- 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.
