Chroma.Scale

The attempt here is to provide something similar to https://gka.github.io/chroma.js/ but also idiomatic Elm.

Definition

domain : Nonempty Float -> Data -> Data

Set a new domain like [0,100] rather than the default [0,1]

correctLightness : Data -> Float -> Float

Given a data change the lightness value (need to be LAB).

type alias Data =

{ mode : Mode

, nanColor : Color

, spread : Float

, isFixed : Bool

, domainValues : Nonempty Float

, pos : Nonempty ( Float, Float )

, paddingValues : Nonempty Float

, useClasses : Bool

, colors : Nonempty ExtColor

, useOut : Bool

, min : Float

, max : Float

, useCorrectLightness : Bool

, gammaValue : Float

}

Configuration data used by most functions.

classes : List Color -> Int -> List Color

TBD

createData : Nonempty ExtColor -> Data -> Data

Setup new configuration with the given colours.

Sensible default configuration defaults: RGB, domain 0-1, pos 0, 1,and white and black colour range.

asRgba255 : ExtColor -> Rgba255Color

Takes a result from getColor and returns Integer (0-255) RGB values.

asRgba : ExtColor -> RgbaColor

Takes a result from getColor and returns Float (0-1) RGB values.
