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