using Leadtools.Codecs; 
using Leadtools.Forms.Common; 
using Leadtools.Ocr; 
using Leadtools.Drawing;

   using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD)) 
   { 
      // Start the engine using default parameters 
      ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
 
      IOcrSpellCheckManager spellCheckManager = ocrEngine.SpellCheckManager; 
 
      // Add the following words to the English dictionary 
      string[] newWord = { "OMRing", "Binarization" }; 
      spellCheckManager.AddUserWords("en", newWord); 
 
      // Now perform other OCR functions here 
 
      // Shutdown the engine
