[truetype] Introduce named instance access to GX fonts.
|
||
|
||
For functions querying a face, bits 16-30 of the face index can hold
|
||
the named instance index if we have a GX font. The indices start
|
||
with value 1; value 0 indicates font access without GX variation
|

data.

|
||
[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...
|
||
|
||
* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
|
||
to embedded TTF's glyph index.
|
||
|
||
2015-08-08 Werner Lemberg <wl@gnu.org>

[type42] Parse FontMatrix according to specifications.
|
||
|
||
* src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix

does not need scaling by 1000. Units_per_EM are taken from the
|

embedded TrueType.

[base] Implement fast vector normalization.

The function uses Newton's iterations instead of dividing vector

literally, a bit less accurate but a lot faster.

instead we move `ft2build.h' up by one level so that it gets

/usr/local/include). After this commit, only `ft2build.h' stays in

the compiler's include path.

Make Jam support work again.
|

|
||
|
||
[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/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
|

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'
|

(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
|
||
`GS.instruct_control' is active.

|

[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).

||

|

|

[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

[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'.

|
||
|
||
[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'.

|
||
(FT_Add_Module): Don't call `FT_GlyphLoader_New'.

|

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.

[base] Do not reorder library->renderers upon use.

With this patch, rasterizing glyphs from different faces from

[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.

[autofit] Allocate AF_Loader on the stack instead of AF_Module.
|
||
|
||
Stop sharing a global `AF_Loader'. Allocate one on the stack during

[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'.

[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.

|
||
|
||
[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 <wl@gnu.org>
|
||
|
||
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 <wl@gnu.org>
|
||
|
||

|
||
|
||
. Add and update many `<Order>' tags.
|
||
. Apply various documentation fixes.
|
||
. Remove details to deprecated (or never implemented) data.
|
||
|
||
2014-12-02 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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 <wl@gnu.org>
|

|
||

||
|
||
* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
|
||
Emit `/empty/' string for first element also.
|
||
|
||
2014-12-02 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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 <wl@gnu.org>
|
||
|
||
[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 <wl@gnu.org>
|
||
|
||
[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 <wl@gnu.org>
|
||
|
||
[docmaker] Use field values as HTML link targets where possible.
|
||
|
||
* 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 <wl@gnu.org>
|
||
|
||
[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 <wl@gnu.org>
|
||
|
||
* src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp.
|
||
|
||
After the single asterisk there must be no other immediately following
|
||
asterisk.

|
||
together with proper CSS.
|
||
|
||
2014-11-29 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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'.

|
||
|
||
* src/tools/docmaker/tohtml.py: Fix index and TOC templates.
|
||
|
||
This thinko was introduced 2014-11-27.
|
||
|
||
2014-11-28 Werner Lemberg <wl@gnu.org>
|
||
|
||
[docmaker] Format field lists with CSS.
|
||
|

|
||
(HtmlFormatter::block_enter): s/<h4>/<h3>/.

|
||
|
||
* 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.
|
||
|
||

[Savannah bug #43682] Add/remove `void' casts to some functions.
|

We use a cast to indicate that we intentionally ignore a function's

errors can only happen for trivially invalid input.

[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.

Avoid compiler warnings on x86-64 for `FT_MulFix'.
|

|

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

but several inline implementations of it in `ftcalc.h' take
|
||
`FT_Int32' arguments. This is causing compiler warnings on x86-64:
|
||
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the

inline implementation of this function, integer values are truncated
|
||
from 64bit to 32bit.

* 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.

[base] Significant optimization of `ft_div64by32'
|
||
|
||
We shift as many bits as we can into the high register, perform

for smaller dividends that barely use the high register.

[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.
|
||
|

|
||
handled properly.
|
||
Don't check blue zone characters for default coverage.

||

2014-04-12 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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'.

