OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2.imwrite() method is used to save an image to any storage device. This will save the image according to the specified format in current working directory.

Syntax: cv2.imwrite(filename, image)

Parameters:
filename: A string representing the file name. The filename must include image format like .jpg, .png, etc.
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 path
image_path = r'C:\Users\Rajnish\Desktop\GeeksforGeeks\geeks.png'
  
# Image directory
directory = r'C:\Users\Rajnish\Desktop\GeeksforGeeks'
  
# Using cv2.imread() method
# to read the image
img = cv2.imread(image_path)
  
# Change the current directory 
# to specified directory 
os.chdir(directory)
  
# List files and directories  
# in 'C:/Users/Rajnish/Desktop/GeeksforGeeks'  
print("Before saving image:")  
print(os.listdir(directory))  
  
# Filename
filename = 'savedImage.jpg'
  
# Using cv2.imwrite() method
# Saving the image
cv2.imwrite(filename, img)
  
# List files and directories  
# in 'C:/Users / Rajnish / Desktop / GeeksforGeeks'  
print("After saving image:")  
print(os.listdir(directory))
  
print('Successfully saved')

Output:

Before saving image:
['geeks.png']
After saving image:
['geeks.png', 'savedImage.jpg']
