Nicolas Goaziou corrected me and pointed out that the default is now MathJax, so I went off and tried things out. I tried with MathJax from the orgmode site, but I also downloaded the stable 1.0.x version (and the new otf fonts) and the beta 1.1 version (which already includes the new otf fonts). I tried it on the following org file (commenting/uncommenting options lines for the various runs: --8<---------------cut here---------------start------------->8--- #+OPTIONS: LaTeX:t ##+OPTIONS: LaTeX:dvipng ##+MATHJAX: align:"left" mathml:t ##+MATHJAX: align:"left" mathml:t path:"/home/nick/lib/mathjax/MathJax/MathJax.js" #+MATHJAX: align:"left" mathml:t path:"/home/nick/lib/mathjax/mathjax-MathJax-20e0cf6/MathJax.js" * Euler \[ \int_0^\infty e^{-x^2} dx = {{\sqrt{\pi}} \over {2}} \] \[ e^{i\pi} = -1 \] --8<---------------cut here---------------end--------------->8--- I've put the results of two runs, one with MathJax and one with dvipng, up at http://free.linux.hp.com/~nick/euler/euler-mj.html http://free.linux.hp.com/~nick/euler/euler-dvipng.html The different versions of MathJax all looked the same. The one I put up is the one that gets MathJax from the publicly available orgmode site, so if you just want to look at it, you don't have to install anything. There are two obvious differences: o the MathJax version has the equations centered, whereas the dvipng version has them flush left. I have not investigated why that is. o the dvipng version looks much better to my eye than the MathJax version. Of course, MathJax has advantages: it's scalable, so when you go to higher magnifications, you don't get the jaggies that the png images suffer. But I was wondering whether there is any way I can get prettier output from MathJax. Thanks, Nick
