Struct Curve3Div 

pub struct Curve3Div { /* private fields */ }

Recursive subdivision quadratic Bezier curve flattener.

Port of C++ agg::curve3_div.

Implementations

impl Curve3Div

pub fn new() -> Self

pub fn new_with_points( x1: f64, y1: f64, x2: f64, y2: f64, x3: f64, y3: f64, ) -> Self

pub fn reset(&mut self)

pub fn init(&mut self, x1: f64, y1: f64, x2: f64, y2: f64, x3: f64, y3: f64)

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

pub fn approximation_scale(&self) -> f64

pub fn set_angle_tolerance(&mut self, a: f64)

pub fn angle_tolerance(&self) -> f64

Trait Implementations

impl Default for Curve3Div

fn default() -> Self

Returns the “default value” for a type.

impl VertexSource for Curve3Div

fn rewind(&mut self, _path_id: u32)

Reset the vertex source to the beginning of the given path. path_id selects which sub-path to iterate (0 for the first/only path).

fn vertex(&mut self, x: &mut f64, y: &mut f64) -> u32

Return the next vertex. Writes coordinates to x and y, returns a path command. Returns PATH_CMD_STOP when iteration is complete.
