Score testing

Unreadable Score extension output in dark mode

Hopefully I can get the Score extension working to produce SVG output, instead of the transparent PNG image that needs a white background styling for dark mode otherwise it's unreadable.

Examples

Range of the contrabass trombone, as used on Wikipedia:

${ \new Staff \with { \remove "Time_signature_engraver" } \clef bass \key c \major \cadenzaOn \ottava #-1 \tweak font-size #-2 fis,,,1 \finger \markup \text "poss." \ottava #0 c,,1 \glissando d'1 \tweak font-size #-2 f'1 }$

The Spear motif from Das Rheingold:

$\layout { ragged-right = ##t \context { \Score \omit BarNumber } } \relative g { \override DynamicTextSpanner.style = #'none \override Hairpin.minimum-length = #5 \clef bass \key c \major g2~ \ff g8 f8 e8. d16 c4 b a g f e d c \break b a g f e1~ \dim\! << e1~ { s2 s4 s4 \> } >> e4 \! \p r4 r2 }$

The Summit from Ein Alpensinfonie, which may or may not be a contrabass trombone excerpt:

$\relative c, { \time 4/4 \clef bass \key c \major r2 r4\ff g\tenuto c2.\tenuto c4\tenuto g'2.\tenuto g4\tenuto c1 e2~ e4.. b16 a1 g1 c8 r8 r4 r2 \bar "|." }$
