Type of Current Pixel	Distance d (in pixels) until next non-Black Pixel
	$d\le D_1$	$D_1<d\le D_2$	$d>D_2$
White	Mark all pixels from p to n and jump to n (p←n)	Mark all pixels from p to n and jump to n (p←n)	Stops
Border	Mark all pixels from p to n and jump to n (p←n)	IF White pixels(input(1…N), p…n)) > min_proportion THEN Mark all pixels from p to n and jump to n (p = n) ELSE Stops	Stops
Black	Jump to n (p$\leftarrow$n)	Jump to n (p$\leftarrow$n)	Stops
