Cpdf Accessibility

Implement PDF/UA in cpdf

The Cpdf accessibility project extends the popular open-source PDF processing tool Cpdf to support PDF/UA (ISO 14289), the standard for accessible PDF. PDF/UA helps those with disabilities who use screen readers and other tools to navigate documents by tagging PDFs with metadata describing the logical structure of the content. Such metadata can also help all users by allowing reliable text re-flow, and better searching within documents. There is very little open-source tooling for accessible PDF at present, so this will represent a significant step forward. The work will involve adding functionality to Cpdf for the inspection and manipulation of existing PDF/UA files, and the creation of new ones from scratch. These tools will be useful to PDF/UA developers as well as to end users.
