[Question]Tesseract Limitations

[Nathan Pereira]

I am trying to read the following image(without the black bar that is from VS):

I have tried it several time and each time it returns nothing. I am using the code(below).

Am I just running into a limitation of the OCR or is there something else I could do to try and get it to work?

Thanks,

Nathan

I am using a .NET wrapper for tesseract-ocr 3.04 found here: "https://github.com/charlesw/tesseract"

Code I am running

`namespace` ORC
{
    class OCRFun
    {
        public void readData(Bitmap img)
        {
            try
            {
                using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
                {
                    using (img)
                    {
                        using (var page = engine.Process(img))
                        {
                            var text = page.GetText();
                            Console.WriteLine("Mean confidence: {0}", page.GetMeanConfidence());

                            Console.WriteLine("Text (GetText): \r\n{0}", text);
                            Console.WriteLine("Text (iterator):");
                            using (var iter = page.GetIterator())
