Wand shear() function – Python
  • Last Updated : 04 May, 2020

The shear() function is an inbuilt function in the Python Wand ImageMagick library which is used to slide one edge of an image along the X or Y axis to create a parallelogram. The X-direction shear slides an edge along the X-axis, while a Y direction shear slides an edge along the Y-axis. The shear angle is used to set shear of the image.


shear(background, x, y)

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

  • background: This parameter stores the background color.
  • x: This parameter is used to set degrees to x-shear of the image.
  • y: This parameter is used to set degrees to y-shear of the image.

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 shear:
        # Invoke shear function 
        shear.shear('Red', 20, 30)
        # Save the image ='shear1.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 shear function method
        pic.shear('Green', 30, 45)
        # Save the image ='shear2.jpg')
