Creates vector contours from a raster grid layer.
// Delphi public function Generate( const _src : TGIS_LayerPixel; const _dst : TGIS_LayerVector; const _dstfld : String; const _dstfld_interval : String ) : Boolean; overload;
// C++ Builder public: bool Generate( TGIS_LayerPixel* const _src, TGIS_LayerVector* const _dst, const UnicodeString _dstfld, const UnicodeString _dstfld_interval ) /* overload */;
Name | Type | Description |
---|---|---|
_src | TGIS_LayerPixel | source grid layer |
_dst | TGIS_LayerVector | destination vector layer, must have the same CS as the source layer |
_dstfld | String | if not empty the field of the specified name will be populated with the elevation values of the contours |
_dstfld_interval | String | if not empty the field of the specified name will be populated with the contours' intervals; only for polygonal contours |
Type | Description |
---|---|
Boolean | True if the process was completed successfully; False otherwise |
'_dstfld' and '_dstfld_interval' must already exist in '_dst' layer. '_dstfld' and '_dstfld_interval' must be different.
