DK11 for Delphi | GisLayerVector.TGIS_Shape.Combine | Overloads | Constructors | Fields | Methods | Properties
Compute a new shape from self and shape provided, based on a given operation.
Syntax
// Delphi public function Combine( const _shape : TGIS_Shape; const _operation : TGIS_TopologyCombineType; const _returnnewobj : Boolean ) : TGIS_Shape; overload;
// C++ Builder public: TGIS_Shape* Combine( TGIS_Shape* const _shape, TGIS_TopologyCombineType* const _operation, const bool _returnnewobj ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _shape | TGIS_Shape | shape to combine with |
| _operation | TGIS_TopologyCombineType | operation code; what kind of operation should be perform between (current shape) and (_shape) |
| _returnnewobj | Boolean | if True, then result will be returned in a newly created object; if False, then self object will be returned |
Result
| Type | Description |
|---|---|
| TGIS_Shape | If _returnnewobj=True, then returns newly created shape. Otherwise returns modified or unmodified self object. |
Remarks
Internally it uses Combine method of TGIS_Topology class.
