'm trying to reduce the line width in a custom header template,
having several lines combined in \center-column. I tried using
the \vspace command, which seems the only thing in the docs
slightly related to line height, but it doesn't seem to handle
negative numbers.
bookTitleMarkup = \markup
{
\fill-line
{ \center-column
{ \fontsize #4.5 \fromproperty #'header:title
\fontsize #-3 \fromproperty #'header:copyMusic
\vspace #-2
\fontsize #-3 \fromproperty #'header:copyLyric
} } }
Any way to set the line height to a smaller number than the
default value in \center-column?
