RedHat 9 (Linux i386) - man page for ppmdim (redhat section 1)

ppmdim(1)				       General Commands Manual					    ppmdim(1)

NAME
ppmdim - dim a portable pixmap down to total blackness
SYNOPSIS
ppmdim dimfactor [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Diminishes its brightness by the specified dimfactor down to total black- ness. The dimfactor may be in the range from 0.0 (total blackness, deep night, nada, null, nothing) to 1.0 (original picture's brightness). As pnmgamma does not do the brightness correction in the way I wanted it, this small program was written. ppmdim is similar to ppmbrighten , but not exactly the same.
