Python Imaging Library

Pillow offers several standard procedures for image manipulation. These include:

• per-pixel manipulations,
• masking and transparency handling,
• image filtering, such as blurring, contouring, smoothing, or edge finding,
• image enhancing, such as sharpening, adjusting brightness, contrast or color,
• adding text to images and much more.

Some of the file formats supported are PPM, PNG, JPEG, GIF, TIFF, and BMP. It is also possible to create new file decoders to expand the library of file formats accessible.[7]

This example loads an image from the file system, blurs it, and shows both the original and the blurred image on the screen:

from PIL import Image, ImageFilter  # Import classes from the library.

original_image = Image.open("file.ppm") # Load an image from the file system.
blurred_image = original_image.filter(ImageFilter.BLUR) # Blur the image.

# Display both images.
original_image.show() 
blurred_image.show()

This example loads and rotates an image by 180 degrees:

from PIL import Image # Import Image class from the library.

image = Image.open("file.jpg") # Load the image.
rotated_image = image.rotate(180) # Rotate the image by 180 degrees.
rotated_image.save("file_rotated.jpg") # Save the rotated image.

This example loads and crops an image:

from PIL import Image  # Import Image class from library.

image = Image.open("example.jpg")  # Load image.
cropped_image = image.crop((100, 100, 250, 250))  # Crop the image.
cropped_image.save("example_cropped.jpg")  # Save the image.
