The Cairo backend has many advantages for SVG, but I didn't expect one
of this kind.
This seems to be a limitation of the svg backend that has been there
ever since. "lilypond-book-preamble.ly" explicitely switches to the eps
backend and does not workd (i.e. create cropped images) with the svg
backend.
Sorry, I cannot describe it more deeply, but it has been discussed here:
https://lists.gnu.org/archive/html/lilypond-user/2016-06/msg00133.html
With this code:
\version "2.23.12"
\include "lilypond-book-preamble.ly"
{ c' }
Compiling the file as
lilypond --svg file.ly
I get cropped SVG output.
What you are describing used to be a limitation of
lilypond-book-preamble.ly,
but no longer is. It got waived at some point in Han-Wen's heavy backend
refactorings (removing the eps backend among others). Well, it's true that
the primary motivation for these refactorings was better Cairo support.
So the limitation is gone now, even without Cairo. That being said, for the
other reasons I mentioned earlier, it is still a very good idea to use Cairo
for SVG output.
Best,
Jean

The new cairo backend could be the ultimate solution to all that. Thanks a million to everyone who has worked on that feature! Cheers, Klaus

Have anyone considered that? I don't think so — how would it bring us closer? As far as my understanding goes (but my knowledge of Web programming is extremely limited), to run LilyPond in a browser from the client side (i.e. the LilyPond compilation happens in the user's computer, not on the server), what you would need is to compile LilyPond (with all of its dependencies) to WASM with the Emscripten compiler. Cairo would just spare you building GhostScript for WASM in exchange for building Cairo and LibPNG for WASM. Jean

Le 24/08/2022 à 09:49, Andrew Bernard a écrit : Is Cairo related to producing PDF or only SVG? Both, but its advantages are the most shiny on SVG output, where it produces output enormously faster, and embeds fonts in the SVG file which ensures they can be viewed on any browser without getting fallback fonts. PDF output is also faster, but the difference is not very noticeable for normal use (although it is noticeable when compiling lots and lots and lots of snippets, like when compiling the LilyPond documentation), whereas SVG output in the current default SVG backend is really slow, and gets just as fast as PDF output with Cairo. The PDF Cairo backend currently doesn't support all features of the traditional PS backend (-dembed-source-code for example). Jean
