/**
 * {@link ColorMapTransformElement}s are a special type of {@link PiecewiseTransform1DElement}s that can be used to generate specific renderings as

 * 
 * <p>
 * A popular example is represented by a {@link DomainElement1D} used to classify values which means applying a color to all the pixels of an image
 * whose value falls in the {@link DomainElement1D}'s range.
