範例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 sharpen:
# Invoke sharpen function with radis 50 and sigma 40
sharpen.sharpen(50, 40)
# Save the image
sharpen.save(filename ='sharpen1.jpg')

範例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 sharpen function method with radius 40 and sigma 30
pic.sharpen(40, 30)
# Save the image
pic.save(filename ='sharpen2.jpg')
