`extra_light' members.
* src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize

corresponding code.
(Ins_MD): Last regression fix.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues

builds/win32/visualc/freetype.vcproj: s/230/231/.
* builds/win32/visualc/index.html: s/221/231/.
* vms_make.com: Add `ftgasp'.
2007-01-30 David Turner <david@freetype.org>

* builds/unix/configure.raw (version_info): Set to 9:12:3.
2007-01-30 11:40:23 +01:00
* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
(af_loader_load_g): Disable the warper (i.e., the light hinting
improvements) to make a 2.3.1 bugfix release before introducing a
new feature. This should give us more time to tune and improve the
warper for the next release.
2007-01-30 11:40:23 +01:00
* docs/CHANGES: Update accordingly.
2007-01-25 David Turner <david@freetype.org>
2007-01-26 17:08:49 +01:00
For light auto-hinting, improve glyph advance widths and resurrect
normal/full hinting to its normal quality.
* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
and `xmax_delta'.
* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
and `xmax_delta'.

* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
2007-01-25 14:53:56 +01:00
correctly in a sanity check. Since this function is only used to
load local and global functions, any charstring that called the last
local/global function would fail otherwise. This fixes Savannah bug
#18867.
* docs/CHANGES: Document it.
2007-01-23 David Turner <david@freetype.org>
* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that

* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
Remove a typo that results in no hinting and a memory leak with some
large Asian CFF fonts.
* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
2007-01-05 14:17:15 +01:00
which happens when FT_Done_Library is called with still opened
CFF_Faces in it. We need to close all faces before destroying the
modules, or else some bad things (memory leaks) may happen.
2007-01-02 Werner Lemberg <wl@gnu.org>
* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
Remove compiler warning.

v5 under AIX 4.3 doesn't like this.
2006-12-07 David Turner <david@freetype.org>
2006-12-08 07:49:33 +01:00
* src/autofit/afloader.c (af_loader_load_g): Small adjustment

program after a change from mono to grayscaling (and vice versa).
Use correct constant for comparison to get `exec->grayscale'.
2006-11-18 Werner Lemberg <wl@gnu.org>
Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.
* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c

2006-11-13 14:24:30 +01:00
2006-11-10 David Turner <david@freetype.org>
2006-11-14 11:37:10 +01:00
* src/smooth/ftsmooth.c: API change for the LCD
filter. The FT_LcdFilter value is an enumeration describing which
filter to apply, with new values FT_LCD_FILTER_LIGHT and
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
algorithm which produces strong color fringes for everything
except very-well hinted text).

Add a few tweaks to better handle serif fonts.
Add more debugging messages.
* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
segments that are less than 1.5 pixels high. This gets rid of

These functions. Update all callers.
(FT_Add64) [!FT_LONG64]: Simplify.
* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.

* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
Add a new API to support color filtering of subpixel glyph bitmaps.
2006-09-29 23:31:53 +02:00
In a default build, the function `FT_Library_SetLcdFilter' returns
`FT_Err_Unimplemented_Feature'; you need to #define
FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
real implementation.
* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.
2006-09-29 23:31:53 +02:00

2006-09-29 23:31:53 +02:00
* include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
pointing to <freetype/ftlcdfil.h>.
2006-09-29 23:31:53 +02:00
* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.
2006-09-29 23:31:53 +02:00

correctly. Reported as Savannah bug #17843.
2006-09-26 David Turner <david@freetype.org>
2006-09-26 23:55:44 +02:00
* src/autofit/afhints.h (AF_HINTS_DO_HORIZONTAL,
AF_HINTS_DO_VERTICAL, AF_HINTS_DO_ADVANCE): New macros to disable
horizontal and vertical hinting for the purpose of debugging the
auto-fitter.
* src/autofit/afmodule.c (_af_debug_disable_horz_hints,
_af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.
* src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.
* include/freetype/config/ftoption.h, devel/ftoption.h
(FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
we want to compile LCD-optimized rendering code (à la ClearType) or
not. The macro *must* be disabled in default builds of the library
for patent reasons.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
isn't defined at compile time. This only changes the content of the
rendered glyph to match the one of normal gray-level rendering,
hence clients should not need to be modified.
* docs/CHANGES: Updated.
CHANGES BETWEEN 2.2.1 and 2.2.2 I. IMPORTANT BUG FIXES - Various integer overflows have been fixed. - PFB fonts with MacOS resource fork weren't handled correctly on non-MacOS platforms. - The PCF font loarder has been seriously hardened against malformed font files. II. IMPORTANT CHANGES - the unpatented hinter is now part of the default build of the library, and we added code to automatically support "tricky" fonts that need it. what this means is that FreeType should "just work" with certain Asian fonts, like MingLiu, which cannot properly load without a bytecode interpreter, but fortunately do not use any of the patented bytecode opcodes. Note that the API didn't change, so you can still force unpatented hinting with a special parameter to FT_Open_Face as well. if you're an embedded systems developer, you might want to *disable* the feature to save code space by undefining TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h. - LCD-optimized rendering is now disabled in all default builds of the library, mainly due to patent reasons. For more information see: http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has been introduced in ftoption.h; manually define it in this file if you want to re-enable the feature. the change only affects the implementation, not the FreeType API. This means that clients don't need to be modified, because the library still generates LCD decimated bitmaps, but with the added constraint that R=G=B on each triplet. - Some computation bugs in the TrueType bytecode interpreter were found, which allow us to get rid of very subtle and rare differences we had with the Windows renderer. III. MISCELLANEOUS - TrueType glyph loading is now about 25% faster. - the anti-aliased rasterizer has been optimized and is now 15% to 25% percent faster than the previous one, depending on content - the Type 1 loader has been improved; as an example, it now skips over top-level dictionaries properly ======================================================================

Apply patch by Derek Clegg to fix two memory leaks in the MacOS
2006-06-04 17:17:41 +02:00
resource fork handler. This fixes Savannah bug #16631.
2006-05-20 10:47:01 +02:00
* src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
`FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

* build/unix/configure.raw: Add a fallback to disable Carbon
dependency, if configured with no options on Mac OS X.
2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
2006-05-20 10:47:01 +02:00
its content cannot be parsed as supported font. This fixes
the second part of Savannah bug #16590.
2006-05-18 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

This is a major patch used to drastically improve the performance of
loading glyphs. This both speeds up loading the glyph vectors
themselves and the auto-fitter module.
We now use inline assembler code with GCC to implement `FT_MulFix',
which is probably the most important function related to the
engine's performance.
The resulting speed-up is about 25%.
* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
`cursor' and `limit'.
* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
New functions.
(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
[TEST]: Remove.
* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
code.
* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
`FT_ZERO'
(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
(af_glyph_hints_reload: Rewrite recognition of weak points.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
constant values out of the loops.
* src/autofit/aftypes.h: Updated.
* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
product to get orientation.
* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
(FT_Stream_OpenGzip): Use it to handle small files directly in
memory.
* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
Improve performance.
* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
`limit'.
(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
TT_Load_Composite_Glyph): Updated. Add threshold to protect against
exceedingly large values of number of contours. Speed up by
reducing the number of loops.
* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
used to detect rogue clients from 4 to 16. This is to prevent some
segmentation faults with fonts like `KozMinProVI-Regular.otf' which
comes from the Japanese Adobe Reader Asian Font pack.
2007-05-17 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
fixes the first part of Savannah bug #16590.
2006-05-16 Werner Lemberg <wl@gnu.org>
* docs/PROBLEMS: Updated icl issues.
