There had been a request for a method similar to our IOcrZoneCharacters.GetWords method but to retrieve entire lines of text. Every character recognized by the OCR engine has a position. We can access this position through the position property of the OcrCharacter structure. This returns one or more OcrCharacterPosition enumerations members:

I wrote a quick little example that uses OcrCharacterPosition to write entire lines of recognized text at a time.

Code:
using (RasterCodecs codecs = new RasterCodecs())
{
   codecs.Options.RasterizeDocument.Load.XResolution = 300;
   codecs.Options.RasterizeDocument.Load.YResolution = 300;
   RasterImage image = codecs.Load(inputFile);
   using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Professional, false))
   {
      ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\OcrProfessionalRuntime64");
      using (IOcrDocument document = ocrEngine.DocumentManager.CreateDocument())
      {
         document.Pages.AddPage(image, null);
         document.Pages[0].Recognize(null);
         IOcrPageCharacters pageCharacters = document.Pages[0].GetRecognizedCharacters();
         for (int i = 0; i < document.Pages[0].Zones.Count; i++)
         {
            IOcrZoneCharacters zoneCharacters = pageCharacters.FindZoneCharacters(i);
            if (zoneCharacters != null)
            {
               foreach (var ocrCharacter in zoneCharacters)
               {
                  OcrCharacterPosition position;
                  position = ocrCharacter.Position;
                  if ((position & OcrCharacterPosition.EndOfLine) == OcrCharacterPosition.EndOfLine)
                  {
                     Console.Write(ocrCharacter.Code + "\n");
                  }
                  else
                  {
                     Console.Write(ocrCharacter.Code);
                  }
               }
            }
         }
      }
   }
}
