1. Separate each page into two but don't do any text re-flow.
k2pdfopt -grid 2x1 -n- -ocr t -lang grc source.pdf
2. Same but with text re-flow
k2pdfopt -grid 2x1 -fc- -n- -f2p 0 -wrap -ocr t -lang grc source.pdf
3. Even larger text (50% larger with -mag 1.5)
k2pdfopt -grid 2x1 -fc- -n- -f2p 0 -wrap -ocr t -lang grc -mag 1.5 source.pdf
I've attached the results of these three methods for just page 5 of your PDF. You'll notice the text is selectable and searchable, unlike your original. |
Thank you so much, Willus. If I select to crop the borders, what I have to do? Because in this pdf file the borders are not exactly in the same position.