[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.
|
||
(af_latin_hints_detect_features): Pass stem width array and array
|
||
size.
|
||
(af_latin_metrics_init_widths): Updated to use original algorithm.
|
||
(af_latin_hints_apply): Updated to use new algorithm.

* src/autofit/aflatin.h: Updated.

Avoid `long long' warnings with older gcc compilers.
|

Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
|
||
|

* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for

[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.
|

|

2013-12-30 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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.

* src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with

[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.

2013-12-21 Werner Lemberg <wl@gnu.org>
|
||
|
||
[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.
|
||
|
||
* devel/ftoption.h, include/config/ftoption.h

||
(AF_StyleClassRec): New member `coverage'.
|
||
(AF_DEFINE_STYLE_CLASS): Updated.
|
||
|
||
* include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
|
||
data.

[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)
|

||
|
||
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
|

|
||
`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.

|

|

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.

`--cflags', return a single directory.

|

|
||
[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'

|

|

this structure only as a pointer through `FT_Get_Sfnt_Table', there
|
||
shouldn't be any ABI problems.

[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.

* 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.

* 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'

FT_Open_Face: Improve external stream handling.
|
||
|

If the font's `clazz->init_face' function wants to swap to new

external streams properly.

Better tracing of loaded glyphs.

Previously, the loading of a glyph was traced at level 4, if at all.

[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.

[autofit] Improve handling of `near' points.
|
||
|
||
Points which are very near to each other are now marked as such.
|

The `weak' flag is then computed by using the `in' vector of the
|
||
first and the `out' vector of the last point of a group of near
|
||
points.
|
||
|

For example, this fixes the rendering of glyph `Oslash' in

is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
|
||
Store good `in' vector (of last non-near point) in
|
||
`last_good_in_{x,y}' and use it as an argument to
|

`ft_corner_is_flat' if necessary.

[autofit] Introduce `writing systems'.
|
||
|
||
This patch adds a new top level to the auto-hinter's script class
|
||
hierarchy. It defines `writing systems' which can contain multiple
|
||
scripts.
|
||
|
||
For example, the `latin' writing system (in file `aflatin.c') is
|
||
able to support scripts like Latin, Cyrillic, Armenian, etc., which
|
||
can be handled similarly.
|
||
|

|

This is a major change which should improve the rendering results

enormously for many TrueType fonts, especially in the range approx.

Optimize FT_MulFix for x86_64 GCC builds.
|
||
|
||
This patch provides an optimized `FT_MulFix' implementation for
|
||
x86_64 machines when FreeType is built with GCC, or compatible
|
||
compilers like Clang.

||
|

|
||
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:

|
||
|
||
Note that the current version heavily chokes on FreeType, delivering
|
||
many wrong results. I will report those issues to the cppcheck team
|
||
so that a newer version gives improved results hopefully.
|
||
|
||
*/* Improve variable scopes.
|
||
*/* Remove redundant initializations which get overwritten.
|
||
|
||
* src/base/ftmac.c, builds/mac/ftmac.c (count_faces_scalable):
|
||
Remove unused variable.
|
||
|
||
* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.
|
||

2013-06-03 Werner Lemberg <wl@gnu.org>
|
||
|
||
Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option.
|
||
|
||
This controls whether the old FreeType CFF engine gets compiled into
|
||
FreeType. It is now disabled by default.

||
|
||
* devel/ftoption.h, include/freetype/config/ftoption.h
|
||

|
||
CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code.

2013-05-23 Behdad Esfahbod <behdad@google.com>
|
||
|
||
Add support for color embedded bitmaps (eg. color emoji).
|
||
|
||
A new load flag, FT_LOAD_COLOR, makes FreeType load color
|
||
embedded-bitmaps, following this draft specification
|
||
|
||
https://color-emoji.googlecode.com/git/specification/v1.html
|
||
|
||
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
|
||
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
|
||
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.
|
||
|
||
Note that color bitmaps are converted to grayscale if client didn't
|
||
ask for color.
