Keep in mind that accessing the image pixels directly can hurt drawing
performance. Your code can only access the pixmap if it's in system RAM, while
GPU acceleration requires that the pixmap be in VRAM. So messing with the
pixels may either cause the pixmap to be copied back and forth, or force

Hi,
I need to create and manipulate an image, which I could access directly
from memory and at the same time be able to use system drawing functions
for optimization. On Windows I can create a memory bitmap, but it seems it
is on possible on Mac, or is it? Note that I don't want to do any
conversi
