+2015-06-06 Ashish Azad <ashish.azad@samsung.com>
+
+ Fix Savannah bug #45260.
+
+ * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo.
+
+2015-06-03 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix memory leak.
+
+ Problem reported by Grissiom <chaos.proton@gmail.com>; in
+
+ http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html
+
+ there is an example code to trigger the bug.
+
+ * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'
+ data before allocating again. Bug most probably introduced four
+ years ago in version 2.4.3.
+
+2015-06-02 Werner Lemberg <wl@gnu.org>
+
+ [raster] Add more tracing.
+
+ * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define.
+ (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span,
+ Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
+
+2015-06-01 Werner Lemberg <wl@gnu.org>
+
+ [truetype] While tracing opcodes, show code position and stack.
+
+ * src/truetype/ttinterp.c: Change all existing TRACE7 calls to
+ TRACE6.
+ (opcode_name): Add string lengths.
+ (TT_RunIns): Implement display of code position and stack.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make private point numbers work correctly.
+
+ This is completely missing in Apple's documentation: If a `gvar'
+ tuple uses private point numbers (this is, deltas are specified for
+ some points only), the uncovered points must be interpolated for
+ this tuple similar to the IUP bytecode instruction. Examples that
+ need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+ * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+ tt_handle_deltas): New functions.
+ (TT_Vary_Get_Glyph_Deltas): Renamed to...
+ (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
+ points and does no longer return an array of deltas.
+ Add tracing information.
+ Call `tt_handle_deltas' to interpolate missing deltas.
+ Also fix a minor memory leak in case of error.
+
+ * src/truetype/ttgxvar.h: Updated.
+
+ * src/truetype/ttgload.c (TT_Process_Simple_Glyph,
+ load_truetype_glyph): Updated.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] In GX, make intermediate tuplets work at extrema.
+
+ * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
+
+2015-05-31 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Add tracing information to GX code.
+
+ * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
+ ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
+ TT_Set_Var_Design, tt_face_vary_cvt): Do it.
+
+2015-05-28 Werner Lemberg <wl@gnu.org>
+
+ * src/tools/apinames.c (names_dump): Fix invalid reference.
+
+ Problem reported by Guzman Mosqueda, Jose R
+ <jose.r.guzman.mosqueda@intel.com>.
+
+2015-05-24 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix commit from 2015-05-22.
+
+ * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
+ with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.
+
+ Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Fix return values of GETINFO bytecode instruction.
+
+ * src/truetype/ttinterp.h (TT_ExecContextRec): New fields
+ `vertical_lcd' and `gray_cleartype'.
+
+ * src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
+ Change `symmetrical smoothing' to TRUE, since FreeType produces
+ exactly this.
+
+ * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
+ values for symmetrical smoothing, namely 11/18.
+ Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
+ (12/19).
+
+2015-05-23 Werner Lemberg <wl@gnu.org>
+
+ [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.
+
+ * docs/CHANGES: Document it.
+
+2015-05-20 Werner Lemberg <wl@gnu.org>
+
+ [truetype] Minor.
+
+ * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
+ argument.
+
+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).
+
+2015-05-12 Chris Liddell <chris.liddell@artifex.com>
+
+ [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).
+
+2015-04-29 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [autofit] Speed up IUP.
+
+ * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
+ the same position from true interpolation, use `scale' to reduce
+ divisions.
+
+2015-04-28 Werner Lemberg <wl@gnu.org>
+
+ [cff] Use `name' table for PS name if we have a SFNT-CFF.
+
+ This follows the OpenType 1.7 specification. See
+
+ http://tug.org/pipermail/tex-live/2015-April/036634.html
+
+ for a discussion.
+
+ * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we
+ have an SFNT.
+
+2015-04-27 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [truetype] Speed up IUP.
+
+ * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial
+ snapping to the same position from true interpolation.
+

+ [autofit] By default, enable warping code but switch off warping.
+
+ Suggested by Behdad.
+
+ * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER.
+
+ * src/autofit/afmodule.c (af_autofitter_init): Initialize `warping'

+
+ * docs/CHANGES: Updated.
+
+2015-04-21 Werner Lemberg <wl@gnu.org>

+
+2015-04-10 Werner Lemberg <wl@gnu.org>
+
+ [cff] Update advance width handling to OpenType 1.7.
+
+ Problem reported by Behdad.
+
+ * src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case
+ separately.
+
+ * src/cff/cffgload.c (cff_slot_load): Use advance width and side

+
+2015-03-21 Alexei Podtelezhnikov <apodtele@gmail.com>
+
+ [base] Optimize `FT_Angle_Diff'.

+ of angle values, so that the remainder is not really necessary.
+
+ * src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder.

+
+ [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).
+
+2015-01-17 Werner Lemberg <wl@gnu.org>
+
+ Add some tools to handle yearly copyright notice updates.

+
+ * src/tools/update-copyright-year: New Perl script.
+ * src/tools/update-copyright: New shell script that calls

+ Avoids multiple mallocs per typical glyphs.

+ cached singleton.
+

+ [autofit] Reuse slot glyph loader.
+
+ No need to create a new glyph loader; we can reuse the one from

+ (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

+
+ [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.
+
+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [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>
+
+ [base] Don't initialize unused `driver->glyph_loader'.
+
+ * src/base/ftobjs.c (Destroy_Driver): Don't call

+
+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
+ (FT_Outline_Render): Don't call `FT_Set_Renderer'.

+2015-01-14 Behdad Esfahbod <behdad@behdad.org>
+
+ [raster] Allocate render pool for mono rasterizer on the stack.
+
+ Instead of using the `render_pool' member of `FT_Library' that is
+ provided down to the rasterizer, completely ignore that and allocate
+ needed objects on the stack instead.
+
+ With this patch, rasterizing glyphs from different faces from
+ different threads doesn't crash in the monochrome rasterizer.
+
+ * src/raster/ftraster.c (black_TRaster): Remove `buffer',

+
+ [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+ It was off by default and couldn't be turned on at runtime. And the
+ smooth rasterizer superceded it over ten years ago. No point in

+ with FreeType 1.
+

+
+ [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.
+
