Create a raster from subset of bands

Question

Hello all

I have a multi band raster (9 bands) and I need to create a 3 band raster from bands 1,3,4 in ArcObjects.

The way I do it in ArcMap is the MakeRasterLayer with the 3 needed bands and then copy raster it to a new name.

I cannot do the MakeRasterLayer in ArcObjects and retrieve the results.

The commands works successfully but I cannot get the results.

Here is my code:

ESRI.ArcGIS.DataManagementTools.MakeRasterLayer MakeRasterTool = new ESRI.ArcGIS.DataManagementTools.MakeRasterLayer();
 MakeRasterTool.in_raster = @D:\Rasters1\MultiBand.TIF;
 MakeRasterTool.out_rasterlayer = "Three";
 MakeRasterTool.band_index = "1,3,4";
 result = GP.Execute(MakeRasterTool, null) as ESRI.ArcGIS.Geoprocessing.IGeoProcessorResult;

ESRI.ArcGIS.Geoprocessing.IGPUtilities gpUtils = new ESRI.ArcGIS.Geoprocessing.GPUtilities();
 IRaster RD = gpUtils.DecodeRaster(result.GetOutput(0));

I tried DecodeRasterLayer too with the same results.

Should I opened somehow the raster "Three"?

Thanks

The following VBA worked for me: Public Sub Test() Dim pGP As IGeoProcessor2 Set pGP = New GeoProcessor pGP.OverwriteOutput = True pGP.AddOutputsToMap = False Dim pVA As IVariantArray Set pVA = New VarArray With pVA .Add "Multispectral_L5151038_03820110324_MTL" ' Layer in map but could be full path .Add "myRaster" .Add "#" .Add "#" .Add "1;2;3" ' Note semicolon separated End With Dim pGR As IGeoProcessorResult2 Set pGR = pGP.Execute("MakeRasterLayer_management", pVA, Nothing) If pGR.Status = esriJobSucceeded Then With pVA .RemoveAll .Add "myRaster" .Add "C:\scratch\aaa.tif" End With pGP.AddOutputsToMap = True Set pGR = pGP.Execute("CopyRaster_management", pVA, Nothing) End If End Sub‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
