Hi.
I'd like to make my own stencils using PostScript
commands, but the documentation on this topic isn't
quite there yet, I guess. I don't understand how
the "string" passed to 'embedded-ps is supposed to
be formatted.
I'm using the ps backend, and the relevant lines in
/scm/output-ps.scm (lines 129-130) are pretty sparse:
(define (embedded-ps string)
string)
Here's my naive attempt, which is clearly wrong. No
error messages are generated, but no stencil appears.
My example here would be a square note-head, but it's
just an example. That is to say, I don't need work-
arounds or clever square note-head solutions; I just
want to understand how to make embedded-ps stencils.
Thanks!
Mark
