Size of PDF document is computed from PDF Points // and the rendering resolution specified by `textRecognizer.PDFRenderingResolution` (default 300 DPI) Size pageSize = textRecognizer.GetPageSize(pageIndex); // Add area of interest as a rectangle at the top-right corner of the page textRecognizer.RecognitionAreas.Add(pageSize.Width / 2, 0, pageSize.Width / 2, 300); // Add area of interest as a rectangle at the bottom-left corner of the page, // and indicate it should be rotated at 90 deg textRecognizer.RecognitionAreas.Add(0, pageSize.Height / 2, 300, pageSize.Height / 2, AreaRotation.Rotate90FlipNone); // Now, you can get recognized text for further analysis as a list of objects // containing coordinates, object kind, confidence. OCRObjectList ocrObjectList = textRecognizer.GetOCRObjects(pageIndex); foreach (OCRObject ocrObject in ocrObjectList) Console.WriteLine(ocrObject.ToString()); // ... or you can save recognized text pieces to file textRecognizer.KeepTextFormatting = false; // save without formatting textRecognizer.SaveText(outputDocument, pageIndex, pageIndex); // Open the result file in default associated application (for demo purposes) Process.Start(outputDocument); } catch (Exception exception) { Console.WriteLine(exception); } } Console.WriteLine(); Console.WriteLine("Press any key..."); Console.ReadKey(); } } }
