hi friends,

I want to set Image Brightness and contras of images that are in my photo library, I got the code from http://developer.apple.com/iphone/library/samplecode/GLImageProcessing/Introduction/Intro.html, but that will work on the EAGL layer i.e. all the effects are provided on image that is put initially not on the image that are selected from the photo library ,as this function will work on the view(EAGLview) and not on the image view. so how to change the brightness and contras of any images that are selected from the photo library??

if any one know this please let me know..

regards viral.
