       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.
