Implementations§
source§impl PathStroker
impl PathStroker
sourcepub fn compute_resolution_scale(ts: &Transform) -> f32
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.
sourcepub fn stroke(
&mut self,
path: &Path,
stroke: &Stroke,
resolution_scale: f32,
) -> Option<Path>
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
.
