fill_ring_sector_aa

fn def fill_ring_sector_aa(mut canvas: Canvas, cx: Float64, cy: Float64, inner_radius: Float64, outer_radius: Float64, start_angle: Float64, end_angle: Float64, color: Color, supersample: Int = Int(4))

Anti-aliased fill_ring_sector: fill_arc_aa’s per-sample technique plus a second radius test, both of which must pass.

Scans the union of _arc_bounds’ boxes for the outer and inner radii, both with no center point; the outer radius alone is not enough.

Args:

• canvas (Canvas): Canvas to fill into.
• cx (Float64): Center x.
• cy (Float64): Center y.
• inner_radius (Float64): Ring’s inner edge, in pixels.
• outer_radius (Float64): Ring’s outer edge, in pixels. Must exceed inner_radius.
• start_angle (Float64): Sweep start, radians, 0 pointing along +x.
• end_angle (Float64): Sweep end, radians. Must be >= start_angle.
• color (Color): Fill color.
• supersample (Int): Sub-pixel grid side length per pixel (N -> N*N samples).
