How to add symbol image to arcScene using local .png or .img file?

I used this code but it doesnt work:

GraphicsOverlay graphicsOverlay = new GraphicsOverlay();
sceneView.getGraphicsOverlays().add(graphicsOverlay);

// An image file on the hard drive.
File file = new File("C:\\Users\\user\\Documents\\IMG1.jpg");

String localUri = file.toURI().toString();

PictureMarkerSymbol markerSymbol = new PictureMarkerSymbol(localUri);
markerSymbol.setHeight(100);
markerSymbol.setWidth(100);

markerSymbol.loadAsync();
com.esri.arcgisruntime.geometry.Point symbolPoint = new com.esri.arcgisruntime.geometry.Point(20, 20, SpatialReferences.getWgs84());
Graphic symbolGraphic = new Graphic(symbolPoint, markerSymbol);
markerSymbol.addDoneLoadingListener(() -> graphicsOverlay.getGraphics().add(symbolGraphic));

If you are working with a file on the local OS, you don't need a full URI format, you can just use the file on its own.

I just tried this out with the following code:

GraphicsOverlay graphicsOverlay = new GraphicsOverlay(); mapView.getGraphicsOverlays().add(graphicsOverlay); // An image file on the hard drive. PictureMarkerSymbol markerSymbol = new PictureMarkerSymbol("./FireStation.png"); markerSymbol.setHeight(100); markerSymbol.setWidth(100); markerSymbol.loadAsync(); markerSymbol.addDoneLoadingListener(() -> { System.out.println("loaded status " + markerSymbol.getLoadStatus()); if (markerSymbol.getLoadStatus() == LoadStatus.LOADED) { // use the symbol Point point = new Point(0,0); Graphic graphic = new Graphic(point,markerSymbol); graphicsOverlay.getGraphics().add(graphic); } else { // error state as it didn't load System.out.println("Failed to load: " + markerSymbol.getLoadError().getCause()); } });

Does this work for you?

An alternative solution would be to construct the symbol directly from a JavaFX image. If you are already using the image elsewhere in your app for example, you could do this:

Image image = new Image("file:FireStation.png", 100, 100, false, false); PictureMarkerSymbol markerSymbol = new PictureMarkerSymbol(image);
