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

The spread() function is an inbuilt function in the Python Wand ImageMagick library which is used to replace each pixel with the statistic results from neighboring pixel values. The width & height defines the size, or aperture, of the neighboring pixels.

Syntax:

spread(radius, method)

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

  • radius: This parameter stores the radius of the pixel can be displaced from source.
  • method: This parameter stores the available color methods. Some of the available methods are ‘undefined’, ‘average’, ‘average9’, ‘average16’, ‘background’, ‘bilinear’, ‘blend’, ‘catrom’, ‘integer’, ‘mesh’, ‘nearest’, ‘spline’.

Return Value: This function returns the Wand ImageMagick object.

# 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 spread:
        # Invoke spread function with radius 15 and method as 'nearest'
        spread.spread(15, 'nearest')
        # Save the image
        spread.save(filename ='spread1.jpg')

        # Set the text and its location
        draw.text(int(pic.width / 3), int(pic.height / 2), 'GeeksForGeeks !')
        # Draw the picture
        draw(pic)

        pic.spread(10, 'blend')
        # Save the image
