NAME

       pnmcat - concatenate portable anymaps

SYNOPSIS

       pnmcat  [-white|-black] -leftright|-lr [-jtop|-jbottom] pnmfile pnmfile
       ...
       pnmcat [-white|-black] -topbottom|-tb [-jleft|-jright] pnmfile  pnmfile
       ...

DESCRIPTION

       Reads  portable  anymaps  as  input.   Concatenates them either left to
       right or top to bottom, and produces a portable anymap as output.

       pamdice splits an image up into smaller ones.

       pnmtile concatenates a single input image to itself repeatedly.

OPTIONS

       If the anymaps are not all the same height (left-right) or width  (top-
       bottom),  the  smaller  ones have to be justified with the largest.  By
       default, they get centered, but you can specify one side or  the  other
       with  one  of  the  -j*  flags.   So, -topbottom -jleft would stack the
       anymaps on top of each other, flush with the left edge.

       The -white and -black flags specify what color to use to  fill  in  the
       extra  space  when  doing this justification.  If neither is specified,
       the program makes a guess.

       All flags can be abbreviated to their shortest unique prefix.
