This should get you going. If it doesn't work it will
still direct you to the relevant chapters in the tutorial.

def draw_line (image):
# image is a PIL Image ( <class Image.Image at ...> )
# Define your colors
WHITE = ~0 # Probably white for all modes.
LINE_COLOR = 0 # define
# Find end points
points = []
pixels = image.load () # Fast pixel access
for y in range (image.size [1]):
for x in range (image.size [0]):
if pixels [x, y] != WHITE
points.append ((x, y))
# Join end points
draw = ImageDraw.Draw (image)
draw.line (points, fill = LINE_COLOR)
