Example 21 with Coord

use of com.codename1.maps.Coord in project codenameone-google-maps by codenameone.

the class MapContainer method getBoundingBox.

Example 22 with Coord

use of com.codename1.maps.Coord in project codenameone-google-maps by codenameone.

the class MapContainer method getScreenCoordinates.
