Returns NoData if the evaluation of the input 'conditionalRaster' is true, or returns the value specified by the 'falseRaster' if it is false, on a cell by cell basis.
[Visual Basic .NET] Public Function SetNull ( _ ByVal conditionalRaster As IGeoDataset, _ ByVal falseRaster As IGeoDataset _ ) As IGeoDataset
[C#] public IGeoDataset SetNull ( IGeoDataset conditionalRaster, IGeoDataset falseRaster );
[C++]
HRESULT SetNull(
IGeoDataset* conditionalRaster,
IGeoDataset* falseRaster,
IGeoDataset** SetNull
);
[C++]Parameters
conditionalRaster [in]conditionalRaster is a parameter of type IGeoDataset
falseRaster [in]falseRaster is a parameter of type IGeoDataset
SetNull [out, retval]SetNull is a parameter of type IGeoDataset
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Spatial Analyst Extension.
Remarks
| conditionRaster | a conditional input Raster, RasterDataset, RasterBand, or RasterDescriptor to be tested for Boolean 'True' or 'False' |
| falseRaster | defines what the output value will be
if the evaluation of the condition is False
If no argument is specified, the output will receive NoData. Unless the desired result is a grid containing all NoData, it is advisable to specify an output for this argument. |
- The method returns a reference to a Raster object.
