Hi BetterRed,
Thank you so much for your time and the use of Nitro : it does look pro
It seems to be more faithful to the original layout than Omnipage.
Nevertheless, I find the first files you sent me more accurate on the text recognition level.
... and both are not arguably better than the copy-paste of the original pdf OCR
Do you intend to publish an extensive comparison on pdf conversion ? I would be an interested audience.
Thank you again for sharing your results.
François
