Report

resizeWindow() method in Python OpenCV is used to resize window displaying images/videos to a specific size. The specified window size is for images excluding toolbars. This only works for created windows having flags other than CV_WINDOW_AUTOSIZE.

Syntax: cv2.resizeWindow(window_name, width, height)

Parameters:

  • window_name: Name of the window that will display image/video
  • width: New window width (integer type)   
  • height: New window height (integer type)

Return Value: It doesn't return anything

Image used for below examples:

Example 1:

Python3 
# Python program to explain cv2.resizeWindow() method  # Importing cv2 import cv2  # Path path = 'C:/Users/art/OneDrive/Desktop/geeks.png'  # Reading an image in default mode image = cv2.imread(path)  # Naming a window cv2.namedWindow("Resized_Window", cv2.WINDOW_NORMAL)  # Using resizeWindow() cv2.resizeWindow("Resized_Window", 300, 700)  # Displaying the image cv2.imshow("Resized_Window", image) cv2.waitKey(0)

Output:

Example 2:

Python3 
# Python program to explain cv2.resizeWindow() method  # Importing cv2 import cv2  # Path path = 'C:/Users/art/OneDrive/Desktop/geeks.png'  # Reading an image in grayscale mode image = cv2.imread(path, 0)  # Naming a window cv2.namedWindow("Resize", cv2.WINDOW_NORMAL)   # Using resizeWindow() cv2.resizeWindow("Resize", 700, 200)  # Displaying the image cv2.imshow("Resize", image) cv2.waitKey(0)

Output:
