PDF/a Show Case

Intro

Its’s possible to render the output as a valid PDF/a document.

TypoScript

Be sure to disable all header data, to ensure that all HTML header output is disabled. Some variables on page properties are used to fill the meta data.

    pdfpage {

            }

PHP

A custom PHP class is needed to override the TCPDF constructor, to be able to set the pdfa parameter to true.
