Many of our functions/classes take coordinates in image coordinates or bitmap coordinates.  The values need to be from 0, 0 to Image.Width, Image.Height. 
However, in mouse events (mouse up, mouse down, mouse move, etc) the coordinates given as parameter are in client coordinates.  They will range from 0,0 to ImageViewer.Width, ImageViewer.Height.

This demo shows you how to convert from the client coordinate system to the image coordinate system in the mouse move event.  The coordinates for both are displayed in the status strip.  To see the effect you will want to load a large image and either scroll it, or have the viewer fit the image to the screen.

This demo is written in C# as
