RemarksFor best results you should use an icon that is rotatable about its center (that is, the hotspot of the icon is at (width/2, height/2).
Heading values are automatically kept within 360 degrees, but ensuring that the heading results in a visually appropriate rotation is your responsibility.
ExamplesC#
// load our icon for the pushpin int cacheIndex = ImageUtils.IconCache.LoadIcon("C:\path_to_icon\bus.png"); // location for the pushpin LatLon ll = new LatLon(34.0, -118.0); // heading for the pushpin - we could also get this from a GPS unit, // see Navigation.Navigator.Heading ... float head = 72; // rotated 72 degrees clockwise // create the DirectionalPushPin DirectionalPushPin dpp = new DirectionalPushPin(ll, head, cacheIndex); ... // add to the RendererList so it gets drawn on the map myRendererList.Add(dpp);
