    # seed_threshold controls the maximum allowed difference between
    # the initial pixel and any filled pixels. It's important to
    # set this such that flood fill doesn't fill the whole image.

    # floating_threshold controls the maximum allowed difference
    # between any two pixels. This can easily fill the whole image
    # with even a very low threshold.

    # flood_fill will fill pixels that both thresholds.

    # You can invert what gets filled with "invert" and clear
    # everything but the filled area with "clear_background".
