}
Expand description

Struct to represent optional parameters that can be passed to the arcs function.

Fields§

§strategy: ArcStrategy

Determines how the approximated arcs are computed. When maximizing the arcs, the algorithm may return incorrect arcs when the curve contains any small loops or segments that look like a very thin “U”. The enum options behave as follows:

  • Automatic: Maximize arcs until an erroneous approximation is found. Compute the arcs of the rest of the curve by first splitting on extremas to ensure no more erroneous cases are encountered.
  • FavorLargerArcs: Maximize arcs using the original algorithm from the Approximating a Bezier curve with circular arcs section of Pomax’s bezier curve primer. Erroneous arcs are possible.
  • FavorCorrectness: Prioritize correctness by first spliting the curve by its extremas and determine the arc approximation of each segment instead.

The default value is Automatic.

§error: f64

The error used for approximating the arc’s fit. The default is 0.5.

§max_iterations: usize

The maximum number of segment iterations used as attempts for arc approximations. The default is 100.
