Hi, Chris Is it implemented in cairo-ft-font.c and cairo-user-font.c where if font antialias option is SUBPIXEL/BEST, it always generate ARGB32 image while A8 is for DEFAULT/GRAY/....? In cairo-quartz-font.c - it always generates A8 format surface for glyph? I could see other area that is contradictory to this. Am I correct? Thanks Henry ________________________________________ From: Chris Wilson [[email protected]] Sent: Tuesday, March 27, 2012 2:32 PM To: Henry (Yu) Song - SISA; [email protected] Subject: Re: [cairo] [patch] gl: use font's antialias option to check whether it needs mask On Tue, 27 Mar 2012 21:25:37 +0000, "Henry (Yu) Song - SISA" <[email protected]> wrote: > It seems that we don't need to check each glyphs surface for ARGB32 format. We can use font's antialias option. Yes, in theory this looks correct, which also probably means we can be stricter when generating the glyph surfaces as well. That is also worth investigating. -Chris -- Chris Wilson, Intel Open Source Technology Centre -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
