ppmdim - dim a portable pixmap down to total blackness
SYNOPSIS
ppmdim dimfactor [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Diminishes its bright
ness by the specified dimfactor down to total blackness.
The dimfactor may be in the range from 0.0 (total black
ness, 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.
