Are you sure you want to prevent the correct viewing of your document in stock versions of Chrome, IE, and Opera?

Yes, I know there are browser plugins and hacks like MathJax that can fix this, but…ech.

If you’re also targeting PDF, most XSL-FO processors don’t support MathML, either.  Last time I checked, only Antenna House did.  I see that they have included it in the commercial version, but it’s still a paid add-on for the Lite version:

I found this quite useful for PDF output:

http://pmml2svg.sourceforge.net/


This XSL stylesheet converts MathML to SVG. SVG can be then inserted into the XSL-FO for PDF output or converted to PNG for HTML.


If you want to use inline formulas, you'd need a small hack to pass the baseline shift generated by pMML2SVG (which is stored in the generated SVG) into the XSL-FO attribute. I have a patch for that somewhere; I'll dig it up if you're interested.

Regards,
Alexey.



When I created the f/Calc manual, I built a bit of Makefile hackery to turn LaTeX fragments into PNG for the HTML version and PDF for insertion into the PDF version by the XSL-FO processor:

http://fcalc.net/manual/
http://fcalc.net/manual.pdf

I think the result is fairly seamless, and it works on all browsers, going back to ancient days.

If you want, I can dig up the recipe.  It’s simple enough to be quickly reinvented.  I’d post it now, but I don’t have the code on hand where I am now.
