Wand spread() function – Python
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 = '../w3wiki.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 ), 'w3wiki !' ) # 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' ) |
