Python PIL | blend() method

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. PIL.Image.blend() method creates a new image by interpolating between two input images, using a constant alpha.

Syntax: PIL.Image.blend(image1, image2, alpha). 
Parameter: 
image1: first image 
image2: second image, must have the same mode and size as the first image.
alpha: The interpolation alpha factor. If alpha is 0.0, a copy of the first image is returned. If alpha is 1.0, a copy of the second image is returned. There are no restrictions on the alpha value. If necessary, the result is clipped to fit into the allowed output range.

Image2:

Python3

# Importing Image module from PIL package
from PIL import Image

# creating a image1 object and convert it to mode 'P'
im1 = Image.open(r"C:\Users\sadow984\Desktop\i2.PNG").convert('L')

# creating a image2 object and convert it to mode 'P'
im2 = Image.open(r"C:\Users\sadow984\Desktop\c2.PNG").convert('L')

# alpha is 0.0, a copy of the first image is returned
im3 = Image.blend(im1, im2, 0.0)

# to show specified image
im3.show()

Output:
