Under Mac OSX Yosemite 10.10.1, the image I want to display is too large and too long for the window. I would like it to adjust to the window.

Here is my code :

import cv2 import sys

image = cv2.imread(fname)

if image is None: print 'Failed to load image file:', fname sys.exit(1)

cv2.namedWindow("Trial")

cv2.imshow("Trial",image)

I'm a beginner in opencv, so please, be patient.

no, it's not related to your os. (well, apple users always think it is so...)

cv2.namedWindow("Trial") # here's the problem

if you open a namedWindow with default args, it will use cv2.WINDOW_AUTOSIZE , meaning: the window will get adjusted to the image size

what you want instead is:

 cv2.namedWindow("Trial", cv2.WINDOW_NORMAL)

this will do the opposite, resizing the image to your windowsize (you can also resize it now manually(or from code))

My previous post was not accurate enough.

I have already tested :

cv2.namedWindow("Trial", cv2.WINDOW_NORMAL)

And it doesn't work either.

I do not want to resize my image form the code, because I have a lot of images to process, and their size can vary.
