I've been using
https://www.codecogs.com/latex/eqneditor.php
in order to make the LaTeX to replace poor quality JPGs, GIFs, PNGs, etc. of equations with an SVG image.
Working well, but when I import the SVG into a epub, I get what looks like a lot of vector paths. The result is good, but if I have to correct something, I have to start over at codecogs.
Is there a way to save the SVG differently in the epub-- preferably as the 'raw' LaTeX -- so that I could just paste it into codecogs, fix, and resave?
