Not enough information. All I can say: I tried it out and found it was working. I was not satisfied with the quality of this solution though. Also, I failed to make it working with any language rather then English. So, I don't see a way to help you unless you prepare and post a (shorted possible) code sample to manifest the problem.

                // Application Close here if I remove this code so..
                OCR.Init("D:\tessdata", "eng", false);
                // Appliction close here!
                List<tessnet2.word> r1 = OCR.DoOCR(bit, Rectangle.Empty);
                foreach (tessnet2.Word res in r1)
                {
                    textBox1.Text += res.Confidence;
                }

Hi,

don't used ocr from tessnet yet, but maybe you forgot the extension on initialzing ? would explain why it's crashing after Init() without really doing something.

I think tessdata is some "dictionary" of english words, I'm right?

C#

OCR.Init("D:\tessdata.JPG\.DAT\some kind of extension", "eng", false);

With Best Regards

Solution 5

I uninstalled the tesseract-ocr 3.X, and cleared the registry and the environment path about it. After the system reboot,it's ok now.
