Zcam

data class Zcam(brightness: Double, lightness: Double, colorfulness: Double, chroma: Double, hue: Double, saturation: Double, vividness: Double, blackness: Double, whiteness: Double, viewingConditions: Zcam.ViewingConditions) : Color, Lch

A color modeled by the ZCAM color appearance model, which provides a variety of perceptual color attributes. This color appearance model is designed with HDR in mind so it only accepts absolute CIE XYZ values scaled by the absolute luminance of the modeled display, unlike SDR color spaces that accept relative luminance.

Most attributes are optional in the constructor because don't need to be present together. All ZCAM colors must have: - brightness OR lightness - colorfulness OR chroma OR saturation OR vividness OR blackness OR whiteness - hue - viewing conditions

Constructors

Zcam

fun Zcam(brightness: Double = Double.NaN, lightness: Double = Double.NaN, colorfulness: Double = Double.NaN, chroma: Double = Double.NaN, hue: Double, saturation: Double = Double.NaN, vividness: Double = Double.NaN, blackness: Double = Double.NaN, whiteness: Double = Double.NaN, viewingConditions: Zcam.ViewingConditions)

Types

ChromaSource

enum ChromaSource : Enum<Zcam.ChromaSource>

ZCAM attributes that can be used to calculate chroma (colorfulness) in the inverse model.

Companion

object Companion

LuminanceSource

enum LuminanceSource : Enum<Zcam.LuminanceSource>

ZCAM attributes that can be used to calculate luminance in the inverse model.

ViewingConditions

data class ViewingConditions(surroundFactor: Double, adaptingLuminance: Double, backgroundLuminance: Double, referenceWhite: CieXyzAbs)

The conditions under which a color modeled by ZCAM will be viewed. This is defined by the luminance of the adapting field, luminance of the background, and surround factor.
