CTAN Update: ocgx
The ocgx package extends the ocg-p package (previous version extended the ocg package), which allows you to create OCGs (Optional Content Groups) in PDF documents.
This package is located at http://mirror.ctan.org/macros/latex/contrib/ocgx . More information is at http://www.ctan.org/pkg/ocgx (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org . Please join a users group; see http://www.tug.org/usergroups.html .
Thanks for the upload. For the CTAN Team Rainer Schöpf
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.
