class neoscore.western.slur.Slur[source]

Bases: Spanner2D, AbstractSlur

A slur, conventionally drawn between notes.

Note that this class currently provides no smart positioning logic to automatically attach to and span between Chordrests.

For ties, see Tie, which works identically to this class except that it always spans horizontally.

__init__(pos: PointDef, parent: PositionedObject, end_pos: PointDef, end_parent: Optional[PositionedObject] = None, direction: DirectionY = DirectionY.UP, height: Optional[Unit] = None, arch_length: Optional[Unit] = None, font: Optional[MusicFont] = None, brush: Optional[BrushDef] = None, pen: Optional[PenDef] = None)[source]
  • pos – The starting point.

  • parent – The parent for the starting position. If no font is provided, this parent or one of its ancestors must implement HasStaffUnit.

  • end_pos – The stopping point.

  • end_parent – The parent for the ending position. If None, defaults to self.

  • direction – The vertical direction the slur arches.

  • height – The ascent or descent of the curve given in absolute value. If omitted, a reasonable default is derived from other properties.

  • arch_length – The x-offset of the outer ascent or descent curve control points. Smaller values give tighter arches. If omitted, a reasonable default is derived from other properties

  • font – If provided, this overrides any font found in the ancestor chain.

  • brush – The brush to fill shapes with.

  • pen – The pen to draw outlines with.
