TGIS_Shape.AddPointBearing(Double; Double) method

DK11 for Delphi | GisLayerVector.TGIS_Shape.AddPointBearing | Overloads | Constructors | Fields | Methods | Properties

Add a point to the last part of the shape.

Available also on: .NET | Java | ActiveX.

Syntax

// Delphi
public
  function AddPointBearing(
    const _bearing : Double;
    const _distance : Double
  ) : Boolean; overload; virtual;
// C++ Builder
public:
  virtual bool AddPointBearing(
    const double _bearing,
    const double _distance
  ) /* overload */;

Parameters

Name Type Description
_bearing Double bearing in radians
_distance Double distance in map units

Result

Type Description
Boolean True, then function succeed.

Remarks

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.
