title: Zxing Datamatrix code scanning
body: <p>I am using the zxing datamatrix code scanner in iOS, and there seems to be a bug that makes it so that the code must be in the exact center of the screen in order to read.  As I slide the code closer to the center, it will scan somewhere very close to the exact center of the screen.</p>
  
  <p>For my app's purposes, the datamatrix code might be in the center, but also might be anywhere else in the visible part of the image.  </p>
  
  <p>Can anyone explain this?  Has anyone fixed this? For reference, zxing can scan qr codes anywhere in the visible image.</p>
  
  <p>This will scan:</p>

  <p>This will not scan...</p>
