Expand description

Conversion from endpoint parameterization to center parameterization.

SVG path data specifies elliptical arcs in terms of their endpoints, but they are easier to process if they are converted to a center parameterization.

When attempting to compute the center parameterization of the arc, out of range parameters may see an arc omitted or treated as a line.

Variants§

§

CenterParameters

Fields

§center: (f64, f64)

Center of the ellipse.

§radii: (f64, f64)

Radii of the ellipse (corrected).

§theta1: f64

Angle of the start point.

§delta_theta: f64

Delta angle to the end point.

Center parameterization of the arc.

§

LineTo

Treat the arc as a line to the end point.

§

Omit

Omit the arc.
