Add an outline item immediately following the current item.

insert_before

$sibling = $outline->insert_before();

Add an outline item immediately preceding the current item.

delete

$outline->delete();

Remove the current outline item from the outline tree. If the item has any children, they will effectively be deleted as well since they will no longer be linked.

is_open

# Get
my $boolean = $outline->is_open();
# Set
my $outline = $outline->is_open($boolean);

Get/set whether the outline is expanded or collapsed.

Set Outline Attributes

# Get
my $title = $outline->title();
# Set
$outline = $outline->title($text);

Get/set the title of the outline item.

destination

$outline = $outline->destination($destination, $location, @args);

$destination can optionally be the name of a named destination defined elsewhere.

$outline = $outline->uri($uri);

Launch a URI -- typically a web page -- 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.
