Struct CurveElem 

pub struct CurveElem {
    pub fill: Settable<Self, 0u8>,
    pub fill_rule: Settable<Self, 1u8>,
    pub stroke: Settable<Self, 2u8>,
    pub components: Vec<CurveComponent>,
}

A curve consisting of movements, lines, and Bézier segments.

At any point in time, there is a conceptual pen or cursor.

• Move elements move the cursor without drawing.
• Line/Quadratic/Cubic elements draw a segment from the cursor to a new position, potentially with control point for a Bézier curve.
• Close elements draw a straight or smooth line back to the start of the curve or the latest preceding move segment.

For layout purposes, the bounding box of the curve is a tight rectangle containing all segments as well as the point {(0pt, 0pt)}.

Positions may be specified absolutely (i.e. relatively to {(0pt, 0pt)}), or relative to the current pen/cursor position, that is, the position where the previous segment ended.

Bézier curve control points can be skipped by passing {none} or automatically mirrored from the preceding segment by passing {auto}.

Example

#curve(
  fill: blue.lighten(80%),
  stroke: blue,
  curve.move((0pt, 50pt)),
  curve.line((100pt, 50pt)),
  curve.cubic(none, (90pt, 0pt), (50pt, 0pt)),
  curve.close(),
)
