Most likely you installed OpenCV without QT. Which OpenCV version are you using?

BahaaMansour commented 5 years ago

latest version what is QT?

Cartucho commented 5 years ago

So you are using version 4.0.1. Which OS are you using? How did you install it... with pip install?

Any fix to Zooming in and zooming out? I'm using python 3.6, opencv-contrib-3.4 on windows.

Hello! So to summarize OpenCV is planning on dropping the QT requirement and implement their own Zoom In and Zoom Out (they announced it as a GSoC project).

If you wanted to use QT on Windows you would have to manually install OpenCV, instead of using pip install, but, that would be an arduous task.

I am planning on dropping the OpenCV interface and move it to tkinter and implement the zoom by myself.

Hello guys, I have good news OpenCV is now removing the QT dependency in Google Summer of Code 2019. This issue will be fixed by this summer.

I installed OpenCV. Zoom does not work.

Hi , The tool is great ! But the zoom in/out problem is critical in large images annotation task. Is this issue will be fixed soon ?

Thank You
