Help on changing staff sizes

[Till Rettig]

Hi,
I need some help about changing the distance of staff lines:

in NR 5.2.1 it says

"The context property fontSize and the layout property staff-space (in StaffSymbol) can be used to tune the size for individual staves. The sizes of individual staves are relative to the global size."

and

"Known issues and warnings: layout-set-staff-size does not change the distance between the staff lines."

If I click on the link to the StaffSymbol documentation, there is no staff-space property mentioned, well, it seems to be hidden in this y-extent, which is then explained by x-extent. But x-extent is missing. I would really much like to know the numbers that are used for the default so I can increase/decrease them accordingly.

Why is the lyout-set-staff-size by the way changing only font size, while global-layout-set-staff-size works correctly?

Greetings

Till
