@PDF(value=PDF12)
public final class Type0Function
extends Function<PdfStream>

Sampled function using a sequence of sample values to provide an approximation for functions whose domains and ranges are bounded [PDF:1.6:3.9.1].

The samples are organized as an m-dimensional table in which each entry has n components.
