Python - shade() function in Wand

shade() function generates a 3d kind of image or creates a 3d effect by simulating a light from an elevated angle. azimuth parameter is used to control the X and Y angle and elevation parameter is used to control the z angle of the image. We can also get final image in grayscale by putting gray parameter as true.
 

Syntax : 
 

wand.image.shade(gray, azimuth, elevation);

Parameters : 
 

Parameter	Input Type	Description
gray	boolean	Isolate the effect on pixel intensity. Default is False.
azimuth	numbers.real	Angle from x-axis.
elevation	number.Real	Amount of pixels from the z-axis.

Example 1: 
 

# import Image from wand.image module
from wand.image import Image

# Read image using Image function
with Image(filename ="koala.jpeg") as img:

    # generating shaded image using shade() function.
    img.shade(gray = True,
              azimuth = 286.0,
              elevation = 45.0)

    img.save(filename ="shadekoala.jpeg")

Output: 
 

Example 2: setting gray as False, increasing azimuth and elevation value.
 

# import Image from wand.image module

from wand.image import Image

with Image(filename ="koala.jpeg") as img:
    # generating shaded image using shade() function.
    img.shade(gray = True,
              azimuth = 298.0,
              elevation = 70.0)

    img.save(filename ="shadekoala_2.jpeg")

Output:
