during my adventure with lilypond I came across a problem of invisible measures. I need to have some of bars in some staves quite transparent. To do so I moved the Staff_system_engraver form Staff context to Voice (in addition this manipulation causes barlines to disappear, but nevertheless...). Then I tried to make a bar (put in separate voice context) in one staff transparent by changing its "transparent" property, but it didn't work. But -- the same operation worked refering to "thickness" property. I don't know if my way of thinking is going in right way, but if someone has any idea, I would be greatful :)
And some code illustrating the problem:
\version "2.4.2"
%this doesn't seem to change anything
%staOFF = { \override Staff.StaffSymbol #'transparent = ##t }
%staON = { \revert Staff.StaffSymbol #'transparent }%this does its work.
staOFF = { \override StaffSymbol #'thickness = 2 }
staON = { \revert StaffSymbol #'thickess }vnTwo = \relative c' {
\context Voice ="Vn" { r1 | c4 r4 r2 }
\context Voice ="Vnt" { \staOFF s1 } \context Voice ="Vn" { | c4 }
}
vn = \relative c' {
r1
| c4 d e f |
}\layout {
\context {
\Staff
\remove "Staff_symbol_engraver"
}
\context {
\Voice
\consists "Staff_symbol_engraver"
}
}\score { <<
\context StaffGroup = "violiniI" <<
\context Staff ="vnI" \vn
\context Staff ="vnII" \vn
\context Staff ="vnIII" \vnWithGap
\context Staff ="vnIV" \vn
\context Staff ="vnV" \vn
>>
%here come other instrumental groups
>>
}
Sincerly yours, Andrew
PS. I'm working on linux Gentoo (x86), but this should be of no importance, shouldn't it?
