This class represents the jbig2 parameters. This is definitively detailed in:.

The ISO PDF Specification, ISO 32000-1:2008 PDF 1.7; Table: 12, page 32.

The ISO PDF Specification, ISO 32000-2:2017 PDF 2.0; Table: 12, page 46.

The JBIG2 decode parameters dictionary configures the JBIG2Decode filter, which implements the JBIG2 standard for lossless and lossy compression of bi-level images.

JBIG2 can achieve significantly better compression than CCITT Group 4 for text and halftone images by using symbol dictionaries that allow repeated glyphs to be encoded by reference rather than by value.

The JBIG2Globals entry references a stream containing global segments that are shared across multiple JBIG2 streams in the document. Using a global segment avoids repeating the symbol dictionary in every page stream.
