3.1.105 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 4.25 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
(orX
), then this property determines whether the object is placedLEFT
,CENTER
orRIGHT
with respect to the other object. Otherwise, it determines whether the object is placedUP
,CENTER
orDOWN
. 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.length
(dimension, in staff space):
stem::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-begin-position
(number):
ly:stem::calc-stem-begin-position
User override for the begin position of a stem.
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): grob-interface, item-interface and stem-interface.
