I definitely could, but, like I said, the rotation part isn't what I
can't do. I need to be able to know _when_ they are needed and when
they aren't. I can't figure out how to do that. Good thought, though.
As said I'm not really into this. But my reasoning was that when
creating independent noteheads for stem up/down in the font you could
make the decision "manually" and don't have to find a way to let
LilyPond find it out for you.

Just a very uneducated guess: couldn't you make rotated copies in
the font itself?

I've been collaborating with an Italian design student that
created numerous music fonts for a school project, but they
aren't actually used in any notation program (yet), but he has
agreed to work with me and take the steps necessary to make
them usable with LilyPond. Each of his fonts are quite
stylized and are designed to represent a different genre of
music. The one I'm doing first is meant to imitate the feeling
of the famous Didot (or Bodoni) text font, with lots of thick
and thin elements. Anyone seen this before? It is his designer
that they be made available for free, licensed under the OFL.
He's pretty excited to see his work get out there.
Before I can do this, however, there's one issue I haven't
been able to solve. The noteheads (quarter and half) are
designed such that it really only has ONE stem attachment
point (marked in orange in the attached image).
For stems going up (right-side of image), it is the top-right
point. For stems going down (left-side of image), the glyph
must be rotated 180 degrees so the same attachment point is
now at the bottom-left where the stem is located. The rotation
part I've been able to figure out, but it isn't automatic yet.
My question is this: how do I determine when a particular
notehead's _true_ stem attachment at that moment is going to
be at the bottom-left so I can rotate the notehead glyph? I
don't care what the value is, though it may be needed to
determine the event, I just want to know _when_ it happens. I
hope that makes sense.
Here's my simple code so far:
#(define alt-notehead
(lambda (grob)
(let* ((stil (ly:note-head::print grob))
(newstil (ly:stencil-rotate stil 180 0 0)))
newstil)))
Then, when I want to use it, I do:
(\once) \override NoteHead.stencil = #alt-notehead
When I get the 'stem-attachment property of the notehead, it
always gives me the top-right value, regardless of where the
stem is actually attached. I'm hoping this will work for
chords, too, though I haven't experimented enough to know for
sure. Any help is always appreciated!
Regards,
Abraham
