Python OpenCV resizeWindow() Function (original) (raw)
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)
`
