3.1.53 InstrumentSwitch

InstrumentSwitch objects are created by: Instrument_switch_engraver.

Standard settings:

direction (direction):

1

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.

extra-spacing-width (pair of numbers):

'(+inf.0 . -inf.0)

In the horizontal spacing problem, we pad each item by this amount (by adding the ‘car’ on the left side of the item and adding the ‘cdr’ on the right side of the item). In order to make a grob take up no horizontal space at all, set this to (+inf.0 . -inf.0).

outside-staff-priority (number):

500

If set, the grob is positioned outside the staff in such a way as to avoid all collisions. In case of a potential collision, the grob with the smaller outside-staff-priority is closer to the staff.

padding (dimension, in staff space):

0.5

Add this much extra space between objects that are next to each other.

self-alignment-X (number):

-1

Specify alignment of an object. The value -1 means left aligned, 0 centered, and 1 right-aligned in X direction. Other numerical values may also be specified.

side-axis (number):

1

If the value is X (or equivalently 0), the object is placed horizontally next to the other object. If the value is Y or 1, it is placed vertically.

staff-padding (dimension, in staff space):

0.5

Maintain this much space between reference points and the staff. Its effect is to align objects of differing sizes (like the dynamics p and f) on their baselines.

stencil (stencil):

ly:text-interface::print

The symbol to print.

X-offset (number):

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

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

Y-offset (number):

ly:side-position-interface::y-aligned-side

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, self-alignment-interface, side-position-interface and text-interface.
