Technically, yes. You could use another OCR engine, or even improve the Tesseract engine already present in the addon. The thing is noncommercial OCR engines aren't very good, and improving tesseract is a hard task. For captchas, things are even harder, as they are built speciffically not to be solvable by a computer. Well, a computer makes them, so theoretically it should be possible, but hard. An easy thing to do would be to integrate webvisum into NVDA, providing the WebVisum guys would agree. Last time I wanted to make a Chrome WebVisum extension, I got no reply from them.

So much depends on resolution, color, etc. You can OCR a particular object on the screen by moving to it with Object Nav, and then doing NVDA+R on it. It by default scans the focused object, which might not be what you want to scan, but I'm getting off the original topic here. :)On 6/21/14, Stefan Moisei <vor_tex123@xxxxxxxx> wrote: Hi, I suggest you to find the manga in a downloadable format, e.g. pdf or jpgand then run it through a specialized OCR software like FineReader. The OCRengine used in the OCR addon is not as good as the commercial ones and theimage resolution is much worse on the screen than in a downloaded image, that's why I think it doesn't work. Plus the other things shown on the screen along with the manga. -----Original Message----- From: Amir Se nt: Saturday, June 21, 2014 10:36 AM To: nvda-addons@xxxxxxxxxxxxx Subject: [nvda-addons] ocr addon: can it scan the webpage Hi, i know the ocr addon cannot scan the capcha. that's not my point or question today, but i am wondering witch place will ocr works? on pdf documents? and webpages too? because, i want to read mangga and as you know, Mangga is the combination of texts and graphics. so cannot read using the normal browse mode.
