So here is an MWE showing the start of what I want to do - make
circular unfilled noteheads, and fitting in the staff size. This is
only a start, as the set of note styles I need have many extra
doodads, so this is just to get going.
It's been a long time since I have done any Lilypond Scheme. I'm
wanting help on how to size and position the noteheads properly. This
initial code is only my first sketch. I'm aware I need to flip the
side when the stem points down - that's not the main focus. I am also
foggy on the last arguments specfying the x and y extents. I can't
recall what extents are and how they affect this context (having
trouble searching for extent in the NR).
Extents are also called 'dimensions'. The extents of a grob
don't affect it itself, but they affect how other grobs react
to it, for example how a stem will attach to a note head, or
what space is reserved between two staves.
Stencils also have extents. They are used whenever stacking
stencils, aligning them, etc.
If the X-extent and Y-extent are not set to something particular,
the default to compute a grob's extents is to get them from
the stencil.
I don't think you'll find much about this topic in the
official documentation, but there is a bit of info here:
https://extending-lilypond.readthedocs.io/en/latest/backend.html#coordinates-extents-and-reference-points
The code is my own using the Bezier approximation for a circle. The
variable k is kappa - as referenced in a previous post on 'Circles'
and r is radius.
LilyPond supports exact circles, as you have found out in the
PostScript code in the other thread. Use make-circle-stencil to
create a circle. By the way, if you don't want to learn about
stencil functions, you could also use a markup:
(grob-interpret-markup grob #{ \markup \draw-circle ... #})
Here's a commented snippet that should help you get started:
\version "2.23.11"
\layout {
\context {
\Score
% custom circular noteheads
\override NoteHead.stencil =
#(lambda (grob)
(let* (;; The thickness of lines in the staff symbol; depends
;; on font size.
(staff-thickness (ly:staff-symbol-line-thickness grob))
;; Our own thickness -- scale it by the staff symbol's
;; thickness.
(thickness (* staff-thickness (ly:grob-property grob
'thickness)))
;; Our radius, measured to the center of the line.
(radius (- (* 1/2 (ly:staff-symbol-staff-space grob)) ;
half space
(* 1/2 thickness) ; account for our thickness
(* 1/2 staff-thickness) ; account for staff
line thickness
))
;; Draw the circle.
(circle (make-circle-stencil radius thickness #f)))
;; LilyPond expects a note head to tell how it should mesh with
;; other with its X extent. The part of the X extent before 0
;; is the “breapth” value. In our case, use 1/2*thickness
for the
;; breapth so that a reversed note head (not on the normal
size of
;; the stem due to seconds in chords) has the center of its
;; circle line on the stem.

Re: Help with custom noteheads
Hello Andrew,
is there any reason for using a custom circle approximation instead of simply
using (make-circle-stencil r th #f)?
The reason why your note heads are off is that a path stencil does not have an
extent. A path cotains arbitrary drawing commands, which means that Lilypond
does not really know how large the result would be. As such your Note Heads
are handled as points, but then draw outside of this, which means that
Lilypond cannot handle spacing properly.
What you need to do is to give the stencil an actual extent by using

extents are and how they affect this context (having trouble searching

The code is my own using the Bezier approximation for a circle. The

Re: Custom noteheads stem alignment
Hi Andrew, 2015-04-13 2:05 GMT+02:00 Andrew Bernard andrew.bern...@gmail.com: Dear Pierre, Thank you so very very much for this. You have solved two problems in one - the stem attachment and the elliptical counter, and it looks excellent. I can’t find words to express my appreciation for your help to me and the list in general. It’s most appreciated. You're welcome, I'm glad you like it ! :) Of course, when you help somebody, there’s always one more thing, isn’t there? I can’t resize the noteheads with \override NoteHead.font-size = #n What is going on there? 2015-04-13 2:36 GMT+02:00 Andrew Bernard : Now I understand - font size changes won’t affect this code as it is not drawing from the font. But I am not sure what code will scale the noteheads. Do I need a separate stencil for different sizes? That’s not so bad, as I only want to differentiate normal notes and grace notes. Yes, I think you'll have to scale note heads for graces' (e.g. \scale #'(.8 . .8) \sOne) Does it help?

