Hi Harm, Just catching up with email after being away myself…
The trouble is that centered-stencil moves the stencil so it is centered on the
X,Y point 0,0
from stencil.scm:
(define-public (centered-stencil stencil)
"Center stencil @var{stencil} in both the X and Y directions."
(ly:stencil-aligned-to (ly:stencil-aligned-to stencil X CENTER) Y CENTER))
But in my actual use case I need the first stencil to stay at its given
location, and then center the second stencil on it. (It is a note head
stencil, and I believe moving it to 0,0 will mess up the position of the stem,
etc.) So that’s the reason for the snippet. It could be made more explicit in
comments, description, example, etc. Let me know what you think.
