title: Faster image processing
body: <p>Can someone suggest me a library that can do simplest operations like scale, crop, rotate without loading image fully into memory?</p>
  
  <p>The situation: I need to scale image down from a very large size, but the scaled down image is still too large to be allocated in memory (if we use standard android tools). Since I only need to upload scaled down version, I thought of scaling it through native library and upload it through FileInputStream.</p>
  
  <p>I've tried to use ImageMagic and it does the job, but performance is very poor (maybe there is a way to speed things up?)</p>
