Syntax

C++/CLI

Python

public void AppendGmlData( 
   Stream stream, 
   GmlData gmlData 
)

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

def AppendGmlData(self,stream,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.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Jpeg2000; 
 
 
public void AppendGmlDataStreamExample(FileStream inputStream, FileStream outputStream, GmlElement newData) 
{ 
   Jpeg2000Engine engine = new Jpeg2000Engine(); 
   //Read GML data in the input file 
   GmlData gml = engine.ReadGmlData(inputStream); 
   //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);
