The package extends the ocg package, which allows you to create OCGs (Optional Content Groups) in PDF documents. (The ocg package is distributed as part of Asymptote.)

Every OCG includes TeX material into a layer of the PDF file. Each of these layers can be displayed or not. Links can enable or disable the display of OCGs.

The ocgx package does not use Javascript embedded in the PDF document to enable (to show) or disable (to hide) OCGs.
