/*
 * It may not always be necessary for an application to scan all the
 * way to the edges of the image. By cropping the scan area, you can
 * get most of the benefits of reduced resolution without sacrificing
 * the minimum feature size. Cropping will also not affect image
 * noise, but similar to decreasing the resolution, it does affect the
 * maximum size barcode that can be scanned.
 *
 * For all cases you set the crop rectangle scanCrop property. Note
 * that the rectangle provided to the controller is normalized across
 * image size and rotation. This means that the coordinates range from
 * 0 to 1 and the axes will be arranged such that the x-axis of the
 * crop rectangle corresponds to the major (longer) image axis.
 *
 * Your interface will typically need to indicate the cropped scan
 * area to the user with visual queues. Use the cameraOverlayView to
 * provide this.
 *
 * By default, the ZBarReaderView recognizes a pinch gesture to
 * digitally zoom the preview around the center of the image. This
 * zoom does not affect the resolution of the image, but it does crop
 * the scan region to the visible area. You can also disable the pinch
 * gesture and set the zoom programmatically.
