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 ;
_restrict bool
if True, any field structure modification will raise error, otherwise allow to resize fields


Remember to assign 'path' property to layer you want to import from for proper import a new layer to file.
Use this method to merge layers. Before the merge SaveData will be fired.
