Constructor Detail

AdjustedColor

public AdjustedColor(java.awt.Color to)

A new colour

Parameters:

to - The base colour to use. This is used as a maximum for future generated colours.

AdjustedColor

public AdjustedColor(java.awt.Color to,
                     int max)

A new colour

Parameters:

to - The base colour to use. This is used as a maximum for future generated colours.

max - This value is used as a denominator in future interpolations

AdjustedColor

public AdjustedColor(java.awt.Color from,
                     java.awt.Color to,
                     int max)

A new colour

Parameters:

from - The lower end of the range of future colours interpolated from this AdjustedColour

to - The upper end of the range of future colours interpolated from this AdjustedColour

max - This value is used as a denominator in future interpolations

AdjustedColor

public AdjustedColor(java.awt.Color from,
                     java.awt.Color middle,
                     java.awt.Color to,
                     int max)

A new colour

Parameters:

from - The lower end of the range of future colours interpolated from this AdjustedColour

middle - A middle value in the range of future colours interpolated from this AdjustedColour

to - The upper end of the range of future colours interpolated from this AdjustedColour

max - This value is used as a denominator in future interpolations

Method Detail

generate

public static java.awt.Color generate(java.awt.Color c,
                                      int val,
                                      int max)

Generate a new color as a fraction of an existing one

Parameters:

c - The base colour

val - The numerator

max - The denominator

Returns:

return the colour scaled by val/code

generate

public static java.awt.Color generate(java.awt.Color from,
                                      java.awt.Color to,
                                      int val,
                                      int max)

INterpolate between colours

Parameters:

from - A colour

to - A second

val - The numerator

max - The denominator

Returns:

return a colour interpolated between from and to by val/code

generate

public static java.awt.Color generate(java.awt.Color from,
                                      java.awt.Color middle,
                                      java.awt.Color to,
                                      int val,
                                      int max)

Interpolate between colours. If val < max/2 generate a colour between from and middle else generate a colour between middle and to.

Parameters:

from - A starting colour

middle - A middle colour

to - An ending colour

val - The numerator

max - The denominator

Returns:

The interpolated colour

generate

public java.awt.Color generate(int val,
                               int max)

Generate a new colour

Parameters:

val - The numerator

max - The denominator

Returns:

the interpolated colour

generate

public java.awt.Color generate(int val)

Generate a new colour

Parameters:

val - The numerator

Returns:

an interpolated colour
