Thank you to everyone who posted a suggestion.

The end result has to be a GIF preserving the PNG's transparent background.

I'm actually stuck ¬____¬ delight help me.

Thank you in advance for any advice you tin can provide.

Edit: To evidence you an example of why chrislondon's second example does not work, I have drawn a one-half circle and a full circumvolve in this image and then spun information technology through chrislondon's code (resulting in a .GIF image which is what I want):

The (lumpy)black circle is non filled by me, it is just the transparency in the center not showing through. The (lumpy)circle to the right is not completed all the way leaving a gap then the transparency is filled.

I promise this will articulate up any remaining misunderstandings to what I'm trying to accomplish.
