NAME¶
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.
