NAME

       pnmflip - perform one or more flip operations on a portable anymap

SYNOPSIS

       pnmflip [-leftright|-lr] [-topbottom|-tb] [-transpose|-xy] [-rotate90|-r90|-ccw ] [-rotate270|-r270|-cw ] [-rotate180|-r180] [pnmfile]

DESCRIPTION

       Reads a portable anymap as input.  Performs one or more flip operations, in the order specified, and writes out a portable anymap.

OPTIONS

       The flip operations available are: left for right (-leftright or -lr); top for bottom (-topbottom or -tb); and transposition (-transpose or
       -xy).  In addition, some canned concatenations are available: -rotate90 or -ccw is equivalent to -transpose -topbottom; -rotate270  or  -cw
       is equivalent to -transpose -leftright; and -rotate180 is equivalent to -leftright -topbottom.

       All flags can be abbreviated to their shortest unique prefix.

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.
