Retrieve SVG images generated by MathJax with org-mode export

Question

I would like to export mathematical text to HTML with org-mode. The final output should be pure HTML with equation as images, preferrably svg. However, I would like to use MathJax instead of dvisvgm for its ability to interpret command definition such as

\( 
\newcommand{\glonk}{\int f(x)^\alpha} 
\)

How could I have MathJax calle by org-mode generate svg images?

Answer 1

Here is a partial answer.

If you have the org file below, you can export to HTML via ox-pandoc using the org-pandoc-export-to-html5-and-open function.

#+TITLE: Test Export using ox-pandoc
#+PANDOC_OPTIONS: mathjax:t

#+BEGIN_EXPORT html
<!-- https://stackoverflow.com/questions/45774826/svg-output-of-mathjax -->
<script type="text/x-mathjax-config">
    MathJax.Hub.Config({
        extensions: ["tex2jax.js", "TeX/AMSmath.js"],
        jax: ["input/TeX", "output/SVG"],
    })
</script>
#+END_EXPORT

* Equation

\( 
\newcommand{\glonk}{\int f(x)^\alpha} 
\)

\(
\glonk
\)

I am not sure how to extract those formulas rendered as SVG images into separate files which is the crux of the question.
