The modulate() function is an inbuilt function in the Python Wand ImageMagick library which is used to changes the brightness, saturation and hue of the image.
 

Syntax: 
 

modulate(brightness, saturation, hue)

Parameters: This function accepts three parameters as mentioned above and defined below: 
 

  • brightness: This parameter is used to store the brightness percentage.
  • saturation: This parameter is used to store the saturation percentage.
  • hue: This parameter is used to store the hue percentage.

Return Value: This function returns the Wand ImageMagick object.

Original Image: 
 

Example 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 modulate:
        # Invoke modulate function with brightness 30 %, saturation 45 %, hue 25 % modulate.modulate(30, 45, 25)
        # Save the image
        modulate.save(filename ='modulate1.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), 'GeeksForGeeks !')
        # Draw the picture
        draw(pic)
        # Invoke modulate function with brightness 40 %, saturation 60 %, hue 75 % pic.modulate(40, 60, 75)
        # Save the image
        pic.save(filename ='modulate2.jpg')


Output:
