## Package org.pdfclown.documents.functions Description

Static, self-contained numerical transformations that represent parameterized classes of functions, including mathematical formulas and sampled representations with arbitrary resolution [PDF:1.6:3.9].

Functions are used in various ways in PDF, including device-dependent rasterization information for high-quality printing (halftone spot functions and transfer functions), color transform functions for certain color spaces, and specification of colors as a function of position for smooth shadings.
