restore

Hi there,

I'm working on an iPhone app that lets the user draw using GL. I used the GLPaint sample code project as a firm foundation, but now I want to add the ability for the user to load one of their previous drawings and continue working on it.

I know how to get the framebuffer contents and save it as a UIImage. Is there a way for me to take the UIImage and tell GL to draw that?

Any help is much appreciated.
