TGIS_Topology.Union(TGIS_Shape; TGIS_Shape; Boolean) method
DK11 for Delphi | GisTopology.TGIS_Topology.Union | Overloads | Constructors | Methods | Properties | Events
Compute a new shape as an union of two shapes provided.
Syntax
// Delphi public function Union( const _shpA : TGIS_Shape; const _shpB : TGIS_Shape; const _fixshape : Boolean ) : TGIS_Shape; overload;
// C++ Builder public: TGIS_Shape* Union( TGIS_Shape* const _shpA, TGIS_Shape* const _shpB, const bool _fixshape ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _shpA | TGIS_Shape | first shape |
| _shpB | TGIS_Shape | second shape |
| _fixshape | Boolean | if True, then checks and eventually fixes the input shapes for common topological problems, like self-crossings, overlapped parts etc. |
Result
| Type | Description |
|---|---|
| TGIS_Shape | returns new shape as union of two others |
Remarks
See TGIS_Shape.Combine for example.
