I have this python code

I need to can zoom in and zoom out on this image with mouse wheel

I am sure this is question of many people - solve this problem can solve their problem too

import cv2

if __name__ == '__main__' :


 im_dst = cv2.imread('C:/11.jpg')
 cv2.imshow('Image',im_dst)

I could find a way for zoom on normal image window with mouse in python by search , but it could not work on opencv window

i searched 2days on internet but i could not find a correct way (i found a way for old opencv (not cv2)) but it could not work with new opencv

any help is welcomed thanks

# in terminal: pip install mouse
import mouse

if mouse.wheel(1) # Zoom in / mouse wheel up
    # change the image size
if mouse.wheel(-1) # Zoom out / mouse wheel down
    # change the image size
