16 This program is largely obsoleted by the more general pamfunc(1) (use
17 the -multiplier option). ppmdim remains for backward compatibility and
18 also because its use of integer arithmetic may make it faster.

20 ppmdim reads a PPM image input and diminishes its brightness by the
21 specified dimfactor. The dimfactor may be in the range from 0.0 (total
22 blackness, deep night, nada, null, nothing) to 1.0 (original picture's
23 brightness).
