Detailed Description

The implementation of AbstractTesseract4OcrEngine for tesseract OCR.

This class provides possibilities to use features of "tesseract" using tess4j.

Please note that this class is not thread-safe, in other words this Tesseract engine cannot be used for multithreaded processing. You should create one instance per thread
