Struct Shape 

pub struct Shape { /* private fields */ }

Multipolygon ink / halo geometry.

Implementations

impl Shape

pub fn empty() -> Self

pub fn is_empty(&self) -> bool

pub fn from_ring(ring: &[(f64, f64)]) -> Self

Single exterior ring (lib-simplify cleans winding / collinear).

pub fn from_contours_evenodd(contours: &[Vec<(f64, f64)>]) -> Self

Independent contours → even-odd / XOR shape (glyph counters).

pub fn disk(cx: f64, cy: f64, radius: f64, quad_segs: u32) -> Self

pub fn capsule(x1: f64, y1: f64, x2: f64, y2: f64, radius: f64) -> Self

pub fn polyline_buffer(pts: &[(f64, f64)], radius: f64) -> Self

pub fn multipoint_buffer(pts: &[(f64, f64)], radius: f64) -> Self

pub fn annular(cx: f64, cy: f64, r: f64, stroke_width: f64) -> Self

pub fn union(&self, other: &Self) -> Self

pub fn difference(&self, other: &Self) -> Self

pub fn xor(&self, other: &Self) -> Self

pub fn buffer(&self, dist: f64) -> Self

Outline offset (dist may be negative).

pub fn simplify(&self) -> Self

i_overlay::SimplifyShape (collinear cleanup; holes stay valid).

pub fn point_count(&self) -> usize

pub fn halo(&self, dist: f64) -> Self

White knockout: simplify, then outline offset.

pub fn has_holes(&self) -> bool

pub fn translate(&self, dx: f64, dy: f64) -> Self

pub fn scale(&self, sx: f64, sy: f64, ox: f64, oy: f64) -> Self

pub fn bounds(&self) -> Option<(f64, f64, f64, f64)>

pub fn area(&self) -> f64

pub fn centroid(&self) -> Option<(f64, f64)>

pub fn contains(&self, x: f64, y: f64) -> bool

pub fn to_svg_d(&self) -> String

pub fn horizontal_span_at(&self, y: f64) -> f64

Leftmost horizontal chord length at y (stem-width helper).

pub fn polygons_rings(&self) -> Vec<(Vec<(f64, f64)>, Vec<Vec<(f64, f64)>>)>

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.

impl Default for Shape

fn default() -> Shape

Returns the “default value” for a type.
