Class AdvancedColorScheme

java.lang.Object
  edu.washington.biostr.sig.volume.colors.ColorScheme
      edu.washington.biostr.sig.volume.colors.AdvancedColorScheme

public class AdvancedColorScheme
extends ColorScheme

An AdvancedColorScheme allows the user to create a scheme that flows from one color to another (and maybe to another, etc) by doing a piecewise interpolation.
The most convenient way to use it is by calling the getWarm() or getCold() methods.

Constructor Summary

AdvancedColorScheme()
Create a simple grayscale color scheme.

int	hashCode()
void	setColor(int i, Color color, double start, double end) Add a color that will be blended with the existing color.
void	setComposite(int composite) Use one of AlphaComposite's values to mix this in with any existing colors on a palatte based on the rule and alpha level.

Constructor Detail

AdvancedColorScheme

public AdvancedColorScheme()

Create a simple grayscale color scheme.

AdvancedColorScheme

public AdvancedColorScheme(int numColors)

Interpolate across the given number of colors (first from black to color 1, then from from color 1 to color 2, etc.)

Parameters:

numColors - The number of colors to interpolate across.

Method Detail

setComposite

public void setComposite(int composite)

Use one of AlphaComposite's values to mix this in with any existing colors on a palatte based on the rule and alpha level.

Parameters:

composite - The composite value from AlphaComposite

setColor

public void setColor(int i,
                     Color color,
                     double start,
                     double end)

Add a color that will be blended with the existing color.

Parameters:

i - The color index.

color - The color.

start - The starting value to blend this (between 0 and 1)

end - The ending value to blend this (between 0 and 1)

getRGB

public int[] getRGB(double value)

Description copied from class: ColorScheme

Get an RGBA value as 4 ints {R, G, B, A}

Overrides:

getRGB in class ColorScheme

Returns:

A 4 int RGBA value.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getComposite

public AlphaComposite getComposite()

getWarm

public static AdvancedColorScheme getWarm(double alpha)

Generate a color scheme that flows from black to red to yellow to white (it has a warm feel and a large level of granularity).

Parameters:

alpha - The level of opacity

Returns:

A scheme that generates warm colors.

getCold

public static AdvancedColorScheme getCold(double alpha)

Generate a color scheme that flows from black to blue to cyan to white (it has a cold feel and a large level of granularity).

Parameters:

alpha - The level of opacity

Returns:

A scheme that generates cold colors.

getColor

public static AdvancedColorScheme getColor(Color color,
                                           String name)

Generate a color scheme for a single color.

Parameters:

color - The desired color

name - The name of this scheme

Returns:

A color scheme for a single color.

hashCode

public int hashCode()

Overrides:

hashCode in class Object
