[poppler] Combine bounding box data and tiff to create pdf?

[Ed Porras]

In one message or another, Mark Ehle said something like this:
> I am using pdtotxt to extract text from pdf file in a digital newspaper archive I am creating for a local public library. So far, it's working great. But - I am using up a far amount of disk space and would like to figure out a way to create an OCR'd pdf from an image and the bounding box data. That way I would not have to store the PDF files as well as the images. Is there a way to do that?


Seems like you would want to store the PDF instead of the images. Anyway, you should look at Tesseract:

I haven't used it myself but, my understanding is, it'll embedded the OCR'd data into the PDF itself allowing searching, text selection, etc. from a PDF viewer.
