I am trying to dump an RS6000/320 GRASS Display Window to a postscript
rpinter.
I use the command:
xwd -bitmap | xpr -device ps | lpr -P<printername>
and this prints the xterm border with a blank interior.
Presumably, I need some way of converting the colour xwd dump
to greyscale.
Any ideas much appreciated.
