Accessibility Support - Overview
RadPdfProcessing provides accessibility support of documents to users with disabilities. This allows many users with visual impairments to use screen readers and read such documents aloud. To enable proper vocalization, either through a screen reader or by some more direct invocation of a text-to-speech engine, the PDF document should support the following features:
The Accessibility Support is part of Telerik Document Processing, a
professional grade .NET library for creating and manipulating PDF, Word, XLSX and HTML files. To try it out sign up for a free 30-day trial.
Specifying the natural language used for text in a PDF document.
Providing textual descriptions for images or other items that do not translate naturally into text, or replacement text for content that does translate into text but is represented in a nonstandard way.
Specifying the expansion of abbreviations or acronyms.
The core of this support lies in the ability to determine the logical order of content in a PDF document, independently of the content's appearance or layout, through logical structure and Tagged PDF.
