+.SH NAME
+
+pamdepth - change the depth (color resolution) in a Netpbm image
+
+.UN synopsis
+.SH SYNOPSIS
+
+\fBpamdepth\fP \fInewmaxval\fP [\fInetpbmfile\fP]
+
+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBpamdepth\fP reads a Netpbm image as input, changes its depth (color
+resolution), and writes out the resulting Netpbm image.  I.e. the output has a
+different maxval from the input, but all the same colors (apart from rounding
+error).
+.PP
+Reducing the depth results in some loss of information.
+.PP
+Here is an example of the effect at the image format level: Assume you
+start with an image with maxval 100 and sample values of 50 and 100.  You
+tell \fBpamdepth\fP to change it to depth 150.  The output has maxval
+200 and sample values 75 and 150.
+.PP
+This program works on multi-image streams.
+.PP
+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.
+.PP
+One important use of \fBpamdepth\fP 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 \fInewmaxval\fP less than 256, the
+resulting file should be readable by any program that worked with PNM
+files before April 2000.

+.SH HISTORY
+.PP
+\fBpamdepth\fP was new in Netpbm 10.32 (February 2006).  It replaced
+\fBpnmdepth\fP, by Jef Poskanzer.  \fBpamdepth\fP is backward compatible
+with \fBpnmdepth\fP and adds the ability to process arbitrary PAM images
+and the ability to process multi-image input streams.  \fBpnmdepth\fP
+handled only PNM images and ignored all but the first in any stream.
