       In addition to those listed above, you can specify these standard X
       resources as command line options:  -background, -bordercolor,
       -borderwidth, -font, -foreground, -iconGeometry, -iconic, -mattecolor,
       -name, -shared-memory, -usePixmap, or -title.

       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.

       Buttons:
         1    press to map or unmap the Command widget
         2    press and drag to magnify a region of an image
         3    press to load an image from a visual image directory
