insert_before

$sibling = $outline−>insert_before();

Launch an application or file when the outline item is activated.

pdf

$outline = $outline−>pdf($filename, $page_number, $location, @args);

Open another PDF file to a particular page number (first page is zero, which is also the default). The page can optionally be positioned at a particular location if $location and @args are set −− see "destination" in PDF::API2::NamedDestination for possible settings.
