Re: scheme problem: colored background, layers

Hi everybody, now I could finish two scores that have been waiting for that colored background trick. Maybe they are somewhat extreme examples... If anyone is interested: http://jkg-musik.jimdo.com/lilypond For the colored arrows from the second example, I've created a snippet as well: http://lsr.di.unimi.it/LSR/Item?u=1id=961 Cheers, Klaus ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Re: scheme problem: colored background, layers
Hi Pierre,
thanks for taking the time to think about it.
Meanwhile, after some sleepless nights ;-) I've found another way to
get some results:
% ---
\version 2.18.0
colorSpan =
#(define-music-function (parser location y-lower y-upper color) (number?
number? color?)
#{
\override Staff.HorizontalBracket #'stencil =
$(lambda (grob)
(let* (
(area (ly:horizontal-bracket::print grob))
(X-ext (ly:stencil-extent area X))
(Y-ext (ly:stencil-extent area Y))
)
(set! Y-ext (cons y-lower y-upper)
)
(ly:grob-set-property! grob 'layer -10)
(ly:make-stencil (list 'color color
(ly:stencil-expr (ly:round-filled-box X-ext Y-ext 0))
X-ext Y-ext))
))
#})
{
{ R1
\colorSpan #-5 #5 #(rgb-color 1.0 0.9 0.5) c'2\startGroup g' c' \stopGroup
\colorSpan #0 #5 #(rgb-color 0.5 1.0 0.5)
r4\startGroup r \stopGroup
\colorSpan #-5 #0 #(rgb-color 0.9 1.0 0.5) r\startGroup r\stopGroup }
\\
{
\override Voice.ClusterSpanner.color = #(rgb-color 0.5 0.6 1)
\override Voice.ClusterSpanner.layer = #-1
\makeClusters { s1 c'2 g' c' s s1 }
}
}
\layout {
\context {
\Voice
\consists Horizontal_bracket_engraver
\override HorizontalBracket #'thickness = #0
\override HorizontalBracket #'bracket-flare = #'(0 . 0)
\override HorizontalBracket #'Y-extent = #'(0 . 0)
\override HorizontalBracket #'edge-height = #'(0 . 0)
\override HorizontalBracket #'Y-offset = #0
\override HorizontalBracket #'shorten-pair = #'(-1 . -0.75)
}
}
% ---
Result:
http://4.bp.blogspot.com/-THmAQWfqDaw/VHztoaE6N2I/ACs/9Sqgl4ViMBc/s1600/ly-ex3.gif
This time, I abused the Horizontal_bracket_engraver that is used for
\startGroup and \stopGroup and replaced it's stencil by a rectangle.
Because it's not attached to the StaffSymbol, it can be placed in a
different layer, so the blue cluster and the staff lines both stay visible.
Anyway, LilyPond does the horizontal spacing without the need for manual
work.
This might make life easier for doing crazy things like this:

thanks for your reply.
Unfortunately, changing the layer value from -10 to -2 doesn't
help. The problem is that the function places the staff lines and
the colored rectangle into the *same* layer, whereas I need to
leave the staff lines in layer 0 and put the rectangle into layer
-2 (or even less).
This would allow me to put other clusters *between* them like in
the first example.
Right ! Now I see the problem, 'seems that I've replied without
thinking...
I have already found another interesting snippet:
http://lsr.di.unimi.it/LSR/Item?id=953
But in that case, I would have to find the dimensions for the
rectangle by trial-and-error, whereas overriding the StaffSymbol
seems to be a very easy way...
Actually I've made this one (which is more or less a draft). I'll try
to see what I can do with it. No promise though :(

Pierre

Hi,

Here is my problem:
Now the staff lines and the yellow rectangle are located in the same
layer, so it's not possible to place the blue cluster between them.
Is there a way to make the scheme function put the staff lines
(StaffSymbol) and the yellow rectangle into different layers?
How about changing the layer value from -10 to -2 ?
bgColor =

number? string?)
#{
\stopStaff
\override Staff.StaffSymbol.stencil =
$(lambda (grob)
(let* ((staff (ly:staff-symbol::print grob))
(X-ext (ly:stencil-extent staff X))
(Y-ext (ly:stencil-extent staff Y)))
(set! Y-ext (cons
(- (car Y-ext) y-lower)
(+ (cdr Y-ext) y-upper)))
;; change layer's value to -2
(ly:grob-set-property! grob 'layer -2)
(ly:stencil-add
(ly:make-stencil (list 'color (eval-string color)
