Pgmagick shear() method – Python
  • Last Updated : 26 May, 2020

The shear() function is an inbuilt function in the Pgmagick 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.

Syntax:

shear(x, y)

Parameters: This function accepts two parameters as mentioned above and described below:

  • 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 Pgmagick object with image added.

Input Image:






from pgmagick import Image, DrawableCircle, DrawableText
from pgmagick import Geometry, Color
  
# draw the image of dimension 600 * 600
img = Image('input.png')
  
# invoke shear function with width as 30, height as 40 and Percentage as True
img.shear(30, 40)
  
# invoke write function along with filename
img.write('2_a.png')

Output:

Example 2:




# import library
from pgmagick import Image, DrawableCircle, DrawableText
from pgmagick import Geometry, Color
  
# Draw image of dimension 600 * 600 having background green
im = Image(Geometry(600, 600), Color("# 32CD32"))
  
# invoke DrawableCircle() function
circle = DrawableCircle(100, 100, 300, 20)
  
# invoke draw() function
im.draw(circle)
  
# set font size to 40px
im.fontPointsize(40)
  
# invoke DrawableText() function
text = DrawableText(250, 450, "GeeksForGeeks")
  
# invoke draw() function
im.draw(text)
  
# invoke shave function with width as 40 and height as 50
im.shear(40, 50)
  
# invoke write function along with filename
im.write('1_b.png')
