CTAN Update: ocgx2

[CTAN Announcements]

Alexander Grahn submitted an update to the

                ocgx2

package.

Version:  0.41 2019-05-24
License:  lppl

Summary description:  Drop-in replacement for ‘ocgx’ and ‘ocg-p’

Announcement text:
----------------------------------------------------------------------
 
 This new version adds the `ocmd' environment:

   \begin{ocmd}[<OCMD id>]{[<visibility policy>][,<visibility expression>]}

     ... material to be put on a PDF layer ...

   \end{ocmd}

 An OCMD (Optional Content Membership Dictionary) is a PDF Layer whose
 visibility is calculated from other OCGs current visibility states according
 to a visibility policy and/or a visibility expression.

 A visibility policy is defined by choosing one of the directives

   \AllOn{<OCG id 1>, <OCG id 2>, ...}
   \AnyOn{<OCG id 1>, <OCG id 2>, ...}
   \AnyOff{<OCG id 1>, <OCG id 2>, ...}
   \AllOff{<OCG id 1>, <OCG id 2>, ...}

 A visibility expression is much more flexible than a policy. Arbitrarily
 complex visibility relationships can be formulated, based on the Boolean
 functions

   \And{<item a>, <item b>, ...}
   \Or{<item i>, <item j>, ...}
   \Not{<item n>}

 In the argument list, items represent OCG ids and nested Boolean
 functions. As nesting of the three functions is possible, any thinkable
 visibility relationship can be defined.
