title: How to scale down a UIImage and make it crispy / sharp at the same time instead of blurry?
body: <p>I need to scale down an image, but in a sharp way. In Photoshop for example there are the image size reduction options "Bicubic Smoother" (blurry) and "Bicubic Sharper".</p>
  
  <p>Is this image downscaling algorithm open sourced or documented somewhere or does the SDK offer methods to do this?</p>
