All Known Implementing Classes:

ImageMappingImpl

public interface ImageMapping
extends Element

This class defines how to transform a number array to a pseudo-color or grayscale image. The transformation take these steps:

1. Apply limit algorithm
2. Apply intensity transform
3. Apply bias/gain. method of Schlick(C. Schlick, Fast Alternatives to Perlin's Bias and Gain Functions)
4. zoom to correct size for display
5. Apply color map to produce a pseudo-color image
