[mapguide-users] Map Image Transformation

[Andy Morsell]

I think you may have to do this with two different map definitions, one with
UTM assigned and the other with LL84 assigned.  Get the current view extents
(MgMap::GetMapExtent) from your UTM map.  This will be an MgEnvelope.  Then
apply a coordinate transformation (MgCoordinateSystemTransform) to the
envelope and use that as the basis for rendering your LL84 map
(MgRenderingService::RenderMap).

I want to be able to Produce Map Images in Different Coordinate Systems...
..i.e. I have a mapdefinition Authored in NAD83 UTM-16 Meter...I want to
Render the current View Extents into a LL84 Image of the Map.....

....I can get the MapObjects SRS...but there is no SetSRS on the
MapObject...So How Do I change ths SRS of the MapObject, or Rendering
Service So it Renders in a different Coordinate System?
