Python PIL | ImageChops.subtract() method

  • Last Updated : 29 Jun, 2019
PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageChops module contains a number of arithmetical image operations, called channel operations (“chops”). These can be used for various purposes, including special effects, image compositions, algorithmic painting, and more.

PIL.ImageChops.subtract() method subtracts two images, dividing the result by scale and adding the offset. If omitted, scale defaults to 1.0, and offset to 0.0. At least one of the images must have mode “1”.

Syntax: PIL.ImageChops.subtract(image1, image2, scale=1.0, offset=0)

Parameters:
image1: first image
image2: second image
scale: numeric value
offset: numeric value

Return Type: Image

Image1:

Image2:




# Importing Image and ImageChops module from PIL package  
from PIL import Image, ImageChops 
    
# creating a image1 object 
im1 = Image.open(r"C:\Users\sadow984\Desktop\a2.PNG"
    
# creating a image2 object 
im2 = Image.open(r"C:\Users\sadow984\Desktop\x5.PNG"
    
# applying subtract method 
im3 = ImageChops.add(im1, im2, scale = 1.0, offset = 2
    
im3.show() 

Output:
