public void AppendGmlData( 
   Stream stream,
   GmlData gmlData
)

'Declaration
 
Public Overloads Sub AppendGmlData( _
   ByVal stream As Stream, _
   ByVal gmlData As GmlData _
)

'Usage

Dim stream As Stream
Dim gmlData As GmlData
 
instance.AppendGmlData(stream, gmlData)

public:
void AppendGmlData( 
   Stream^ stream,
   GmlData^ gmlData
)

Parameters

stream: A System.IO.Stream containing the JPEG 2000 file data to which the GML data is being appended.
