pamundice
Combine a grid of Netpbm images into one.
TLDR
Combine the images whose names match the printf-style filename expression. Assume a grid with a specific size
$ pamundice [filename_%1d_%1a.ppm] -across [grid_width] -down [grid_height] > [path/to/output.ppm]
Assume that the tiles overlap horizontally and vertically by the specified amount
$ pamundice [filename_%1d_%1a.ppm] -across [x_value] -down [y_value] -hoverlap [value] -voverlap [value] > [path/to/output.ppm]
Specify the images to be combined through a text file containing one filename per line
$ pamundice -listfile [path/to/file.txt] -across [x_value] -down [y_value] > [path/to/output.ppm]
