Return Value
A handle to the Windows DDB this method creates.Converts a RasterImage object into a Windows device dependent bitmap (DDB). When this method is completed, there are two copies of the image in memory: the DDB and the original RasterImage. Freeing one will not affect the other.
NOTE: This method returns the data in an unmanaged handle. The caller is repsonsible for freeing the DDB's handle when it is no longer needed using the the DeleteObject Windows API, otherwise, your application will leak resources.
