Bitmap Morph Tween in Actionscript?

How do you do a bitmap开发者_开发知识库 morph tween in Actionscript? I would like to morph a Panel into a Button, using BitmapData or something but I have no idea where to begin.

Fading+resizing will be a simple solution. Any tweening library, like Tweener, Tweenlite will do the job. In this case the Button will be usable after transition too.

If you mean real image morphing, sorry I haven't seen any as3 library for that yet.

The best way is to use a 3rd party morph program and embed the video into Flash.
