public Function(List<Double> domain, List<Double> range, float[] cZero, float[] cOne, double interpolationExponentN)
domain
- List objects of Double objects.
This is the domain of the function.
See page 264 of the PDF 1.3 Spec.range
- List of Doubles that is the Range of the function.
See page 264 of the PDF 1.3 Spec.cZero
- This is a vector of Double objects which defines the function result
when x=0.
This attribute is optional.
It's described on page 268 of the PDF 1.3 spec.cOne
- This is a vector of Double objects which defines the function result
when x=1.
This attribute is optional.
It's described on page 268 of the PDF 1.3 spec.interpolationExponentN
- This is the inerpolation exponent.
This attribute is required.

domain
- List objects of Double objects.
This is the domain of the function.
See page 264 of the PDF 1.3 Spec.range
- List objects of Double objects.
This is the Range of the function.
See page 264 of the PDF 1.3 Spec.functions
- A List of the PDFFunction objects that the stitching function stitches.
This attributed is required.
It is described on page 269 of the PDF spec.bounds
- This is a vector of Doubles representing the numbers that,
in conjunction with Domain define the intervals to which each function from
the 'functions' object applies. It must be in order of increasing magnitude,
and each must be within Domain.
It basically sets how much of the gradient each function handles.
This attributed is required.
It's described on page 269 of the PDF 1.3 spec.encode
- List objects of Double objects.
This is the linear mapping of input values intop the domain
of the function's sample table. Default is hard to represent in
ascii, but basically [0 (Size0 1) 0 (Size1 1)...].
This attribute is required.
