Python OpenCV - resizeWindow() Function Last Updated : 03 Jan, 2023 Comments Improve Suggest changes Like Article Like 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/videowidth: 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: Comment More infoAdvertise with us Next Article Python OpenCV - resizeWindow() Function vibhutijain99 Follow Improve Article Tags : Python OpenCV Python-OpenCV Practice Tags : python Similar Reads Python OpenCV - setWindowTitle() Function Python OpenCV setWindowTitle() method used for giving the title of the windows. It takes 2 parameters that are windows name and the title that needs to be given. Both the parameters are expected to be of string type.

Do you want to display images and videos using a simplified interface through an OpenCV code? Then, you must check out the OpenCV startWindowsThread() function, which lets you use the high GUI windows, i.e., a simpl 3 min read Python OpenCV - selectroi() Function In this article, we are going to see an interesting application of the OpenCV library, which is selectROI(). With this method, we can select a range of interest in an image manually by selecting the area on the image.

Scaling comes in handy in many image processing as well as machine learning applications. It helps in reducing the number of pixels from an image and that has several advantages e.g. It can reduce the time of training of a neural network as the more th 3 min read Python OpenCV - moveWindow() Function When we show the image using the imshow() function output window will open at the center or default position of a computer screen. Even if there are multiple image windows all windows will be displayed at the same position and we have to move windows manually. If we want to show image windows at a s 2 min read Python OpenCV - namedWindow() Function Python OpenCV namedWindow() method is used to create a window with a suitable name and size to display images and videos on the screen. The image by default is displayed in its original size, so we may need to resize the image for it to fit our screen. Created windows are referred by their names and 3 min read Like
