Example
C#
using Leadtools; 
using Leadtools.Codecs; 
 
 
public void CodecsJbig2OptionsExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1.tif"); 
   RasterImage srcImage = codecs.Load(srcFileName); 
 
   // Save as JBIG2 with Template #3 
   codecs.Options.Jbig2.Save.RemoveMarker = true; 
   codecs.Options.Jbig2.Save.RemoveHeaderSegment = true; 
   codecs.Options.Jbig2.Save.RemoveEopSegment = true; 
   codecs.Options.Jbig2.Save.RemoveEofSegment = true; 
   codecs.Options.Jbig2.Save.ImageTypicalPredictionOn = true; 
   codecs.Options.Jbig2.Save.ImageTemplateType = 3; 
   codecs.Options.Jbig2.Save.ImageQualityFactor = 0; // Lossless image compression 
 
   codecs.Save(srcImage, Path.Combine(LEAD_VARS.ImagesDir, "jbig2.jb2"), RasterImageFormat.Jbig2, 1); 
 
   // Clean up 
   srcImage.Dispose(); 
   codecs.Dispose();
