Re: Get current staff size

[Kevin Barry]

Hi All,

Thank you for your suggestions. I did try using the StaffSymbol's
staff-height, but that seems to be in staff spaces (with a little
added on for the staff lines), so it's always just a little above 4.

Timothy's suggestions works (I never would have found ly:pt).

As it happens, I found another solution similar to Valentin's using
the output-scale property, which works if there are different values
for staff-size globally and in the local layout.

Thanks all!

Kevin
