XYZ2RGB: convert from XYZ coordinates to CIE RGB coordinates

In colorscience: Color Science Methods and Data

Description

XYZ2RGB convert from XYZ coordinates to CIE RGB coordinates.

Usage

XYZ2RGB(XYZmatrix, illuminant = "D65", observer = 2, RefWhite
                 = get("XYZperfectreflectingdiffuser", envir = environment()),
                 RGBModel = "sRGB", RefWhiteRGB = get("whitepointsRGB", 
                 envir = environment()), gamma = NA,
                 RefWhiteIllum = get("XYZperfectreflectingdiffuser",
                 envir = environment()), CAT = "Bradford",
                 CATarray = get("ChromaticAdaptation", envir = environment()))

RefWhite	Reference White
RGBModel	RGB model
RefWhiteRGB	white points for RGB model
gamma	gamma
RefWhiteIllum	Reference perfect reflecting diffuser
CAT	CAT
