Appends Geography Markup Language (GML) data to the specified JPEG 2000 data stream. This method is available in the
Document/Medical Toolkits.
Syntax
| Visual Basic (Usage) |  Copy Code |
|---|
Dim instance As Jpeg2000Engine
Dim stream As Stream
Dim gmlData As GmlData
instance.AppendGmlData(stream, gmlData)
|
Parameters
- stream
- A 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()
Dim gml As GmlData = engine.ReadGmlData(inputStream)
gml.Data.Add(newData)
Dim frames As New List(Of Integer)
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)
outputStream.Write(buffer, 0, buffer.GetLength(0))
engine.AppendGmlData(outputStream, gml)
