Class Gradient

All Implemented Interfaces:
Colormap, Serializable, Cloneable

public class Gradient extends ArrayColormap implements Cloneable, Serializable
A Colormap implemented using Catmull-Rom colour splines. The map has a variable number of knots with a minimum of four. The first and last knots give the tangent at the end of the spline, and colours are interpolated from the second to the second-last knots. Each knot can be given a type of interpolation. These are:
  • LINEAR - linear interpolation to next knot
  • SPLINE - spline interpolation to next knot
  • CONSTANT - no interpolation - the colour is constant to the next knot
  • HUE_CW - interpolation of hue clockwise to next knot
  • HUE_CCW - interpolation of hue counter-clockwise to next knot
