Re: Scanning and Reading PDF files


You may be doing what you want in terms of creating a scannable image in an inefficient way.  I don't know enough about PDF documents to know if it matters.  There are all sorts of image formats and it might be more efficient to scan a page or a document into an image rather than a PDF containing an image.  But I'll let others discuss whether it matters in terms of efficiency what you do. 
The reason you see text that NVDA can read in some PDF documents is that they are real text, not images of text.  You can store real text in PDF documents or images.
