public class ColorMap
extends PicPipe
This pipeline gets a double and returns a color based on linear interpolation. The color map comprises multiple assignments of colors to real values, and this program does linear interpolation between the colors to convert doubles to colors. If the value exactly matches one or more of the doubles, it takes the first one. The entries should be sorted with increasing real values.
