Hi Guys

I have an image with 6000 * 6000 pixels as shown

link of image

When I run the following code

    import cv2
    img = cv2.imread('Test.jpg')
    cv2.imshow('image',img)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

It wont display the entire image in the output but a part of it .

How do i make the imshow function display the entire image in its output window ?

I am using open cv2 and python 2.7

You need to implicitly create the window with the WINDOW_NORMAL flag

cv2.namedWindow('image',WINDOW_NORMAL)

you ca then resize it using e.g.

cv2.resizeWindow('image', 600,600)

(this should give a 10x demagnification of your image).

no problem.

I don't use the python interface, so I tried to extrapolate from what I use in C++.

Great answer! Thanks!

Maybe it's necessary for someone to know: In Python the new window size must be handled as tuple of integer width and integer height. cv2.resizeWindow(window_name, (new_width, new_height))
