--- Comment #12 from Owen Taylor <[EMAIL PROTECTED]> 2008-04-13 08:56:44 PST --- Created an attachment (id=15878) --> (http://bugs.freedesktop.org/attachment.cgi?id=15878) Trial patch to use border color on R100/R200 Here's a patch that tries using the border color on R100/R200 (taking the advantage of the fact that it is always ARGB in a fixed format.) However, it fails on R100 because the hardware doesn't seem smoothly blend with the border color using linear interpolation, but rather to abruptly just use the border color for pixels near the edge. I'll attach a test that demonstrates this with expected and actual output. I reproduced the same behavior using an OpenGL program, so I don't think it's misprogramming of the hardware, though obviously some missing element could be shared between Mesa and the 2D driver. I have not yet tested on R200. The easy test would be to try the GL program, which I'll attach as well. Compile with: gcc -g -Wall -o gl-border-test gl-border-test.c `pkg-config --cflags --libs gl glu` -lglut And run as: ./gl-border-test +linear -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
