const IlvMapInfo targetMapInfo,
IlvMapsError &  status 
) const
virtual

Translates an IlvMapFeature into a graphic object.

Warning
This renderer handles projection conversion.
Parameters
featureThe map feature to be translated.
targetMapInfoThe target map info.
statusSet to an error code if the renderer cannot process the map feature (most of the time, because the renderer does not support the feature geometry, but it can also indicate that a projection error occurred).
Returns
An IlvGraphic object or a null pointer if a severe error occurred.

Implements IlvFeatureRenderer.
