RE: [mapguide-users] Manipulating Maps in a Session, .NET API
Tiling service should provide function that returns array of tile positions (row/column), given MgGeometry (or MgEnvelope) to query tile index, map and scale. It's currently implemented on client (AJAX) side only. I'm thinking of filing an enhancement ticket for this.

RE: [mapguide-users] Manipulating Maps in a Session, .NET API
Hi Nothi, Please see Maestro API: http://trac.osgeo.org/mapguide/wiki/maestro You need to reference OSGeo.MapGuide.MaestroAPI.dll and MapGuideDotNetApi.dll libraries to get started. Then look for RuntimeClasses.RuntimeMap, I'll see to post some coding examples on Wiki page. It's still thin on documentation but if you have some previous experience with managed MG API then it's rather straightforward. Kenneth also did a great job of enabling (de)serialization fro an to managed types.

Re: [mapguide-users] Manipulating Maps in a Session, .NET API
There is no scale in the runtime map (MgMap). When you request that the image is rendered, you supply dpi, resolution and either center/scale or extent. You cannot store the scale or the center in the runtime map, you must store it locally in your client. Regards, Kenneth Skovhede, GEOGRAF A/S Johann Nothbauer skrev: Hi All!
