I need apply the zoom in and zoom out in the imagem of the my form with OpenCV. But, my great problem is that I don't know whats the function I use in the Visual Studio C++. In the examples of the internet the zoom in and zoom out are applied with Visual C# or Visual Basic.

You can use resize function

Doc :

If you want to decimate the image by factor of 2 in each direction, you can call the function this way: // specify fx and fy and let the function compute the destination image size.

resize(src, dst, Size(), 0.5, 0.5, interpolation);
