TGIS_LayerPixel.Build(Boolean; TGIS_CSCoordinateSystem; TGIS_Extent; Double) method
DK11 for Delphi | GisLayerPixel.TGIS_LayerPixel.Build | Overloads | Constructors | Fields | Methods | Properties | Events
Builds an in-memory layer.
Syntax
// Delphi public procedure Build( const _grid : Boolean; const _cs : TGIS_CSCoordinateSystem; const _ext : TGIS_Extent; const _pixelsize : Double ); overload; virtual;
// C++ Builder public: virtual void Build( const bool _grid, TGIS_CSCoordinateSystem* const _cs, TGIS_Extent* const _ext, const double _pixelsize ) /* overload */;
Parameters
| Name | Type | Description |
|---|---|---|
| _grid | Boolean | if true then layer will be treated as grid a image layer will be created otherwise |
| _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 file based layer - see method overloads.
