pnmdepth

pnmdepth(1)                                                   General Commands Manual                                                  pnmdepth(1)

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  max-
       val of 31, not 32.

       One  important  use  of pnmdepth is to convert a new format 2-byte-per-sample PNM file to the older 1-byte-per-sample format.  Before April
       2000, essentially all raw (binary) format PNM files had a maxval less than 256 and one byte per sample, and many programs may rely on that.
       If  you  specify  a  newmaxval  less than 256, the resulting file should be readable by any program that worked with PNM files before April
       2000.
