From bc210eb163b162ff2e94e5c8f4307715731257f8 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann <1087974@bugs.launchpad.net> Date: Fri, 14 Dec 2012 07:54:24 +0000 Subject: pixman: fix vnc tight png/jpeg support This patch adds an x argument to qemu_pixman_linebuf_fill so it can also be used to convert a partial scanline. Then fix tight + png/jpeg encoding by passing in the x+y offset, so the data is read from the correct screen location instead of the upper left corner.
