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 back-
              ground, 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 -colors ).  Quantization is on by default but  you  can  disable  it  with
              -noquant.

       -noquant
              See -quant.
