Re : Simple 2x circular zoom routine

Hi Bill, Ivan, Matt and JG,
Sorry for wasting your valuable brain cycles on this.

A few hours after posting, I realised what I needed to do, which is to
apply a stenciled alpha mask as JG mentioned.

Well at least it is good to know I was on the right track.

Thanks again.
