The swirl() function is an inbuilt function in the Python Wand ImageMagick library which is used to around the center of the image. The degrees specify the tightness of the swirl.
Syntax:
swirl(degree, method)Parameters: This function accepts two parameters as mentioned above and defined below:
- degree: This parameter stores the degrees in angle between 0 to 360.
- method: This parameter stores the method which controls interpolation of the effected pixels. Some of the available methods are ‘undefined’, ‘average’, ‘average9’, ‘average16’, ‘background’, ‘bilinear’, ‘blend’, ‘catrom’, ‘integer’, ‘mesh’, ‘nearest’, ‘spline’
Return Value: This function returns the Wand ImageMagick object.

Example 1:
Python3
# Import library from Image from wand.image import Image# Import the imagewith Image(filename ='../neveropen.png') as image: # Clone the image in order to process with image.clone() as swirl: # Invoke swirl function with degree as 100 and method ss 'blend' swirl.swirl(100, 'blend') # Save the image swirl.save(filename ='swirl1.jpg') |
Output:
Example 2:
Python3
# Import libraries from the wand from wand.image import Imagefrom wand.drawing import Drawingfrom wand.color import Colorwith Drawing() as draw: # Set Stroke color the circle to black draw.stroke_color = Color('black') # Set Width of the circle to 2 draw.stroke_width = 1 # Set the fill color to 'White (# FFFFFF)' draw.fill_color = Color('white') # Invoke Circle function with center at 50, 50 and radius 25 draw.circle((200, 200), # Center point (100, 100)) # Perimeter point # Set the font style draw.font = '../Helvetica.ttf' # Set the font size draw.font_size = 30 with Image(width = 400, height = 400, background = Color('# 45ff33')) as pic: # Set the text and its location draw.text(int(pic.width / 3), int(pic.height / 2), 'GeeksForGeeks !') # Draw the picture draw(pic) # Invoke swirl function with degree as 150 and method as bilinear pic.swirl(150, 'bilinear') # Save the image pic.save(filename ='swirl2.jpg') |
