Hi All, For the last few weeks I've been tearing my hair out trying to get a tiling mechanism working on an iPhone. I need to scale and crop images of about 150mb so that they can be saved as tiles that will be requested by a scroll view, allowing the user to see the image in high resolution. The problem is that these images are really...
