"create a local variable where you place your rotation as a complex number (rot) and then do GETPIX_P(G1,(x,y)*rot)"

Thank you for your idea! It should help, but the output format of, "(x,y)*rot" doesn't seem to be compatible with the GETPIX_P[(G],x,y) function. The output is of the form "(x,y)" and the additional overhead to break x and y out of the parens, negates any speed gain.

It's possible I'm not doing something quite right according to your plan, though. If convenient, could you elaborate a bit?

Thanks!
