Re: Custom note heads

2017-12-16 Thread Andrew Bernard
Hi Helge,

What sort of shapes do you want? Can you supply an illustration? [A MGE -
minimal graphic example!]

You can use graphic files, or you can write Scheme to generate custom
postscript paths. The latter can be very complex, but is of course very
powerful. or you can use path construction commands for the stencil of the
notehead.

There are quite a few examples on LSR of how to make different shape
noteheads. You may find id 891 to be the simplest, avoiding postscript
(which has some disadvantages in relation to SVG output if you need that).

Custom note heads

2017-12-16 Thread Helge Kruse
Hello,

I've been asked to write some scores with custom note heads. These heads
are designed for beginners. I know that the Emmentaler font contains
some special heads but I don't know how to add new shapes.

I found this question at Stackoverflow
https://stackoverflow.com/questions/47341754/lilypond-custom-global-note-heads.
But this doesn't work, even if I add a file g.eps I get the error

Preprocessing graphical objects...C:/Program Files
(x86)/LilyPond-2.19-65/usr/share/lilypond/current/scm/stencil.scm:987:26:
In procedure list-ref in expression (list-ref bbox 2):
C:/Program Files
(x86)/LilyPond-2.19-65/usr/share/lilypond/current/scm/stencil.scm:987:26:
Wrong type argument in position 1: #f

How can I define my own custom note heads? I don't prefer EPS in this
field, can be any graphic file other format.

Or these other way round: At
http://lilypond.org/doc/v2.18/Documentation/notation/note-heads is a
Ez_numbers_engraver. Can this be modified to do the work?

Best regards
Helge
