- class neoscore.western.pedal_line.PedalLine
A line-style pedal marking with optional half-lift (^) marks.
The mark begins with an upward crook, continues as a horizontal line interrupted with optional half-lift upward triangular marks, and terminates with another upward crook.
The object’s position is that of the top of the opening crook; this y-axis position is also the height two which the half-lift marks extend. The main line of the path is drawn 1 staff unit below this position.
A list of half-lift x-axis positions may be provided as either simple x-axis Unit values (relative to the line’s start position) or as 2-tuples of x-axis positions and position parents:
>>> PedalLine(start=(Mm(10), staff.unit(8)), start_parent=staff, ... end_x=Mm(200), end_parent=None, ... half_lift_positions=[ ... Mm(20), # Relative to start_parent ... Mm(40), # Relative to start_parent ... (Mm(1), some_chord)] # 1 mm right of some_chord ... )
While this is a path, it requires a music font from which to derive its appearance.
- __init__(start: PointDef, start_parent: PositionedObject, end_x: Unit, end_parent: Optional[PositionedObject] = None, half_lift_positions: List[Unit | Tuple[Unit, PositionedObject]] = None, font: Optional[MusicFont] = None)
start – The starting position of the pedal line.
start_parent – The parent for the starting position. If no font is given, this or one of its ancestors must implement
end_x – x position of the end point relative to end_parent
end_parent – parent for end_x
half_lift_positions – A list of x-axis positions along the line where half lift notches should be drawn.
font – If provided, this overrides any font found in the ancestor chain.
