NAME
pnmdepth - change the maxval in a portable anymap
SYNOPSIS
pnmdepth
newmaxval
[pnmfile]
DESCRIPTION
Reads a portable anymap as input.
Scales all the pixel values, and writes out the image with the new maxval.
Scaling the colors down to a smaller maxval will result in some loss
of information.
Be careful of off-by-one errors when choosing the new maxval.
For instance, if you want the color values to be five bits wide,
use a maxval of 31, not 32.
