Werner Lemberg ad866e2c9a Fix `checking if gcc static flag -static works' test.
On my linux build tree, I receive yes answer in in every package I
build except freetype for this test checking if gcc static flag
`-static' works

On freetype, no is received, unless bzip2 and zlib are disabled using

  ./configure --without-bzip2 --without-zlib

The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
LDFLAGS and this broke static flag test.

* builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after
LT_INIT has run.

Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

* include/freetype/config/ftoption.h, src/devel/ftoption.h
(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include
`ttsubpix.c'.

* src/truetype/ttgload.c: Include `ttsubpix.h'.
[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(tt_get_metrics): Set tweak flags.
(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.
(compute_glyph_metrics): Handle `compatible widths' option.
(tt_loader_init): Handle ClearType GETINFO information bits.

* src/truetype/rules.mk (TT_DRC_SRC): Updated.

* src/truetype/ttinterp.c: Include `ttsubpix.h'.
[Where necessary, changes below are guarded by
TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(Direct_Move, Direct_Move_X): Extended.
(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,

Werner Lemberg 1036409692 [autofit] Return correct linear advance width values.
This was quite a subtle bug which accidentally showed up with glyph
`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;
the first component, `E', has an advance width of 1366 font units,
while the advance width of the composite itself (which looks like
uppercase `E' with dieresis) is 1367 font units.  I think this is
actually a bug in the font itself, because there is no reason that
this glyph has not the same width as uppercase `E' without the
dieresis.  Anyway, it helped identify this problem.

Using the TrueType hinter, the correct value (1367) of `afii10023'
was returned, but the autohinter mysteriously returned 1366.

Digging in the code showed that the autohinter recursively calls
FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
flag.  However, the `linearHoriAdvance' field is still returned as a
scaled value.  To avoid scaling twice, the old code in autofit reset
`linearHoriAdvance', using the `horiAdvance' field.  This seemed to
work since FT_LOAD_NO_SCALE was in use, but it failed actually,
because `horiAdvance' is defined as the distance of the first
subglyph's phantom points, which in turn are initialized using the
advance width of the first subglyph.  And as the given example
shows, these widths can differ.

* src/autofit/afloader.c (af_loader_load_g): Temporarily set
FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
values for the linear advance widths.

2012-01-16 18:51:15 +09:00
suzuki toshiya 3c96681856 Fix redundant declaration warning in PIC mode.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h).  Separating to other header files
are needed for multi build.

* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
Remove class_##_pic_free and class_##_pic_init declarations.
* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
FT_DEFINE_MODULE): Ditto.

* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be

of `clazz', `glyph', `library' and NULL pointer check are
reordered to minimize PIC conditonals.

* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
configuration, FT_DEFAULT_MODULES_GET returns
FT_Module_Class** pointer, GCC 4.6 warns that
const FT_Module_Class* const* variable is warned as
inappropriate to store it.  To calm it, explicit cast is
inserted.  Also `library' is checked to prevent the NULL
pointer dereference in FT_DEFAULT_MODULES_GET.

suzuki toshiya 714ee56ab1 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code.  Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).

* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.
* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
requested.

Werner Lemberg ed54e43aed [bdf] Fix Savannah bug #34896.
ENCODING now covers the whole Unicode range.

Note, however, that this change is quite expensive since it
increases the size of three arrays by almost 400kByte in total.  The
right fix is to replace the logic with something smarter.
Additionally, there exist very old BDFs for three-byte CCCII
encoding which exceeds the range of Unicode (another reason to have
a smarter logic).

* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
arrays.
* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.

Tomas Hoger 487913d9a6 Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes.  This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.
2011-09-11 09:18:10 +02:00
Tomas Hoger 83cb6c0049 Add explicit LZW decompression stack size limit.
Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
constructed correctly.  It's even less than that, see e.g.
libarchive code comment for a better size upper bound:

  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121

This patch adds explicit stack size limit, enforced when stack is
realloced.

An alternative is to ensure that code < state->prefix[code - 256]
when traversing prefix table.  Such check is less efficient and
should not be required if prefix table is constructed correctly in
the first place.

* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
2011-09-11 09:13:45 +02:00
Tomas Hoger 86c3c69c15 Protect against loops in the prefix table.
LZW decompressor did not sufficiently check codes read from the
input LZW stream.  A specially-crafted or corrupted input could
create a loop in the prefix table, which leads to memory usage
spikes, as there's no decompression stack size limit.

* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
code in valid LZW stream must be 0..255.
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
code > free_ent is invalid.
