Image Manipulation library/framework in AS3

Is there a good image manipulation library/framework that can be used in a Flash/Flex application? I'm looking for some distortion effects in fotoflexer.com like bulge, pinch, stretch, squish, Smooth Wrinkles?

Any ideas/开发者_高级运维comments will be appreciated.

Check out Joa Ebert's image processing library. Haven't used it myself but Joa is an amazing developer and a quick glance thru the docs shows a good variety of filters including some of the distortions you're looking for.
