Zoom-In-Out-with-OpenCV

I believe a lot of people is concerned about this issue. So, I implemented a C++ class, containing OpneCV Window. This project can zoom in / out image showed on OpenCV window without other UI frameworks, like MFC, C#, Java Swing and etc.

Visual Effect:

Usage:

1.Download Visual Studio and Install

2.Set up your OpenCV include directory, library directory, name of .lib

3.Place OpenCV.dll to the output directory of this project (for me, it's Zoom-In-Out-with-OpenCV\Debug)

4.Run and Experience

or you can just copy OpenCVWindowEx.h, OpenCVWindowEx.cpp to your own project

Class Usage:

COpenCVWindowExt window ("Src"); // Create an OpenCVWindowEx with name (same as original API)
window.ImRead ("test2.bmp");     // Read an Image with this window and show it
waitKey (0);                     // Wair for user's operation
