display - displays an image or image sequence on any X server.

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
