Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

distance(List<double> one, List<double> two) → double

Standard CIE 1976 delta E formula also takes the square root, unneeded here. This method is used by quantization algorithms to compare distance, and the relative ordering is the same, with or without a square root.

override

fromInt(int argb) → List<double>

Convert a color represented in ARGB to a 3-element array of Lab* coordinates of the color.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toInt(List<double> lab) → int

Convert a 3-element array to a color represented in ARGB.

override

toString() → String

A string representation of this object.
