NAME
       pnmindex - build a visual index of a bunch of PNM images

SYNOPSIS
       pnmindex

       [-size=N]

       [-across=N]

       [-colors=N]

       [-black]

       [-title=title]

       [-quant|-noquant]

       pnmfile ...

       You  can  use  the  minimum  unique  abbreviation of the options.  You can use two hyphens
       instead of one.	You can separate an option name from its value with white  space  instead
       of an equals sign.

DESCRIPTION
       This program is part of Netpbm(1)

       pnmindex  creates  an  index image containing thumbnail (small) versions of a bunch of PNM
       files you supply.  (Akin to a photographic 'contact sheet.'

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

       If you just want to concatenate some images together in a grid, use pamundice for that.

       If you want to take apart the image you generated with pnmindex, use pamdice or pamcut.

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 option reverses
	      this.

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

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

       -noquant
	      See -quant.
