  By default, the image format of 'file' is determined by its magic
  number.  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.
