Thanks that works, I'd already found that class, but I couldn't get it to work, because I didn't know what to pass as parameter.
FYI in tess-two the paramter is just defined as int level, which is any variable from TessBaseAPI.PageIteratorLevel. In my case instead of _constant_name_ I had to pass RIL_SYMBOL so tess would recognize single characters.
