Enum Space

pub enum Space {
    SRGB,

    XYZ,
    CIELAB,
    CIELCH,
    OKLAB,
    OKLCH,

}

Defines colorspace pixels will take.

Variants

SRGB

Gamma-corrected sRGB.

HSV

Hue Saturation Value.

A UCS typically preferred for modern applications

LRGB

Linear RGB. IEC 61966-2-1:1999 transferred

XYZ

1931 CIE XYZ @ D65.

CIELAB

CIE LAB. Lightness, red/green chromacity, yellow/blue chromacity.

1976 UCS with many known flaws. Most other LAB spaces derive from this

CIELCH

CIE LCH(ab). Lightness, Chroma, Hue

Cylindrical version of CIE LAB.

OKLAB

Oklab

https://bottosson.github.io/posts/oklab/

2020 UCS, used in CSS Color Module Level 4

OKLCH

Cylindrical version of OKLAB.

JZAZBZ

JzAzBz

https://opg.optica.org/oe/fulltext.cfm?uri=oe-25-13-15131

2017 UCS, intended for uniform hue and HDR colors

JZCZHZ

Cylindrical version of JzAzBz

Implementations

impl Space

pub const ALL: &'static [Space]

All color spaces

pub const UCS: &'static [Space]

Uniform color spaces

pub const UCS_POLAR: &'static [Space]

Uniform color spaces in cylindrical/polar format

pub const TRI: &'static [Space]

RGB/Tristimulus color spaces

pub fn channels(&self) -> [char; 3]

Returns 3 channels letters for user-facing colorspace controls

pub const fn srgb_quants(&self) -> [[f32; 3]; 101]

Retrieves a map from a given Space back to SRGB.

This is useful for things like creating adjustable values in Space that represent most of the SRGB range without clipping. Wrapping Hue values are set to f32::INFINITY

Trait Implementations

impl Clone for Space

fn clone(&self) -> Space

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Space

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

Formats the value using the given formatter.

impl Display for Space

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

Formats the value using the given formatter.

impl PartialEq for Space

fn eq(&self, other: &Space) -> 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 TryFrom<&str> for Space

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, ()>

Performs the conversion.

impl TryFrom<*const i8> for Space

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: *const c_char) -> Result<Self, ()>

Performs the conversion.

impl Copy for Space

impl Eq for Space

impl StructuralPartialEq for Space
