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.
