Can anyone tell me how to make an opaque image transparent again? I
want to redraw an image, but I need to initially make it completely
transparent so it doesn't block highlighting in a table view. I will
need to erase the old drawing first, make it transparent and draw it
again. A new NSImage is allocated and initialized completely
transparent. How can I get back to this state without having to create
a new image?
Thanks,
Keith
