Add a point to the last part of the shape.
// Delphi public function AddPointBearing( const _bearing : Double; const _distance : Double; const _compass : Boolean ) : Boolean; overload; virtual;
// C++ Builder public: virtual bool AddPointBearing( const double _bearing, const double _distance, const bool _compass ) /* overload */;
Name | Type | Description |
---|---|---|
_bearing | Double | bearing in radians |
_distance | Double | distance in map units |
_compass | Boolean | if True, then bearing is North oriented |
Type | Description |
---|---|
Boolean | True, then function succeed. |
If the _compass is True then the bearing will be calculated based on North. Otherwise the bearing is calculated as an angle between last vertex and new point. Shape must have at least one vertex (2 points) in a current part for non-compass computations and at least one point for compass computations. If point can not be added (because no vertex exist or an angle can not be calculated) then function return False.
