Struct FontVariation 

pub struct FontVariation {
    pub axis: String,
    pub value: f64,
}

An axis tag and value that can be used to customize variable fonts.

Named constructors besides italic, optical_size, slant, width, and weight are not added until a caller needs them.

Fields

axis: String

The tag that identifies the design axis.

An axis tag must consist of 4 ASCII characters.

value: f64

The value assigned to this design axis.

Implementations

impl FontVariation

pub fn new(axis: impl Into<String>, value: f64) -> FontVariation

Creates a FontVariation object, which can be added to a text style to change the variable attributes of a font.

pub fn italic(value: f64) -> FontVariation

Variable font style. (ital)

pub fn optical_size(value: f64) -> FontVariation

Optical size optimization. (opsz)

pub fn slant(value: f64) -> FontVariation

Variable font slant. (slnt)

pub fn width(value: f64) -> FontVariation

Variable font width. (wdth)

pub fn weight(value: f64) -> FontVariation

Variable font weight. (wght)

pub fn lerp( a: Option<&FontVariation>, b: Option<&FontVariation>, t: f64, ) -> Option<FontVariation>

Linearly interpolates between two font variations.

If the two variations have different axis tags, the interpolation switches abruptly from one to the other at t=0.5. Otherwise, the value is interpolated.
