It would be easiest for me to explain what I've trying to do by posting this link:
I can create an SWF that rotates a vector-based logo, but it stays the same height. See how this graphic imitates perspective by making the one side grow smaller and the opposite side grow larger? Is there a way to do this with a symbol in Flash? When I use Free Transform on a movie clip or symbol, it doesn't work. Motion Tweens can only be used on movie clips and symbols, of course.
I can created this effect in After Effects, but the SWF that's exported is composed of rasterized images.
you can use imagedistord (search using google) to imitate perspective in flash.
