using Leadtools; 
using Leadtools.Codecs;

using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
public void ExtractXMPMetadataExample() 
{ 
   // The source file 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Leadtools.pdf"); 
   string xmlFileName = Path.Combine(LEAD_VARS.ImagesDir, "XMP.xml"); 
   string dstFileName = Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg"); 
 
   using (var codecs = new RasterCodecs()) 
   { 
      try 
      { 
         //Extract XMP Metadata & save it to a XML file. 
         codecs.ExtractXMPMetadata(srcFileName, xmlFileName); 
 
         /* 
         Add/Update Metadata in the XML file using any XML parser(if needed). 
         */
