Domain

(Required) A collection of mPdfNumberRanges, where m shall be the number of input values. For each i from 0 to m − 1, Domain[i].First shall be less than or equal to Domain[i].Last, and the ith input value, x[i], shall lie in the interval Domain[i].First ≤ x[i] ≤ Domain[i].Last. Input values outside the declared domain shall be clipped to the nearest boundary value.

Metadata

(Optional; PDF 1.4) A metadata stream containing metadata for the component.

(Inherited from PdfObject)

Range

(Required for PdfSampledFunctions and PdfPostScriptCalculatorFunctions, optional otherwise) A collection of nPdfNumberRanges, where n shall be the number of output values. For each j from 0 to n − 1, Range[j].First shall be less than or equal to Range[j].Last, and the jth output value, y[j] , shall lie in the interval Range[j].First ≤ y[j] ≤ Range[j].Last. Output values outside the declared range shall be clipped to the nearest boundary value. If this entry is absent, no clipping shall be done.
