Struct FontData 

pub struct FontData {
    pub font: Cow<'static, [u8]>,
    pub index: u32,
    pub tweak: FontTweak,
}

A .ttf or .otf file and a font face index.

Fields

font: Cow<'static, [u8]>

The content of a .ttf or .otf file.

index: u32

Which font face in the file to use. When in doubt, use 0.

tweak: FontTweak

Extra scale and vertical tweak to apply to all text of this font.

Implementations

impl FontData

pub fn from_static(font: &'static [u8]) -> Self

pub fn from_owned(font: Vec<u8>) -> Self

pub fn tweak(self, tweak: FontTweak) -> Self

pub fn variation_axes(&self) -> Vec<FontVariationAxis>

The variation axes of this font, e.g. wght (weight) and wdth (width).

Use this to discover which axes a variable font supports, and their valid ranges, so a UI can offer the right knobs instead of making the user guess tags and values for FontTweak::coords.

Returns an empty list for non-variable (static) fonts, or if the font data fails to parse.
