Question

If i import an external image in as3, is it possible to manipulate it? I would like to have the corners curled a bit like its a piece of paper, would this be possible in code? I thought you could transform images etc but have no idea where to begin.

thanks in advance

Besides the basic manipulations described by @jhocking you can use PixelBender to create more complex effects like the page curl you would like.

PixelBender is not ActionScript; it’s actually an entirely different language and may be pretty hard to grasp at first. There are two steps in creating a PixelBender shader for use in ActionScript:

1. you create a PixelBender kernel and compile it. This kernel will read every pixel of your image, transform it as desired and then return those transformed pixels.
2. you create a ShaderJob that uses this compiled kernel and assign it to the ‘filters’ property of whatever visual component you want to apply the effect to.

You can find an example of a page curl PixelBender shader here: http://superflashbros.net/2010/06/28/a-real-page-turner/
