I changed the property from ImageryLayer to rasterFunction, however that caused the imagery not to draw. Any help appreciated.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="jsapi.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/82280i3B29360A13E0C879/image-size/medium?v=v2&amp;px=400" role="button" title="jsapi.png" alt="jsapi.png" /></span></P><P> </P><P><STRONG>EDIT: </STRONG>The app I'm&nbsp; working with uses webmaps.
