Photoshop 7 had a “sperize” tool or something like that, and I think the imageready plugin had something similar but I didn’t like it, not exact enough. Illustrator cs1 has the envelope distort which is really nice, and you can bounce back and forth between the 2 pretty seamlessly, if you have both open you can actually drag and drop between screens. In illustrator, you have to make an empty box over top of what you’re distorting. After you go to envelope distort, your box will have control handles and the way they control the vector line, they’ll control the image distortion. You can add and subtract points to give you more or less control over specific areas, etc…really nice, I highly recommend it, especially if you have to put a graphic on a curved surface or have a pattern turn the corner.