Re: Custom noteheads stem alignment
Hi Paul,
Thanks for the reminder! Makes me think that I could simplified lots of my
path's codes ;).
Anyway...
I suppose that for 'make-path-stencil', 'Z' stays for 'closepath', doesn't
it? So what's 'z' for ?
Cheers,
Pierre

For another example of how to scale such custom stencils, especially with
the font size, but also to create a smaller grace note version, see:
http://lsr.di.unimi.it/LSR/Item?id=623
Especially this part:
scaleCustomClefStencilTwo =
#(lambda (grob)
(let* ((sz (ly:grob-property grob 'font-size 0.0))
(mult (magstep sz)))
(set! (ly:grob-property grob 'stencil)
(ly:stencil-scale
customClefStencilTwo
mult mult
This snippet shows a different way to make a path stencil with:
#(ly:make-stencil `(path
this is a low level way and it requires you to specify the X and Y extents
of the stencil.
See a higher level method here:
Using make-connected-path-stencil to draw custom shapes
http://lsr.di.unimi.it/LSR/Item?id=891
Which calculates the X and Y extents for you, but the path has to be
connected.
In 2.19 there is an improved version make-path-stencil where the path
doesn't need to be connected. There's not a snippet for it yet because it's
not in 2.18. As far as I know this method provides the most flexibility
and
least constraints. Here are some examples (the use of \markup here is just
for convenient demonstration):
%
\version 2.19
{
c'1^\markup \stencil
#(make-path-stencil
;; path, accepts both rmoveto and m, curveto and C, etc.
'(rmoveto -1 1
rcurveto 0 0.75 1 0.75 1 0
rcurveto 0 -0.75 -1 -0.75 -1 0
rcurveto -1 0 -1 1.5 -0.5 1.5
rmoveto 0.5 -1.5
c -1 0 -1 -1.5 -0.5 -1.5
m 1.5 1.5
c 2.5 0 2.5 4 4 4
m -4 -4
c 2.5 0 2.5 -4 4 -4)
;; line thickness
0.2

1 1
;; filled?
#f)
c'1^\markup \stencil
#(make-path-stencil
`(rmoveto 0 0
rlineto 2 0
rlineto 0 -2
rlineto -2 0
closepath
rmoveto 1.1 -1.1

rlineto -2 0
closepath
rmoveto 1.1 -1.1
rlineto 2 0
rlineto 0 -2

closepath)
0.2 1 1 #f)
c'1^\markup \stencil
#(make-path-stencil
'(moveto 6 0
curveto 0 -2 0 7 6 5
curveto 3 5 3 0 6 0)
0.2 0.5 0.5 #f)
c'1^\markup \stencil
#(make-path-stencil `(L 0 0 L 1 2 L 2 0 Z M 1 3 L 1 0) 0.2 1 1 #f)
c'1^\markup \stencil
#(make-path-stencil `(l 1 2 L 2 0 z) 0.2 1 2 #t)
}
%%%
And then there's the \path markup command method that Pierre used. This
one
requires that you have access to a grob so you can do grob-interpret-markup
(which is not required by the other methods).
I think that covers it!

Re: Custom noteheads stem alignment
Schneidy wrote Thanks for the reminder! Makes me think that I could simplified lots of my path's codes ;). Sure thing! When make-path-stencil arrives in the stable version things will be much simpler, as I can't think of a reason to use any of the other methods instead of it. It doesn't require a grob (as with grob-interpret-markup), it doesn't require manually specifying the X and Y extents, and the path can be disconnected / discontinuous. (It might even be worth deprecating and removing make-connected-path-stencil at some point, maybe in 2.22, that way 2.20 would have both make-path-stencil and make-connected-path-stencil for an easy transition for anyone using these.) Schneidy wrote Anyway... I suppose that for 'make-path-stencil', 'Z' stays for 'closepath', doesn't it? So what's 'z' for ? z and Z are both equivalent to closepath. This follows the SVG convention where both z and Z are included. Just for completeness sake, make-path-stencil works with either kind of commands, the more verbose or the single letters: moveto, rmoveto, lineto, rlineto, curveto, rcurveto, closepath M, m, L, l, C, c, Z, z Cheers, -Paul -- View this message in context: http://lilypond.1069038.n5.nabble.com/Custom-noteheads-stem-alignment-tp174412p174474.html Sent from the User mailing list archive at Nabble.com. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
Re: Custom noteheads stem alignment
In typography, the hole in characters such as ‘o’ and ‘a’ is called the counter. Most notes are engraved with an ellipse as the empty space, with ‘italic pen’ style thick and thin. The standard lilypond noteheads do this. Andrew On 12 April 2015 at 23:35:58, Pierre Perol-Schneider (pierre.schneider.pa...@gmail.com) wrote: 1.

