Opacity of Dynamic Map

[VIKRANTKRISHNA]

I have a dynamic map with annotation, point, line and polygon layer. One of the polygon layer is set to be 60% transparent ion Map Document. When I load the dynamic map without setting opacity property, the polygon layer does not show its default transparency. And, if I set the opacity for dynamic map , all the layers shows as transparent.

Is there a way to just show layers as its in Map Document?

You may need to add that map as two separate dynamic layers, and specify the relevant visibleLayers for each dynamic layer.

- create a dynamic layer for the polygon (eg, visibleLayers = [2]) and set its opacity to 0.6
- create a dynamic layer for the points, lines and annotations (eg, visibleLayers = [0,1,3])

Then how does arcgis.com does it, when you open a dynamic map service in arcgis.com. It shows a layerlist on the left. That means it loads each layer as a synamic layer spaerately?

I think ArcGIS.com creates a single dynamicLayer, which contains multiple layerIds. Each layerId is shown as an item in the layer list.

What happens if you add your layer to ArcGIS.com - does the polygon correctly show with 60% transparency?

Yes, if I add dynamic map to arcgis.com, it shows polygon layer with correct transparency. I guess its loading each layer as separate dynamic map layer.
