Smooth shape routine
Syntax
// Delphi public function Smooth( const _factor : Integer; const _returnnewobj : Boolean ) : TGIS_Shape; overload;
// C++ Builder public: TGIS_Shape* Smooth( const int _factor, const bool _returnnewobj ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _factor | Integer | smooth factor, number of points iterations - number of output points = number of input point * _factor |
| _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. |
