shade(gray, azimuth, elevation)
Parameters: This function accepts three parameters as mentioned above and defined below:
- gray: This is a boolean parameter which stores the isolation effect. Default is ‘False’.
- azimuth: This parameter stores the angle from x-axis.
- elevation: This parameter stores the amount of angle from the z-axis.

示例 1:
Python3
# 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 shade:
# Invoke shade function
shade.shade(True, 10, 15)
# Save the image
shade.save(filename ='shade1.jpg')
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 shade function method
pic.shade(False, 15, 15)
# Save the image
pic.save(filename ='shade2.jpg')
输出:
