cmykToXyz

public final DoubleArray cmykToXyz(Context context, @Size(value = 4) DoubleArray cmykIn, @Size(value = 3) DoubleArray refOut, Boolean bpc)

Calculates XYZ value from CMYK input using built-in lookup tables

Return

XYZ value output, unity scale (element order X, Y, Z)

Parameters

context

Context

cmykIn

CMYK colour input, unity scale (element order C, M, Y, K)

refOut

Reference white value for XYZ output, unity scale (element order X, Y, Z)

bpc

set to true to perform black point compensation
