OpenCV: Auomatic resize of the window to the image displayed

问题

Is there a way to force the window displayed by OpenCV (cv2.imshow())when displaying an image to fit to the width and height of the image without the need to resize by the mouse it for that ?

回答1:

You need to pass CV_WINDOW_AUTOSIZE when creating the namedWindow (or WINDOW_AUTOSIZE if you import cv2 instead of cv)

Here is an example:

cv2.namedWindow("window", cv2.WINDOW_AUTOSIZE) 
# or cv.namedWindow("window",cv.CV_WINDOW_AUTOSIZE)
cv2.imshow("window", yourimage)
