[ cairo v1.8.8, pixman 0.14.0 ]
I'm having a problem when trying to clear the contents of a
clip region - Specifically the border pixels - and was wondering
if anyone can offer any insight?
In the attached sample, I define a clip region, draw to it, then
clear it. However, after doing the clear, the edge pixels are
still (partially) visible, and seemingly weren't cleared.
Am I doing something wrong? Might this be a bug? Or is this
somehow due to subpixel/AA rendering?
If it's a problem with my technique/understanding, can anyone
offer any suggestions about how to proceed? Or point me to
something to read? My code is based on
http://cairographics.org/FAQ/#clear_a_surface, but that doesn't
discuss this particular case.
Many thanks for any info!
