Struct FontExtent 

pub struct FontExtent {
    pub ascent: f32,
    pub descent: f32,
    pub line_gap: f32,
}

The font’s own vertical extent, in the same unit as the line height.

ascent and descent are both positive distances from the baseline, which is the sign convention AOSP states its rule in and the opposite of the one ab_glyph reports descent in.

Fields

ascent: f32

descent: f32

line_gap: f32

hhea.lineGap. Only read when a style asks for font padding.

Implementations

impl FontExtent

pub fn new(ascent: f32, descent: f32, line_gap: f32) -> Self

pub fn natural(self) -> f32

Ascent plus descent — the height the font needs with no leading at all.
