I understand how to set my WMS, KML layers to turn on by default in the API and how to adjust opacity etc., but how to I control the Geoportal default layers?

In the below linked example I want to have Cadastral on by default (as start upand have 100% opacity)...

http://www.wm.edu/as/cga/Online%20GI...Maps/index.php

I know the commands

visibility: true
Opacity: 1

but I do not understand where to put these lines of code to work on the Cadastral Layer (or any of the Geoportal layers such as Buildings, Cadastral, Hydrography)


To summarize.
I can alter Visibilty and Opacity on my WMS layers and I can alter them as a user on the client but how in my code below would I set Cadastral to be on by default as startup (checked) and have 100% Opacity.

Many Thanks

Stu

Comme cela, je crois:

minZoomLevel: 1,

isBaseLayer: false,

});
viewer.addGeoportalLayer('CADASTRALPARCELS.PARCELS',{visibility: true,
opacity:1.0,
				minZoomLevel:16,
				maxZoomLevel:20});
....
