Chapter 1: Overview
Adobe Reader is free to download from Adobe Systems Inc. It is an application you use to open and read portable document format (PDF) files and includes some useful accessibility features and some useful keyboard commands.
There are four main types of PDF document with each type providing different levels of accessibility to their content
Types of PDF documents and their accessibility
- Tagged documents: Authors can add tags to help mark out structure and content in PDF documents, for example, authors can add alternative text to images. Authors who do add tags to their documents will find their documents are fully accessible and can be read by SuperNova
- Untagged documents: Authors, who create documents without adding tags, are creating untagged documents. When Adobe Reader detects an untagged document, it examines the document and automatically adds temporary tags to help give the document structure. The accessibility of an untagged document can vary considerably.
- Image only documents: Authors can add images to a document, which includes adding an image of the printed page. This type of PDF document is only accessible by converting the document to text using OCR technology, such as that provided by Dolphin EasyConverter.
- PDF forms: Authors, who create PDF forms, must ensure their document is properly structured and tagged. Authors must ensure the fields have correct labels and the TAB sequence is logical. PDF forms that follow these simple rules will be accessible.
SuperNova Version 13 includes support for Adobe Reader. SuperNova also includes additional inbuilt features to make it easier to read accessible PDF files opened within this application.
