Here's a simple NeWS program that you can use to grab regions of the
screen and write out raster files, to the file "/tmp/clip".

% Here's a little cut and paste and sketch program that uses the file
% /tmp/clip as its storage. NeWS stores the "clip" as a run-length
% encoded sun raster file (B+W or Color).
% 
% I have used this program to clip stuff for B+W and color raster
% printers, on a Sun with TRANSCRIPT software this is one way to
% print the rasterfile to a LaserWriter:
% 
% /usr/lib/rasfilters/convert.2 /tmp/clip | pssun | lpr
