Implementations

impl PathStroker

pub fn new() -> PathStroker

Creates a new PathStroker.

pub fn compute_resolution_scale(ts: &Transform) -> f32

Computes a resolution scale.

Resolution scale is the “intended” resolution for the output. Default is 1.0.

Larger values (res > 1) indicate that the result should be more precise, since it will be zoomed up, and small errors will be magnified.

Smaller values (0 < res < 1) indicate that the result can be less precise, since it will be zoomed down, and small errors may be invisible.

pub fn stroke( &mut self, path: &Path, stroke: &Stroke, resolution_scale: f32, ) -> Option<Path>

Stokes the path.

Can be called multiple times to reuse allocated buffers.

resolution_scale can be obtained via compute_resolution_scale.

Trait Implementations

impl Clone for PathStroker

fn clone(&self) -> PathStroker

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for PathStroker

fn default() -> PathStroker

Returns the “default value” for a type.
