I am looking for solutions to the following task and I am hoping someone can assist. I am using Visual C++ on windows XP. My task is
to display a rectangular box on an image. This box can be grabbed with the pointer and moved over all parts of the image. As the box moves, whatever part of the image it is over is grabbed and displayed in a larger frame next to the smaller one. It should also be able to zoom in/out. Any suggestions would be greatly appreciated.
