Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Mrc; 
 
public void DeleteSegmentExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "PDFSegmentation.pdf")); 
 
   MrcSegmenter segmenter = new MrcSegmenter(image, RasterColor.FromKnownColor(RasterKnownColor.White), RasterColor.FromKnownColor(RasterKnownColor.Black)); 
   segmenter.SegmentImage(image, MrcSegmentImageOptions.Empty); 
 
   if (segmenter.EnumerateSegments(null) > 0) 
      segmenter.DeleteSegment(0); 
}
