LilyPond Internals Reference: 3.1.104 PianoPedalBracket

### 3.1.104 `PianoPedalBracket`

A piano pedal bracket. It can also be part of `SostenutoPedal`, `SustainPedal`, or `UnaCordaPedal` grobs if they are printed in a bracketed style.

`PianoPedalBracket` objects are created by: `Piano_pedal_engraver`.

Standard settings:

`bound-padding` (number):

  `1.0`

  The amount of padding to insert around spanner bounds.

`bracket-flare` (pair of numbers):

      '(0.5 . 0.5)

  A pair of numbers specifying how much edges of brackets should slant outward. Value `0.0` means straight edges.

`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`.

`edge-height` (pair):

      '(1.0 . 1.0)

  A pair of numbers specifying the heights of the vertical edges: `(left-height . right-height)`.

`shorten-pair` (pair of numbers):

      '(0.0 . 0.0)

  The lengths to shorten on both sides a hairpin or text-spanner such as a pedal bracket. Positive values shorten the hairpin or text-spanner, while negative values lengthen it.

`stencil` (stencil):

  `ly:piano-pedal-bracket::print`

  The symbol to print.

`style` (symbol):

  `'line`

  This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

`thickness` (number):

  `1.0`

  For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to `Staff.StaffSymbol.thickness`).

`vertical-skylines` (pair of skylines):

  `#<unpure-pure-container #<procedure ly:grob::vertical-skylines-from-stencil (_)> #<procedure ly:grob::pure-simple-vertical-skylines-from-extents (_ _ _)> >`

  Two skylines, one above and one below this grob.

This object supports the following interface(s): `grob-interface`, `line-interface`, `piano-pedal-bracket-interface`, `piano-pedal-interface` and `spanner-interface`.

This object is of class Spanner (characterized by `spanner-interface`).
