title: phonegap-plugin-barcodescanner, type PDF417 bar-codes using ionic
body: <p>I am fairly new to Ionic development and thus far has not run into too many problems. However, I am stuck on trying to get PDF417 type bar-codes to scan (using phonegap-plugin-barcodescanner), despite the documentation suggesting that they are supported via pass the "PDF_417" parameter in the "formats" option. Note: the scanning works on other codes such as QR_CODE, EAN_13 - So the code is mostly right. I don't think that the options list after the error function is being processed.</p>
  
  <pre><code>  $cordovaBarcodeScanner.scan().then(function(imageData) {
  
      $scope.si_data_display = imageData.text;
      console.log("app.js :: .controller - MainCtrl :: scan_barcode :: text : " + imageData.text);
      console.log("app.js :: .controller - MainCtrl :: scan_barcode :: format : " + imageData.format);
      console.log("app.js :: .controller - MainCtrl :: scan_barcode :: cancelled  : " + imageData.cancelled);
  
    }, function(error) {
      //TODO: better error handling...
      alert("Error with BarcodeScanner" + error);
    },
    { //I DONT THINK THIS IS WORKING!
      "preferFrontCamera" : true, // iOS and Android
      "showFlipCameraButton" : true, // iOS and Android
      "prompt" : "zzzzzzzzzzzz", // supported on Android only
      "formats" : "PDF_417", // default: all but PDF_417 and RSS_EXPANDED
    });
  </code></pre>
  
  <p>Any help, suggestion and or pointers will be gratefully received.</p>
  
  <p>Thank you in advance,