Re: Custom noteheads stem alignment
Ok, thanks for the explanation Andrew.
But I'm afraid you can't do that here since 'elipse' draws a single line
with a specific thickness. A note head with a counter would need at least
two lines/elipses, one filled 'inside' and the other filled 'outside' (but
I don't know how to do that).
So I'm afraid you'll have to go through a postscript - that you don't want
if I understood you well - or a 'path' drawing.
Here's a draft for a 'path' (counter has, of course, to be adapted to your
design):

In typography, the hole in characters such as ‘o’ and ‘a’ is called the
counter. Most notes are engraved with an ellipse as the empty space, with
‘italic pen’ style thick and thin.
The standard lilypond noteheads do this.

Actually I made it to write a workaround that does the job. Better late than never. ^^ I still have to prepare a presentable sample before I post the result here though. Yes, the .cc files are very hard to understand. But after you look at a bunch of them, it gets better You can see where the styles are actually used to get glyph names in scm/output-lib.scm. Well, instead of medling further with the installation files I wrote now a workaround function that actually ignores the 'style property of the grob completely and just checks on the drumnote-name, i.e. bassdrum and overrides the 'stencil property with the function from the other thread to create custom stencils which produce different results depending on the duration-log. I think that's actually more or less the same you had in mind below. Maybe, but this seems like too much of a hack to me. But it's possible, I suppose. But if I were going to do it in this fashion, I think I'd add a new style to the drumStyleTable and then try to write a new print function that checks the style, and if it's parallelogram, use the parallelogram print routine, otherwise, use the regular notehead print routine. Now that I think about it, this approach is a promising way to do this without needing to add any font glyphs (which I think would be needed to define a new style). You already have a template for how to do this in your parallelogram function that Neil wrote. It checks the grob, and if its duration is 2, it writes the parallelogram. Otherwise, it calls the regular notehead stuff. But I think the output will likely be better if you define new glyphs in the font and define a new style. Eventually it'd definitely be easier to use and I think with some more tinkering I might even be able to do it but right now it works like I want it to and I prefer not to play with the installation files.

custom drumstyle-tables with custom noteheads?
Hi All, some time ago Neil Puttock helped me out to create a function that returns different notehead-stencils depending on the duration-log. http://www.mail-archive.com/lilypond-user@gnu.org/msg42720.html Now I was wondering if this procedure could be somehow integrated in a custom drumstyle-table but just using the functions-name in the style-field won't work, e.g. (snare parallelogram #5 0). Then I tried to figure out more about the standard settings which can be used here, i.e. cross, diamond, xcircle, slash, etc. but everything I found out by means of \displayMusic and (display)-scheme internally resulted that all those definitions are lists if am not mistaken ( 'cross or (quote cross) is list, isn't it?). Well, after this way turned to be a dead end I tried to search all files of the installation on more information on these defintions but didn't find any. Not even somewhere in the source I could find those. I don't know what else I can do to find out how this works internally on my own and if what I want to do is actually possible, so any help here is greatly appreciated. Regards, Tao -- Pt!

Have you tried using 'parallelogram instead of parallelogram? When
parallelogram is defined as a music function, every time scheme sees
parallelogram it tries to execute it. On the other hand, when it sees
'parallelogram is just puts the symbol (function name) rather than
evaluating it.

isn't it?).
'cross is a scheme symbol, not a list. And (quote cross) is just another
way to describe that symbol; 'cross is the same thing as (quote cross).
I hope you found that the drum style table is in the file
ly/drum-pitch-init.ly. The definitions is ly/drum-pitch-init.ly are a
little bit confusing, because they're all quoted lists. That means there's
a '( at the beginning of the list, so by default, nothing in the list is
evaluated and you don't need to put a ' before the symbol names. That's
also why the (ly:make-pitch ) calls in midiDrumPitches have a , before them;
the , means evaluate the following thing, even though it's in a quoted
list.
The other thing that is going to give you a little bit of grief is that the
drum-style tables are hashes, not alists. In the init file, they're set up
as alists, then converted to hashes by the map function at the end of the
init file, which calls alist-hash-table (defined in scm/lily-library.scm.
If you want to change a single entry, you'll have to do it with a call to
hashq-set!. You can see how it's used in scm/lily-library.scm. k-v means
key-value pair. So if you have a list you want to store like ('snare
'parallelogram #5 0), you'd do something like:
(hashq-set! name-of-drum-table-goes-here 'snare '(parallelogram 5 0))
with name-of-drum-table-goes-here replaced with the scheme name of the drum

