Struct Stretch

pub struct Stretch(f32);

Visual width of a font– a relative change from the normal aspect ratio, typically in the range 0.5 to 2.0.

In variable fonts, this can be controlled with the wdth axis.

Implementations

impl Stretch

pub const ULTRA_CONDENSED: Self

Width that is 50% of normal.

pub const EXTRA_CONDENSED: Self

Width that is 62.5% of normal.

pub const CONDENSED: Self

Width that is 75% of normal.

pub const SEMI_CONDENSED: Self

Width that is 87.5% of normal.

pub const NORMAL: Self

Width that is 100% of normal.

pub const SEMI_EXPANDED: Self

Width that is 112.5% of normal.

pub const EXPANDED: Self

Width that is 125% of normal.

pub const EXTRA_EXPANDED: Self

Width that is 150% of normal.

pub const ULTRA_EXPANDED: Self

Width that is 200% of normal.

impl Stretch

pub const fn new(ratio: f32) -> Self

Creates a new stretch attribute with the given ratio.

fn from_width_class(width_class: u16) -> Self

Creates a new stretch attribute from the usWidthClass field of the OS/2 table.

pub const fn ratio(self) -> f32

Returns the stretch attribute as a ratio.

This is a linear scaling factor with 1.0 being “normal” width.

pub fn percentage(self) -> f32

Returns the stretch attribute as a percentage value.

This is generally the value associated with the wdth axis.

Trait Implementations

impl Clone for Stretch

fn clone(&self) -> Stretch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stretch

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

Formats the value using the given formatter.

impl Default for Stretch

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Stretch

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Stretch

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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