title: Loading part of big image from disk with Xamarin
body: <p>Is there any way with Xamarin to load only part of an image directly from disk in iOS?</p>
  
  <p>What I need to do is create tiles from potentially huge images (10k x 10k) to be able to display them as tiles. Is there any way of doing this with Xamarin without loading the whole image into memory which crashes the program?</p>
