Stem

Stem objects are created by: Stem_engraver

Standard settings:

direction (direction):

ly:stem::calc-direction

If side-position is 1 (#X), then this property determines if the object is placed #LEFT, #CENTER or #RIGHT with respect to the other object. Otherwise, it determines if the object is placed #UP #CENTER or #DOWN. Numerical values may also be used. #UP=1, #DOWN=-1, #LEFT=-1, #RIGHT=1, CENTER=0 but also other numerical values are permitted.

duration-log (integer):

stem::calc-duration-log

The 2-log of the note head duration, i.e. 0=whole note, 1 = half note, etc.

default-direction (direction):

ly:stem::calc-default-direction

Direction determined by note head positions.

stem-end-position (number):

ly:stem::calc-stem-end-position

Where does the stem end (the end is opposite to the support-head.

neutral-direction (direction):

-1

Which direction to take in the center of the staff.

stencil (unknown):

ly:stem::print

The symbol to print.

X-extent (pair of numbers):

ly:stem::width

Hard coded extent in X direction.

Y-extent (pair of numbers):

ly:stem::height

See X-extent.

length (dimension, in staff space):

ly:stem::calc-length

User override for the stem length of unbeamed stems.

thickness (number):

1.3

Line thickness, generally measured in line-thickness.

X-offset (number):

ly:stem::offset-callback

The horizontal amount that this object is moved relative to its X-parent

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 interfaces: stem-interface, item-interface, font-interface and grob-interface
