Python PIL | putpixel() method

  • Last Updated : 19 Jul, 2019

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.
