Gradient

public Gradient()

Constructs a new gradient color map.

Method Details

interpolateColors

public void interpolateColors(T[] gradient,
 Color start,
 int first,
 Color end,
 int last)

Utility method for creating a smooth gradient ranging from color start to color end in last-first steps. The color gradient is stored in the array gradient from elements first to last (inclusive).

Parameters:

gradient - the array for storing the color gradient

start - the starting color

first - the index in gradient for the start color

end - the end color

last - the index in gradient for the end color

interpolateColors

public void interpolateColors(T[] gradient,
 Color[] colors)

Utility method for creating a smooth gradient spanning all colors in the array colors. An equal number of shades are created between two adjacent colors. The color gradient is stored in the array gradient.

Parameters:

gradient - the array for storing the color gradient

colors - the array of colors for the gradient

translate

public T translate(double data)

Translate the double value data to a color gradient. The type of object returned depends on the implementation.

Parameters:

data - the double value to convert to a color

Returns:

the color object
