Wand splice()函数– Python

splice()函数是Python Wand ImageMagick 库中的一个内置函数，用于通过在 (x, y) 偏移坐标处拼接一个宽 x 高的矩形来分割图像。插入的空间将替换为可用的背景颜色。

Syntax:

Parameters: This function accepts four parameters as mentioned above and defined below: 
 

• width: This parameter stores the width of the rectangle.
• height: This parameter stores the height of the rectangle.
• x: This parameter stores the offset on the x-axis.
• y: This parameter stores the offset on the y-axis.

Return Value: This function returns the Wand ImageMagick object.

示例 1：

Python3

splice(width, height, x, y)

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 splice:
        # Invoke splice function with height as 20, width as 20, x as 10, y as 10
        splice.splice(20, 20, 10, 10)
        # Save the image
        splice.save(filename ='splice1.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 splice function with height as 10, width as 10, x as 15, y as 20
        pic.splice(10, 10, 15, 20)
        # Save the image 
        pic.save(filename ='splice2.jpg')

输出：
