title: Saving a PNG (or good quality JPG) image to the Photos Library
body: <p><strong>Scenario</strong>
  Saving a 320x480 view as an image in the user's saved photos album.</p>
  
  <p><strong>Problem</strong>
  Always saves a 800x?, low quality JPG.</p>
  
  <p>Using the normal renderInContext/UIImageWriteToSavedPhotosAlbum method to save a view to the library. I've tried converting the UIImage to a PNGRepresentation then using that data to make a new UIImage - it still just saves a JPG in the library.</p>
  
  <p>I could possibly solve this problem by upsizing my view to 800px tall then take the "screenshot" - but that's going to be a lot of work.</p>
  
  <p>Has anyone been able to solve this low-quality saved image problem? I've seen threads all over about it but the always die off without any solid ideas. </p>
  
  <p><em>Thanks,
  Ian</em></p>
