title: Google App Engine (So "Pure Python"): Convert PDF to Image
body: <p>In Google App Engine, I need to be able to take an uploaded PDF and convert it to an image (or maybe one day a number of tiled images) for storing and serving back out.  Is there a library that will read PDF files that is also 100% python (so it can be uploaded with my app)?</p>
  
  <p>From what I've gathered so far...</p>
  
  <ul>
  <li><em>PIL</em> does not <strong>read</strong> PDF files, only writes them.</li>
  <li><em>GhostScript</em> is the standard FOSS PDF reader, but I don't believe I'll be able to upload it with my app to GAE since I don't believe it's 100% python.</li>
  </ul>
  
  <p>Is there anything else I might be able to use?  Or maybe even a web service that I can call?)</p>
