This class represents the parameter dictionary. This is definitively detailed in:.

The ISO PDF Specification, ISO 32000-1:2008 PDF 1.7; page 22.

Parameter dictionaries carry decode parameters for stream filters. Each filter that requires configuration has a corresponding parameter dictionary type. The parameter dictionary is referenced from the stream's DecodeParms entry.

When a stream uses multiple filters, the DecodeParms entry holds an array with one parameter dictionary per filter in the same order as the Filter array. A null entry in the array means the corresponding filter takes no parameters.
