Package micycle.peasygradients.colorspace

Class IPT

java.lang.Object

micycle.peasygradients.colorspace.IPT

All Implemented Interfaces:

ColorSpaceTransform

public final class IPT
extends Object
implements ColorSpaceTransform

The IPT color space is similar in model to CIELAB color space but is more uniform in perceived hue. Published by Ebner and Fairchild in 1998.

IPT opponents: I light–dark; P red–green, T yellow–blue.

Method Detail

toRGB

public double[] toRGB(double[] IPT)

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

Parameters:

IPT - an array representing the color in the implementing color space. The specific meaning and length of this array depend on the color space.

Returns:

an array of three doubles representing the color in RGB, with each component normalized to the range [0, 1]. The output may exceed this range before display calibration or clipping is applied.

LMStoXYZInverse

public static double[] LMStoXYZInverse(double[] IPT)

Reverses #LMStoXYZ(double[])

Parameters:

IPT -

Returns:

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 - an array of three doubles representing the red, green, and blue components of the color, each normalized to the range [0, 1]

Returns:

an array of doubles representing the color in the target color space. The length and interpretation of this array depend on the specific color space.
