Struct ab_glyph::scale::PxScale

source ·
pub struct PxScale {
    pub x: f32,
    pub y: f32,
}
Expand description

Pixel scale.

This is the pixel-height of text.

Usually one uses x == y, but one may use a different ratio to stretch a font horizontally or vertically.

To convert pt size into pixel-scale see Font::pt_to_px_scale.

§Example

use ab_glyph::PxScale;

let uniform_scale_24px = PxScale::from(24.0);

Fields§

§x: f32

Horizontal scale in pixels.

§y: f32

Vertical scale in pixels.

By definition, this is the pixel-height of a font.
