svg_path/winding_field

Winding-field sampling shared by arrangement operations.

Values

nonzero_level_at

pub fn nonzero_level_at(
  point: svg_path.Point,
  within path: svg_path.Path,
  options options: svg_path.ContainmentOptions,
) -> Result(Int, svg_path.Error)

Return the signed Nonzero winding level at a point. Boundary samples fall back to filled/not-filled because a signed winding is undefined there.

segment_side_nonzero_levels

</>

pub fn segment_side_nonzero_levels(
  segment: svg_path.Segment,
  within path: svg_path.Path,
  tolerance tolerance: Float,
  options options: svg_path.ContainmentOptions,
) -> Result(#(Int, Int), svg_path.Error)

Sample the Nonzero winding field immediately on the geometric left and right of a segment. The first result is the left-side level.
