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.

Example 1:
Python3
# Import library from Image from wand.image import Image # Import the image with Image(filename = '../neveropen.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' ) |
Output:
Example 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 spread function with radius 10 and method as 'blend' pic.spread( 10 , 'blend' ) # Save the image pic.save(filename = 'spread2.jpg' ) |
