title: Decode JPEG to obtain uncompressed data
body: <p>I want to decode JPEG files and obtain uncompressed decoded output in BMP/RGB format.I am using GNU/Linux, and C/C++.</p>
  
  <p>I had a look at libjpeg, but there seemed not to be any good documentation available.
  So my questions are:</p>
  
  <ol>
  <li>Where is documentation on libjpeg?</li>
  <li>Can you suggest other C-based jpeg-decompression libraries?</li>
  </ol>
