This package provides the \autodoc:command{\rebox} command, which allows you to lie to SILE about the size of content.










27



You can change the \autodoc:parameter{width}, \autodoc:parameter{height}, or \autodoc:parameter{depth} of your content with the respective parameters, or make it invisible by setting the \autodoc:parameter{phantom} parameter to \code{true}.

\begin[type=autodoc:codeblock]{raw}










32



Hello \rebox[width=0pt]{world}overprint.

34



Look I’m not \rebox[phantom=true]{here}!

\end{raw}
