Properties​

Data​

The path data to render. Define it by combining segments such as line segments and Bézier curves.

  • Type: Geometry?
  • Default: Empty PathGeometry
  • Animatable: No

Common properties​

This object inherits from Shape and exposes the common properties declared on its base classes.

Path geometry structure​

The default Data value is a PathGeometry. A PathGeometry holds a list of PathFigure values, and each figure holds a list of PathSegment values.

PathGeometry​

  • Figures: IList<PathFigure>, default empty list. Animatable: No.

PathFigure​

  • Start Point (StartPoint): Point, default (NaN, NaN), animatable. The figure's starting point.
  • Is Closed (IsClosed): bool, default false, animatable. When true, the figure is closed back to the start point.
  • Segments: IList<PathSegment>, default empty list.

Path segments​

The Segments list accepts any PathSegment. Each segment defines how the curve continues from the previous point.

Line Segment​

Adds a straight line to the next point.

  • Point: Point, default (0, 0), animatable. End point of the line.

Quadratic Bézier Segment​

Adds a quadratic Bézier curve.

  • Control Point (ControlPoint): Point, default (0, 0), animatable.
  • End Point (EndPoint): Point, default (0, 0), animatable.

Cubic Bézier Segment​

Adds a cubic Bézier curve.

  • Control Point 1 (ControlPoint1): Point, default (0, 0), animatable.
  • Control Point 2 (ControlPoint2): Point, default (0, 0), animatable.
  • End Point (EndPoint): Point, default (0, 0), animatable.

Arc Segment​

Adds an elliptical arc.

  • Radius: Size, default (0, 0), animatable. X / Y radii of the arc's ellipse.
  • Rotation Angle (RotationAngle): float, default 0, animatable. Rotation of the ellipse in degrees.
  • Is Large Arc (IsLargeArc): bool, default false, animatable. When true, the longer (≥180°) arc is drawn.
  • Sweep Clockwise (SweepClockwise): bool, default true, animatable. Sweep direction.
  • Point: Point, default (0, 0), animatable. End point of the arc.

Conic Segment​

Adds a rational quadratic curve (used to express true circular / elliptical arcs).

  • Control Point (ControlPoint): Point, default (0, 0), animatable.
  • End Point (EndPoint): Point, default (0, 0), animatable.
  • Weight: float, default 1, animatable. Higher weights pull the curve closer to the control point.

Usage​

Build complex shapes — logos, icons, custom callouts — by composing path segments. Fill and stroke are configured the same way as on the other shape objects.
