You will need to create a PNG image with transparent pixels, so only the center parts are non-transparent. That way you can create any shape you'd like.

Hi Yan,

PictureMarkerSymbol has the height and width and doesn't have any Style propery like SimpleMarkerSymbol.
In that case I believe you may create a CompositeSymbol using both SimpleMarkerSymbol with Style "Circle" and PIctureMarkerSymbol as below:

/////////

var symbol = new CompositeSymbol();
 symbol.Symbols.Add(new SimpleMarkerSymbol() { Style = SimpleMarkerSymbolStyle.Circle, Color = Colors.Blue, Size = 100 });

var symbolUri = new Uri(
 "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Recreation/FeatureServer/0/images/e82f744ebb069bb35b234b3fea46deae");

PictureMarkerSymbol campsiteSymbol = new PictureMarkerSymbol(symbolUri);

campsiteSymbol.Height = 40;
 campsiteSymbol.Width = 40;

symbol.Symbols.Add(campsiteSymbol);

// Create location for the campsite
 MapPoint campsitePoint = new MapPoint(-223560, 6552021, SpatialReferences.WebMercator);

// Create graphic with the location and symbol
 // Graphic campsiteGraphic = new Graphic(campsitePoint, campsiteSymbol);

Graphic campsiteGraphic = new Graphic(campsitePoint, symbol);

////////

I have used "RendererPictureMarkers" sample to test. Hope that helps.
