Re: Maths in ebooks

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

Seems to me it would not be hard to write a pandoc filter
that did this.  There's an example filter in the
pandocfilters repository that converts tikz images in
LaTeX to images.  Something like that could work here too,
only you'd match on 'Math' rather than 'RawBlock'.

https://github.com/jgm/pandocfilters/blob/master/examples/tikz.py

Filters can be written in Haskell or python (there are also
libraries to facilitate writing them in php and perl).
