title: Resizing UIImage and saving
body: <p>I am trying to figure out how I can shrink and save a UIImage, read it back in later, and then convert back to the original size without losing quality. I have managed to do the resizing and saving, but the problem is that if I save it smaller, when I read it back in and expand it, the quality is very poor. Does anyone know how this can be done without losing image quality?</p>
