Python OpenCV | cv2.imwrite() method
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') |
