---------------------------------
Hi Luis [~lfcnassif]
Your main goal is "to ocr scanned docs". Can I assume you are happy using
Tesseract, and know how to use it directly?
I OCR'd 25M images as described in [https://github.com/rleir/c7atess] . My
biggest challenge was to pre-process the TIFF images to improve contrast. I
never converted them to PDF, and I did not use Tika. Is Tika helpful in
achieving your goal? Not meaning to detract from Tika, I find it excellent for
other purposes.
> OCR on PDFs should "just work" out of the box

> URL: https://issues.apache.org/jira/browse/TIKA-2749
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Major
>
> There are now two different ways (with various parameters) to trigger OCR on
> inline images within PDFs. The user has to 1) understand that these are
> available and then 2) elect to turn one of those on.
> I think we should make OCR'ing on PDFs "just work" perhaps with a hybrid
> strategy between the 2 options. Users should still be allowed to configure
> as they wish, of course.
