Tagging Graphics

Question

First: This is somewhat a follow-up question to Tagging of Included Graphics (because I forgot to ask the following in the other question :-().

I (now) know how to use the alt key to give a proper written description of externally inserted graphics in a LaTeX document, but what if I have a PSTricks drawing?

My first thought was to somehow put an 'empty' image inside the drawing using \includegraphics and then use the alt key to give a proper description of the drawing. However, this approach doesn't seem right at all.

P.S. I use LuaLaTeX for all my documents these days.

Answer 1

Something like this??? Needs lualatex --shell-escape ...

\begin{document}

\begin{externalDocument}[
    compiler=lualatex,
    crop,
    code=false,
    grfOptions={alt=my wonderful image}]{exa}
\DocumentMetadata{} 
\documentclass{article}
\pagestyle{empty}
\usepackage{pstricks-add,xcolor}
\begin{document}
\begin{pspicture}(-5,-5)(5,5)
  \psaxes{->}(0,0)(-4,-4)(4,4)[x,-90][y,0]
\end{pspicture}
\end{document}
\end{externalDocument}

\end{document}
