I understand. BTW, though Github is acquired by Microsoft, it's still
free and the top 1 free open source software development and version
control platform in the world.

In the source, you says the following:

;;; - imagemagick to modify images and svg support

According to my experience, imagemagick will rasterize the vector
image. If you want to obtain a lossless vectorized image conversion
support, I suggest to use rsvg-convert and inkscape for svg support
[1]:

$ rsvg-convert -f pdf -o chemical_potential.pdf chemical_potential.svg
$ inkscape chemical_potential.svg --export-pdf=chemical_potential.pdf

Thank you for your explanation. Let me give it a try and then
comment/feedback further.
