Interface ScreenCoordinateListener

public interface ScreenCoordinateListener
ScreenCoordinateListener This interface defines functions that convert mouse coordinates to image file coordinates. ViewJComponentEditImage is an example of a ScreenCoordinateListener. Given input mouse position from a MouseEvent: MouseEvent.getX(), MouseEvent.getY(), and the current image slice (in local coordinates or 0 for 2D images) the ScreenCoordinateListener converts the mouse position to image file coordinates. The ScreenCoordinateListener is responsible for canvas zoom, image file resolutions, and image orientation information that is used to convert the input points. All that information is hidden from the calling function.
