Here's my new ROTATE-SURFACE function: That looks like it might be caused by the way that rotozoom pads the resulting surface. Playing with the surface colorkey/alpha properties should fix it. I don't remember the details right now, but in general it can be a bit tricky to get the desired effect from the rotozoom function. _______________________________________________ application-builder mailing list [email protected] http://www.lispniks.com/mailman/listinfo/application-builder
