svg Scalable Vector Graphics. This creates a
single SVG file, without embedded fonts, for
every page of output. It is recommended to
install the Century Schoolbook fonts, included
with your LilyPond installation, for optimal
rendering. Under UNIX, simply copy these
fonts from the LilyPond directory (typically
‘/usr/share/lilypond/VERSION/fonts/otf/’)
to ‘~/.fonts/’. The SVG output should be
compatible with any SVG editor or user
agent. There is also an option svg-woff
(below) for use of woff font files in the SVG
backend.
