All Implemented Interfaces:

Shape, Serializable, Cloneable

public class CieXyPlot
extends Path2D.Double

This class renders the famous CIE xy-chromaticity diagram, also known as the "horeseshoe" curve, delineating the range of visible colors in the xy-diagram. The shape is created in a square canvas whose size can be specified. The result is "upside down", i.e., the vertical coordinate runs from top to bottom.

Field Details

CIE1964xyz

public static final double[][] CIE1964xyz

CIE 1964 10-deg chromaticity coordinates. Copied from http://www.cvrl.org/ccs.htm. The entry format is [ λ, x(λ), y(λ), z(λ)], with wavelength λ (in nm) and xyz chromaticity coordinates. The array is truncated above 720nm, thereby skipping the "dangling" measurements.

Constructor Details

CieXyPlot

public CieXyPlot(double CanvasSize)

Constructor, creates a xy-diagram in a canvas with the specified size.

Parameters:

CanvasSize - the size of the canvas
