title: Barcode reader in sencha-touch
body: <p>I have been asked to take an image of a bar code, and read its content.</p>
  
  <p>So far, i know how to access the camera and take the image. I don't know how to read the barcode. Can someone show me an example/tutorial where i could do this easily. Or if there is a javascript library where i could make use of ?</p>
  
  <p>2.) Since Sencha-Touch is Javasript, and if the barcodr reader library is also in javascript, I could identify the barcode from the Phone it self  (without having to upload the image to the server, for the server to read the content)?</p>
  
  <p>i found this in the net, <a href="https://stackoverflow.com/questions/6869445/reading-barcode-from-an-image-using-javascript">but not sure how to use it</a> </p>
