Suppose a pdf file has OCRed text. How can we convert it to a djvu file and pass the OCRed text to the djvu file?
Conversely, if exchange "pdf" and "djvu" in the above?
Thanks!
For pdf to djvu, use pdf2djvu. Just tested. It keeps OCR layer.
In other way around, I have not tested anything but according to this superuser post, this may work.
