3.1.99 Stem
Stem objects are created by: Stem_engraver.
Standard settings:
beamlet-default-length
(pair):
'(1.1 . 1.1)
A pair of numbers. The first number specifies the default length of a beamlet that sticks out of the left hand side of this stem; the second number specifies the default length of the beamlet to the right. The actual length of a beamlet is determined by taking either the default length or the length specified by
beamlet-max-length-proportion
, whichever is smaller.beamlet-max-length-proportion
(pair):
'(0.75 . 0.75)
The maximum length of a beamlet, as a proportion of the distance between two adjacent stems.
default-direction
(direction):
ly:stem::calc-default-direction
Direction determined by note head positions.
details
(list):
'((lengths 3.5 3.5 3.5 4.5 5.0 6.0) (beamed-lengths 3.26 3.5 3.6) (beamed-minimum-free-lengths 1.83 1.5 1.25) (beamed-extreme-minimum-free-lengths 2.0 1.25) (stem-shorten 1.0 0.5))
Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a
details
property.direction
(direction):
ly:stem::calc-direction
If
side-axis
is0
(or#X
), then this property determines whether the object is placed#LEFT
,#CENTER
or#RIGHT
with respect to the other object. Otherwise, it determines whether the object is placed#UP
,#CENTER
or#DOWN
. Numerical values may also be used:#UP
=1
,#DOWN
=-1
,#LEFT
=-1
,#RIGHT
=1
,#CENTER
=0
.duration-log
(integer):
stem::calc-duration-log
The 2-log of the note head duration, i.e.,
0
= whole note,1
= half note, etc.flag
(stencil):
ly:stem::calc-flag
A function returning the full flag stencil for the
Stem
, which is passed to the function as the only argument. The default ly:stem::calc-stencil function uses theflag-style
property to determine the correct glyph for the flag. By providing your own function, you can create arbitrary flags.length
(dimension, in staff space):
ly:stem::calc-length
User override for the stem length of unbeamed stems.
neutral-direction
(direction):
-1
Which direction to take in the center of the staff.
stem-end-position
(number):
ly:stem::calc-stem-end-position
Where does the stem end (the end is opposite to the support-head)?
stencil
(stencil):
ly:stem::print
The symbol to print.
thickness
(number):
1.3
Line thickness, generally measured in
line-thickness
.X-extent
(pair of numbers):
ly:stem::width
Hard coded extent in X direction.
X-offset
(number):
ly:stem::offset-callback
The horizontal amount that this object is moved relative to its X-parent.
Y-extent
(pair of numbers):
ly:stem::height
Hard coded extent in Y direction.
Y-offset
(number):
ly:staff-symbol-referencer::callback
The vertical amount that this object is moved relative to its Y-parent.
This object supports the following interface(s): font-interface, grob-interface, item-interface and stem-interface.
