.transpose()

In Pillow, the .transpose() method is used to flip or rotate an image in 90-degree steps.

Syntax

Image.transpose(method)

• Image: Refers to the image object to which the transpose operations are to be applied.
• method: Specifies the type of transpose operation to perform. It can take one of the following values:
  • Image.FLIP_LEFT_RIGHT: Flips the image horizontally (left to right).
  • Image.FLIP_TOP_BOTTOM: Flips the image vertically (top to bottom).
  • Image.ROTATE_90: Rotates the image by 90 degrees anticlockwise.
  • Image.ROTATE_180: Rotates the image by 180 degrees.
  • Image.ROTATE_270: Rotates the image by 270 degrees anticlockwise.
  • Image.TRANSPOSE: Transposes the image, which swaps the image’s rows and columns.
  • Image.TRANSVERSE: Performs a diagonal flip from the bottom-left to the top-right of the image.

Example

The following example demonstrates the use of the .transpose() method:

import PIL
from PIL import Image

# Read the image
im = Image.open("bird-thumbnail.jpg")

# Display the original image
im.show()

# Flip image
out = im.transpose(PIL.Image.FLIP_LEFT_RIGHT)

# Display the flipped image
out.show()
