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).
SEE ALSO
ppm(5), pamfunc(1),
