Represents the "HalftoneName" entry of the type 5 halftone dictionary object.

It is an optional entry defined as part of the PDF 1.0 specification.

It contains a string representing a PDF string object.

This string contains raw byte data. So it looks like a string but really it is just a wrapper for data.

For definitive details see:.

The ISO PDF Specification, ISO 32000-1:2008 PDF 1.7; Table: 134, page 315.

The ISO PDF Specification, ISO 32000-2:2017 PDF 2.0; Table: 132, page 377.

Like all HalftoneName values, this is raw byte data rather than a text string. It names the composite halftone as a whole rather than any individual colorant screen.

Each sub-dictionary in the type 5 structure may carry its own HalftoneName identifying that particular colorant screen separately from the composite name.
