The PDF accessibility checker (PAC 2) is the first tool that builds on the Matterhorn Protocol Berlin, August 8, 2013. The PDF Association today announced the release of the Matterhorn Protocol version 1.0. Thus, the practical implementation of the PDF/UA standards (ISO 14289) for creation and use of accessible PDF documents is being driven significantly. The PDF technology is an extensive and complex architecture for the representation of various documents. Without limiting this diversity, PDF/UA determines how the unrestricted accessibility can be ensured of content in PDF files for people with disabilities.
Reading order font using the PDF/UA standard defines requirements, barriers when accessing page contents, form fields, annotations, metadata and other elements of the PDF files to exclude. Thus, users who use special tools such as screen readers, special mouse or voice output and input, with electronic content in PDF documents can interact. The Matterhorn Protocol was developed to promote the introduction of PDF/UA in practice. It consists of 31 test sections, which are composed of 136 individual, precisely defined error conditions. This facilitates software vendors developing programs for the creation and review PDF/UA-compliant PDF files and forms. “” Each Matterhorn test section forms a special range of compliance requirements, such as such as setting the text language “or metadata”. Each error condition each define a specific test document, page, object or JavScript level. A part of the error conditions can be tested programmatically by a software, whereas a number of other error conditions must be checked interactively.
“A typical example of an condition of error in which human support is required, headings are not marked”. If an error condition such as alternate text for an image is missing”exists, can are determined automatically by a program. “The Swiss Foundation, available for free PDF accessibility checker (PAC 2) access for all” is the first tool that is based on the Protocol of the Matterhorn. It allows PDF files to PDF/UA conformance testing users. It was implemented by the xyMedia GmbH, which is a member of the PDF/UA competence center and actively participated in the drafting of the Matterhorn Protocol.
