Struct VectorSurface 

pub struct VectorSurface { /* private fields */ }

Immutable prepared fill silhouette for deterministic area-uniform sampling. Images/strokes are not filled path regions. Paint alpha is not a density; zero-opacity groups are omitted, clips/holes and overlapping fills are honored.

Implementations

impl VectorSurface

pub fn area(&self) -> f64

Positive area of the union (overlap counted once).

pub fn triangles(&self) -> &[SurfaceTriangle]

Read-only continuous triangles, including clipped/holed decomposition.

pub fn tolerance(&self) -> f64

Requested maximum Wang curve-deviation tolerance in tree coordinates.

pub fn sample_points( &self, count: usize, seed: u64, ) -> Result<Vec<Point>, ValidationError>

Pure deterministic area selection and barycentric Halton sampling.

pub fn sample_colored_points( &self, count: usize, seed: u64, ) -> Result<Vec<(Point, [f32; 4])>, ValidationError>

Samples the same geometric points as sample_points and composites their retained fill stacks.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VectorSurface

fn fmt(&self, f: &mut Formatter<'_>) -> Result
