Learn how to rotate images using Python’s Pillow library with the rotate() function to adjust angles and expand parameters.
Rotating the image
For a start we will rotate image 180 degrees.
from PIL import Image
my_image = Image.open("C:/Users/pythoneo/Documents/image.jpg")
rotated_image = my_image.rotate(180, expand='True')
rotated_image.show()
The Pillow (PIL) library provides image manipulation capabilities, including the Image.rotate() function for rotating images at any angle.
Use forward slashes (/) in image file paths instead of backslashes ($$ to ensure cross-platform compatibility in Python scripts.
The first parameter of Image.rotate() is the angle (in degrees), specifying the rotation amount in a clockwise direction.
Set the expand parameter to True in Image.rotate() to automatically resize the output image, preventing cropping of rotated corners.
See the example when you rotate image by custom angle. The benefit is that corners of your image fit to the window. This is image rotated 80 angles clockwise.
How to Rotate Images by Custom Angles Using Pillow’s rotate() Function
When rotating images by custom angles (e.g., 80 degrees), the expand=True parameter ensures rotated corners fit within the output window without cropping.
from PIL import Image
my_image = Image.open("C:/Users/pythoneo/Documents/image.jpg")
rotated_image = my_image.rotate(80, expand=True)
rotated_image.show()
Add parameter documentation: rotate(angle, expand=True) rotates counter-clockwise by default; use negative angles for clockwise rotation.
