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。

原图:

示例 1:

Python3
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')

输出:
