Difficult problem.
First question, does it use anti-aliased pixels. If it does you will have a very very hard time. See
http://www.cit.gu.edu.au/~anthony/graph ... k_creation
It it doesn't you can just use -transparent color
or a -draw floodfill of the color to make the background transparent

If you like to submit a summery of your final solution that would be good.
