DESCRIPTION
This program is part of Netpbm.

pamaddnoise adds the specified noise type to a Netpbm image.
pamaddnoise treats a PPM image as 3 independent planes, not as a plane
of colors in a color space.

HISTORY
pamaddnoise was added to Netpbm in Version 10.29 (August 2005). It
had been distributed by Mike Burns via his own web site before that
(and continued to be so).

Burns' version, and the one in Netpbm 10.29, was called pnmaddnoise
and worked only on PNM images. In Netpbm 10.30, it was converted to
handle PAM images and renamed to pamaddnoise.
