Class RGBColor

java.lang.Object
  extended by net.sourceforge.jiu.color.quantization.RGBColor
All Implemented Interfaces:
RGBIndex

public class RGBColor
extends Object
implements RGBIndex

Encapsulates a single color from RGB (red, green, blue) color space plus a frequency counter. Each of the three RGB samples is of type int. Also stores a counter of type int.

Constructor Detail

RGBColor

public RGBColor(int red,
                int green,
                int blue)
Creates an instance of this class and initializes it to the given intensity values. The internal color counter is set to zero.


RGBColor

public RGBColor(int red,
                int green,
                int blue,
                int counter)
Creates an instance of this class and initializes it to the given intensity values. Also sets the internal color counter to the given parameter.

Method Detail

compareTo

public int compareTo(RGBColor c,
                     int sortOrder)
Compares this color to the argument color, using the sortOrder argument (which is one of the three index values defined in RGBIndex. That way, the two sample values for one component (e.g. red if sortOrder == INDEX_RED) are compared.

Parameters:
c - the color to which this color is compared
sortOrder - the component used for the comparison
Returns:
relation between this color and the argument color

computeDistance

public static double computeDistance(int r1,
                                     int g1,
                                     int b1,
                                     int r2,
                                     int g2,
                                     int b2)
For two RGB triplets (r1, g1, b1) and (r2, g2, b2) this will return the distance between those colors in RGB color space.


equals

public boolean equals(Object obj)
Compares this color with another instance of RGBColor and returns true if all intensity values are equal, false otherwise.

Overrides:
equals in class Object

getCounter

public int getCounter()

getSample

public int getSample(int index)

toString

public String toString()
Overrides:
toString in class Object
