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 pamfunc(1)
        (use the -multiplier option).  ppmdim remains for backward
       compatibility and also because its use of integer arithmetic may make
       it faster.

       ppmdim reads a PPM image input and diminishes its brightness by the
       specified 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).
