Is there a way to apply some functions like:brightness,contrast,sharpness,hue,saturation,exposure to uiimages. For example I have a UIImageview and inside that i have a uiimage. I want to manipulate its brightness or contrast or sharpness with a help of UISlider
Have a look at the sample app GLImageProcessing, however it uses openGL to do the image processing, but it is really fast.
