PNMCAT

NAME

      pnmcat - concatenate portable anymaps

SYNOPSIS

      pnmcat [-white|-black] -leftright|-lr|-topbottom|-tb 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.  If
      the anymaps are not all the same height (left-right) or width (top-
      bottom), the smaller ones are centered with the edges filled in.  The
      -white and -black flags specify what color to use for this fill -- if
      neither is specified, the program makes a guess.
      All flags can be abbreviated to their shortest unique prefix.

DEMONSTRATION

      Let a.pnm and b.pnm be two portable anymaps.
      The following commands will concatenate then together:
	pnmmerge pnmcat -leftright a.pnm b.pnm >c.pnm
	pnmmerge pnmcat -topbottom a.pnm b.pnm >c.pnm
