Can't zoom out on raster layer

Dear Gurus!

I would like to implement zoom out on map which contains raster layer.
I created simple program to check this option, but can't understand how to do it.

So, here is my code:

public partial class MainWindow : Window { MapView _mapView = null; public MainWindow() { InitializeComponent(); _mapView = MyMapView; try { #region Raster string qwe4 = Path.GetFullPath(@"D:\to_check_img\12_daniel_can_bc-207.jpg"); RasterLayer myRasterLayer4 = new RasterLayer(qwe4); //myRasterLayer.MinScale = 450000; //myRasterLayer.MaxScale = 1000000; LoadRaster(myRasterLayer4); Map map = new Map(); map.OperationalLayers.Add(myRasterLayer4); MyMapView.Map = map; #endregion } catch (Exception ex) { } } private async void LoadRaster(RasterLayer myRasterLayer) { await myRasterLayer.LoadAsync(); ///not working //await _mapView.SetViewpointScaleAsync(50000); //await _mapView.SetViewpointCenterAsync(new MapPoint(myRasterLayer.FullExtent.XMin, myRasterLayer.FullExtent.YMin), 50000); } }

After it, I see an image on map with current scale. For it I added

When I run an application I see image with current scale:

But I don't have a possibility to zoom out from this scale.

I really need to know if there is any possibility to zoom out when we have a nongeoreferenced map and image layer on it.

As you see I tried to use MinScale, MaxScale, SetViewpointScaleAsync, but it didn't work.

Thanks in advance!
