Re: OCRing pdfs using NVDA?

Hello Brian,

I've downloaded the portable version of the programme, plus all the ocr language files.

I'm ocr-ing a long document right now, but I must say teh programme is not all that accessible.

For example, if I rpess Alt or Alt+f to go to the menus, my son sees the menus on screen, but NVDA doesn't read anything, either in braille or in voice.

By exploring the screen with NVDA+7 (numpad 7, of course), I reach the options and, if I click on them, something happens, but not always.

I can open a file, but can't see the options, for examples.

If I move around with the mouse, on the other hand, things are shown and read out correctly.

Ctrl+Shift+c doesn't work here. To start ocr.ing I need to use the mouse.

Am I doing something wrong?

Using Windows 7 and latest NVDA Next snapshot.

Ciao,
Ollie

Dan,

I cannot speak to NVDA's OCR capabilities, but will offer a suggestion as a stand-alone. A company with the unfortunate name, these days anyway, of Tracker Software <https://tracker-software.com/> offers a free PDF viewer called PDF-XChange Viewer. When you land on the Tracker home page if you do an NVDA search for "free PDF" you'll land straight on the download link for PDF-XChange Viewer.

It has OCR capability for multiple languages built in to the free version and it has performed very well. I have used it to process image scanned documents up to several hundred pages in length, and with some not-so-great original scans, and what it can OCR with it's default settings is pretty amazing. Once an image scanned document that you know contains a lot of text has been opened in the program, simply hitting CTRL+SHIFT+C to run OCR on the file. You simply save it (standard windows File menu commands) after the OCR is done and you have the file with a permanent text layer added.
