Changing the Image Size
Once an image is scanned or a digital photograph is loaded from the camera, it
is often necessary to modify the size for display on a web page or for printing.
Images can easily be made smaller either by scaling them down or by cutting off
parts of them. Making an image larger is much more problematic. Because of the
nature of pixel graphics, quality is lost when an image is made larger. It is recom-
