LATEST CHANGES
+ - 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 @@
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..
