Is there somebody working on exporting documents to html and keep working formulas ?

The conversion to .gif images is a loss of information, uselessly makes a lot of small files that look bad on the web.

One must export again to make any changes...

Why isn't html export made to mathml code? Has anyone written a macro? Will future version of libreoffice export that way?

I just tried Libre Office Version (Build ID: e29a214) and if you export a document using export/ xhtml from the file menu, formulae are exported as MathML.

Thank you very much, BUT it doesn't work!!! I tried some very simple formulae (using Dmaths that I recommend): %alpha +{5}=sqrt{x+{1}}

left lbrace stack{{ x+{1}={2} } # { y+x={3} }} right none

S lsub{32}lsup{16}rsup{{2}"-"}

The result looks like this in LibreOffice (latest version)


but it works only on firefox but on chrome and on IE it looks like that:

image description

The mathml isn't at all interpreted and a space there is a space for an image that doesn't show. I had a look on the .html file generated and found and embedded image via data URL scheme. The problem might be that the image doesn't have a type like png in <img src="data:image/png;base64,.... but instead you get a star like in <img src="data:image/*;base64,...

I tried gif, png, jpg, nothing worked. Anyway, I want mathml to work so that the html file can be modified and not an image (embedded or not). That image is only making the html code longer.

My question now is: is it possible to get only mathml and to have it work on chrome and IE? How can I get in touch with the developing team?
