Python OpenCV - resizeWindow() Function

Last Updated : 03 Jan, 2023

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:
