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

# Get/create the top-level outline tree
my $outlines = $pdf->outline();
# Add an entry
my $item = $outlines->outline();
$item->title('First Page');
$item->dest($pdf->open_page(1), fit-def);

$outline = PDF::Builder::Outline->new($api, $parent, $prev)
Returns a new outline object (called from $outlines->outline()).

has_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.

outline

$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).

title

$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.

uri, url

$outline->uri($url)
Defines the outline as launch-url with url $url, typically a web page.

Alternate name: "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.

Alternate name: "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()).

Alternate names: "pdf_file" and "pdfile"

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