layerDrawingOptions and custom Symbol

PaulHastings1 — Wed, 31 Oct 2012 16:57:32 GMT

can the renderers in layerDrawingOptions make use of custom symbols? i have the following custom symbol (simplified for the time being)

package symbols {    import com.esri.ags.Map;  import com.esri.ags.geometry.Geometry;  import com.esri.ags.geometry.MapPoint;  import com.esri.ags.symbols.MarkerSymbol;  import com.esri.ags.symbols.Symbol;    import flash.display.Sprite;    public class MooringSymbol extends MarkerSymbol {      public function MooringSymbol() {    super();   }      override public function clear(sprite:Sprite):void {    sprite.graphics.clear();   }      override public function draw(sprite:Sprite,geometry:Geometry,attributes:Object,map:Map):void {    if (geometry is MapPoint) {          var radius:int=15;// POC testing, production based on attributes     sprite.x=toScreenX(map,(geometry as MapPoint).x);     sprite.y=toScreenY(map,(geometry as MapPoint).y);     sprite.graphics.beginFill(0xFF0000,0.5);     sprite.graphics.drawCircle(0,0,radius);     sprite.graphics.endFill();         }     }     } }

applied to the layerDrawingOptions for a given layer:

protected function infrastructureLayer_initializeHandler(event:FlexEvent):void {         drawingOptions=infrastructureLayer.layerDrawingOptions;     var r:SimpleRenderer=new SimpleRenderer();      var dO:LayerDrawingOptions=new LayerDrawingOptions();             r.symbol=new MooringSymbol();     dO.renderer=r;     dO.alpha=1;     dO.layerId=0;     dO.showLabels=true;     dO.scaleSymbols=false;     drawingOptions[0]=dO;     infrastructureLayer.layerDrawingOptions=drawingOptions;     infrastructureLayer.refresh();     }

but it appears the symbol is never applied as that layer shows up empty. if i switch to a standard Symbol (MarkerSybol, etc.), works fine.

is approach this possible? any suggestions.

thanks.

Custom symbols are not supported unless they implement IJSONSupport and the JSON is supported by the REST API.

See:

thanks for the reply.

can i interpret that as i shouldn't be extending Symbol but constructing the symbol as JSON to send back to the server? any chance of some examples of that?

i think my real problem is server-side vs client-side symbolization.
