set-color

set_color

skimage.draw.set_color(img, coords, color, alpha=1) [source]

Set pixel color in the image at the given coordinates.

Coordinates that exceed the shape of the image will be ignored.

Parameters:	img : (M, N, D) ndarray Image coords : tuple of ((P,) ndarray, (P,) ndarray) Row and column coordinates of pixels to be colored. color : (D,) ndarray Color to be assigned to coordinates in the image. alpha : scalar or (N,) ndarray Alpha values used to blend color with image. 0 is transparent, 1 is opaque.
Returns:	img : (M, N, D) ndarray The updated image.
