These procedures provide help for applications that write sequences of images. seq_init(opts) initializes the naming parameters from the table opts. opts["n"] is the name, opts["f"] is the first number, and opts["c"] is the number of columns for the serial number. save_image(win, x, y, w, h) write the specified area of win using the next name in sequence. There is no check for duplicate names if the numbering wraps around.
