Accessing a raster attribute table for an image service
The following code example shows how to access the attribute table of an image service that serves thematic imagery:
[C#]
public static IRecordSet GetRasterAttributeTable(IImageServer imageServer)
{
//Get raster attribute table.
IImageServiceInfo3 isInfo = imageServer.ServiceInfo as IImageServiceInfo3;
if (isInfo.HasRasterAttributeTable)
return ((IImageServer4)imageServer).RasterAttributeTable;
else
return null;
}
[VB.NET]
Public Shared Function GetRasterAttributeTable(ByVal imageServer As IImageServer) As IRecordSet
'Get raster attribute table.
Dim isInfo As IImageServiceInfo3 = TryCast(imageServer.ServiceInfo, IImageServiceInfo3)
If isInfo.HasRasterAttributeTable Then
Dim recordSet As IRecordSet = DirectCast(imageServer, IImageServer4).RasterAttributeTable
Return recordSet
Else
Return Nothing
End If
End Function
