source: /_skimage2/draw/draw.py:360

Signature

def line(r0, c0, r1, c1)

Summary

Generate line pixel coordinates.

Parameters

r0, c0 : int: Starting position (row, column).
r1, c1 : int: End position (row, column).

Returns

rr, cc : (N,) ndarray of int: Indices of pixels that belong to the line. May be used to directly index into an array, e.g. img[rr, cc] = 1.

Notes

Anti-aliased line generator is available with line_aa.

Examples

from skimage.draw import line
img = np.zeros((10, 10), dtype=np.uint8)
rr, cc = line(1, 1, 8, 8)
img[rr, cc] = 1
