title: Detecting (Multiple) QR Codes with ZXing
body: <p>I'm writing a small java program that will detect a QR code in a given image, then decode it and print out the result (assuming the QR code contains a string). Ideally, I'd like to be able to extend this to detect and decode multiple QR codes from a single image.</p>
  
  <p>A quick google led me to the <a href="http://code.google.com/p/zxing/" rel="nofollow">zxing</a> library, but all of the documentation and tutorials I've found so far relate specifically to Android. Are there any docs/tutorials out there that will help me, or do I need to trudge through the <a href="http://zxing.org/w/docs/javadoc/index.html" rel="nofollow">project api</a>?</p>
