3. Image linear_gradient

See: https://pillow.readthedocs.io/en/stable/reference/Image.html#PIL.Image.linear_gradient

3.1. Linear_gradient

Use Image.linear_gradient(mode) to generate 256x256 linear gradient from black to white, top to bottom.
Input mode is from [“L”, “P”].
from PIL import Image

im = Image.linear_gradient('L')
im.save("image/Image_linear_gradient.png")