No. I haven't considered it because the other to-use symbols don't have the

But since I am creating new drumStyleTables anyway I don't need to change a

As long as you're going to create a whole new drumStyleTable you don't need

Let me just address what is going in on with drum style. 'cross, 'diamond,
etc. are 'styles for the note-head-interface of the noteHead object that
will be created by the Drum_notes_engraver. They are interpreted by the
ly:note-head::print routine. The ly:note-head::print routine is a C++
routine found in lily/note-head.cc.
Basically, the routine looks for a given note head style, and uses that to
print the notes. You can see the note head styles in appendix B.7 of the
Notation Reference.
Since the drumStyleTable uses note styles to set the note heads, if you want
to create your own drumStyleTable, I think you'll need to add a new notehead
style. And I have no idea how to do that.
Again, I'm sorry for my misleading earlier reply. I thought I knew what was
going on, but I was wrong. I hope this new answer helps.
Thanks,
Carl

Re: custom noteheads
hi all, well, so far I tried myself to find a solution for this and came to the point where scheme is the only way to do this. My scheme is very limited, especially the connection to the ly:functions is something I don't really get yet. I simply don't know how to apply these functions I guess, or maybe when to use which function. Generally I thought I could define a music-function that overrides the stencil of a NoteHead depending on the car of ly:make-duration. So if it's =1 it'll place a custom stencil for half and whole notes and if it's =2 for filled notes. I hope that makes sense. I just don't know how to do this in lily.

If you're overriding the NoteHead stencil, you can access the property 'duration-log, which will tell you the duration of the current note. Then you can use case to set the stencil conditionally: parallelogram = #(lambda (grob) ; get duration log of NoteHead object (let* ((dur (ly:grob-property grob 'duration-log))) (case dur ; if dur = minim, return parallelogram stencil ((2) (ly:make-stencil (list 'embedded-ps gsave currentpoint translate newpath 0 0.25 moveto 1.3125 0.75 lineto 1.3125 -0.25 lineto 0 -0.75 lineto closepath fill grestore ) (cons 0 1.3125) (cons 0 0))) ; otherwise, set to default print function (else (ly:note-head::print grob) Regards, Neil -- Sensationsangebot nur bis 30.11: GMX FreeDSL - Telefonanschluss + DSL für nur 16,37 Euro/mtl.!* http://dsl.gmx.de/?ac=OM.AD.PD003K11308T4569a ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
custom noteheads
hi list, I came across ths snippet from the lsr: http://lsr.dsi.unimi.it/LSR/Item?id=516 Now I was thinking if it is possible to assign such custom heads to different duratiosn, e.g. that half notes look different than quarter and eigths, etc. Also if it is possible to use them in a custom drum table but I think I can find this out easily, just if someone already knows. regards, Tao -- Pt!

Re: Custom noteheads and chords
The example in section 4.6.5 of the Learning Manual might be a good starting point.

Custom noteheads and chords
Hello,
With the help of a recent thread I have custom noteheads working just
the way I want them except for one detail. I would like to have chords
where each note in the chord has a different custom notehead. Here's
an example.
This works and each note has its own custom notehead.
{
\noteheadOne c
\noteheadTwo d
}
This is a syntax error:
{
\noteheadOne c \noteheadTwo d 2
}
This is not a syntax error but each note has noteheadTwo
{
\noteheadOne c2 \noteheadTwo e2
}
Thanks for the help.
-Eric

\tweak may be the command you need. Have a look at section 4.1.4 Tweaking
methods in the Learning Manual for release 2.11 to see why this is needed
and how to use it. The explanation there applies just as well to release
2.10. However, I believe it is not possible to use \tweak in a variable, so
this might not be quite the answer you want.

Re: Custom Noteheads
I'm afraid you have to dig into the source code yourself. Such a project would involve several steps: designing the font symbols for the noteheads or finding an existing font that contains the symbols, writing a replacement or complement to Note_head::print (in C++ or Scheme) and the corresponding output functions in scm/output-*.scm, among others. /Mats Aaron Dalton wrote: I've done a little searching in the archives but I can't seem to find any specific information.
