Re: equation editor

 

Hi Jaap,

I had already tried that like below (not sure that is the correct way)

dvipngcmd = ('dvisvgm', '-o', '-n')

But this results in an error "An error occurred while generating the image.
Do you want to save the source text anyway?"

I'll see if I can install/compile the new version

Regards

Paulo
