Enum TextScaler 

pub enum TextScaler {
    Linear(f32),
    Piecewise {
        points: Vec<(f32, f32)>,
    },
}

Variants

Linear(f32)

Compatibility form and the correct choice for fixed application scaling.

Piecewise

Piecewise-linear accessibility scaling. Points are (font_size, scale) and are interpolated in ascending font-size order.

Fields

points: Vec<(f32, f32)>

Implementations

impl TextScaler

pub fn linear(scale_factor: f32) -> Self

pub fn piecewise(points: impl IntoIterator<Item = (f32, f32)>) -> Self

pub fn accessibility(scale_factor: f32) -> Self

Builds the nonlinear accessibility curve used for a host text-scale preference. Small body text receives the full requested scale while large display text grows more gradually to preserve useful viewport space. Values at or below the default scale remain linear.

pub fn scale(&self, font_size: f32) -> f32

pub fn scale_factor(&self) -> f32
