Compass

The Compass Bean is represented by the IlvJCompass class. This Bean displays a compass indicating the geographic or cartographic north of the map.

To include the Compass Bean in your application, write the following lines of code:

IlvJCompass compass = new IlvJCompass();
compass.setView(view);

The Compass Bean then listens to view transformation changes, and check the rotation value to display north direction.

You can customize many parts displayed on the compass such as:

compass.setCartographicNeedleStyle(IlvCompass.NEEDLE_STYLE_CROSS);

compass.setCartographicBackground(Color.blue);

compass.setCartographicForeground(Color.gray);
