Expand shape?

Hey guys, I had a technique question, I have a graphic of a long rounded rectangle, and its a photoshop-produced graphic so its fancy and nonvector and all that.

I also have a squareish version of it (still rounded corners, but L and W are same, as opposed to being a rectangle) and I’d like to know how to expand the squarish one to form the original rectangle graphic :slight_smile:

Let me know on your techniques =D
