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 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 option 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.
