It seems like you should just be able to do this: var scaleFactor:Number = .1; image1.scaleX *= (1 + scaleFactor); image1.scaleY *= (1 + scaleFactor); image2.scaleX *= (1 - scaleFactor); image2.scaleY *= (1 - scaleFactor);
That should affect your matrices as necessary. If you're scale factor is like 1.1, 1.2, etc. as you describe, you should be able to do this instead: image1.scaleX *= scaleFactor; image1.scaleY *= scaleFactor; image2.scaleX *= (1 - (scaleFactor - 1)); image2.scaleY *= (1 - (scaleFactor - 1)); I didn't actually try it out, but it seems like it should work.
