Re: NVDA does not support line breaks in PDF files


You are probably thinking of the number of characters per line setting.  Web pages generally don't have line breaks except where the writer specifically puts one in the text.  But browsers determine the length of lines in general by the size of the window from left to right.  In browse mode, the line length is determined by the screen-reader and I don't think has any relation to the size of the reader.  So you have the ability to set the lines to your desired length. 
But PDF documents may have regularly occurring line breaks.  I don't know.  
NVDA uses browse mode and evidently doesn't understand the character used by PDF documents for line breaks.  You can change the length of lines at present by working with the characters per line setting.  This won't follow actual line breaks but may make the document more as you want it.

I cannot answer this definitively but I have encountered similar problem on web pages and the solution then was to change some of the document layout properties of NVDA using NVDA Control and D.

Unfortunately I have gone back to a web page and examined the document layout properties pane and I cannot immediately identify which was the setting I changed at the  time.

Someone else may remember what property I am thinking of.

I hope I am not sending people off on a wild goose chase.

Subject: [nvda] NVDA does not support line breaks in PDF files



When reading a PDF with NVDA in Adobe Reader, I find that NVDA does not honor line breaks. To illustrate, let's say part of the PDF looks like this:


Line one

Line two

Line three


When reading this PDF with NVDA, I would get:


Line one Line two Line three


Such is the basic nature of the problem I am facing. Now for some auxiliary observations:

1. When exporting the PDF as a text file, the text file ends up having correct line breaks.

2. When reading the PDF with JAWS, line breaks are correctly presented.

3. The problem occurs on three machines, two of them running Windows 10, the third running Windows 7, with both NVDA 2019.1 and current beta of 2019.2.

4. The problem persists after uninstalling and then reinstalling Adobe Reader.

5. The problem persists after repairing the Adobe Reader installation.

Since Adobe Reader itself exports the line breaks correctly, and since JAWS is also seeing them as expected, the problem is clearly with NVDA.
