Struct ConvCurve 

pub struct ConvCurve<VS: VertexSource> { /* private fields */ }

Curve flattening converter.

Wraps a VertexSource and replaces curve3/curve4 commands with sequences of line_to vertices computed by the Curve3/Curve4 classes.

Port of C++ conv_curve<VertexSource>.

Implementations

impl<VS: VertexSource> ConvCurve<VS>

pub fn new(source: VS) -> Self

pub fn source(&self) -> &VS

pub fn source_mut(&mut self) -> &mut VS

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

Set the approximation scale for both curve types.

pub fn approximation_scale(&self) -> f64

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

Set the angle tolerance for both curve types.

pub fn angle_tolerance(&self) -> f64

pub fn set_cusp_limit(&mut self, v: f64)

Set the cusp limit (curve4 only — curve3 does not support cusp limit).

pub fn cusp_limit(&self) -> f64

Trait Implementations

impl<VS: VertexSource> VertexSource for ConvCurve<VS>

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.
