I tried that, and there's no *easy* way AFAICT. The only thing I could think of would be to make it a multi-step process: 1) Take the original image (img "orig"), duplicate it (img "dupe") and lock its loc. 2) Set the rect of "dupe" to the same size as the polygon 3) Make a new image object (img "stretch") that has the same size as the copy. 4) Set the imageData of the "stretch" to the imageData of "dupe" 5) Set the backgroundPattern of the polygon to "stretch" This of course couldn't happen dynamically in real time without stuttering, etc., especially on larger images. I miss SuperCard's manipulation of pictureData in Revolution (you can do all sorts of other things too like setting offsets, magnification etc.) - it would be a great addition to Rev...
