cv2: How to resize window

Date: 2019-08-26 | python | opencv | cv2 | window | tutorial | image |


I'm using Python and the library cv2 (opencv-python) to display an image in a window but my image is super big and going off the screen. How do I resize my window so the image stays on the screen without distorting it?


Here's an example:

window_width = 600
window_height = 600

cv2.namedWindow("my_window_name", cv2.WINDOW_NORMAL)
cv2.resizeWindow("my_window_name", window_width, window_height)
cv2.imshow("my_window_name", image_to_show)

Basically we're creating a namedWindow which allows us to identify and modify that window later. We then mutate it with resizeWindow and show our image in it with imshow.

did this help?
