Struct TextPath 

pub struct TextPath {
    pub control_points: Vec<(f32, f32)>,
}

A Bezier spline path for positioning and rotating glyphs along arbitrary curves.

Contract

The path is constructed from control points. The sample method interpolates along the path at normalized parameter t (0.0 to 1.0) and returns the 2D position and the tangent rotation angle in radians for orienting characters correctly.

Fields

control_points: Vec<(f32, f32)>

Control points for the Bezier spline segments.

Implementations

impl TextPath

pub fn new(control_points: Vec<(f32, f32)>) -> Self

Create a new text path from control points.

pub fn sample(&self, t: f32) -> ((f32, f32), f32)

Sample the position and tangent rotation angle (radians) at normalized parameter t (0.0..=1.0).

Trait Implementations

impl Clone for TextPath

fn clone(&self) -> TextPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextPath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TextPath

fn eq(&self, other: &TextPath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
