By default, the image format of `file' is determined by its magic num-
ber. To specify a particular image format, precede the filename with
an image format name and a colon (i.e. ps:image) or specify the image
type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for
standard input or output.
