Simple work around for picking image and converting to b64

image-picker.js

      /* Initialize options */
      var options = {
          quality: 50,
          destinationType: Camera.DestinationType.DATA_URL,
          sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
          allowEdit: true,
          encodingType: Camera.EncodingType.JPEG,
          targetWidth: 800,
          targetHeight: 800,
          popoverOptions: CameraPopoverOptions,
          saveToPhotoAlbum: false
      };
      /* Fire up camera */
      $cordovaCamera.getPicture(options).then(function(imageData) {
          $scope.rawImage = "data:image/jpeg;base64," + imageData;
      }, function(err) {
          /* Encounter error */
          console.log(err);
      });
