That's the one I found, and based my code on. The problem I had was that it floods everything until it hits a specific colour - whereas I am looking to flood evertything of one colour, until I hit a different colour. It's almost the same, but something in the edge conditions went wrong, I think. Actually, things were made worse by the fact that I was creating images for a web page, and I hadn't realised that Internet Explorer only seems to respect transparency in GIF files. (I was avoiding GIF, as PIL doesn't compress them, for copyright reasons, as I understand it). I'll go back and look again and see if I can get that algorithm working. Thanks, Paul. _______________________________________________ Image-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/image-sig
