Wand rotate() function – Python

  • Last Updated : 04 May, 2020

The rotate() function is an inbuilt function in the Python Wand ImageMagick library which is used to rotates the image right. It takes a background color for which rotation is not available.

Syntax:

rotate(degree, background, reset_coords)

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

  • degree: This parameter stores the degree of rotation.
  • background: This parameter stores the background color for the portion which has no rotation portion available..
  • reset_coords: This is a boolean parameter which states after the rotation, the coordinate frame will be relocated to the upper-left corner of the new image. By default is True.

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 rotate:
        # Invoke rotate function 
        rotate.rotate(45, 'red', True)
        # Save the image
        rotate.save(filename ='rotate1.jpg')

Output:

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
    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 rotate function method
        pic.rotate(50, 'Green', False)
        # Save the image 
        pic.save(filename ='rotate2.jpg')
