LilyPond Internals Reference: 3.1.126 UnaCordaPedal

### 3.1.126 UnaCordaPedal

UnaCordaPedal objects are created by: Piano_pedal_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)`.

> `font-shape` (symbol):

>   `'italic`

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

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

>   `0.0`

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

> `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.

> `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.

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