image: It is the image that is to be saved.Return Value: It returns true if image is saved successfully.
Example #1:
# Python program to explain cv2.imwrite() method # importing cv2 import cv2 # importing os module import os # Image pathimage_path = r'C:\Users\Rajnish\Desktop\Lazyroar\Lazyroar.png' # Image directorydirectory = r'C:\Users\Rajnish\Desktop\Lazyroar' # Using cv2.imread() method# to read the imageimg = cv2.imread(image_path) # Change the current directory # to specified directory os.chdir(directory) # List files and directories # in 'C:/Users/Rajnish/Desktop/Lazyroar' print("Before saving image:") print(os.listdir(directory)) # Filenamefilename = 'savedImage.jpg' # Using cv2.imwrite() method# Saving the imagecv2.imwrite(filename, img) # List files and directories # in 'C:/Users / Rajnish / Desktop / Lazyroar' print("After saving image:") print(os.listdir(directory)) print('Successfully saved') |
Output:
Before saving image: ['Lazyroar.png'] After saving image: ['Lazyroar.png', 'savedImage.jpg'] Successfully saved
