Here is my code:
string text = "";
string tessDataPath = ConfigurationManager.AppSettings["TessPath"];
using (var engine = new TessBaseAPI(@tessDataPath, @"eng"))
{
engine.SetVariable("tessedit_ocr_engine_mode", "0");
engine.SetPageSegMode(PageSegmentationMode.SINGLE_LINE);
engine.SetVariable("tessedit_char_blacklist", type.GetTesseractOptions
().Blacklist());
engine.SetVariable("tessedit_char_whitelist", type.GetTesseractOptions
().Whitelist());
engine.Process(imageFileName, false);
text = engine.GetUTF8Text();
}
I'm sending images which represent one or a few words on a single line, but
in the above code, the SetPageSegMode(..) method has no effect. On the
command line I can use:
tesseract.exe input.png result -l eng --psm 7 --oem 1
on the same images and see clearly better results on psm 7. Does anyone
know how to configure this option via the wrapper or is it just not
suppported?
Also, blacklists and whitelists are having no effect in the wrapper. Whilst
I understand that these are not supported in Tesseract 4 LSTM mode yet,
they should still work in 'Tesseract Only' mode right? I know the
SetVariable method works (as I see its effect on engine mode). Is there
another way of setting blacklists and whitelists through this wrapper?
Thanks
James
