Trait Implementations

impl Default for CIELab

fn default() -> CIELab

Returns the "default value" for a type.

impl Copy for CIELab

impl From<CIELCh> for CIELab

fn from(f: CIELCh) -> CIELab

Performs the conversion.

impl PartialEq<CIELab> for CIELab

fn eq(&self, __arg_0: &CIELab) -> bool

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

fn ne(&self, __arg_0: &CIELab) -> bool

This method tests for !=.

impl Debug for CIELab

fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Clone for CIELab

fn clone(&self) -> CIELab

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CIELabExt for CIELab

fn cie2000_delta_e(&self, other: &CIELab, kl: f64, kc: f64, kh: f64) -> f64

Delta-E 2000 is the first major revision of the dE94 equation.

fn cie94_delta_e(&self, other: &CIELab) -> f64

A technical committee of the CIE (TC1-29) published an equation in 1995 called CIE94. The equation is similar to CMC but the weighting functions are largely based on RIT/DuPont tolerance data derived from automotive paint experiments where sample surfaces are smooth. It also has ratios, labeled kL (lightness) and Kc (chroma) and the commercial factor (cf) but these tend to be preset in software and are not often exposed for the user (as it is the case in Little CMS). Returns: The CIE94 dE metric value.

fn bfd_delta_e(&self, other: &CIELab) -> f64

BFD delta E metric.

fn delta_e(&self, other: &CIELab) -> f64

The dE76 metric value.

fn cmc_delta_e(&self, other: &CIELab, k: f64, c: f64) -> f64

In 1984 the CMC (Colour Measurement Committee of the Society of Dyes and Colourists of Great Britain) developed and adopted an equation based on LCH numbers.

fn desaturate(&mut self, amin: f64, amax: f64, bmin: f64, bmax: f64) -> bool

amin, amax, bmin, bmax: boundaries of gamut rectangle

fn encoded(&self) -> [u16; 3]

Encodes a Lab value, from a CIELab value to ICC v4 convention.

fn encoded_v2(&self) -> [u16; 3]

Encodes a Lab value, from a CIELab value to ICC v2 convention.

fn from_encoded(icc: &[u16; 3]) -> Self

Decodes a Lab value, encoded on ICC v4 convention

fn from_encoded_v2(icc: &[u16; 3]) -> Self

Decodes a Lab value, encoded on ICC v2 convention

fn to_xyz(&self, white_point: &CIEXYZ) -> CIEXYZ

Colorimetric space conversion.
