![]() ![]() Users of popular assistive technologies such as NVDA, JAWS, VoiceOver, ZoomText, SuperNova, MAGic, and more are able to use their tool of choice and access information contained in PDF files. Familiar accessibility features found in formats like HTML such as alternative text for images, semantic elements to convey relationships and structure, labels for form controls, headings for tabular data, and a meaningful and logical content sequence are all fully supported by the PDF specification. The accessibility of any individual PDF file depends upon how well the author prepared the file for accessibility, and the accessibility of the experience for the end user depends on how well the PDF viewer application supports the accessibility features in the specification.Īdobe Reader takes advantage of all attributes of PDF files that have been properly prepared for accessibility. The PDF specification provides robust support for accessibility. Support for PDF accessibility dates back to 2001. With version 1.7, Adobe released control of the PDF specification to ISO, and in July 200-1:2008 was released as an International Standard. Subsequent versions of the PDF specification included additional features such as the addition of form controls, and included support for accessibility as the features were introduced. Tagged PDF also enabled other accessibility features in PDF viewers including text reflowing to allow users to increase text size without needing to scroll horizontally. In version 1.4 (2001) the concept of “tagged PDF” was added to the specification, which enabled users of assistive technologies such as Window-Eyes and JAWS to present document content to users without vision. Version 1.3 of the PDF specification in 2000 introduced features that enabled an underlying logical structure to exist for a PDF document. At this time, page content was represented as an image and there was no mechanism for users with disabilities to access the page content unless they could see it visually. ![]() And that reflow was similar.PDF was initially defined and made available as a specification in 1993. And based on my initial attempts to change some linguistic papers to epub before reading that any such engine is going to wreck formatting in a way not appropriate for something that isn't just words. This last comment is not based on personal experience as I don't have a device that reflows, but rather on comments from others who have stated that reflow is really only useful for novels or similar with no extras beyond writing. Since you referred to textbooks, I thought you might have more problems trying to read reflowed text, as any textbook that uses anything besides words (graphs, equations, etc etc) is unlikely to reflow properly anyway. Annotations are possible to make on bookmarks, but since you can't highlight, you can only make annotations per page not per selected text. You can use dictionary, but must type in word. ![]() Note 2: If you wanted reflow not just to be able to change the font size, but also for highlighting, dictionary use and annotations, then it's true you partially lose these functions on your Aura. To get around this you can:ī) tap to have the menu pop up and then close the menu, this also refreshes. Note: Right now there is a bug when using PDF that makes ghosting bad when moving around within a zoomed PDF. Although there is no reflow and therefore no way to change the "font size" per se, you do know that you can zoom them, right? When I make a PDF fit to screen LR, I find the text size very readable. Looking back at your post, I realised that you wanted to change the size to make your pdfs readable on your Aura. Therefore the Aura HD will become a 'keeper' and I will buy a cheap Tablet with PDF reflow for my textbooks. I sat and read a whole novel through last night (in epub) and the experience was superb, the quality and the clarity of the print was a delight to use. After reading all the above posts, perhaps I was being hasty in wanting to sell off my Aura HD. ![]()
