how to compose images

[til]

I want to compose a picture by drawing multiple alpha-blended sprites.  I already know how to do this once by drawing to the screen.  However, I want to do it in a way that results in another sprite.  

I'm guessing the way to do this would be to draw sprites to an image, and then make a sprite for that image?  How is this best accomplished?

Thanks for any help,

You'll have to wait for the render-to-image feature
