Instrument names and smallest possible bounding box
1) Instrument names.
The default placement of instrument names seems a bit messy compared to my
default Sibelius output:
Lilypond:
They seem "off", not alligned properly. This is of course the fault of the
author. Most likely there is a easy fix. Suggestions?
2) I need to export pngs for my latex documents and i would like the bounding
box to be as small as possible. How do i do this?

They seem "off", not alligned properly. This is of course the fault of

Well, it’s not your fault: the instrument names are center-aligned by
default. To right-align them, use
\layout {
\context {
\StaffGroup % or Staff, or GrandStaff, or ChoirStaff…
\override InstrumentName.self-alignment-X = 1
}
}

LilyPond tries to center-align the instrument names. Long names which
don’t fit into the margin defined by indent (default 1.5cm (?)) are
right-aligned (“Woodwind” in your example). This “mixing” behaviour
looks odd, I agree. You can make the indent bigger so all names are
center-aligned or change the alignment of instrument names globally;
here are both solutions (they also can be combined):
\version "2.19.35"
\paper {
%indent = 1.8\cm % short center-aligned (in this margin), long right
%indent = 3.5\cm % both center-aligned
}
%{
\layout {
\context {
\Staff
\override InstrumentName.self-alignment-X = #RIGHT
}
}
%}
<<
\new Staff \with {
instrumentName = "very long name"
} { R1 \break R1 }
\new Staff \with {
instrumentName = "short"
} { R1 \break R1 }

There is a lilypond option -dpreview which does this iirc. And apart
from that: Do you know lilypond-book?

I don't know how well this fits into your workflow, but I'd be inclined to trim the images after export using pnmcrop, automated by a Makefile recipe. Probably simpler than trying to get Lilypond to resize its "page" to fit the material. If you were exporting in a vector format, the trimming operation might be harder, but trimming off white borders on a PNG file is easy. -- Matthew Skala msk...@ansuz.sooke.bc.ca People before principles. http://ansuz.sooke.bc.ca/ ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Hi Carl-Henrik > 1) Instrument names. > The default placement of instrument names seems a bit messy compared to my > default Sibelius output: Actually, I much prefer the Lilypond output — it almost perfectly matches the convention of hand-engraved music. > They seem "off", not alligned properly. Do you want them right-aligned? If so, that’s dead simple: \override InstrumentName.self-alignment-X = #RIGHT Hope this helps! Kieren.

You can also use David N’s great custom-align function — see snippet, below.
Hope this helps!
Kieren.
p.s. David N: Is this code ready to present as a patch? I think it’s not only a
very useful function, it should be Lilypond’s default setting.

The code also is badly in need of some caching to avoid repetition of expensive calculations. Not sure of the best way to do this. So no patch yet...
