I also had to add code to handle the origin and direction to the new Write method in the extended class (see previous message):

	double ipp[ 3 ] = { 0 };
	if ( itk::ExposeMetaData< vcl_string >( dict, "0020|0032", tmpStr ) )
	{
		if ( sscanf( tmpStr.c_str(), "%lf\\%lf\\%lf", &ipp[ 0 ], &ipp[ 1 ], &ipp[ 2 ] ) == 3 )
		{
			for ( unsigned int i = 0; i < 3; i++ )
			{ 
				m_Origin[ i ] = ipp[ i ];
			}
		}
		else
		{
			// error
		}
	}
	double dir[ 6 ] = {1,0,0,0,1,0};
	if ( itk::ExposeMetaData< vcl_string >( dict, "0020|0037", tmpStr ) )
	{
		if ( sscanf( tmpStr.c_str(), "%lf\\%lf\\%lf\\%lf\\%lf\\%lf", &dir[ 0 ], &dir[ 1 ], &dir[ 2 ] , &dir[ 3 ], &dir[ 4 ], &dir[ 5 ] ) == 6 )
		{
			for ( unsigned int i = 0; i < 2; i++ )
			{
				for ( unsigned int j = 0; j < 3; j++ )
				{
					m_Direction[ i ][ j ] = dir[ ( i * 3 ) + j ];
				}
			}
		}
		else
		{
			// error
		}
	}
