|
|
| mGlobalRect |
Bounding rect of layer in global coordinates
|
|
| mGroupName |
Group name that the layer is in. NULL for no group. Separated with <sep> if multiple levels.
|
|
| mHasRasterData |
Does this layer have raster or elevation data?
|
|
| mHasVectorData |
Does this layer have vector data (the features counts can all be 0 for things like map catalogs)
