NAME
       pnmindex - build a visual index of a bunch of anymaps

SYNOPSIS
       pnmindex	 [-size	 N]  [-across  N]  [-colors  N]	 [-black]  [-title  T]
       [-quant|-noquant] pnmfile ...

DESCRIPTION
       pnmindex creates an index image containing thumbnail  (small)  versions
       of a bunch of PNM files you supply.

       pnmindex labels each thumbnail and, optionally, contains a title.

OPTIONS
       -size N
	      The  size	 of  each thumbnail.  The image is scaled to fit maxi‐
	      mally inside a N x N  pixel  box	without	 changing  its	aspect
	      ratio.  Default is 100.

       -across N
	      The number of thumbnails in each row.  Default is 6.

       -colors N
	      The  maximum  number of colors allowed in the overall image.  If
	      it would otherwise have more colors than these,  pnmindex	 quan‐
	      tizes the result.	 The default is 256.

	      However,	this  value is meaningless if you specify the -noquant
	      option.

       -black This controls the color of the padding between the images;  nor‐
	      mally  it's  white  and  the labels are black lettering on white
	      background, but the -black flag reverses this.

       -title title
	      Specifies a title top place at the top of the image.  Default is
	      no title.

       -quant Enables  quanization (to the number of colors specified by -col‐
	      ors ).  Quantization is on by default but	 you  can  disable  it
	      with -noquant.

       -noquant
	      See -quant.
