simplify

  • simplify(points, tolerance?, highestQuality?): T[]

  • Simplify an array of points with an optional tolerance.

    Parameters

    • points: Point<T, P>[]

      Array of points to simplify.

    • tolerance: number = 1

      Tolerance in squared units.

    • highestQuality: boolean = false

      Flag to enable highest quality simplification.

    Returns T[]

    Simplified array of points.

    Example

    const simplified = simplifyPath.simplify([{ x: 0, y: 0 }, { x: 1, y: 1 }, { x: 2, y: 2 }], 1);
