PDF::Builder::Outline - Manage PDF outlines (a.k.a. bookmarks)

new
           $outline = PDF::Builder::Outline->new($api, $parent, $prev)

           Returns a new outline object (called from $outlines->outline()).

   ExaminetheOutlineTreehas_children

           $boolean = $outline->has_children()

           Return true if the current outline item has children (child items).

       count

           $integer = $outline->count()

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

       first

           $child = $outline->first()

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

       last

           $child = $outline->last()

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

       parent

           $parent = $outline->parent()

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

       prev

           $sibling = $outline->prev()

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

       next

           $sibling = $outline->next()

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

   ModifytheOutlineTreeoutline

           $child_outline = $parent_outline->outline()

           Returns a new sub-outline (nested outline) added at the end of the current outline's children.

       insert_after

           $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

           $boolean = $outline->is_open() # Get

           $outline = $outline->is_open($boolean) # Set

           Get/set whether the outline is expanded (open) or collapsed (closed).

       open

           $outline->open()

           Set the status of the outline to open (i.e., expanded).

           This is an alternate method to using is_open(true).

       closed

           $outline->closed()

           Set the status of the outline to closed (i.e., collapsed).

           This is an alternate method to using is_open(false).

   SetOutlineAttributestitle

           $title = $outline->title() # Get

           $outline = $outline->title($text) # Set

           Get/set the title of the outline item.

       dest

           $outline->dest($page_object, %position)

           $outline->dest($page_object)

           Sets the destination page and optional position of the outline.

           %position can be any of those listed in "Page Fit Options" in PDF::Builder::Docs.

           "xyz" is the default fit setting, with position (left and top) and zoom the same as the calling
           page's.

               $outline->dest($name, %position)

               $outline->dest($name)

           Connect the Outline to a "Named Destination" defined elsewhere, and optional positioning as described
           above.

   Destinationtargetsuri,url

           $outline->uri($url)

           Defines the outline as launch-url with url $url, typically a web page.

           Alternatename: "url"

           Either "uri" or "url" may be used; "uri" is for compatibility with PDF::API2.

       launch,file

           $outline->launch($file)

           Defines the outline as launch-file with filepath $file. This is typically a local application or
           file.

           Alternatename: "file"

           Either "launch" or "file" may be used; "launch" is for compatibility with PDF::API2.

       pdf,pdf_file,pdfile

           $outline->pdf($pdffile, $page_number, %position, %args)

           $outline->pdf($pdffile, $page_number)

           Defines the destination of the outline as a PDF-file with filepath $pdffile, on page $pagenum
           (default 0), and position %position (same as dest()).

           Alternatenames: "pdf_file" and "pdfile"

           Either "pdf" or "pdf_file" (or the older "pdfile") may be used; "pdf" is for compatibility with
           PDF::API2.
