3.1.131 StemTremolo

A stem tremolo.

StemTremolo objects are created by the following engraver(s): Stem_engraver.

Standard settings:

beam-thickness (dimension, in staff space):

0.48

Beam thickness, measured in staff-space units.

beam-width (dimension, in staff space):

ly:stem-tremolo::calc-width

Width of the tremolo sign.

direction (direction):

ly:stem-tremolo::calc-direction

If side-axis is 0 (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.

parent-alignment-X (number):

0

Specify on which point of the parent the object is aligned. The value -1 means aligned on parent’s left edge, 0 on center, and 1 right edge, in X direction. Other numerical values may also be specified - the unit is half the parent’s width. If not a number, align on the parent’s reference point. If unset, the value from self-alignment-X property will be used.

shape (symbol):

ly:stem-tremolo::calc-shape

This setting determines what shape a grob has. Valid choices depend on the stencil callback reading this property.

slope (number):

ly:stem-tremolo::calc-slope

The slope of this object.

stencil (stencil):

ly:stem-tremolo::print

The symbol to print.

X-extent (pair of numbers):

ly:stem-tremolo::width

Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

X-offset (number):

ly:self-alignment-interface::aligned-on-x-parent

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

Note that many objects have special positioning considerations, which cause any setting of X-offset to be ignored or modified, even though the object supports the self-alignment-interface.

Y-extent (pair of numbers):

#<unpure-pure-container #<procedure ly:grob::stencil-height (_)> #<procedure ly:stem-tremolo::pure-height (_ _ _)> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

Y-offset (number):

#<unpure-pure-container #<procedure ly:stem-tremolo::calc-y-offset (_)> #<procedure ly:stem-tremolo::pure-calc-y-offset (_ _ _)> >

The vertical amount that this object is moved relative to its Y-parent.

Note that many objects have special positioning considerations, which cause any setting of Y-offset to be ignored or modified, even though the object supports the self-alignment-interface.

This object supports the following interface(s): grob-interface, item-interface, self-alignment-interface and stem-tremolo-interface.

This object is of class Item (characterized by item-interface).
