I am new to the ArcGIS SDK and I can't seem to find how to add a picture on top of the map, using 4-coner coordinates. In the snippet below, coords has the coordiantes for 4 points. I know all I try to do in this example is to fill a polygon with a picture, so if anyone has an example on how to overlay a picture over the map, I would appreciate it. Thanks.
System.Uri myPictureUri = new System.Uri("https://upload.wikimedia.org/wikipedia/commons/0/03/Piwnice_aerial_view.jpg");
Esri.ArcGISRuntime.Symbology.PictureFillSymbol pictureFillSymbol = new Esri.ArcGISRuntime.Symbology.PictureFillSymbol();
pictureFillSymbol.SetSourceAsync(myPictureUri);
var graphicsLayer = MyMap.Layers["MyGraphicsLayer"] as Esri.ArcGISRuntime.Layers.GraphicsLayer;
if (graphicsLayer == null)
{
graphicsLayer = new Esri.ArcGISRuntime.Layers.GraphicsLayer();
graphicsLayer.ID = "MyGraphicsLayer";
MyMap.Layers.Add(graphicsLayer);
}
System.Collections.ObjectModel.ObservableCollection<Esri.ArcGISRuntime.Geometry.PointCollection> rings =
new System.Collections.ObjectModel.ObservableCollection<Esri.ArcGISRuntime.Geometry.PointCollection>();
Esri.ArcGISRuntime.Geometry.PointCollection pointCollection = new Esri.ArcGISRuntime.Geometry.PointCollection(MyMapView.SpatialReference);
for (int i = 0; i < coords.Length-2; i = i + 2)
{
Esri.ArcGISRuntime.Geometry.MapPoint point;
point = Esri.ArcGISRuntime.Geometry.ConvertCoordinate.FromDecimalDegrees(coords.ToString() + " " + coords[i + 1].ToString(), MyMapView.SpatialReference);
pointCollection.Add(point);
}
rings.Add(pointCollection);
//Set Geometry
Esri.ArcGISRuntime.Geometry.Polygon p = new Esri.ArcGISRuntime.Geometry.Polygon(rings, MyMap.SpatialReference);
var overlayGraphic = new Esri.ArcGISRuntime.Layers.Graphic();
overlayGraphic.Geometry = p;
overlayGraphic.Symbol = pictureFillSymbol;
graphicsLayer.Graphics.Add(overlayGraphic);
