[Users] configuring layers in geoexplorer

[Lemarchand, Johan]

Hi,

Thanks for your reply but I don't see where I can change the image
format and set the transparency. The layers are displayed with a grey
background and are not transparent. How can I specify the output image
format for my layers?

 Ext.BLANK_IMAGE_URL = "theme/img/blank.gif";
            var app = new GeoExplorer.Embed({
                //proxy: "/proxy/?url=",
                about: {
                    title: 'Example Map',
                    "abstract": 'A description of the map\'s contents',
                    keywords: "example, test, development",
                    contact: "Georj the Robot, Outreach Tribe Leader,
OpenGeo, http://opengeo.org/"
                },
                ows: {
                    "demo": "http://extranet.who.int/geoserver/ows"
                },
                map: {
                    layers: [{
                        name: "WHO:GIM_MONITORING_GEOMETRY_MEASURES",
                        ows: "demo"
                    },{
                        name: "World_countries_legal",
                        ows: "demo",
                        background: true,
                        visibility:true
                    }],
                    center: [0, 0],
                    zoom: 4
                }
            });

Thanks in advance and I will be interested to know when the new tag 0.2
will be ready.

regards,
Johan

I should add that the latest "release" of the app is actually what you 
get in the zip archive linked from this blog post: 
http://blog.opengeo.org/2009/06/17/geoexplorer-preview/

This comes from the 0.1.x branch - not the trunk.

If you are trying out the app at the trunk, you can use more than one 
OWS.  I'll be making another tag for 0.2 in a few days.  This tag will 
come with some basic docs.
