* docs/PATENTS: Slightly reworded. Suggested by Sylvain Beucler
<beuc@gnu.org>.
2005-06-04 Werner Lemberg <wl@gnu.org>
* include/freetype/ftimage.h (FT_Outline_MoveToFunc,
FT_Outline_LineToFunc, FT_Outline_ConicToFunc,
FT_Outline_CubicToFunc, FT_Raster_RenderFunc),
include/freetype/ftrender.h (FT_Glyph_TransformFunc,
FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Don't use
`const' to stay compatible with FreeType 2.1.9.
2005-06-01 Adam D. Moss <adam@gimp.org>
* src/base/ftstroke.c (ft_stroker_inside): Revert `sigma' patch from
2004-07-11; this gives much better results under normal
circumstances.
2005-05-30 Chia I Wu <b90201047@ntu.edu.tw>
* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Minor
documentation improvements.
* include/freetype/ftoutln.h (FT_Outline_Embolden): Fix typos.
* src/base/ftbitmap.c (FT_Bitmap_Embolden): Add support for bitmap
of pixel_mode FT_PIXEL_MODE_GRAY2 or FT_PIXEL_MODE_GRAY4.
If xstr is larger than 8 and bitmap is of pixel_mode
FT_PIXEL_MODE_MONO, set xstr to 8 instead of returning error.
2005-05-29 Chia I Wu <b90201047@ntu.edu.tw>
* src/base/ftbitmap.c (FT_Bitmap_Embolden): Fix emboldening bitmap
of mode FT_PIXEL_MODE_GRAY. Also add support for mode
FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V.
(ft_bitmap_assure_buffer): FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V
should have ppb (pixel per byte) 1.
Zero the padding when there's no need to allocate memory.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle slot->advance
too.
More suited emboldening strength.
2005-05-28 Chia I Wu <b90201047@ntu.edu.tw>
* src/base/ftbitmap.c (FT_Bitmap_Embolden): Handle negative pitch.
Handle FT_PIXEL_MODE_GRAY with num_gray != 256.
Improve speed for FT_PIXEL_MODE_GRAY.
(ft_bitmap_assure_buffer): Accept FT_PIXEL_MODE_LCD and
FT_PIXEL_MODE_LCD_V.
2005-05-27 Chia I Wu <b90201047@ntu.edu.tw>
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Initialize `error'.
* src/base/ftobjs.c (ft_cmap_done_internal): New function.
(FT_CMap_Done): Remove cmap from cmap list.
(destroy_charmaps, FT_CMap_New): Don't call FT_CMap_Done but
ft_cmap_done_internal.
2005-05-26 Werner Lemberg <wl@gnu.org>
* docs/GPL.txt: Update postal address of FSF.
2005-05-26 Chia I Wu <b90201047@ntu.edu.tw>
* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Improve
documentation.
* src/base/ftsynth.c (FT_BOLD_THRESHOLD): Removed.
(FT_GlyphSlot_Embolden): Check whether slot is bitmap owner.
Always modify the metrics.
2005-05-24 Werner Lemberg <wl@gnu.org>
* docs/CHANGES: Updated.
2005-05-24 Chia I Wu <b90201047@ntu.edu.tw>
* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): New declaration.
* include/freetype/ftoutln.h (FT_Outline_Embolden): New declaration.
* src/base/ftbitmap.c (ft_bitmap_assure_buffer): New auxiliary
function.
(FT_Bitmap_Embolden): New function.
* src/base/ftoutln.c (FT_Outline_Embolden): New function.
* src/base/ftsynth.c: Don't include FT_INTERNAL_CALC_H and
FT_TRIGONOMETRY_H but FT_BITMAP_H.
(FT_GlyphSlot_Embolden): Use FT_Outline_Embolden or
FT_Bitmap_Embolden.
2005-05-24 Werner Lemberg <wl@gnu.org>
* configure: Always remove config.mk, builds/unix/unix-def.mk, and
builds/unix/unix-cc.mk. This fixes repeated calls of the script.
Reported by Nelson Beebe and Behdad Esfahbod.
* README.CVS: Mention file permissions.
2005-05-23 Werner Lemberg <wl@gnu.org>
* builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c --
it is currently loaded from ttsbit.c.
2005-05-23 Behdad Esfahbod <behdad@cs.toronto.edu>
Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing. The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'. But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error. The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.
* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.
Cast temporarily to (void*) to not break strict aliasing.
* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
to not break strict aliasing.
* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.
* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.
2005-05-23 David Turner <dturner@freetype.org>
Fix Savannah bug #12213 (incorrect behaviour of the cache sub-system
in low-memory conditions).
* include/freetype/cache/ftccache.h (FTC_CACHE_TRYLOOP,
FTC_CACHE_TRYLOOP_END): New macros.

2005-02-25 David Turner <david@freetype.org>
Implement several memory optimizations to drastically reduce the
heap usage of FreeType, especially in the case of memory-mapped
files. The idea is to avoid loading and decoding tables in the
heap, and instead access the raw data whenever possible (i.e., when
it doesn't compromise performance).
This has several benefits: For example, opening vera.ttf now uses
just a small amount of memory (even when the FT_Library footprint is
accounted for), until you start loading glyphs. Even then, you save
at least 20KB compared to the non-optimized case. Performance of
various operations, including open and close, has also been
dramatically improved.
More optimizations to come, especially for the auto-hinter.
* include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New
function type.
(SFNT_Interface): Add it.

`hdmx_record_sizes', `kern_table', `kern_table_size,
`num_kern_tables', `kern_avail_bits', `kern_order_bits' if
FT_OPTIMIZE_MEMORY is set.
Don't define `hdmx', `num_kern_pairs', `kern_table_index',
`kern_pairs' if FT_OPTIMIZE_MEMORY is set.

all allocation sites in the memory debugger. Also a new function
FT_DumpMemory() was added. It is only available in builds with
FT_DEBUG_MEMORY defined, and you must declare it in your own code to
use it, i.e., with something like:
extern void FT_DumpMemory( FT_Memory );
...
FT_DumpMemory( memory );

read directly from memory-mapped streams, instead of being decoded
into the heap.

bytecode interpreter is compiled in.
