cocoa-touch

I have a bunch of images that are transformed (using touch gestures). I want to take the transformations the user does to the images and create a jpeg from it. (ie. if a user rotates a photo to the right, I want to get a jpeg of the photo rotate to the right just as the looks on screen). This takes into account that the photo could be bigger than whats displayed on screen too (no screenshots).

I'm trying to use CGContext (CGContextRotateCTM specifically) but its not been too successful.

Thanks for the help.
