Re: markup-command boxing the real printed ink?

[Valentin Petzel]

Hm, you’re right. But if you replace this by something directly drawn with 
PostScript commands, you’ll see that Lilypond does not have any idea about 
what’s there. So I guess Lilypond is able to handle stencil it knows very 
well.

And yes, Skylines are a concept of Lilypond, but Lilypond does not really 
„know” how the score looks. Lilypond thinks in objects that physically bounded 
by a skyline box. As you have shown, Lilypond is able to refine this into 
polygons for the standard symbols (for which we can quite easily find ways to 
get this actual information, as these things are eighter glyphs or lines).

But this still does not solve the Problem that Lilypond is not actually able 
to „see” where there is black stuff in an arbitrary stencil.

Cheers,
Valentin
