I have some code about OCR program using in C#.NET:

using System.IO;

using System.Drawing.Printing;

using Yiigo.Imaging;

using Yiigo.Imaging.Processing;

using Yiigo.Imaging.Recognition.OCR;



// Initialize OCR Engine

TesseractOcrEngine OcrEngine = new TesseractOcrEngine();

TesseractOcrEngine.Initialize();

TesseractOcrEngine.Translate(imageCollection, "application/msword", outputPath);

TesseractOcrEngine.Shutdown();

TesseractOcrEngine.Dispose();



// Cancel OCR in Progress

TesseractOcrEngine.PageProgressCancel = "True";



// Recognize Pages

 private void button6_Click(object sender, EventArgs e)

 {

      _ocrDocument.Pages.Recognize(null);

 

      string pdfFileName = @"C:\Ocr1.pdf";

      _ocrDocument.Save(pdfFileName, DocumentFormat.Pdf, null);

      System.Diagnostics.Process.Start(pdfFileName);

            }

                        

// Create a Searchable PDF

TesseractOcrEngine OcrEngine = new TesseractOcrEngine();

PDFGenerator PDFGenerator = new PDFGenerator(); 

PDFGenerator.Save = @"C: \Ocr1.pdf";

Or you can refer to its tutoial page about OCR http://www.yiigo.com/guides/csharp/how-to-ocr.shtml in C#.NET. I hope you success. Good luck.

I'm developing an OCR application using Tesseract engine but not MODI. In my opinion, tesseract ocr is more powerful and easier to use. there is a free online ocr tool http://www.online-code.net/ocr.html using tesseract, please have a try.

Sounds like the app doesnt have permission to read the path C:\ or the file was not found.

Try putting a breakpoint on it and examining the exception to see what specific IO error has occured?

Is this a console app or an asp.net webpage?

Hi -

Its a Web app. and the IO error is related to interop not related to permission.

Create a folder in C drive, and remove readonly access right ..
This will proceed but now it is throwing error on objModi.OCR,

Object is not initiliased...

Please reply, if you had overcome...

my code

rivate Sub ReadTextFromImage()

Dim _utput As String = ""
Dim objModi As MODI.Document
'MODI.Document objModi = new MODI.Document();
objModi = New MODI.Document()
objModi.Create("c:\omrtest\omrTest.tif")
objModi.OCR()
objModi.Close()

Dim _image As MODI.Image
_image = objModi.Images(0)

Dim _layout As MODI.Layout
_layout = _image.Layout
Dim _word As MODI.Word

For Each _word In _layout.Words
'_word = _layout.Words(i)
_utput = _utput & _word.Text
Next



End Sub
