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...



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.

       pnmindex labels each thumbnail and, optionally, contains a title.

       If you just want to concatenate some images together,  use  pnmcat  for
       that.   If  you want to make a grid of the same image repeated over and
       over, that’s pnmtile.

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




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 option 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.
