|

- CHANGES TO THE HIGH-LEVEL API
|
||||
|
||||
o FT_Get_Kerning has a new parameter that allows you to select
|
||||
the coordinates of the kerning vector ( font units, scaled,
|
||||
scaled + grid-fitted ).
|
||||
|
||||
o the outline functions are now in <freetype/ftoutln.h> and not
|
||||
part of <freetype/freetype.h> anymore
|
||||
|
||||
o <freetype/ftmodule.h> now contains declarations for
|
||||
FT_New_Library, FT_Done_Library, FT_Add_Default_Modules
|
||||
|
||||
o the so-called convenience functions have moved from "ftoutln.c"
|
||||
to "ftglyph.c", and are thus available with this optional component
|
||||
of the library. They are declared in <freetype/ftglyph.h> now..
|
||||
|
||||
o anti-aliased rendering is now the default for FT_Render_Glyph
|
||||
(i.e. corresponds to render_mode == 0 == ft_render_mode_normal).
|
||||
To generate a monochrome bitmap, use ft_render_mode_mono, or the
|
||||
FT_LOAD_MONOCHROME flag in FT_Load_Glyph/FT_Load_Char.
|
||||
|
||||
FT_LOAD_ANTI_ALIAS is still defined, but values to 0.
|
||||
|
||||
o <freetype/freetype.h> now include <freetype/config/ftconfig.h>,
|
||||
solving a few headaches :-)
|
||||
|
||||
o the type FT_GlyphSlotRec has now a "library" field.
|
||||
|
||||
|
||||
|
||||
- CHANGES TO THE "ftglyph.h" API
|
||||
|
||||
This API has been severely modified in order to make it simpler,
|
||||
clearer, and more efficient. It certainly now looks like a real
|
||||
"glyph factory" object, and allows client applications to manage
|
||||
(i.e. transform, bbox and render) glyph images without ever knowing
|
||||
their original format.
|
||||
|
||||
- added support for CID-keyed fonts to the CFF driver.
|
||||
maybe support for pure CFF + CEF fonts should come in ??
|
||||
|
||||
|
|
@ -13,6 +51,22 @@ LATEST CHANGES
|
|||
Also removed the use of "cidafm" for now, even if the source files
|
||||
are still there. This functionality will certainly go into a specific
|
||||
module..
|
||||
|
||||
|
||||
|
||||
- ADDED SUPPORT FOR THE AUTO-HINTER
|
||||
|
||||
It works :-) I have a demo program which simply is a copy of "ftview"
|
||||
that does a FT_Add_Module( library, &autohinter_module_class ) after
|
||||
library initialisation, and Type 1 & OpenType/CFF fonts are now hinted.
|
||||
|
||||
CID fonts are not hinted, as they include no charmap and the auto-hinter
|
||||
doesn't include "generic" global metrics computations yet..
|
||||
|
||||
Now, I need to release this thing to the FreeType 2 source..
