What is libaccessodf-java
libaccessodf-java is:
AccessODF is an extension that can be used in OpenOffice.org Writer and in
LibreOffice Writer. It enables authors to find and repair accessibility issues
in their documents, i.e. issues that make their documents difficult or even
impossible to read for people with disabilities. This includes issues such as:
- insufficient colour contrast between text and background,
- missing text alternatives for images and other objects (such text
alternatives are necessary for blind users and other users of
text-to-speech software), - missing language identification for the document and for language changes
inside the document (language information is needed for conversion into
Braille and synthetic speech), - the use of proper Heading styles instead of big bold text to identify
headings (this enables document navigation based on headings), - the use of proper tables instead of visually mimicking tables by using tabs
or spaces, - the compatibility of images with DAISY, the de-facto standard for digital
talking books.
For each accessibility issue, AccessODF provides a description and repair
suggestions.
