- com.jhlabs.image.ArrayColormap
- - com.jhlabs.image.SplineColormap

All Implemented Interfaces:

Colormap, java.lang.Cloneable
```
public class SplineColormap
extends ArrayColormap
```
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.
