DK11 for Delphi | GisLayer.TGIS_Layer.RecalcProjectedExtent | Constructors | Fields | Methods | Properties | Events

Recalculates a projected extent.

Available also on: .NET | Java | ActiveX.

Syntax

// Delphi
public
  procedure RecalcProjectedExtent; virtual;
// C++ Builder
public:
  virtual void RecalcProjectedExtent(void);

Remarks

Calculation is only an estimation based on a 72x36 grid. The grid is necessary because any point from an extent can be moved the after projection to, in fact, any new location. This grid size is used because it will be no more than 5x5 degrees.
