Name Type Description
_layer TGIS_LayerVector layer to be imported
_extent TGIS_Extent starting extent of layer - can't be zero sized
_type TGIS_ShapeType shape type supported by a layer; if gistypeUnknown is used then import will try to recognize shape on its own;
_scope string
SQL query for which shape will be imported
_shape TGIS_Shape if not nil, then only shapes matched _de9im matrix with _shape will be found
_de9im string
DE-9IM matrix of comparison
_truncated bool
if True, then all shapes will be truncated in _extent; if False, only the shape visible in _extent will be imported ;


Remember to assign 'path' property to the layer you want to import from, for proper import of the new layer to a file.
Use this method to import a layer. To do this, simply create a new layer, choose a layer to import from and use ImportLayer method with proper params. See also the opposite method, ExportLayer.
