DK11 for Delphi | GisInterfaces.IGIS_Viewer.Locate | Overloads | Methods | Properties
Locate a shape that is near _pt, but is closer than _prec distance.
// Delphi public function Locate( const _pt : TPoint; const _prec : Integer ) : TGIS_ShapeAbstract; overload;
// C++ Builder public: TGIS_ShapeAbstract* Locate( TPoint* const _pt, const int _prec ) = 0 /* overload */;
Name | Type | Description |
---|---|---|
_pt | TPoint | reference point /searching point/ in pixels |
_prec | Integer | precision /not a longer distance than/; for points inside the polygon (if _prec >= 0) the distance will be multiply by 0.95 (to prefer points inside the polygon) but will not be bigger then _prec; for point distance will be multiplied by 0.9 to prefer points over lines and polygons; precision is express in pixels |
