Create a white image using NumPy in Python

Let us see how to create a white image using NumPy and cv2. A white image has all its pixels as 255.

Method 1: Using np.full() method : 

Python3

# importing the libraries
import cv2
import numpy as np

# creating an array using np.full
# 255 is code for white color
array_created = np.full((500, 500, 3),
                        255, dtype = np.uint8)

# displaying the image
cv2.imshow("image", array_created)

Output:

Method 2: By creating an array using np.zeroes() : 

Python3

# importing the modules
import numpy as np
import cv2

# creating array using np.zeroes()
array = np.zeros([500, 500, 3],
                 dtype = np.uint8)

# setting RGB color values as 255,255,255
array[:, :] = [255, 255, 255]

# displaying the image
cv2.imshow("image", array)

Output:
