Enum VerticalPosition 

pub enum VerticalPosition {
    Normal,
    Superscript {
        size_ratio: f32,
        baseline_rise: f32,
    },
    Subscript {
        size_ratio: f32,
        baseline_drop: f32,
    },
}

Vertical text positioning for subscript/superscript effects.

Variants

Normal

Normal baseline.

Superscript

Superscript: smaller text raised above the baseline.

Fields

size_ratio: f32

Font size ratio (e.g. 0.6 for 60% of base size).

baseline_rise: f32

Baseline rise in pixels (positive = upward).

Subscript

Subscript: smaller text lowered below the baseline.

Fields

size_ratio: f32

Font size ratio (e.g. 0.6 for 60% of base size).

baseline_drop: f32

Baseline drop in pixels (positive = downward).

Implementations

impl VerticalPosition

pub fn effective_size(&self, base_px: f32) -> f32

Compute the actual font size for this position given a base size.

pub fn baseline_adjustment(&self, _base_px: f32) -> f32

Compute the Y baseline adjustment in pixels (positive = upward).

Trait Implementations

impl Clone for VerticalPosition

fn clone(&self) -> VerticalPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VerticalPosition

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

Formats the value using the given formatter.

impl Default for VerticalPosition

fn default() -> VerticalPosition

Returns the “default value” for a type.

impl PartialEq for VerticalPosition

fn eq(&self, other: &VerticalPosition) -> 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.

impl Copy for VerticalPosition
