[tesseract-ocr] Re: pdf -> searchable PDF

[wikinaut]

Andreas,

we track your issue now as new issue 
https://github.com/tesseract-ocr/tesseract/issues/660 . Please don't miss 
to follow the discussion there.

It looks, as if the main developers are really interested in finding and 
implementing a solution (in which I am also very interested in.)

Tesseract cannot rasterize PDFs. It is fairly straightforward to write a 
PDF like does, but very complex to rasterize one.

Programs like OCRmyPDF (which I develop) use Ghostscript, Tesseract and 
other tools to handle PDF to searchable PDF conversion.
