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:

egin{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.
