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.
