Wand noise() function - Python Last Updated : 04 Oct, 2021 Comments Improve Suggest changes Like Article Like Report The noise() function is an inbuilt function in the Python Wand ImageMagick library which is used to add noise to the image. Syntax: noise(noise_type, attenuate, channel) Parameters: This function accepts three parameters as mentioned above and defined below: noise_type: This parameter is used to store the noise type. Some of the available noise types are 'undefined', 'uniform', 'gaussian', 'multiplicative_gaussian', 'impulse', 'laplacian', 'poisson', 'random'.attenuate: This parameter stores the rate of distribution.channel: This parameter stores the channel type as "green", "yellow", "red" etc. 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 noise: # Invoke noise function with Channel "green" and noise poisson noise.noise("poisson", 2, "green") # Save the image noise.save(filename ='noise1.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 noise function with channel "yellow" and noise as impulse pic.noise("impulse", 3, "yellow") # Save the image pic.save(filename ='noise2.jpg') Output: Comment More infoAdvertise with us Next Article Wand noise() function - Python sarthak_ishu11 Follow Improve Article Tags : Python Image-Processing Python-wand Practice Tags : python Similar Reads Wand mode() function - Python The mode() function is an inbuilt function in the Python Wand ImageMagick library which is used to replace each pixel with the mathematical mode of the neighboring colors.

To manipulate an image first of all we need to read image in Python. Parameters : Parameter Input Type Description image Image make exact copy of image blob bytes o 2 min read Wand level() function in Python level() function controls the black and white boundaries of an image. Similar to the gamma() method, mid-point levels can be adjusted with the gamma keyword argument. The black and white point arguments are expecting values between 0.0 & 1.0 which represent percentages.
