The current method is based on input from [~lfcnassif] IIRC... Improvements to {{AUTO}} are a separate issue, though. Are you ok with this choice default? I just opened TIKA-3264 to capture that discussion. was (Author: talli...@mitre.org): [~adidier], y, that's exactly the type of refinement we'd want to consider adding to {{AUTO}} mode.

We did this initially > because of concerns (well, reality) of crazy resource consumption for some > PDFs that can have thousands of images per page that are stitched together to > make a reasonable composite. > Since then, we've added option 2, which renders each page and then runs OCR > on that composite image rather than running OCR on each inline image...so > we'll only call tesseract once per page. Second, we've added an 'auto' mode > that runs OCR only on pages that didn't have much text extracted. While > there is plenty of room for improvement in the 'auto' heuristic, I think we > should move to running OCR automatically on PDFs as default in 2.0.0. > Under this proposal, users will now have to disable OCR if they have > tesseract installed but don't want to run it on PDFs. > This will be a breaking change, and we'll make sure to document it early and > often in the "Breaking Changes" sections of the readme.txt. -- This message was sent by Atlassian Jira (v8.3.4#803005)
