Color postscript from screendump

[Swaminathan Ravikumar]

How can I get color postscript files from the screendump output.  I do the
following to get monochrome postscript files.

	screendump | rasfilter8to1 | pssun > postscript.out

"pssun" is the command to convert a Sun raster-format file to a postscript
file.

"rasfilter8to1" converts 8 bit deep pixels to 1 bit deep pixels.

Any help would be appreciated.
