Hi Alexander,
is it possible to tell LilyPond to use the same vertical positions for all topmost and
bottommost staff lines of different pages? Rephrased, can I say "I know what I'm
doing, ignore all vertical extents below the last staff lines of a page for vertical
stretching, even if it collides with the footer"?
Did you try setting #'bottom-system-spacing #'padding to 0 and using
#'minimum-distance only?
According to [my reading of] the docs, this should work.
Hi, Kieren,
it's the right track, thanks a lot.
\paper { bottom-system-spacing = #'((minimum-distance . 2) (padding .
-10)) }
is the candidate. Looks like I have to set #'padding to a negative value
to tell LilyPond to ignore vertical extents up to this value below the
last staff line; -inf.0 is, while technicially the best guess, not quite
useful, since any footer will print into the staff lines then (and this
can't be helped with \vspace, e.g.). A finite negative value is okay;
the collision with the footer can then be dealt with using \vspace and
an appropriate (read: trial-and-error) offset.
It's a pity, though, that bottom-system-spacing relates to the top of
the bottom margin instead of the top of the footer + foot-separation...
That'd both allow -inf.0 for padding, and make finding the correct
\vspace value in the footer far easier. (For some reason, the latter is
not quite what I'd expect, e.g. for padding = -100 I need \vspace #31.5
to get a nice result for a two-line footer?!)
Cheers,
Alexander
