  -debug events display copious debugging information
  -help print program options
  -log format format of debugging information
  -list type print a list of supported option arguments
  -version print version information 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

NOTE
The display program defaults to the X screen resolution. To display vector formats at their intended size, override the default resolution:
