Would anybody out there happen to have a program that displays shaded halftone
output on a Sun-2 workstation display?  My data file is of the following format
1. A single line of text specifying resolution (ie: 420,320) followed by a 
   newline.
2. All the bytes of the image, in row order.  8 bits (256 grey levels) per
   pixel.

I would like a program that would generate a halftone from this image and 
display it on a Sun-2 monochrome display (1 bit).  The quality of the image is
not important...I need it to preview images before spending all the time to
send them to a postscript printer for high quality output.

Thanks
Greg Corson
