Source-Instanzmethoden.
- Map:
-
-
Füge der Karte ein Source-Objekt hinzu:
map.addSource('id', {attributes} );
-
Entnehme der Karte ein bestimmtes Source-Objekt:
map.getSource('id').sourceMemberMethod(…);
-
Entferne ein bestimmtes Source-Objekt:
map.removeSource('id');
-
- GeoJSON-Source:
-
-
Ändere den Inhalt des Source-Objektes:
geojsonsource.setData( 'geojson_url' | {geojson_object} );
-
Bestimme den Zoom, bei dem ein Cluster aufgelöst wird:
geojsonsource.getClusterExpansionZoom( 'cluster_id', callback );
Das Callback wird aufgerufen als:
callback( error, zoom )
-
Bestimme die Elemente eines Clusters auf der nächsten Zoomstufe:
geojsonsource.getClusterChildren( 'cluster_id', callback );
Das Callback wird aufgerufen als:
callback( error, [feature, …] )
-
Bestimme alle Punkte, die zu einem Cluster gehören:
geojsonsource.getClusterLeaves( 'cluster_id', limit, offset, callback );
Das Callback wird aufgerufen als:
callback( error, [feature, …] )
-
- Video-Source:
-
-
Bestimme das HTML-<video>-Element:
videosource.getVideo() → <video>;
-
Start/Stopp:
videosource.play();
videosource.stop();
-
Aktualisiere die Position:
videosource.setCoordinates([ [lng1,lat1], [lng2,lat2], [lng3,lat3], [lng4,lat4] ]);
-
- Image-Source:
-
-
Aktualisiere die Position:
imagesource.setCoordinates([ [lng1,lat1], [lng2,lat2], [lng3,lat3], [lng4,lat4] ]);
-
Aktualisiere das Bild:
imagesource.updateImage({'url':'image_url', 'coordinates':[ pt1, pt2, pt2, pt3 ]});
