The MathJax Library
The MathJax add-on library is provided as part of the installation of PTC Arbortext Layout Developer. The library is installed within the MathJax sub-folder of the libs folder. The library contains three files and a sub-folder of MathJax scripts:
mathjax.3ns — a Layout Developer namespace of protected and encrypted tags which includes the ‘createGraphic’ function.
mathjax_scripts.3ns — another Layout Developer namespace which contains tag versions of the contents of the mathjax_scripts folder. This namespace is linked to the mathjax.3ns namespace. If this file is deleted, it will be recreated from the contents of the mathjax_scripts sub-folder, allowing updates to occur. Care must be taken if the library is kept in a write-protected location such as the Programs folder in Windows as this will cause errors.
libcfg.js — a JavaScript add-on library configuration file to set up the library in Layout Developer’s Library menu. This file sets the Library menu item to allow the user to enable MathJax in their template.
mathjax_scripts — a sub-folder containing the MathJax library JavaScript files. These files are a copy of those found in the MathJax distribution.

We have tested Layout Developer using the version of the MathJax library we provide. Using a different version is not explicitly supported and so changing the contents of the mathjax_scripts folder is done entirely at the user’s own risk.
