Hello Mark, 

(I had good luck with eScape,  but it really isn't supported anymore.

I forgot to mention: I 'm working on Mac, and I found only Windows and Debian version of eScape.)

But are you saying that you saved in pdf then used calibre to convert to
epub from pdf and the formulas were dropped? 

No, I was happy only that in the pdf version from LO, the formulas were showed nice!  :)
I imported odt and html versions into Calibre.

I asked Werner Donne to see if odf2epub would work. The test resulted in
the tex being handled properly,  but the LO math appeared but only as a
text expression. Werner indicated that the isue was that epub readers
did not yet handle MathMl islands.

Ok, but I saw some epub and mobi math books with nice formulas. 
Even if I increase the font size the formulas were increased, too.
So it seems there are not simple image formulas.
Therefore has to be some kind of solution. I would be prefer an LO solution.

This is part of a continuing issue with OOo which incorporates MathML
but not in a way transparent to other applications. For example, you
really need additonal export macros to be able to convert an OOo doc to
Xhtml+MathML, as saving an OOo doc to html frmat converts equations to

So, as a result of the above,  if you save the doc with your equations
as LO Writer html, and then import into calibre, and then convert to
epub,  all equations will appear as you intended, because LO converts all
those equatins to images when saving to html.

It is true for the html version converted from LO, where the formulas are images and showed 
If I increase the font size in the browser, the formula picture is growing even though the quality 
will be worse.

But if I open this LO html version into Calibre, the result will be the following:
- some very simple pictures will be showed,
- most of the formula  pictures won't be showed.
The place of the formula is empty or sometime I can see instead of the formula an empty rectangle 
with a thin grey border.

So there are two problems with this solution:
- the most of the formula pictures vanish and
- if the formula is showed, it is a fixed size image.
 ( Mac OS X 10.6.6 and 10.6.7, LO 3.3.1)



I would like to convert LibreOffice document that contains Math formulas to ePub format.
If I save it as PDF, the formulas are showed fine.
If I open with Calibre the  .odt or .html (zip) files saved by LibreOffice, that everything is 
ok except the math formulas. They don't showed at all.
Tried to convert to ePub format with writer2epub extension, too. But there are not  formulas in 
the result.

How can I convert Math documents to ePub format from LibreOffice?

Thanks:  Zoli
