The MagnifyGlass is used to "zoom in" a portion of an image displayed in the ImageViewer or RasterImageViewer controls when the controls InteractiveMode is set to InteractiveMode.MagnifyGlass.

When the user clicks inside the control associated with the MagnifyGlass object, the portion of the image around the mouse cursor will be zoomed in. While still clicking down, if the user moves the mouse cursor, inside the control, the zoomed in portion will change according to the mouse position showing the current portion under the cursor.
