Introduction
With the help of the jEuclidhttp://jeuclid.sourceforge.net/usage.html library, the Apache FOP can render MathML formulas directly from XML code.
Unfortunately, at the moment this doesn't works. There were
some changes in the jEuclid library which make it incompatible with the Apache FOP. But stay tuned, I'm working on it :-).
Meanwhile, you can transform MathML code with jEuclid directly on the commandline and embedd the resulting image in
your XML files.
In any case, it is also a little bit complicated to write MathML-equations manualy. To simplify this task, there are a lot of
MathML editors outside which can be used to create MathML code.
Once you have created MathML-code, it is simple to transfer it to SVG with jEuclid
into an image format. It is recommended that you use the SVG format: this is the only vector based format jEuclid can
produce. Vector based formats has the advantage that they can scaled without loss of quality .
This SVG can then used in the st stylesheets like any graphic.
OpenOffice as MathML Editor
OpenOffice has a very comfortable equation editor on board. You can invoke it via the Insert / Object / Formel
The screenshots are showing the german version of OpenOffice menu:

Once the formula is is complete, you can export into the MathML format with a right click on it, using the point "Save as"
in the content menu:
![]()

With the mml2xxx command in the bin-directory of the jEuclid distribution, the MathML code can converted
to SVGThe mml2xxx command seems to have some problems with paths, for me it just works when I put the input file in
the same directory where the script resists:
mml2xxx entropy.mml entropy.svg image/svg+xml
where entropy.mml is the with OpenOffice produced MathML file and entropy.svg the output file in SVG.
The parameter image/svg+xml tells jEuclid that the output should be in SVG formatjEuclid can produce some
more image formats: PNG, JPEG, X-PNG VND.WAP.WBMP and BMP .
The result can be embedded in an st XML file:
<img>entropy.svg</img>
