Andy Finnell wrote a couple of very good articles on this a while back. http://www.losingfight.com/blog/2007/08/28/how-to-implement-a-magic-wand-tool/ http://www.losingfight.com/blog/2007/08/29/an-alternate-way-to-implement-marching-ants/ The latter uses CoreImage directly on your mask to draw the dotted line, so it's probably a bit quicker than tracing the bitmap.
