Struct ab_glyph::scale::PxScale

pub struct PxScale {
    pub x: f32,
    pub y: f32,
}

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.

Implementations

impl PxScale

pub fn round(self) -> Self

Returns a PxScale with both x & y scale values set to the nearest integer.

Trait Implementations

impl Clone for PxScale

fn clone(&self) -> PxScale

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PxScale

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

Formats the value using the given formatter.

impl From<f32> for PxScale

fn from(s: f32) -> Self

Uniform scaling where x & y are the same.

impl PartialEq for PxScale

fn eq(&self, other: &PxScale) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PxScale

fn partial_cmp(&self, other: &PxScale) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
