Zak,
I was able to get the google imagery to display with success thanks to your
help. It seems like my map projections weren't getting along with googles.
Now my next question is kinda a curve ball. In my past implementations I
have been using Weblayouts(not fusion) to display my maps to individuals
customers. The process of creating the maps were dynamic so different user
have different dataset and different layers. I was able to accomplish this
by using the Maestro API and manipulating my weblayout,map,and add layers at
runtime. My question is there any clean way to accomplish(besides modifying
the xml) this by modifying the application definition dynamically in the
Maestro API. In the past I was able to accomplish this using weblayouts by:
Uri host = new
Uri(ConfigurationSettings.AppSettings["MgFCGI_Path"].ToString());
HttpServerConnection conn = new HttpServerConnection(host,
SessionID, "en", true);
WebLayout webLayout =
conn.GetWebLayout(LayoutResourceID.ToString());
MapDefinition mapdef =
conn.GetMapDefinition(MapResourceID.ToString());
//add layers to map
foreach (MapLayerType layer in LayersToAdd)
{
layer.Visible = true;
layer.ExpandInLegend = true;
mapdef.Layers.Add(layer);
//mapdef.BackGroundColorAsHTML = "dbeaff";
}
//add our layer group collection to map definition
//create base map definition
MapDefinitionTypeBaseMapDefinition baseDef = new
MapDefinitionTypeBaseMapDefinition();
baseDef.BaseMapLayerGroup = BaseGroupCollection;
mapdef.BaseMapDefinition = baseDef;
baseDef.FiniteDisplayScale = new DoubleCollection();
baseDef.FiniteDisplayScale.Add(0);
baseDef.FiniteDisplayScale.Add(10000);
baseDef.FiniteDisplayScale.Add(100000);
baseDef.FiniteDisplayScale.Add(250000);
baseDef.FiniteDisplayScale.Add(600000);
baseDef.FiniteDisplayScale.Add(1000000);
baseDef.FiniteDisplayScale.Add(1500000);
baseDef.FiniteDisplayScale.Add(2000000);
baseDef.FiniteDisplayScale.Add(2500000);
baseDef.FiniteDisplayScale.Add(3000000);
baseDef.FiniteDisplayScale.Add(4000000);
baseDef.FiniteDisplayScale.Add(6000000);
baseDef.FiniteDisplayScale.Add(10000000);
//Save the modified map at its new temporary location
conn.SaveResource(mapdef);// , tempMapDef);
//Generate a temporary WebLayout id
string tempWebLayout = new ResourceIdentifier("MyLayout",
ResourceTypes.WebLayout, conn.SessionID);
//Update the WebLayout to point at the modified MapDefinition
webLayout.Map.ResourceId = mapdef.ResourceId;
//Save the modified layout at its new temporary location
conn.SaveResource(webLayout);
WebLayoutString = webLayout.ResourceId.ToString();
---------------------------------------------------------------------------------
--------------------------------------------------------------------------------
currently I am trying the following for application definiton
//get the application definition
ApplicationDefinitionType app_Type =
conn.GetApplicationDefinition(FlexibleLayoutResourceID.ToString());
//iterate through the map groups find the reourceid of the map and set it to
the modified with layers
MapGroupTypeCollection map_Coll = app_Type.MapSet;
foreach (MapGroupType mg_Type in map_Coll)
{
MapTypeCollection mcollection = mg_Type.Map;
foreach
(OSGeo.MapGuide.MaestroAPI.ApplicationDefinition.MapType m_type in
mcollection)
{
CustomContentType c_Type = m_type.Extension;
System.Xml.XmlElement[] elements = c_Type.Any;
//here is where i would set the new map resource id
to pointot the generated map with layers
}
}
//Save the modified map at its new temporary location
conn.SaveResource(mapdef);
//Generate a temporary application definition id
string tempWebLayout = new ResourceIdentifier("MyApplication",
ResourceTypes.ApplicationDefinition, conn.SessionID);
//Save the modified layout at its new temporary location
conn.SaveResourceAs(app_Type,app_Type.ResourceId.ToString());
Thanks,
JPS
