InheritanceArcIMSMapServiceLayer Inheritance DynamicMapServiceLayer Inheritance Layer Inheritance mx.core.UIComponent

Allows you to add ArcIMS image services to your map.
    Requirements:
  1. crossdomain.xml file on the ArcIMS server.
  2. ArcIMS service need to contain FEATURECOORDSYS and FILTERCOORDSYS with id's or string's.

Note that ArcIMSMapServiceLayer, like all layers, extend UIComponent and thus include basic mouse events, for example, click, mouseOut, mouseOver, and mouseDown, as well as other events like show and hide, and general properties, such as alpha and visible.

Example: MXML usage of ArcIMSMapServiceLayer: 
 <esri:ArcIMSMapServiceLayer
     serviceHost="http://www.geographynetwork.com"
     serviceName="ESRI_Snow"/>
Example: MXML to set specific visible layers: 
 <esri:Map>
     <esri:ArcIMSMapServiceLayer serviceHost="http://www.geographynetwork.com" serviceName="Census_TIGER2000">
         <esri:visibleLayers>
             <s:ArrayCollection>
                 <fx:String>U.S. States</fx:String>
                 <fx:String>Non-U.S. Land</fx:String>
                 <fx:String>Oceans and Seas</fx:String>
             </s:ArrayCollection>
         </esri:visibleLayers>
     </esri:ArcIMSMapServiceLayer>
 </esri:Map>
