Is there any nice, clean way to antialias a region? I do not mind doing it "unsafe".
Here is what I have: a small transparent bitmap with a single (filled with one or 2 colors brush) shape. Shape is resulted from region>path intersection.
I tried to use 2 graphics paths alone (automatically solves antialiasing problem). But because resulted shape must be a Photoshop "subtract path" equivalent, I was unable to find any solution to fully subtract one path from another.
So I'm thinking going with a region, then getting pixels from memory, finding shape edges.. but that is as far as I went. If anyone can point me to the right direction as to what to do next, possibly has algorithm for the alpha at edges, or has more elegant solution to the problem.
