2015-10-06 Alexei Podtelezhnikov <[email protected]>
[smooth] Faster alternative line renderer.
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.
* src/smooth/ftgrays.c (gray_render_line): New implementation.
2015-10-06 Werner Lemberg <[email protected]>

the buffer `sfnt_ps' if an error caused before calling
open_face_from_buffer().
(Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if

2015-09-23 Werner Lemberg <[email protected]>
[sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values. This commit tries to improve that.
* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
tt_cmap12_char_map_binary, tt_cmap13_next,
tt_cmap13_char_map_binary): Reject glyph indices larger than or
equal to the number of glyphs.
2015-09-23 Werner Lemberg <[email protected]>

* src/base/ftbase.h (FT_MAC_RFORK_MAX_LEN): Maximum length of the
resource fork for Mac OS. Resource forks larger than 16 MB can be
written but can't be handled correctly, at least in Carbon routine.
See https://support.microsoft.com/en-us/kb/130437.
* src/base/ftobjs.c (Mac_Read_POST_Resource): No need to use `0x'
prefix for `%p' formatter.

2015-09-19 Werner Lemberg <[email protected]>
[sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.
- It incorrectly assumed that valid tables are always at the
beginning. As a consequence, some valid tables after invalid
entries (which are ignored) were never seen.
- Duplicate table entries (this is, having the same tag) were not
rejected.
- The number of valid tables was sometimes too large, leading to
access of invalid tables.
* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.
Reject duplicate tables and adjust number of valid tables

2015-09-04 Werner Lemberg <[email protected]>
[autofit] Redesign code ranges (1/2).
This patch introduces auxiliary code ranges that identify no-base
characters; they refer to glyphs of a script that should be hinted
without alignments to blue zones (mostly diacritics).
It also splits off ranges for fallback scripts that handle subscript
and superscript characters not covered by OpenType features. For
example, this greatly helps improve the hinting of various phonetic
alphabets, which contain a large amount characters that look like
superscript glyphs.
Finally, code ranges are updated to Unicode 8.0, and enclosed
characters are removed in general since they normally look better if
they stay unhinted.
* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
8.0.
Split off superscript-like and subscript-like glyphs into...
(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
of the corresponding character ranges.

[type42] Fix glyph access.
This is a severe bug: We've missed one level of indirection, as
described in the Type 42 specification. As a result, ftview
sometimes showed incorrect glyphs for given glyph names, and even
displayed `error 0x0006' (invalid argument!) in case the number of
glyph indices differed between the Type 42 font and the embedded
TTF.
Apparently, noone ever noticed it; this shows how much Type 42 fonts
are in use...

to embedded TTF's glyph index.

Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include). After this commit, only `ft2build.h' stays in
the compiler's include path.
No visible changes for the user who follows the standard FreeType
header inclusion rules.
* include/*: Move to ...

[truetype] Fix memory leak.
Problem reported by Grissiom <[email protected]>; 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'

(TT_RunIns): Implement display of code position and stack.
2015-05-31 Werner Lemberg <[email protected]>
[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.

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

[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.

[truetype] Minor.
* src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
argument.
2015-05-17 Werner Lemberg <[email protected]>
[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 <[email protected]>
[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 <[email protected]>
[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).

is a better choice for `hash' to hold a pointer than `FT_PtrDist'
(a.k.a. `ptrdiff_t'), especially since the latter is signed,
causing zillions of signedness warnings. [Note that `hash' was of
type `FT_UInt32' before the change to `FT_PtrDist'.]

[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 <[email protected]>
Add some tools to handle yearly copyright notice updates.
We are now following the GNU guidelines: A new release automatically
means that the copyright year of all affected files gets updated; it
is no longer used to track years of modification changes.

[autofit] Add embedded array of segments and edges.
Avoids multiple mallocs per typical glyphs.
With this and recent changes to avoid mallocs, the thread-safe
stack-based loader is now as fast as the previous model that had one
cached singleton.
* src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):
New macros.
(AF_AxisHintsRec): Add two arrays for segments and edges.
* src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate
data if number of segments exceeds given threshold value.
(af_axis_hints_new_edge): Only allocate data if number of edges
exceeds given threshold value.

parameter instead of `FT_Memory'.
(af_loader_done): Directly reset `load_hints'.

2015-01-14 Behdad Esfahbod <[email protected]>
[autofit] Reuse slot glyph loader.
No need to create a new glyph loader; we can reuse the one from
`slot->internal->loader'. It's hard to tell why it was written that
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
`void'.
Don't call `FT_GlyphLoader_New'.
(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
(af_loader_load_g): Update code to use `internal->loader', which
doesn't need copying of data.
* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
Update prototype.
* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
2015-01-14 Behdad Esfahbod <[email protected]>
[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 <[email protected]>
[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'.

[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'.

[base] Don't initialize unused `driver->glyph_loader'.
* src/base/ftobjs.c (Destroy_Driver): Don't call
`FT_GlyphLoader_Done'.
(FT_Add_Module): Don't call `FT_GlyphLoader_New'.

[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.

[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 <[email protected]>
[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',
`buffer_size', and `worker' members.
(ft_black_render): Create `buffer' locally.
(ft_black_reset): Updated.
2015-01-14 Behdad Esfahbod <[email protected]>
[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
keeping. Comments suggested that it was there for compatibility
with FreeType 1.
550 lines down.
* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
RASTER_GRAY_LINES): Remove macros and all associated code.
(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
(black_TRaster): Remove `grays' and `gray_width'.
(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,
ft_black_render): Updated.
* src/raster/ftrend1.c (ft_raster1_render): Simplify code.
(ft_raster5_renderer_class): Removed.

[smooth] Allocate render pool for smooth 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 smooth rasterizer.

[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.
* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
(TT_DriverRec): Remove `context' member.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
`TT_ExecContext' code related to a global `TT_Driver' object.

(tt_size_done_bytecode): ... here.
(tt_driver_init): Don't create `TT_ExecContext' object here but ...
(tt_size_init_bytecode): ... here, only on demand.
* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
code.
(TT_New_Context): Remove `TT_ExecContext' code related to a global
`TT_Driver' object.
* src/truetype/ttinterp.h: Updated.
* src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.

[autofit] Allocate AF_Loader on the stack instead of AF_Module.
Stop sharing a global `AF_Loader'. Allocate one on the stack during
glyph load.
Right now this results in about 25% slowdown, to be fixed in a
following commit.
With this patch loading glyphs from different faces from different
threads doesn't immediately crash in the autohinting loader code.
