That is very helpful, I will start looking into getting a verices list for my images.
Is it possible to extend this so that I can use my own images Instead of using some fixed color in the shape? [eg I have an image of man's arm and it has shades in it. So can I use it as the object that is being displayed?] And is it also possible to zoom in/out if I take this approach or do i have to consider doing something else? I am asking this since I am assuming that the vertices that I obtain will limit me use some standard px sizes in my Layout. Thanks again Frank.
