# Re: [Zim-wiki] equation editor

Thanks. Unfortunately, the svg file doesn't look correct in my case (see attached the tex file, the png file originally created and the svg file after patching). I played around with the dvisgm options, but couldn't find a solution.

Best wishes,

Paulo

Indeed it works using dvisgm and it looks good, just change 3 lines in the plugin, see attached diff.

When I have some time I will try to make it an option in the plugin.

Regards,

Jaap

Perhaps replacing the dvipng by dvisgm
(http://dvisvgm.bplaced.net/) could work?

    Thanks, I had been looking in equationeditor.py file, but wasn't
sure how to add the -D option.

The reason I want to be able to change the resolution is to make
the image suitable to be used in printed documents, which
normally requires a dpi of 300. But that would result in a very
large image in the notebook. A solution for me (but perhaps not
so much for you) would be an option to resize the image display
in the notebook (like you can do with a normal image). The option
to use svg instead of png would be even better, perhaps also for

bigger, by passing the option "-D 192" to the "dvipng" command.
The modified version is here:

However this is not perfect, when I open the notebook on other
computers, the equations are too big.

Hi Jaap and other Zim devs,

The 'insert equation' function is a great function,
producing nice looking equations in Zim. However, the
resolution of the image (png file) that is generated by the
addon is fairly low. Is there a way to change the resolution
of the image? Or even better, would it be possible to add
the option to store the on-the-fly generaged image as svg
instead of png? This would provide in perfectly scalable
solution for any document.

Best regards

Paulo
