Python PIL | blend() method
  • Last Updated : 25 Jun, 2019
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.

Image1:

Image2:






# 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:




# 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 1.0, a copy of the second image is returned
im3 = Image.blend(im1, im2, 0.0)
  
# to show specified image 
im3.show()

Output:
