var imageParameters = new esri.layers.ImageParameters(); imageParameters.layerIds = [0]; imageParameters.layerOption = esri.layers.ImageParameters.LAYER_OPTION_SHOW; imageParameters.transparent = true; var dLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer",{"imageParameters":imageParameters}); map.addLayer(dLayer);
If I add a layer to a map it displays the map feature (or graphic? Is that the right terminology?). Is the default symbol what is listed in the service properties?
