How paint.net accomplish it: show pixel coordinates when mouse is moving

Question

There is a picture in my winform, I want to show pixel coordinates when mouse is moving, and whether zoom in or out, the same pixel's coordinates don't change, just like what paint.net does. Appreciate for any idea.

Answer 1

about the mouse coordinate, you should use Matrix to track back mouse coordinate.

see: Back track the mouse

Answer 2

You need to handle the MouseMove event and get the location from e.X and e.Y.

You can divide the location by your zoom factor.
