Struct MathStroke 

pub struct MathStroke { /* private fields */ }

Stroke geometry calculator.

Computes cap and join vertices for stroked paths. Output vertices are pushed into a Vec<PointD> consumer.

Port of C++ agg::math_stroke<VC>.

Implementations

impl MathStroke

pub fn new() -> Self

pub fn set_line_cap(&mut self, lc: LineCap)

pub fn line_cap(&self) -> LineCap

pub fn set_line_join(&mut self, lj: LineJoin)

pub fn line_join(&self) -> LineJoin

pub fn set_inner_join(&mut self, ij: InnerJoin)

pub fn inner_join(&self) -> InnerJoin

pub fn set_width(&mut self, w: f64)

pub fn width(&self) -> f64

pub fn set_miter_limit(&mut self, ml: f64)

pub fn miter_limit(&self) -> f64

pub fn set_miter_limit_theta(&mut self, t: f64)

pub fn set_inner_miter_limit(&mut self, ml: f64)

pub fn inner_miter_limit(&self) -> f64

pub fn set_approximation_scale(&mut self, s: f64)

pub fn approximation_scale(&self) -> f64

pub fn calc_cap( &self, vc: &mut Vec<PointD>, v0: &VertexDist, v1: &VertexDist, len: f64, )

Calculate cap vertices at a line endpoint.

Output is pushed to vc. v0 is the endpoint, v1 is the adjacent vertex, len is the distance between them.

pub fn calc_join( &self, vc: &mut Vec<PointD>, v0: &VertexDist, v1: &VertexDist, v2: &VertexDist, len1: f64, len2: f64, )

Calculate join vertices at the junction of two line segments.

v0→v1 is the first segment, v1→v2 is the second. len1 and len2 are the segment lengths.

Trait Implementations

impl Default for MathStroke

fn default() -> Self

Returns the “default value” for a type.
