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  maximally  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 quantizes 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; normally 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 speci
	      fied by -colors ).  Quantization is on  by  default
	      but you can disable it with -noquant.

       -noquant
	      See -quant.
