==================================
The `ocgx2' LaTeX Package
Version 0.7 [2015/07/20]
(C) 2015--\today Alexander Grahn
==================================
1. Introduction
===============
The intent of this package is to be a drop-in replacement for the already
existing package `ocgx' by Paul Gaborit.
It re-implements the functionality of the `ocg', `ocgx' and `ocg-p' packages
and adds support for all known engines and back-ends including:
* LaTeX --> dvips --> ps2pdf/Distiller
* (Xe)LaTeX --> (x)dvipdfmx
* pdfLaTeX, luaLaTeX
To enable dvipdfmx support, pass `dvipdfmx' globally as a class option.
Also, it adds some minor improvements, such as package options,
remembering option settings of re-opened ocgs, correct behaviour of ocg
switching links that were themselves placed on layers, compatibility
with the `animate' and `media9' packages.
`ocgx2' uses code from file `tikzlibraryocgx.code.tex' by P. Gaborit to
enable TikZ styles for creating PDF Layers and clickable layer switching
links in the `tikzpicture' context.
Just say:
\usepackage[tikz]{ocgx2}
instead of
\usepackage{tikz}
\usetikzlibrary{ocgx}
to enable these TikZ styles and read the `ocgx' documentation about their usage:
texdoc ocgx
2. Usage
========
\usepackage[<options>]{ocgx2}
\begin{ocg}[<options>]{<layer name>}{<layer id>}{<initial visibility>}
... material to be put on a PDF layer ...
\end{ocg}
With <options> : viewocg = always | never | ifvisible
printocg = always | never | ifvisible
exportocg = always | never | ifvisible
listintoolbar= always | never | iffirstuse
tikz (package-only option, see above)
Package options have global scope. Environment options override package
options locally. `ocg' environments can be nested.
See the `ocg-p' manual about the environment usage and the meaning of
the available options:
texdoc ocg-p
Clickable links for switching PDF layer visibility are created with:
\switchocg{<layer IDs to toggle, space separated>}{<link text>}
\showocg{<layer IDs to switch ON, space separated>}{<link text>}
\hideocg{<layer IDs to switch OFF, space separated>}{<link text>}
\actionsocg{<IDs to toggle>}{<IDs to switch ON>}{<IDs to switch OFF>}{<link text>}
For details about their usage, read the `ocgx' package manual:
texdoc ocgx
For compatibility with the `ocg-p' package, the following aliases for
the above commands have been provided:
\toggleocgs
\showocgs
\hideocgs
\setocgs
