It chooses <I>ncolors</I> +colors to best represent the image, maps the existing colors +to the new ones, and writes a PNM image as output. + +<P>This program is simply a combination of <B>pnmcolormap</B> and +<B>pnmremap</B>, where the colors of the input are remapped using a +color map which is generated from the colors in that same input. The +options have the same meaning as in those programs. See their +documentation to understand <B>pnmquant</B>. + +<P>It is much faster to call <B>pnmcolormap</B> and <B>pnmremap</B> +directly than to run <B>pnmquant</B>. You save the overhead of the +Perl interpreter and creating two extra processes. <B>pnmquant</B> is +just a convenience. + +<p><b>pnmquant</b> did not exist before Netpbm 9.21 (January 2001). +Before that, <b>ppmquant</b> did the same thing, but only on PPM +images. <b>ppmquant</b> continues to exist, but is only a front end +(for name compatibility) to <b>pnmquant</b>. + +<A NAME="lbAE"> </A> +<H2>SEE ALSO</H2> + +<B><A HREF="pnmcolormap.html">pnmcolormap</A></B>, +<B><A HREF="pnmremap.html">pnmremap</A></B>, +<B><A HREF="ppmquantall.html">ppmquantall</A></B>, +<B><A HREF="pamdepth.html">pamdepth</A></B>, +<B><A HREF="ppmdither.html">ppmdither</A></B>, +<B><A HREF="ppmquant.html">ppmquant</A></B>, +<B><A HREF="pnm.html">pnm</A></B> + +<HR> +<A NAME="index"> </A> +<H2>Table Of Contents</H2> +<UL> +<LI><A HREF="#lbAB">NAME</A> +<LI><A HREF="#lbAC">SYNOPSIS</A> +<LI><A HREF="#lbAD">DESCRIPTION</A> +<LI><A HREF="#lbAE">SEE ALSO</A> +</UL> +</BODY> +</HTML> |
