Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Jpeg2000; 
 
 
 
public void SaveCompositeStringExample(byte[] xmlData) 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   // Load a JPEG 2000 image 
   Jpeg2000Engine engine = new Jpeg2000Engine(); 
   List<CompositeJpxImages> images = engine.LoadComposite(codecs, Path.Combine(LEAD_VARS.ImagesDir, "image1.jpx"), 0, CodecsLoadByteOrder.BgrOrGray); 
 
   engine.ResetEngineBoxes(); 
 
   GtsoBox gtsoBox = (GtsoBox)(engine.ReadBox(Path.Combine(LEAD_VARS.ImagesDir, "image1.jpx"), Jpeg2000BoxType.GtsoBox, 0)); 
   engine.SetBox(Jpeg2000FileFormat.LeadJpx, gtsoBox); 
   //Save the image in JPX file format 
   engine.SaveComposite(codecs, Path.Combine(LEAD_VARS.ImagesDir, "Test.jpx"), images, Jpeg2000FileFormat.LeadJpx, 24, 5); 
   //Append an XML box 
   XmlBox xmlBox = new XmlBox(); 
   xmlBox.Data = xmlData; 
   List<XmlBox> xmlBoxes = new List<XmlBox>(); 
   xmlBoxes.Add(xmlBox); 
   engine.AppendBoxes(Path.Combine(LEAD_VARS.ImagesDir, "Test.jpx"), xmlBoxes); 
   // Clean up 
   foreach (CompositeJpxImages image in images) 
   { 
      image.ColorImage.Dispose(); 
      image.OpacityImage.Dispose(); 
      image.PreOpacityImage.Dispose(); 
   } 
   codecs.Dispose();
