How to erase a portion of a geodatabase raster dataset

Summary
This article shows how to erase a portion of a raster dataset stored in a file geodatabase or an ArcSDE geodatabase. The pixels in the erase extent will change to NoData pixels after the operation.

Erasing a portion of a geodatabase raster dataset

The following code shows how to erase a portion of a geodatabase raster dataset:
[Java] 
static void erasePortionOfGDBRaster(IRasterDataset rasterDataset, IEnvelope
    eraseExtent)throws Exception{
    //IRasterDatasetEdit is needed for erase operation, Cast input IRasterDataset to IRasterDatasetEdit.
    IRasterDatasetEdit rasterDatasetEdit = new IRasterDatasetEditProxy(rasterDataset)
        ;
    rasterDatasetEdit.erase(eraseExtent);
}
