title: Resize and Save NSImage?
body: <p>I have an NSImageView which I get an image for from an NSOpenPanel. That works great.</p>
  
  <p>Now, how can I take that NSImage, half its size and save it as the same format in the same directory as the original as well?</p>
  
  <p>If you can help at all with anything I'd appreciate it, thanks.</p>
