I assume you would create another NSImage and draw the mask-cap to an end, flip it and then draw to the other end, but I do not know how to do this.

I don't know if it will answer all of your questions, but I think this tutorial should point you in the right direction:

Particularly "Overlay Images with Transparency" and "Draw Directly to an Image". There's sample code at the end.
