NAME
       ppmdim - dim a PPM image


SYNOPSIS
       ppmdim dimfactor [ppmfile]


DESCRIPTION
       This program is part of Netpbm(1).

       This   program	is   largely   obsoleted  by  the  more	 general  pam-
       func(1)(usethe-multiplier option).  ppmdim remains for backward compat-
       ibility	and  also  because  its	 use of integer arithmetic may make it
       faster.

       ppmdim reads a PPM image input. Diminishes its brightness by the speci-
       fied  dimfactor.	  The  dimfactor  may  be in the range from 0.0 (total
       blackness, deep night, nada, null, nothing) to 1.0 (original  picture's
       brightness).
