OCRing existing PDF

[robert.j...@icloud.com]

Hello,

I need to OCR several PDF, what command line can I use to batch (French text)?

Can you point where I can find this information in the tesseract manual.

Thanks,

Robert Richard

Tesseract does not take pdfs as direct input. You have to convert pdf to images and provide that to tesseract.

However there are many 3rd party applications which take pdf as input and have tesseract as backend to do OCR.

The ones I have personally tried are

VietOCR

http://vietocr.sourceforge.net/usage.html  

gImageReader

https://github.com/manisandro/gImageReader  

OCRMYPDF

https://ocrmypdf.readthedocs.io/en/latest/
