If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page.

The implementation of IOcrEngine.This class provides possibilities to perform OCR, to read data from input files and to return contained text in the required format. Also, there are possibilities to use features of "tesseract" (optical character recognition engine for various operating systems).
The implementation of AbstractTesseract4OcrEngine for tesseract OCR.This class provides possibilities to use features of "tesseract" CL tool (optical character recognition engine for various operating systems). Please note that it's assumed that "tesseract" has already been installed locally.
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
