Add a point to the last part of the shape.
// Delphi public procedure AddPoint( const _ptg : TGIS_Point ); virtual; abstract;
// C++ Builder public: virtual void AddPoint( TGIS_Point* const _ptg ) = 0;
|_ptg||TGIS_Point||point to be added|
Internal representation of a shape is the same as in the SHP file. If you want to set a new geometry, this will call Reset, AddPart, AddPoint...AddPoint. For TGIS_ShapePoint, only one Part and one Point is allowed.
See TGIS_Shape.Lock for details and example.
Adds a new 2D (X,Y) point value, specified as TGIS_Point record value, to a specific part of the shape. The new point is added at the end of specified part of the shape
