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:
