Hi,
in the following markup I want draw-line to have the same Y-length as the brace.
\version "2.16.2"
factor = #0.175 % a rough estimation, and for default-staff-size only
size = #40
\markup {
\left-brace #size
\translate #`(0 . ,(/ (* size factor) -2))
\draw-line #`(0 . ,(* size factor))
}
The size of \left-brace is measured in pts according to it's
definition in /scm/define-markup-commands, "feta brace in point size",
and is absolute.
\draw-line uses staff-spaces, afaik.
I need the conversion factor for default and non-default-staff-size.
Well, there is
http://lilypond.org/doc/v2.17/Documentation/notation/distances-and-measurements
But I couldn't figure it out.
How to do it?
Regards,
Harm
