Hi,
I'm presently investigating why openoffice fonts look more blurry with
freetype-2.2.1 than with freetype-2.1.10, see this thread
http://lists.nongnu.org/archive/html/freetype/2006-09/msg00050.html
I think finally I found the reason whats the problem:
in vcl/source/glyphs/gcach_ftyp.cxx:857
#if (FTVERSION >= 2005) || defined(TT_CONFIG_OPTION_BYTECODE_INTERPRETER)
if( nDefaultPrioAutoHint <= 0 )
#endif
mnLoadFlags |= FT_LOAD_NO_HINTING;
#ifdef FT_LOAD_TARGET_LIGHT
// enable "light hinting" if available
if( !(mnLoadFlags & FT_LOAD_NO_HINTING) && (nFTVERSION >= 2103))
mnLoadFlags |= FT_LOAD_TARGET_LIGHT;
#endif
So when the bytecode interpreter and light-hinting is available, it will
set "FT_LOAD_TARGET_LIGHT".
Now, referring to David Turner (see
http://lists.nongnu.org/archive/html/freetype/2006-09/msg00045.html), the
bytecode interpreter won't be used if light-hinting is enabled.
May I ask why gcach_ftyp.cxx is trying to handle all this stuff itself and
not just asking fontconfig? I mean, I see there is
vcl/source/gdi/fontcfg.cxx, so somehow fontconfig is used. But why aren't
its defaults used for hinting as well?
Thanks,
Bernd
