See my pending patch set at:

    https://lore.kernel.org/linux-doc/e01fe9f9-f600-c2fc-c6b3-ef6395655ffe@gmail.com
    [PATCH v2 0/4] docs: sphinx/kfigure.py: Improve conversion to PDF

This uses Inkscape if it is available instead of ImageMagick.
No imagemagick nor librsvg2-bin is required.
As long as if you can trust Inkscape...

Good luck!

        Thanks, Akira
