### 3.1.91 SostenutoPedal

SostenutoPedal objects are created by: Piano_pedal_engraver.

Standard settings:

> `stencil` (unknown):

>   `ly:text-interface::print`

>   The symbol to print.

> `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`.

> `X-offset` (number):

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

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

> `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)`.

> `padding` (dimension, in staff space):

>   `0.0`

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

> `font-shape` (symbol):

>   `'italic`

>   Select the shape of a font. Choices include `upright`, `italic`, `caps`.

> `self-alignment-X` (number):

>   `0`

>   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.

This object supports the following interface(s): text-interface, self-alignment-interface, piano-pedal-script-interface, item-interface, font-interface and grob-interface.
