hi,

I want to set brightness and contrast on the image that is selected from the photo library of iphone, is there any way to do the same using/not using open GLES.

I've got some code from the developer.apple.com but that is for a single image and i can't use images from photo library, do any one know please let me know how to this.

regards viral.
