3.1.98 Stem
Stem objects are created by: Stem_engraver.
Standard settings:
direction(direction):
ly:stem::calc-directionIf
side-axisis0(or#X), then this property determines whether the object is placed#LEFT,#CENTERor#RIGHTwith respect to the other object. Otherwise, it determines whether the object is placed#UP,#CENTERor#DOWN. Numerical values may also be used:#UP=1,#DOWN=-1,#LEFT=-1,#RIGHT=1,#CENTER=0.duration-log(integer):
stem::calc-duration-logThe 2-log of the note head duration, i.e.,
0= whole note,1= half note, etc.default-direction(direction):
ly:stem::calc-default-directionDirection determined by note head positions.
stem-end-position(number):
ly:stem::calc-stem-end-positionWhere does the stem end (the end is opposite to the support-head)?
neutral-direction(direction):
-1Which direction to take in the center of the staff.
stencil(unknown):
ly:stem::printThe symbol to print.
X-extent(pair of numbers):
ly:stem::widthHard coded extent in X direction.
Y-extent(pair of numbers):
ly:stem::heightHard coded extent in Y direction.
length(dimension, in staff space):
ly:stem::calc-lengthUser override for the stem length of unbeamed stems.
thickness(number):
1.3Line thickness, generally measured in
line-thickness.flag(unknown):
ly:stem::calc-flagA 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-styleproperty to determine the correct glyph for the flag. By providing your own function, you can create arbitrary flags.X-offset(number):
ly:stem::offset-callbackThe horizontal amount that this object is moved relative to its X-parent.
Y-offset(number):
ly:staff-symbol-referencer::callbackThe vertical amount that this object is moved relative to its Y-parent.
This object supports the following interface(s): stem-interface, item-interface, font-interface and grob-interface.
