Enum of possible functions to calculate the distance between colors.

See https://en.wikipedia.org/wiki/Color_difference for details

Variants

DISTANCE_CIE76 = 0

The 1976 formula is the first formula that related a measured color difference to a known set of CIELAB coordinates.

DISTANCE_CIE94_GRAPHIC_ARTS = 1

The 1976 definition was extended to address perceptual non-uniformities.

DISTANCE_CIE94_TEXTILES = 2

DISTANCE_CIE2000 = 3

DISTANCE_CMC_1TO1 = 4

In 1984, the Colour Measurement Committee of the Society of Dyers and Colourists defined a difference measure, also based on the LCh color model.

DISTANCE_CMC_2TO1 = 5

DISTANCE_RGB = 6

Euclidean distance of rgb color space

DISTANCE_RGBL = 7

Euclidean distance of rgbl color space

Trait Implementations

impl Clone for DISTANCE_TYPE

fn clone(&self) -> DISTANCE_TYPE

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DISTANCE_TYPE

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

Formats the value using the given formatter.

impl From<DISTANCE_TYPE> for i32

fn from(v: DISTANCE_TYPE) -> Self

Converts to this type from the input type.

impl PartialEq for DISTANCE_TYPE

fn eq(&self, other: &DISTANCE_TYPE) -> 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<i32> for DISTANCE_TYPE

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for DISTANCE_TYPE

impl Eq for DISTANCE_TYPE

impl StructuralPartialEq for DISTANCE_TYPE
