### 3.2.72 note-spacing-interface

This object calculates spacing wishes for individual voices.

#### User settable properties:

> `knee-spacing-correction` (number)

>   Factor for the optical correction amount for kneed beams. Set between `0` for no correction and `1` for full correction.

> `same-direction-correction` (number)

>   Optical correction amount for stems that are placed in tight configurations. This amount is used for stems with the same direction to compensate for note head to stem distance.

> `stem-spacing-correction` (number)

>   Optical correction amount for stems that are placed in tight configurations. For opposite directions, this amount is the correction for two normal sized stems that overlap completely.

> `space-to-barline` (boolean)

>   If set, the distance between a note and the following non-musical column will be measured to the bar line instead of to the beginning of the non-musical column. If there is a clef change followed by a bar line, for example, this means that we will try to space the non-musical column as though the clef is not there.

>   DOCME
