The documentation at
http://lilypond.org/doc/v2.19/Documentation/notation/setting-the-staff-size
makes it sound like set-global-staff-size and layout-set-staff-size
only
differ in their scope (the former affects the whole book, and the
latter
only the score pertaining to a particular layout). Attached is a Tiny
Example using set-global-staff-size. Reproduction steps:
1. Compile the example to "global.pdf".
2. Move the comment from line 4 to line 2
3. Compile the modified example to "layout.pdf"
If the documentation is correct, I would expect set-global-staff-size
and
layout-set-staff-size to work the same when there is only one staff.
Comparing the resulting global.pdf and layout.pdf shows that this is
not
the case.
I have a book with two \scores in it, and would like one to have a
larger
set-global-staff-size than the other. I'll continue experimenting and
see
if I can get what I want, but I thought I would drop a note about
this.
