However, this does not mean that there is no problem. This is obviously not a very user-friendly thing to do generally, and can be a significant inconvenience for people who need higher levels of page magnification.įortunately, dedicated screen magnifiers such as ZoomText, MAGic and SuperNova all ignore the PDF link zoom attributes (or treat them as if they were set to inherit). If you don’t set your zoom attributes to inherit, when you click an internal link (including table of contents links or bookmarks) the page is likely to shrink, sometimes dramatically so. Acrobat typically generates links with their zoom attributes set to Fit Page, Fit Width or Custom, depending on the page zoom setting at the time the link is created. Unfortunately, this is not the default for links created in Acrobat. Doing so will ensure that the user’s page size or zoom setting will be preserved when the link is clicked. In short, except in a few very rare cases, all internal links in PDFs should have their zoom attributes set to Inherit. Setting internal link zoom settings to inherit This post looks at one further aspect of accessible PDF links that document authors should pay attention to, namely link zoom settings. Our blog post Creating accessible links in PDFs describes several of these techniques in detail. In our Accessible PDFs from Acrobat training course we set out 10 must-know PDF accessibility linking techniques.
