* include/freetype/internal/ftobjs.h, src/truetype/ttobjs.c,
src/base/ftobjs.c: fixed a bug in the automatic unpatented
hinting support which prevented normal bytecode hinting to
work properly
Fix a bug in the automatic unpatented hinting support which prevents
normal bytecode hinting to work properly.
* src/autofit/aftypes.h: undefining AF_DEBUG to get rid of
traces
* include/freetype/internal/ftobjs.h (FT_Face_InternalRec):
s/force_autohint/unpatented_hinting/. Update all callers.
* src/base/ftobjs.c (FT_Load_Glyph): Updated code.
* src/autofit/aftypes.h (AF_DEBUG): Undefine to get rid of traces.
2006-09-27 David Turner <david@freetype.org>
* include/freetype/freetype.h: bumping FT_FREETYPE_PATCH to 2
for an upcoming 2.2.2 release
* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
* include/freetype/ftlcdfil.h, src/freetype/ftlcdfil.c:
added a new API to support color filtering of subpixel glyph
bitmaps. In 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
* src/smooth/ftsmooth.c: adding support for sub-pixel color
filtering; simplifying a few function calls
Add a new API to support color filtering of subpixel glyph bitmaps.
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/config/ftheader.h: adding FT_LCD_FILTER_H
macro that points to <freetype/ftlcdfil.h>
* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.
* src/base/Jamfile, src/base/rules.mk, vms_make.com: adding
'ftlcdfil.c' to the list of compiled source files
* include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
typedef.
(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
`lcd_filter_weights' and `lcd_filter'.
* modules.cfg: adding ftlcdfil.c to the list of default base
extensions
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
`hmul' and `vmul'.
Handle subpixel rendering.
Simplify function.
(ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
(ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.
* include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
pointing to <freetype/ftlcdfil.h>.
* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.
* modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.
