+.PP

+it anywhere on the line you want.

+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBpnmquantall\fP takes a bunch of Netpbm image files as input, chooses
+\fIncolors\fP colors to best represent all of the images, maps the
+existing colors to the new ones, and \fBoverwrites the input
+files\fP with the new quantized versions.
+.PP
+If you don't want to overwrite your input files, use the
+\fB-ext\fP option.  The output files are then named the same as the
+input files, plus a period and the extension text you specify.
+.PP
+The purpose is this: Let's say you've got a dozen PPMs that you want to
+display on the screen all at the same time.  Your screen can only display 256
+different colors, but the PPMs have a total of a thousand or so different
+colors.  For a single image you solve this problem
+with \fBpnmquant\fP; \fBpnmquantall\fP solves it for multiple images.
+.PP
+Note that another approach to this problem is to pre-select a set
+of colors and then use \fBpnmremap\fP to separately quantize each PPM
+to that set.)
+.PP
+This is a rather simple program that runs \fBpnmcolormap\fP and
+\fBpnmremap\fP.  If you are considering using it in a program of any
+sophistication, you should probably just run those programs directly.
+Even if you are typing it, you may want to do the steps manually because
+it gives you access to the various options of \fBpnmcolormap\fP and
+\fBpnmremap\fP for doing the quantization differently.
+

+.PP
+\fBpnmquantall\fP recognizes the following command line option:
+
+
+.TP
+\fB-ext\fP \fIextension\fP
+Specify an extension for the output files.  By default the input files
+are overwritten.
+
+.PP
+\fBpnmquantall\fP does not recognize the options common to all
+programs based on libnetpbm (See 
+.UR index.html#commonoptions
+ Common Options
+.UE
+\&.)  However, the \fB-version\fP option works.
