function

`skimage.draw.draw:disk`

source: /dev/scikit-image/src/skimage/draw/draw.py :152

Signature

def disk ( center , radius , * , shape = None )

Summary

Generate coordinates of pixels within circle.

Parameters

center : tuple: Center coordinate of disk.
radius : double: Radius of disk.
shape : tuple, optional: Image shape as a tuple of size 2. Determines the maximum extent of output pixel coordinates. This is useful for disks that exceed the image size. If None, the full extent of the disk is used. The shape might result in negative coordinates and wraparound behaviour.

Returns

rr, cc : ndarray of int: Pixel coordinates of disk. May be used to directly index into an array, e.g. img[rr, cc] = 1.

Examples

import numpy as np
from skimage.draw import disk
shape = (4, 4)
img = np.zeros(shape, dtype=np.uint8)
rr, cc = disk((0, 0), 2, shape=shape)
img[rr, cc] = 1
img
img = np.zeros(shape, dtype=np.uint8)
rr, cc = disk((0, 0), 2, shape=None)
img[rr, cc] = 1
img
img = np.zeros((10, 10), dtype=np.uint8)
rr, cc = disk((4, 4), 5)
img[rr, cc] = 1
