Prerequisites: Pillow
Python Pillow or PIL is the Python library that provides image editing and manipulating features. The Image Module in it provides a number of functions to flip and rotate images. image.transpose() is the function used to rotate and flip images with necessary keywords as parameters.
Syntax:
image.transpose(appropriate keyword)
In the examples given below, we will be exploring all possible rotations using an appropriate keyword.
Image used:
Flipping Images
- Anticlockwise: To flip an image in anti-clockwise direction the keyword that needs to be passed is Image.TRANSPOSE.
Syntax:
img.transpose(Image.TRANSPOSE)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
flip_img = img.transpose(Image.TRANSPOSE)
flip_img.show()
|
Output :
Clockwise: To flip an image in the clockwise direction the keyword that needs to be passed is Image.TRANSVERSE.
Syntax:
img.transpose(Image.TRANSVERSE)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
flip_img = img.transpose(Image.TRANSVERSE)
flip_img.show()
|
Output :
Horizontal Flip: For horizontal flip, pass Image.FLIP_LEFT_RIGHT as the keyword.
Syntax :
img.transpose(Image.FLIP_LEFT_RIGHT)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
flip_img = img.transpose(Image.FLIP_LEFT_RIGHT)
flip_img.show()
|
Output :
Vertical flip: To flip vertically pass image.FLIP_TOP_BOTTOM as keyword
Syntax:
img.transpose(Image.FLIP_TOP_BOTTOM)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
flip_img = img.transpose(Image.FLIP_TOP_BOTTOM)
flip_img.show()
|
Output :
Rotating Images
Image rotation is done by specific angles and for that again specific keywords need to passed as discussed below:
Rotate by 90 degrees: The keyword used for this is Image.ROTATE_90
Syntax :
img.transpose(Image.ROTATE_90)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
rot_img = img.transpose(Image.ROTATE_90)
rot_img.show()
|
Output :
Rotate by 180 degrees: To rotate by 180 degrees the keyword used is Image.ROTATE_180
Syntax :
img.transpose(Image.ROTATE_180)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
rot_img = img.transpose(Image.ROTATE_180)
rot_img.show()
|
Output:
Rotate by 270 degrees: To rotate by 270 degrees the keyword used is Image.ROTATE_270
Syntax :
img.transpose(Image.ROTATE_270)
Example:
Python
from PIL import Image
img = Image. open ( 'geek.jpg' )
rot_img = img.transpose(Image.ROTATE_270)
rot_img.show()
|
