SYNOPSIS

9       psblack < input_PostScript_file > output_PostScript_file
10

DESCRIPTION

12       psblack is a filter which reads a PostScript file as input and writes a
13       PostScript file as output.  In the output  file  the  filter  forces  a
14       black background and scales the intensity values (values with R=G=B) so
15       that any intensity greater than or equal to  .8  is  mapped  to  white.
16       This filter works only on PostScript files produced by ctrans - the CGM
17       translator in the NCAR Graphics software.
