ppmdim(1)						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 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.
