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

       -noquant
              See -quant.
