Builds an image layer.

Available also on: .NET | Java | ActiveX.

Syntax

// Delphi
public
  procedure Build(
    const _path : String;
    const _cs : TGIS_CSCoordinateSystem;
    const _ext : TGIS_Extent;
    const _pixelsize : Double
  ); overload; virtual;
// C++ Builder
public:
  virtual void Build(
    const UnicodeString _path,
    TGIS_CSCoordinateSystem* const _cs,
    TGIS_Extent* const _ext,
    const double _pixelsize
  ) /* overload */;

Parameters

Name Type Description
_path String path to a layer; if empty then layer in-memory
_cs TGIS_CSCoordinateSystem Coordinate system of the layer
_ext TGIS_Extent extent of the layer expresses in Coordinate System units (_cs)
_pixelsize Double pixel layer resolution in Coordinate System units

Remarks

Layer's extent might be little expanded to ensure exact _pixelsize. To create a grid layer see method overloads.
