Image.point() method in Python PIL

Let’s learn image.point() method of PIL in Python with simple examples.

Below I have written a program that opens the image that we are using.

#for opening the image we are using
from PIL import Image
im = Image.open("img2.jpg")
im.show()

Output:

 

Now through examples, we are gonna see how this Image.point( ) method works.

First Example:

from PIL import Image  
  
im = Image.open("img2.jpg")  
  
# using point function 
threshold = 120  
im = im.point(lambda p: p > threshold and 255) 
im.show()

Output:

 

Second Example:

from PIL import Image  
  
im = Image.open("img2.jpg")  
  
# using point function 
threshold = 191  
im = im.point(lambda p: p > threshold and 255) 
im.show()

Output:

 

Third Example:

from PIL import Image  
    
im = Image.open("img2.jpg")  
  
# using point function 
threshold = 90 
im = im.point(lambda p:p > threshold and 250 )
im.show()

Output:

 

Since in each program the threshold value is different, therefore they have different outputs. Hence, you can vary the threshold value as your wish and can get the desired output.
