  procedure MergeLayer(
    _layer : ITGIS_LayerVector;
    _extent : ITGIS_Extent;
    _type : TGIS_ShapeType;

    _truncated : WordBool;
    _restrict : WordBool


Name Type Description
_layer ITGIS_LayerVector layer to be merged
_extent ITGIS_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 WideString SQL query for which shape will be imported
_truncated WordBool if True, then all shapes will be truncated in _extent; if False, only the shape visible in _extent will be imported ;
_restrict WordBool if True, any field structure modification will raise error, otherwise allow to resize fields


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