IsClosed

IsClosed() -> bool

Check if spline is closed ( first/last points are equal )

Returns:

• bool –

  closed spline true/false

Reverse

Reverse()

Reverse of current spline

Method reverse Spline using reverse from PolyPoints and swapping tangents.

SetEndVector

SetEndVector(vec: Vector2D)

Set end vector.

Parameters:

• vec (Vector2D) –

  new end vector.

  new start vector.

__eq__

__eq__(spline: Spline2D) -> object

Comparison of splines without tolerance.

Be careful, this method work without tolerance!

Parameters:

• spline (Spline2D) –

  Compared spline.

Returns:

• object –

  True when splines are equal, otherwise false.

__init__ overloaded
