Yes, that came into my mind as well after the post. Guess I overlooked
that part as I get in touch with BSD licensed code so seldomly :-)

Yes I agree about the hOCR point. However, I think RTF will miss the
exact positioning for a PDF writer to layer the text behind the image
for the final PDF.

I'll now add a hOCR (HTML) parser for the PDF writer of ExactImage,
so that one can feed the formating stream with boundary boxes from
"any" hOCR program and obtain a searchable PDF.
