## NAME

ppmdim - dim a PPM image

## SYNOPSIS

ppmdim dimfactor [ppmfile]

## DESCRIPTION

This program is part of Netpbm.

This program is largely obsoleted by the more general pamfunc (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).

## OPTIONS

There are no command line options defined specifically for ppmdim, but it recognizes the options common to all programs based on libnetpbm (See Common Options.)

## SEE ALSO
