include/freetype/config/ftmodule.h: updated to correctly support
sub-pixel rendering
* include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
ft_encoding_symbol to be FT_ENCODING_MS_SYMBOL (instead of
the erroneous FT_ENCODING_SYMBOL)
* builds/unix/unix-def.in: added "datadir" definition
(thanks to Anthony Fok)
to slightly increase the contrast of smooth hinting. This is very similar
to what the auto-hinter does when it comes to stem width computations.
However, it produces better results with well-hinted fonts..
want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.
of the "load_flags" parameter of FT_Load_Glyph and FT_Load_Char from
"FT_Int" to "FT_Int32", this in order to support more options.
this should only break binary and/or source compatibility on
16-bit platforms (Atari?)
the SFNT loader to check for SFNT-based font files differently. We now
ignore the range "helper" fields and check the "head" table's magic
number instead.
src/psaux/psobjs.c, src/type1/t1load.c, src/type1/t1tokens.h:
fixing a bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.
to support charmaps for CFF fonts
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c,
src/cff/cffgload.h: adding support for CFF charmaps, reformatting the
sources, and removing some bugs in the Encoding and Charset loaders
* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
(ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
syntax of the FT2_DEBUG environment variable used to control debugging
output (i.e. logging and error messages). It must now look like:
any:6 memory:4 io:3 or
any:6,memory:4,io:3 or
any:6;memory:4;io:3
freetype/internal/ftobjs.h, freetype/internal/psaux.h,
freetype/internal/pshints.h, src/psaux/t1decode.c, src/cff/cffgload.h,
src/cff/cffgload.c, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c,
src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: Adding support for hinter-specific bit flags,
and the new FT_Set_Hint_Flags high-level API
incorrect advances when the outline resolution was different from the
metrics resolution
* src/autohint/ahhint.c: removing compiler warnings
* src/autohint/ahglyph.c: slight improvements to the serif detection
code. More work is needed though..
* src/autohint/ahglobal.c, src/autohint/ahtypes.h, src/autohint/ahhint.c:
small improvements to the automatic hinter. un-even stem-widths have now
disappeared and everything looks much better, even if there are still
issues with serifed fonts.
