SYNOPSIS

           # Get/create the top-level outline tree
           my $outline = $pdf->outline();

           # Add an entry
           my $item = $outline->outline();
           $item->title('First Page');
           $item->destination($pdf->open_page(1));

METHODS

   Examine the Outline Tree
       has_children

           my $boolean = $outline->has_children();

       Return true if the current outline item has child items.

       count

           my $integer = $outline->count();

       Return the number of descendants that are visible when the current outline item is open
       (expanded).

       first

           my $child = $outline->first();

       Return the first child of the current outline level, if one exists.

       last

           my $child = $outline->last();

       Return the last child of the current outline level, if one exists.

       parent

           my $parent = $outline->parent();

       Return the parent of the current item, if not at the top level of the outline tree.

       prev

           my $sibling = $outline->prev();

       Return the previous item of the current level of the outline tree.

       next

           my $sibling = $outline->next();

       Return the next item of the current level of the outline tree.

   Modify the Outline Tree
       outline

           my $child = $outline->outline();

       Add an outline item at the end of the current outline's list of children.

       insert_after

           my $sibling = $outline->insert_after();

       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
       title

           # 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);

       Set the destination page and optional position of the outline.  $location and @args are as
       defined in "destination" in PDF::API2::NamedDestination.

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

       uri

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

       Launch a URI -- typically a web page -- when the outline item is activated.

       launch

           $outline->launch($file);

       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.
