micycle.peasygradients.colorspace.XYZ

All Implemented Interfaces:

ColorSpaceTransform

public final class XYZ
extends Object
implements ColorSpaceTransform

CIE XYZ (aka CIE 1931) (aka tristimulus values) is a device-invariant representation of color. It serves as a standard reference against which many other color spaces are defined.

public XYZ()

Method Detail

fromRGB

public double[] fromRGB(double[] rgb)

Description copied from interface: ColorSpaceTransform

Converts an RGB color into the corresponding color in the target color space.

Specified by:

fromRGB in interface ColorSpaceTransform

Parameters:

rgb - [R,G,B] where values are 0...1.0

Returns:

toRGB

public double[] toRGB(double[] xyz)

Description copied from interface: ColorSpaceTransform

Converts a color from the implementing color space to RGB. Implementations should focus on optimizing this conversion process for efficiency.

Specified by:

toRGB in interface ColorSpaceTransform

@Deprecated
public static double[] xyz2rgbQuick(double[] xyz)

Deprecated.

Fast, negligible visual effect inaccuracy.

Parameters:

xyz - [X,Y,Z]

Returns:

[R,G,B] where values are 0...1.0

xyz2rgbVeryQuick

@Deprecated
public static double[] xyz2rgbVeryQuick(double[] xyz)

Deprecated.

Very fast, but visible inaccuracies

Parameters:

xyz - [X,Y,Z]
