Struct LineProfileAa 

pub struct LineProfileAa { /* private fields */ }

Anti-aliased line width profile.

Port of C++ line_profile_aa. Builds a lookup table mapping perpendicular distance from line center → coverage value, with configurable width and gamma correction.

Implementations

impl LineProfileAa

pub fn new() -> Self

pub fn with_width(w: f64) -> Self

Create with a specific width.

pub fn min_width(&self) -> f64

pub fn smoother_width(&self) -> f64

pub fn subpixel_width(&self) -> i32

pub fn set_min_width(&mut self, w: f64)

pub fn set_smoother_width(&mut self, w: f64)

pub fn set_width(&mut self, w: f64)

Set the line width (in pixels). Port of C++ line_profile_aa::width.

pub fn set_gamma<F: Fn(f64) -> f64>(&mut self, gamma_fn: F)

Apply gamma function.

pub fn value(&self, dist: i32) -> u8

Lookup coverage for a given perpendicular distance.
