Struct TransSinglePath 

pub struct TransSinglePath { /* private fields */ }

Single-path coordinate transformation.

Stores a path as a sequence of vertices with cumulative distances. transform() maps x → distance-along-path, y → perpendicular offset. Used by ConvTransform with ConvSegmentator for text-on-path effects.

Implementations

impl TransSinglePath

pub fn new() -> Self

pub fn base_length(&self) -> f64

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

pub fn preserve_x_scale(&self) -> bool

pub fn set_preserve_x_scale(&mut self, f: bool)

pub fn reset(&mut self)

pub fn move_to(&mut self, x: f64, y: f64)

pub fn line_to(&mut self, x: f64, y: f64)

pub fn add_path<VS: VertexSource>(&mut self, vs: &mut VS, path_id: u32)

Build the path from a VertexSource.

pub fn finalize_path(&mut self)

Finalize the path — compute cumulative distances and prepare for transform.

pub fn total_length(&self) -> f64

Total length of the path (or base_length if set).
