psblack — PostScript filter.

Synopsis

psblack < input_PostScript_file > output_PostScript_file

Description

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