Wand swirl() function – Python
  • Last Updated : 10 May, 2020

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.


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.

Original Image:

Example 1:

# Import library from Image 
from wand.image import Image
# Import the image
with Image(filename ='../geeksforgeeks.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 ='swirl1.jpg')


Example 2:

# Import libraries from the wand  
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
with Drawing() as draw:
    # Set Stroke color the circle to black
    draw.stroke_color = Color('black')
    # Set Width of the circlw 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, 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
        # Invoke swirl function with degree as 150 and method as bilinear
        pic.swirl(150, 'bilinear')
        # Save the image ='swirl2.jpg')
