Hey guys, I’m new here but I’ve been using the site as a resource for a while. I’ve got a tough problem. I have .ppm files which are the result of using a segmentation algorithm on images of things. These basically look like a jigsaw puzzle of randomly colored funny-shaped segments. I’d like for each segment to be selectable. I want them to change color on mouseover, so I can’t just use bitmapData.getColorBounds (that’s the best thing I could find searching for possible solutions). As far as I know, the best way to make a specific shape selectable is to draw a polygon using graphics.lineTo, etc. Assuming that that is true, is there any way to draw a polygon that roughly follows a jaggedly-shaped area of a certain color? Or is this just not something flash can handle?

Thanks so much!
