### 3.1.131 TupletNumber

TupletNumber objects are created by: Tuplet_engraver.

Standard settings:

> `avoid-slur` (symbol):

>   `'inside`

>   Method of handling slur collisions. Choices are `inside`, `outside`, `around`, and `ignore`. `inside` adjusts the slur if needed to keep the grob inside the slur. `outside` moves the grob vertically to the outside of the slur. `around` moves the grob vertically to the outside of the slur only if there is a collision. `ignore` does not move either. In grobs whose notational significance depends on vertical position (such as accidentals, clefs, etc.), `outside` and `around` behave like `ignore`.

> `direction` (direction):

>   `tuplet-number::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`.

> `font-shape` (symbol):

>   `'italic`

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

> `font-size` (number):

>   `-2`

>   The font size, compared to the ‘normal’ size. `0` is style-sheet’s normal size, `-1` is smaller, `+1` is bigger. Each step of 1 is approximately 12% larger; 6 steps are exactly a factor 2 larger. Fractional values are allowed.

> `stencil` (stencil):

>   `ly:tuplet-number::print`

>   The symbol to print.

> `text` (markup):

>   `tuplet-number::calc-denominator-text`

>   Text markup. See Formatting text.

> `X-offset` (number):

>   `ly:tuplet-number::calc-x-offset`

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

> `Y-offset` (number):

>   `ly:tuplet-number::calc-y-offset`

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

This object supports the following interface(s): font-interface, grob-interface, spanner-interface, text-interface and tuplet-number-interface.
