SVGTeX is a forked project to render SVG from TeX equations, on the server, thanks to the MathJax lib and PhantomJS. It's used on LinuxFr.org.
Install PhantomJS 1.9, then run these commands:
git clone https://github.com/linuxfrorg/svgtex cd svgtext git submodule update --init phantomjs main.js
Below, you will find the original README from svgtex.
Using MathJax and PhantomJS to create SVGs on server side with minimum overhead.
MathJax is a great tool! Why not use it on a server side too? To avoid loading the whole phantomjs and MathJax into memory with every call, the service is exposed via HTTP.
Detailed usage instructions are on the GitHub wiki. For quick-start instructions, keep reading.
Then, start the server:
$ phantomjs main.js Loading bench page index.html Server started on port 16000 Point your browser at http://localhost:16000 for a test form.
Try it out by pointing your browser at http://localhost:16000/, and using the test form to enter an equation in either TeX or MathML.
Or, from a different console, use curl:
$ curl localhost:16000/?q=x <svg xmlns:xlink="http://www.w3.org/1999/xlink" style="width: 1.34ex; height: 1.099ex; ...
Loading MathJax from the CDN vs locally
By default, this loads MathJax from the MathJax CDN. That means that the server uses an internet connection, and it loads MathJax once, as the server is started.
To use a local version of MathJax instead, first download and extract MathJax
mathjax subdirectory (or wherever else you would like):
wget https://github.com/mathjax/MathJax/zipball/v2.3-latest -O mathjax.zip unzip mathjax.zip mv mathjax-MathJax-* mathjax
Then uncomment the <script> element in index.html that refers to this local version, and comment out the one that loads from the CDN.
