Performs a conditional if/else evaluation.
[Visual Basic .NET] Public Function Con ( _ ByVal conditionalRaster As IGeoDataset, _ ByVal trueRaster As IGeoDataset, _ [ByRef falseRaster As Object] _ ) As IGeoDataset
[C#] public IGeoDataset Con ( IGeoDataset conditionalRaster, IGeoDataset trueRaster, ref object falseRaster );
[C#]
Optional Values
falseRaster To indicate that this parameter is undefined, first define a variable object Missing = Type.Missing; then pass this in as ref Missing.
[C++]
HRESULT Con(
IGeoDataset* conditionalRaster,
IGeoDataset* trueRaster,
VARIANT* falseRaster,
IGeoDataset** Con
);
[C++]Parameters
conditionalRaster [in]conditionalRaster is a parameter of type IGeoDataset
trueRaster [in]trueRaster is a parameter of type IGeoDataset
falseRaster [optional] falseRaster is a parameter of type VARIANTTo indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND.
Con [out, retval]Con is a parameter of type IGeoDataset
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Spatial Analyst Extension.
Remarks
| conditionalRaster | an input Raster, RasterDataset, RasterBand, or RasterDescriptor. The values should be comprised of “1”’s and “0”’s with a “1” representing True condition and a “0” a False condition |
| trueRaster | the value that will be used as the output value if the conditionalRaster is True |
| [falseRaster] | the value that will be used as the output value if the conditionalRaster is False. If no falseRaster is specified, all False values (“0”’s) in the conditionalRaster will be assigned NoData |
- The method returns a reference to a Raster object.
