MathJax equations are not rendered

[OpenFoam-User]

Hello

I have tried your example here: https://github.com/yeslogic/prince-scripts/tree/master/compatibility/MathJax
(I have used your html input, and downloaded also the compat.js file)

I have Prince 14.2 installed on Ubuntu 20.04.

When I convert it using the following command:

prince --javascript input.html -o output.pdf

The resulting pdf doesn't render Mathjax:

Thanks

Hi @SignificantCell2,

If I recall correctly, version 14.2 did not yet support MathJax 3. Prince should have printed an error, something like:

MathJax(?): undefined value is not an object

Could you try one of the latest builds?

Hi thank you for your reply.
You're right, I get it working with the latest builds of Prince!
But the end result (the equation) are not selectable in the output PDF document.

That's because the example uses the SVG output processor, and not the CommonHTML one. Replacing:

<script id="MathJax-script" src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js"></script>

with

<script id="MathJax-script" src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js"></script>

should make the equations selectable (for a certain definition of selectable).
