mathjax-node with sre and svg2png

[Tim Arnold]

hi,

I would like to use the mathjax-node distribution but with speech rule engine and svg2png capabilities.

I see that I can use one or the other (mathjax-node-sre or mathjax-node-svg2png).

Is it difficult to combine those? Can you point me to instructions or an article about it?

I'm rewriting code from the old version of mathjax-node which had the capabilities.

thanks,

--Tim

Hi Tim,

mathjax-node-sre can be used as both a pre and post processor so that gives you two way of combining them.

I haven't maintained mathjax-node-svg2png much recently because I don't use this kind of approach in production (it's usually too inefficient, e.g., duplication, hooking in zopfli etc); also phantomjs is dead.

However, there's Google's puppeteer library now (i.e., node APIs for Chrome headless) so png conversion is rather simple -- here's an 8 line example I cooked up for a workshop recently.

Best,

Peter.

Hi Peter,

Thanks for that info. I will use mathjax-node-sre and wire up that svg2png function to get the pngs. Thanks for that example!
