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 pa-
       mundice for that.

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

       The  program  can generate large	temporary files.  By default, these go
       in directory /tmp, but you can usse the TMPDIR environment variable  to
       have them somewhere else.

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  ra-
	      tio.  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 quantization (to the number of colors specified by -col-
	      ors).  Quantization is on	by default but you can disable it with
	      -noquant.

       -noquant
	      See -quant.
