Hello,
I try to implement tesseract-ocr with my powerpoint program in order to
recognize pictures.
I can extract a picture in powerpoint, but I want to extract its content.
Inside each picture is [myvariable] draw inside and I want to extract the
[myvariable] to use it later.
Bitmap image = new
Bitmap(@"C:\Users\vh610\AppData\Local\Temp\image.bmp");
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789"); // If digit
only
ocr.Init(@"E:\app\PPT\tessdata", "eng", false); // To use correct
tessdata
List<tessnet2.Word> result = ocr.DoOCR(image, Rectangle.Empty);
foreach (tessnet2.Word word in result)
Console.WriteLine("{0} : {1}", word.Confidence, word.Text);
The .dll was correctly implemented in the project and the program runs, but
on "ocr.Init" it gives an error.
The error is : Unable to laod unicharset file
E:/app/PPT/tessdata/\eng.unicharset
My Main project is located in E:\app\PPT\Source\ppt.sln and my tessdata is
in E:\app\PPT\tessdata where I have
grc.traineddata inside.
What am I doing wrong? Thanks
