Subject: [ft-devel] Unix Font Performance/Rendering patches available
I'm proud to announce a new page, containing patches for various libraries
using FreeType, in order to improve performance and/or rendering quality
on Unix systems. You'll find it at:
you'll find two patches at the moment, one speeds up fontconfig cache
regeneration speed in important ways for systems that have not upgraded
to FreeType 2.2
the other one implements ClearType-like LCD filtering, and fixes
to enable light-hinted subpixel rendering. This feature might ultimately be
implemented within FreeType, but I'm still too unsure of the patent
regarding this technology to do that now.
I'm currently using light-hinted subpixel rendered text on my desktop,
rather delicous :-)
More patches are in the work, but I prefer not to announce anything.
You'll also notice that I recently commited a huge set of optimizations
FreeType CVS that speeds up TrueType glyph loading (with hinting) by 25% on
x86 Linux. This has the effect of further reducing fontconfig's cache
which runs in 8.5 seconds, instead of 20.5 (I added fonts since my last

PS: I've sent my patch to the fontconfig mailing list, but it seems to
reached them. I also tried three times to join the list, but this
has never worked.
Could someone do something about it ? Keith Packard, are you reading ?
