Wand swirl()函数– Python

swirl()函数是Python Wand ImageMagick 库中的一个内置函数，用于围绕图像的中心。度数指定漩涡的紧密度。

Syntax: 
 

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.

swirl(degree, method)

Python3

# 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
        swirl.save(filename ='swirl1.jpg')

输出：

示例 2：

Python3

# 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 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')
