	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
