java.lang.Objectorg.apache.fop.pdf.PDFObject
org.apache.fop.pdf.PDFPathPaint
org.apache.fop.pdf.PDFPattern
class representing a PDF Function. PDF Functions represent parameterized mathematical formulas and sampled representations with arbitrary resolution. Functions are used in two areas: device-dependent rasterization information for halftoning and transfer functions, and color specification for smooth shading (a PDF 1.3 feature). All PDF Functions have a FunctionType (0,2,3, or 4), a Domain, and a Range.
