com.inductiveautomation.rm.pdf.reader.fps.SampledFunction

public class SampledFunction
extends PDFFunction

Type 0 sampled functions. The original function is sampled at various points and these values are passed as a pdf stream. When a sampledFunction is evaluated, it looks in the sample table for the values corresponding to the sampled points surrounding the input value and interpolates between them. Functions of Order 0 use multilinear interpolation, while Order 3 functions use a cubic spline.
