Python PIL | putpixel() method

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The PixelAccess class provides read and write access to PIL.Image data at a pixel level.
Accessing individual pixels is fairly slow. If you are looping over all of the pixels in an image, there is likely a faster way using other parts of the Pillow API.

putpixel() Modifies the pixel at x, y. The color is given as a single numerical value for single band images, and a tuple for multi-band images

Syntax: putpixel(self, xy, color)

Parameters:

xy :The pixel coordinate, given as (x, y)
value: – The pixel value.

Returns: An Image with pixel .

Image Used:

# Importing Image from PIL package
from PIL import Image

# creating a image object
image = Image.open(r'C:\Users\System-Pc\Desktop\python.png')

width, height = image.size

for x in range(height):
    image.putpixel( (x, x), (0, 0, 0, 255) )

image.show()

Output:

Another example:Here we change the color parameter.
