TrueType font.
-
- * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
- dimension is zero to explicitly round up/down (instead of simply
- round).

-
- No need to create a new glyph loader; we can reuse the one from

- way originally, but new code looks sound and correct to me, and
- avoids lots of allocations.
-
- * src/autofit/afloader.c (af_loader_init): Change return type to

- Don't call `FT_GlyphLoader_New'.
- (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [autofit] Remove (unused) support for composite glyphs.
-
- We never have to deal with composite glyphs in the autohinter, as
- those will be loaded into FORMAT_OUTLINE by the recursed
- `FT_Load_Glyph' function.
-
- In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
- FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
- FT_LOAD_NO_HINTING:
-
- /* resolve load flags dependencies */
-
- if ( load_flags & FT_LOAD_NO_RECURSE )
- load_flags |= FT_LOAD_NO_SCALE |
- FT_LOAD_IGNORE_TRANSFORM;
-
- if ( load_flags & FT_LOAD_NO_SCALE )
- {
- load_flags |= FT_LOAD_NO_HINTING |
- FT_LOAD_NO_BITMAP;
-
- load_flags &= ~FT_LOAD_RENDER;
- }
-
- and as such the auto-hinter is never called. Thus, the recursion in
- `af_loader_load_g' never actually happens. So remove the depth
- counter as well.
-
- * src/autofit/afloader.c (af_loader_load_g): Remove `depth'
- parameter.
- <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
- (af_loader_load_glyph): Updated.

-
- [raster] Fix uninitialized memory access.
-
- Apparently `ras.cProfile' might be uninitialized. This will be the
- case if `ras.top == ras.cProfile->offset', as can be seen in
- `End_Profile'. The overshoot code introduced in a change `Fix B/W
- rasterization of subglyphs with different drop-out modes.' (from
- 2009-06-18) violated this, accessing `ras.cProfile->flags'
- unconditionally just before calling `End_Profile' (which then
- detected that `cProfile' is uninitialized and didn't touch it).
-
- This was harmless, and was not detected by valgrind before because
- the objects were allocated on the `raster_pool', which was always
- initialized. With recent change to allocate raster buffers on the
- stack, valgrind now reported this invalid access.
-
- * src/raster/ftraster.c (Convert_Glyph): Don't access an
- uninitialized `cProfile'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [smooth] Fix uninitialized memory access.
-
- Looks like `ras.span_y' could always be used without initialization.
- This was never detected by valgrind before because the library-wide
- `raster_pool' was used for the worker object and `raster_pool' was
- originally zero'ed. But subsequent reuses of it were using `span_y'
- uninitialized. With the recent change to not use `render_pool' and
- allocate worker and buffer on the stack, valgrind now detects this
- uninitialized access.
-
- * src/smooth/ftgrays.c (gray_raster_render): Initialize
- `ras.span_y'.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>

-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [base] Don't allocate `library->raster_pool' anymore.
-
- It's unused after the following commits:
-
- [raster] Allocate render pool for mono rasterizer on the stack.
- [raster] Remove 5-level gray AA mode from monochrome rasterizer.
-
- The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
- serve, which is, to adjust the pool size. But the pool is now
- allocated on the stack on demand.
-
- * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
-
-2015-01-14 Behdad Esfahbod <behdad@behdad.org>
-
- [base] Do not reorder library->renderers upon use.
-
- Instead of keeping `library->renderers' in a MRU order, just leave
- it as-is. The MRU machinery wasn't thread-safe.
-
- With this patch, rasterizing glyphs from different faces from
- different threads doesn't fail choosing rasterizer
- (FT_Err_Cannot_Render_Glyph).
-
- Easiest to see that crash was to add a `printf' (or otherwise let
- thread yield in FT_Throw with debugging enabled).
-
- * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c

- [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
-
- Previously the code had stipulation for using a per-TT_Size exec
- context if `size->debug' was true. But there was no way that
- `size->debug' could *ever* be true. As such, the code was always
- using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
- This was, clearly, not threadsafe.
-
- With this patch, loading glyphs from different faces from different
- threads doesn't crash in the bytecode loader code.

- [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'.

-
- [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.

-
- `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',

- * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.
-
- Before this patch, it was impossible to ever call DELTAP[123] in
- subpixel hinting mode as described in the ClearType whitepaper; it
- only worked if in `compatibility mode'. However, compatibility mode
- essentially disables SHPIX, completely ruining hinting of
- ttfautohint output, for example.
-
- We now follow the whitepaper more closely so that DELTAP[123]
- instructions for touched points in the non-subpixel direction are
- executed.

-
- [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.

- 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.
+ [smooth] Faster alternative line renderer.
- 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.
+ This implementation renders the entire line segment at once without
+ subdividing it into scanlines. The main speed improvement comes from
+ reducing the number of divisions to just two per line segment, which
+ is a bare minimum to calculate cell coverage in a smooth rasterizer.
+ Notably, the progression from cell to cell does not itself require any
+ divisions at all. The speed improvement is more noticeable at larger
+ sizes.
- 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.
+ * src/smooth/ftgrays.c (gray_render_line): New implementation.
- This generally improves the auto-hinter's rendering results.

-
- [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.

- Simplify header file hierarchy.
+ * src/bdf/bdflib.c (_bdf_parse_start): Simplify bpp parsing.
- This large patch changes the header file directory layout from

- level. Since the file `ft2build.h' is also located in `include'
- (and it stays there even after installation), all FreeType header

- Fix Savannah bug #39295.
+ for a discussion.
- 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.
+ * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we
+ have an SFNT.
- 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.
+2015-04-27 Alexei Podtelezhnikov <apodtele@gmail.com>
- 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.
+ [truetype] Speed up IUP.
- Some glyphs in the bug report font (TexGyreHeros-Regular) that show
- the change are:
+ * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial
+ snapping to the same position from true interpolation.
- 25ppem S (98)
- 24ppem eight (52)
- 25.5ppem p (85)
+2015-04-21 Werner Lemberg <wl@gnu.org>
- 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.
+ [autofit] By default, enable warping code but switch off warping.
- 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).
+ Suggested by Behdad.
- * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
- to indicate that we synthesize a closepath line.
+ * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER.
- * 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

- [autofit] Introduce data file for blue strings.
+2015-03-05 Alexei Podtelezhnikov <apodtele@gmail.com>
- 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:
+ * src/base/ftstroke.c: Simplify.
- . The data file should be easily readable. We use UTF-8 encoding
- which then gets converted to single bytes.
+2015-03-04 Werner Lemberg <wl@gnu.org>
- . 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.
+ [truetype] Some fixes and code refactoring in `ttgxvar.c'.
- This commit only adds files without changing any functionality.
+ * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix return value
+ of `point_cnt' if two bytes are read.

- When building for ARMv7 with thumb2 instructions, the optimized

- in Thumb-2 mode, though.
+ [truetype] Finish compiler warning fixes for signedness issues.
- - 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

+ Add fallback for glyphs with degenerate bounding boxes.
-2013-06-12 Werner Lemberg <wl@gnu.org>
+ If a glyph has only one very narrow feature, the bbox can end up
+ with either the width or height of the bbox being 0, in which case
+ no raster memory is allocated and no attempt is made to render the
+ glyph. This is less than ideal when the drop-out compensation in
+ the rendering code would actually result in the glyph being
+ rendered.
- More compiler warning fixes.
+ This problem can be observed with the `I' glyph (gid 47) in the
+ Autodesk RomanS TrueType font.
