Struct Lab

#[repr(C)]
pub struct Lab {
    pub l: f32,
    pub a: f32,
    pub b: f32,
}

Holds CIE LAB values

Fields

l: f32

l: lightness component (0 to 100)

a: f32

a: green (negative) and red (positive) component.

b: f32

b: blue (negative) and yellow (positive) component

Implementations

impl Lab

pub const fn new(l: f32, a: f32, b: f32) -> Self

Create a new CIELAB color.

Arguments

• l: lightness component (0 to 100).
• a: green (negative) and red (positive) component.
• b: blue (negative) and yellow (positive) component.

impl Lab

pub fn from_pcs_xyz(xyz: Xyz) -> Self

Converts to CIE Lab from CIE XYZ for PCS encoding

pub fn from_xyz(xyz: Xyz) -> Self

Converts to CIE Lab from CIE XYZ

pub fn to_pcs_xyz(self) -> Xyz

Converts CIE Lab into CIE Xyz for PCS encoding

pub fn to_xyz(self) -> Xyz

Converts CIE Lab into CIE Xyz

pub fn desaturate_pcs(self) -> Lab

Desaturates out of gamut PCS encoded LAB

Trait Implementations

impl Clone for Lab

fn clone(&self) -> Lab

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lab

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

Formats the value using the given formatter.

impl Default for Lab

fn default() -> Lab

Returns the “default value” for a type.

impl PartialEq for Lab

fn eq(&self, other: &Lab) -> 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 Lab

fn partial_cmp(&self, other: &Lab) -> 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.
