How can I draw lines into numpy arrays?

Question

I would like to be able to draw lines into numpy arrays to get off-line features for on-line handwriting recognition. This means I don\'t need the image at all, but I need f

Thanks to Joe Kington for the answer! I was looking for skimage.draw.line_aa.

import scipy.misc
import numpy as np
from skimage.draw import line_aa
img = np.zeros((10, 10), dtype=np.uint8)
rr, cc, val = line_aa(1, 1, 8, 4)
img[rr, cc] = val * 255
scipy.misc.imsave("out.png", img)
