Zdenko:
I have following use case for tesseract C ++ 4.1 APi
I would like to read multi-page non-searchable pdf file as an input parameter
in PIX or PIXA, as output I would like to create searchable pdf file
my question to you
which tesseract C ++ Api Function I can call,
to read the multipage non-searchable pdf file in PIX or PIXA,
Do you have a little C ++ example about this topic
I mean, exactly like the command line: tesseract test.pdf output pdf
(test.pdf is multipage pdf file as input parameter)
