[mapguide-users] Resample or Clip expression for WMS connection

[Sowinski, Keith - DOT]

Ugh…Now I’m getting a “not implemented” exception on that method.  Starting to wonder if this is even possible from Map 3D.

That's strange. Then again perhaps Map3D's implementation of this API behaves differently from its MapGuide counterpart.

Either way, what you want is the name of the raster property definition in the feature class. From your current MgLayerBase (lyr) you can get its class definition (lyr.GetClassDefinition()).

In that class definition, loop through its property collection until you find one whose type is raster. The name of that property is what you want to pass into CLIP()

Thank you Jackie! This is very helpful.

Now I’m getting and Exception when executing the ISelect.  I think it is because lyr.GetFeatureGeometryName() returns an empty string.
