public final class Type2Function
extends Function<PdfDictionary>

Exponential interpolation of one input value and n output values [PDF:1.6:3.9.2].

Each input value x will return n values, given by y[j] = C0[j] + x^N × (C1[j] − C0[j]), for 0 ≤ j < n, where C0 and C1 are the function results when, respectively, x = 0 and x = 1, and N is the interpolation exponent.
