Expand description

A DXF curve in the drawing’s plane.

Variants§

Line

A segment.

Fields

§start: Point2

Where it starts.

§end: Point2

Where it ends.

Arc

Counter-clockwise from start_angle to end_angle, in radians.

Fields

§centre: Point2

The centre.

§radius: f64

The radius.

§start_angle: f64

Where it starts, radians.

§end_angle: f64

Where it ends, radians.

Circle

A full circle.

Fields

§centre: Point2

The centre.

§radius: f64

The radius.

Ellipse

An ellipse or elliptic arc, parameters as DXF gives them: a full ellipse when they span two pi.

Fields

§centre: Point2

The centre.

§major: Vector2

The major axis’s end, relative to the centre.

§ratio: f64

Minor over major.

§start_param: f64

Start parameter.

§end_param: f64

End parameter.

Spline

A B-spline as written: degree, knots, control points and weights. A spline given only by fit points carries them as its control points and no knots.

Fields

§degree: usize

The degree.

§knots: Vec<f64>

The knot vector.

§control_points: Vec<Point2>

The control points, or the fit points where there are none.

§weights: Option<Vec<f64>>

The weights, for a rational spline.

§closed: bool

Whether the spline is closed.

Polyline

A POLYLINE or LWPOLYLINE: each vertex with the bulge of the segment that starts at it (the tangent of a quarter of the included angle, positive counter-clockwise).

Fields

§vertices: Vec<(Point2, f64)>

The vertices and their bulges.

§closed: bool

Whether the last vertex joins the first.

Trait Implementations§

impl Clone for DxfCurve

fn clone(&self) -> DxfCurve

Returns a duplicate of the value. Read more

1.0.0 (const: unstable) · Source§
