138       -shared-memory, -usePixmap, or -title.
139
140       By  default, the image format of `file' is determined by its magic num‐
141       ber.  To specify a particular image format, precede the  filename  with
142       an  image  format name and a colon (i.e. ps:image) or specify the image
143       type as the filename suffix (i.e. image.ps).  Specify 'file' as '-' for
144       standard input or output.
145
146       Buttons:
147         1    press to map or unmap the Command widget
148         2    press and drag to magnify a region of an image
149         3    press to load an image from a visual image directory

NOTE

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