Subject: Patch to enable Quartz font smoothing on MACOSX
Date: Tue, 12 Aug 2003 12:10:44 -0500 (CDT) [thread overview]
Message-ID: <Pine.GSO.4.55.0308121159060.13847@astro.as.utexas.edu> (raw)
Hi everybody,
Here is a patch to src/macterm.c which enables Quartz font smoothing on
Mac OS X using Carbon. This works on Mac OS X version 10.1.5 and later.
I've enclosed the changes in #ifdef ENABLE_QUARTZ_FONT_SMOOTHING which
could be set by a new option to configure (--enable-quartz-font or
something like that). If Quartz font smoothing is welcome, I'll be happy
to provide this as well. The patch is against cvs as of Aug 12 2003 17:00
CEST.
I cannot test the patch on Mac OS X prior to 10.2 nor in classic/Mac OS
7-9 since I have no access to such machines.
Thanks to everybody for their great work on EMACS,
Cheers,
Niv
