Using the values of 'valueRaster', determines which raster in 'collectionofRasters' will be used for the output values.
[Visual Basic .NET] Public Function Pick ( _ ByVal valueRaster As IGeoDataset, _ ByVal collectionOfRasters As IGeoDataset _ ) As IGeoDataset
[C#] public IGeoDataset Pick ( IGeoDataset valueRaster, IGeoDataset collectionOfRasters );
[C++]
HRESULT Pick(
IGeoDataset* valueRaster,
IGeoDataset* collectionOfRasters,
IGeoDataset** Pick
);
[C++]Parameters
valueRaster [in]valueRaster is a parameter of type IGeoDataset
collectionOfRasters [in]collectionOfRasters is a parameter of type IGeoDataset
Pick [out, retval]Pick is a parameter of type IGeoDataset
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Spatial Analyst Extension.
Remarks
| valueRaster | an input Raster, RasterDataset, RasterBand, or RasterDescriptor defining the expression position that will be executed |
| collectionOfRasters | name of a multiband Raster
If the value in the input valueRaster equals '1', then the first Raster in the collectionOfRasters will be used to compute the value for the output Raster. If the value in the input valueRaster equals '2', then the second Raster in the collectionOfRasters will be used to compute the value for the output Raster; if the value on the input valueRaster equals 'n', the expression in the 'nth' position in the collectionOrRasters will be used. |
- The method returns a reference to a Raster object.
