## Description

A structure used to store data related to layers in a PDF.

The Optional Content Configuration Structure is used to maintain a set of visibility states and other optional values related to layers, or Optional Content Groups, within a PDF file.

These configuration values are stored for future use.

The default configuration for a PDF document is stored in the D entry in the Optional Content Properties dictionary.

An Optional Content Group, or layer, is a set of graphic images that can be made visible or invisible within a PDF file, and the Optional Content Configuration Structure is typically used to set the initial value for these images-On or Off, visible or invisible.
