Output: 
Example 2: Increase radius value in spread() method.
# Import Image from wand.image module from wand.image import Image   # Read image using Image() function with Image(filename ="koala.jpeg") as img:       # Generate spread image using spread() function     img.spread(radius = 16.0)     img.save(filename ="spreadkoala2.jpg")  |
