The magnifying glass only affects the view of the prescanned
image in the preview area and does not affect the scanning process
or the final scanned image.

image larger. Adjusting the size of an image must be done by
scaling it in an image-editing application. Make sure to scan the
image at a sufficiently high resolution when planning to enlarge it, so
there are enough pixels to maintain image integrity after the scaling
process.
