Struct Dlch 

pub struct Dlch {
    pub l: f64,
    pub c: f64,
    pub h: f64,
    pub alpha: Option<f64>,
}

DIN99o LCh. l is in 0..100, c is non-negative, h is in degrees.

Fields

l: f64

Lightness in 0..100.

c: f64

Chroma.

h: f64

Hue in degrees.

alpha: Option<f64>

Optional alpha in 0..1.

Trait Implementations

impl Clone for Dlch

fn clone(&self) -> Dlch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ColorSpace for Dlch

const MODE: &'static str = "dlch"

Stable identifier for this space (matches culori’s mode string).

const CHANNELS: &'static [&'static str]

The space’s natural channels in canonical order. Alpha is excluded: it is a universal meta-channel accessed via alpha rather than a channel of any particular space.

fn alpha(&self) -> Option<f64>

Returns the alpha channel, if set.

fn with_alpha(self, alpha: Option<f64>) -> Self

Returns a copy of self with the given alpha.

fn to_xyz65(&self) -> Xyz65

Convert this color into the XYZ D65 hub space.

fn from_xyz65(xyz: Xyz65) -> Self

Construct a color of this space from the XYZ D65 hub space.

impl Debug for Dlch

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

Formats the value using the given formatter.

impl From<Dlch> for Color

fn from(c: Dlch) -> Self

Converts to this type from the input type.

impl From<Rgb> for Dlch

Direct Rgb → Dlch matching culori’s achromatic-RGB snap. See the From<Rgb> for Dlab doc for why the snap is necessary.

fn from(c: Rgb) -> Self

Converts to this type from the input type.

impl PartialEq for Dlch

fn eq(&self, other: &Dlch) -> 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<Color> for Dlch

type Error = ColorVariantMismatch

The type returned in the event of a conversion error.

fn try_from(c: Color) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Dlch

impl StructuralPartialEq for Dlch
