Parameters

fillMethod
The fill method to check.

Return Value

True if fillMethod is supported by this IOcrEngine; otherwise, it is false.

To get all the fill methods supported by the engine, use GetSupportedNativeFillMethods.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Ocr; 
using Leadtools.Forms.Common; 
using Leadtools.Document.Writer; 
using Leadtools.WinForms; 
 
public void ZoneManagerExample() 
{ 
   // Create an instance of the engine 
   using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD)) 
   { 
      // Start the engine using default parameters 
      ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
 
      // Get the zone manager 
      IOcrZoneManager ocrZoneManager = ocrEngine.ZoneManager; 
 
      // Show all the zone types supported by this engine 
      Console.WriteLine("Hit enter to show the supported zone types"); 
      //Console.ReadLine(); 
 
      OcrZoneType[] zoneTypes = ocrZoneManager.GetSupportedZoneTypes(); 
      Console.WriteLine("Supported zone types:"); 
      Console.WriteLine("---------------------"); 
      foreach (OcrZoneType zoneType in zoneTypes) 
         Console.WriteLine("  {0}", zoneType); 
 
      // Shutdown the engine 
      // Note: calling Dispose will also automatically shutdown the engine if it has been started 
      ocrEngine.Shutdown(); 
   } 
} 
 
static class LEAD_VARS 
{ 
   public const string OcrLEADRuntimeDir = @"C:\LEADTOOLS22\Bin\Common\OcrLEADRuntime";
