Example 1 with LImageOverlay

use of org.vaadin.addon.leaflet.LImageOverlay in project v-leaflet by mstahv.

the class PlainImage method getTestComponent.

@Override
public Component getTestComponent() {
    leafletMap.setCrs(Crs.Simple);
    ExternalResource url = new ExternalResource("https://www.dropbox.com/s/oajfgu8onqxfo0g/photo.jpg?dl=1");
    // The size of this image is 3264 * 2448, scale it here to suite better
    // for default zoomlevels
    final Bounds bounds = new Bounds(new Point(0, 0), new Point(244.8, 326.4));
    LImageOverlay imageOverlay = new LImageOverlay(url, bounds);
    leafletMap.addLayer(imageOverlay);
    // You can fit it directly or to another extend like here, you could also
    // use multiple images on the background
    leafletMap.setMaxBounds(new Bounds(new Point(0, 0), new Point(300, 500)));
    // draw line from corner to corner
    leafletMap.addLayer(new LPolyline(new Point(0, 0), new Point(244.8, 326.4)));
