      }
   }, function(error) {
      c.log('Failed to attach new files.', error);
   });
}

// A helper function to handle addFiles results 
function handleMultipleResult(result) {
   c.log('Added multiple attachments.', result);
   if (result.attachments) {
      c.log('Number of new attachments', result.attachments.length);
   }
   if (result.errors) {
      c.log('Number of errors during upload', result.errors.length);

attachment	Cabrillo.Attachment	Describes the attachment to view.
sourceRect	Cabrillo.Rect	Optional. Describes the source rectangle of the image to scale up.

表 : 6. Returns

Type	Description
promise	If successful, an unresolved object, otherwise an error.

// A Cabrillo.Attachment dictionary to view
var attachment = {
    sys_id: '8e99daa3ff133100ba13ffffffffff2d',
    content_type: 'image/jpeg',
    path: '8e99daa3ff133100ba13ffffffffff2d.iix'
};

cabrillo.attachments.viewFile(attachment,
    null,
    null
).then(function() {
    // It worked. Nothing to do here.
}, function(error) {
    console.log('Failed to view file.', error);
});

To scale an image that was tapped into a native image viewer, the viewFile() method accepts optional arguments for the image's rectangle on the page as well as a base64 encoded thumbnail of the image. The thumbnail is scaled into the full size image with an animation.

// Grab image metadata from an image that was tapped
var imageMetadata = imageMetadataFromEvent(event);

// Optional rect of image on page
var imageRect = imageMetadata.rect;

// Optional base64 encoded image to scale up into native viewer
var base64EncodedImage = imageMetadata.base64;

// A Cabrillo.Attachment dictionary to view
var attachment = {
    sys_id: '8e99daa3ff133100ba13ffffffffff2d',
    content_type: 'image/jpeg',
    path: '8e99daa3ff133100ba13ffffffffff2d.iix'
}

cabrillo.attachments.viewFile(attachment,
    imageRect,
    base64EncodedImage
).then(function() {
    // It worked. Nothing to do here.
}, function(error) {
    console.log('Failed to view file.', error);
});
