Constructors

PdfType3Function(double[], double[], IList<AbstractPdfFunction<PdfDictionary>>, double[], double[])

public PdfType3Function(double[] domain, double[] range, IList<AbstractPdfFunction<PdfDictionary>> functions, double[] bounds, double[] encode)

Parameters

domain double[]

the valid input domain, input will be clipped to this domain contains a min max pair per input component

range double[]

the valid output range, oputput will be clipped to this range contains a min max pair per output component

functions IList<AbstractPdfFunction<PdfDictionary>>

The list of functions to stitch

bounds double[]

(Required) An array of k − 1 numbers that, in combination with Domain, shall define the intervals to which each function from the Functions array shall apply. Bounds elements shall be in order of increasing value, and each value shall be within the domain defined by Domain.

encode double[]

(Required) An array of 2 × k numbers that, taken in pairs, shall map each subset of the domain defined by Domain and the Bounds array to the domain of the corresponding function.

PdfType3Function(float[], float[], IList<AbstractPdfFunction<PdfDictionary>>, float[], float[])

(see ISO-320001 Table 41).
