Re: NVDA OCR with adobe image file

Hi all.

What happen in the file when you open the PDF with a browser? Firefox, Chrome, Edge and others browsers based in Chromium (Brabe, Opera, etc.) read PDF files, and in Some cases let that NVDA detect the graphics, and you can use the OCR pressing f11 for complete screen before of NVDA+r.

Regards.

Quentin,

 

Thanks for esponding!

 

As soon as I opened the file, I received no response from within the file. I pressed down-arrow and then up-arrow and I got the message Empty document as you suggested. I then pressed NVDA + r and got the following response:  

This document appears to be empty. It may be a scanned image that needs OCR or it may be a malformed document

 

The Result line shows no data at all.

 

Would it be possible to share this file with you and see what you observe about it? The content is Irish so I dont expect you to validate the text but, at least, you might be able to determine why the OCR is not happening.

 

All the best,

 

Cearbhall

Try pressing NVDA+r when you first open the file and get the message about it being blank.

Hi,

 

I have a scanned image in an Adobe .pdf file. I want to run NVDAs OCR over it. When I open the document in adobe Acrobat DC I get a message  that this is a blank document. I press F6 twice and press enter on the home button. Then I press NVDA+R and I hear recognising and below that result document but there is no text showing.

 

I know that this document is an image of scanned text because I can convert it using Abbyy Finereader.

 

All advice and instructions welcome!

 

All the best,

 

Cearbhall
