Resizable rounded rectangle

[LindaLawton]

I have been trying to figure out how to create a resizable rounded rectangle for a while now.

What I have done is created a system something like a sprite in game development. I have a main image that i then chop up and reuse to stretch the image horizontally and vertically.

This as you may guess leads to a lot of image clips. one for each corner then stretching the middle chop sections.

The more clips i get the longer it takes to generate the video.

Is there a better way of doing this?
