NAME

       PDF::API2::Outline - Manage PDF outlines (a.k.a. bookmarks)

METHODS

       $outline = PDF::API2::Outline->new($api, $parent, $prev)
           Returns a new outline object (called from $outlines->outline()).

       $outline->title($text)
           Set the title of the outline.

       $outline->closed()
           Set the status of the outline to closed (i.e. collapsed).

       $outline->open()
           Set the status of the outline to open (i.e. expanded).

       $child_outline = $parent_outline->outline()
           Returns a nested outline.

       $outline->dest($page_object, %position)
           Sets the destination page and optional position of the outline.

           %position can be any of the following:

           -fit => 1
               Display the page designated by page, with its contents magnified just enough to
               fit the entire page within the window both horizontally and vertically. If the
               required horizontal and vertical magnification factors are different, use the
               smaller of the two, centering the page within the window in the other dimension.

           -fith => $top
               Display the page designated by page, with the vertical coordinate $top positioned
               at the top edge of the window and the contents of the page magnified just enough
               to fit the entire width of the page within the window.

           -fitv => $left
               Display the page designated by page, with the horizontal coordinate $left
               positioned at the left edge of the window and the contents of the page magnified
               just enough to fit the entire height of the page within the window.

           -fitr => [$left, $bottom, $right, $top]
               Display the page designated by page, with its contents magnified just enough to
               fit the rectangle specified by the coordinates $left, $bottom, $right, and $top
               entirely within the window both horizontally and vertically. If the required
               horizontal and vertical magnification factors are different, use the smaller of
               the two, centering the rectangle within the window in the other dimension.

           -fitb => 1
               Display the page designated by page, with its contents magnified just enough to
               fit its bounding box entirely within the window both horizontally and vertically.
               If the required horizontal and vertical magnification factors are different, use
               the smaller of the two, centering the bounding box within the window in the other
               dimension.

           -fitbh => $top
               Display the page designated by page, with the vertical coordinate $top positioned
               at the top edge of the window and the contents of the page magnified just enough
               to fit the entire width of its bounding box within the window.

           -fitbv => $left
               Display the page designated by page, with the horizontal coordinate $left
               positioned at the left edge of the window and the contents of the page magnified
               just enough to fit the entire height of its bounding box within the window.

           -xyz => [$left, $top, $zoom]
               Display the page designated by page, with the coordinates ($left, $top) positioned
               at the top-left corner of the window and the contents of the page magnified by the
               factor $zoom. A zero (0) value for any of the parameters $left, $top, or $zoom
               specifies that the current value of that parameter is to be retained unchanged.

       $outline->dest($name)
           Connect the outline to a "Named Destination" defined elsewhere.

       $outline->url($url)
           Launch $url when the outline item is activated.

       $outline->file($filename)
           Launch an application or file when the outline item is activated

       $outline->pdf_file($filename, $page_number, %position)
           Open a 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 place in the viewport
           (see dest for details).
