title: Core Image vs Core Graphics
body: <p>I am making an application that uses basic core Graphics functions . The Application runs reasonably well on Ipad2, but there is a performance hit on Ipad3 due to retina display, which causes drawing to be done on number of pixels 4 times to the earlier. I tried some hacks to improve performance, but since drawing takes place on gestures in my code, I think I will have to switch on to some other alternative. I was wanting to ask if Core Image provides all the functionalities that can be performed using Core Graphics, so that I may use GPU Processing capability. If not, what could be the best alternative so that I can use the same functionalities with a better processing capability.</p>
