HOW TO: Apply Redaction Annotation to Image and then OCR and save output as redacted searchable PDF - Load, Annotated, Burn, and OCR an image and save as image over text enabled PDF

      private RasterImage BurnImage()
      {
         RasterImage image = imageViewer.Image;
         annAutomationManager.RenderingEngine.RenderOnImage(annAutomation.Container, image);
         annAutomation.Container.Children.Clear();
         return image;
      }

      private void DoOCR(RasterImage image, string fileName)
      {
         using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
         {
            ocrEngine.Startup(null, null, null, null);

            PdfDocumentOptions pdfOptions = ocrEngine.DocumentWriterInstance.GetOptions(DocumentFormat.Pdf) as PdfDocumentOptions;
            pdfOptions.ImageOverText = true;
            ocrEngine.DocumentWriterInstance.SetOptions(DocumentFormat.Pdf, pdfOptions);

            using (IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument())
            {
               ocrDocument.Pages.AddPage(image, null);
               ocrDocument.Pages.Recognize(null);
               ocrDocument.Save(fileName, DocumentFormat.Pdf, null);
            }
         }
      }
