Struct ScaledStyleMetrics 

pub struct ScaledStyleMetrics<'a, S: Scale> {
    metrics: &'a StyleMetrics,
    scale: S,
}

Style measurements in a caller’s own units.

Scaling is done when a measurement is requested. The italic angle and fixed-pitch flag have no length to scale and are returned unchanged.

Fields

metrics: &'a StyleMetrics

scale: S

Implementations

impl<'a, S: Scale> ScaledStyleMetrics<'a, S>

pub(crate) fn new(metrics: &'a StyleMetrics, scale: S) -> Self

pub fn subscript(&self) -> Option<ScriptMetrics<S::Value>>

Returns the suggested subscript em box and placement.

pub fn superscript(&self) -> Option<ScriptMetrics<S::Value>>

Returns the suggested superscript em box and placement.

pub fn underline(&self) -> Option<Decoration<S::Value>>

Returns the suggested underline position and thickness.

pub fn strike_through(&self) -> Option<Decoration<S::Value>>

Returns the suggested strikethrough position and thickness.

pub fn italic_angle(&self) -> Option<Fixed>

Returns the italic angle in degrees, unaffected by scaling.

pub fn is_fixed_pitch(&self) -> Option<bool>

Returns whether the font reports a fixed pitch.

fn scale_script(&self, script: ScriptMetrics) -> ScriptMetrics<S::Value>
