pnmindex


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 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 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 -col-
              ors ).  Quantization is on by default but  you  can  disable  it
              with -noquant.

       -noquant
              See -quant.
