)

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.
gmlData: GmlData object containing the GML information being appended.

Private Sub AppendGmlDataStreamExample(ByVal inputStream As FileStream, ByVal outputStream As FileStream, ByVal newData As GmlElement)
   Dim engine As New Jpeg2000Engine()

   ' Read GML data in the input file
   Dim gml As GmlData = engine.ReadGmlData(inputStream)

   ' Add the new gml element data
   gml.Data.Add(newData)
   Dim frames As New List(Of Integer)
   ' extract all inputfile frames
   Dim fileInfo As Jpeg2000FileInformation = engine.GetFileInformation(inputStream)
   For i As Integer = 0 To fileInfo.Frame.GetLength(0) - 1
      frames.Add(i)
   Next i

   Dim buffer() As Byte = engine.ExtractFramesMemory(inputStream, frames)

   ' write buffer to the output stream
   outputStream.Write(buffer, 0, buffer.GetLength(0))

   ' add all GML data
   engine.AppendGmlData(outputStream, gml)
End Sub

public void AppendGmlDataStreamExample(FileStream inputStream, FileStream outputStream, GmlElement newData)
{
   Jpeg2000Engine engine = new Jpeg2000Engine();
   //Read GML data in the input file

   //Add the new gml element data
   gml.Data.Add(newData);
   List<int> frames = new List<int>();
   //extract all inputfile frames
   Jpeg2000FileInformation fileInfo = engine.GetFileInformation(inputStream);
   for (int i = 0; i < fileInfo.Frame.GetLength(0); i++)
      frames.Add(i);
   byte[] buffer = engine.ExtractFramesMemory(inputStream, frames);
   //write buffer to the output stream
   outputStream.Write(buffer, 0, buffer.GetLength(0));
   //add all GML data
   engine.AppendGmlData(outputStream, gml);
