Examples of ar.Transfer

ar.Transfer
Transfer functions converts an aggregate value into another aggregate value, often a color. Transfer functions are doing analysis and transformation on the discrete values represented by a set of aggregates. Since Abstract Rendering is focused on visualization, many transfer functions directly produce colors (and an image is essentially a set of color aggregates). However, sometimes producing colors immediately is awkward, so transfer functions are generalized to produce any time of aggregate desired. Multi-stage transfer is logically the same as single stage, by simple function composition. ar.util.combinators.Chain is a utility for achieving that composition. Transfer functions have a two-phase life cycle: generic and specialized. Often a transfer function needs information about the data it is about to process before it can process the first pixel (such as the bounds on the values). Generic transfers don't know this information yet, specialized ones do. The "Specialize" method converts a generic function into a specialized one OR a specialized one into another one (specialized transfer functions retain the capabilities of generic ones). The Transfer.Specialized interface indicates that a transfer function is ready for use. TODO: Has Specialized-is-transfer-too outlived its usefulness? I don't know that it is ever used....
