`skimage.draw.draw:bezier_curve`

source: /dev/scikit-image/src/skimage/draw/draw.py :717

Signature

   def     bezier_curve (    r0    ,    c0    ,    r1    ,    c1    ,    r2    ,    c2    ,    weight    ,    shape    =  None     )

Summary

Generate Bezier curve coordinates.

Parameters

r0, c0 : int: Coordinates of the first control point.
r1, c1 : int: Coordinates of the middle control point.
r2, c2 : int: Coordinates of the last control point.
weight : double: Middle control point weight, it describes the line tension.
shape : tuple, optional: Image shape which is used to determine the maximum extent of output pixel coordinates. This is useful for curves that exceed the image size. If None, the full extent of the curve is used.

Returns

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

Notes

The algorithm is the rational quadratic algorithm presented in reference ^[1].

Examples

import numpy as np
from skimage.draw import bezier_curve
img = np.zeros((10, 10), dtype=np.uint8)
rr, cc = bezier_curve(1, 5, 5, -2, 8, 8, 2)
img[rr, cc] = 1
