__property OSGeo ::FDO ::Expression ::DataValue* OSGeo::FDO::Raster::get_NullPixelValue | ( |  | ) |
Gets the pixel value that represents a NULL value in the available raster stream. Remarks: The Null Pixel Value is Data Model dependent. The value of the Null pixel will change depending on which data model is set. If the client application changes the Data Model using SetDataModel(RasterDataModel* datamodel) a subsequent call to GetNullPixelValue will need to be made in order to determine the valid Null value for the current data model. Returns: Returns the DataType value that can be used to identify the Null value.
