Re: [libreoffice-users] convert Math to epub

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.

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.

It is true for the html version converted from LO, where the formulas are images and showed 
correctly.
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)
