pnmcat - concatenate portable anymaps

pnmcat [ -white | -black ]

R -leftright | -lr [ -jtop | -jbottom ] pnmfile pnmfile ...

pnmcat [ -white | -black ]

R -topbottom | -tb [ -jleft | -jright ] pnmfile pnmfile ...

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.

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.
