AppendGmlData(Stream,GmlData) Method

Summary

Appends Geography Markup Language (GML) data to the specified JPEG 2000 data stream. This method is available in the Document/Medical Toolkits.

Syntax

C++

public void AppendGmlData(  
   Stream stream, 
   Leadtools.Jpeg2000.GmlData gmlData 
)

Public Overloads Sub AppendGmlData( _ 
   ByVal stream As Stream, _ 
   ByVal gmlData As Leadtools.Jpeg2000.GmlData _ 
)

public: 
void AppendGmlData(  
   Stream^ stream, 
   Leadtools.Jpeg2000.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.

   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)

   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)
