PROGRAM:
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.
