NAME

PDF::API2::Basic::PDF::Pages - Low-level page tree object

DESCRIPTION

A Pages object is the parent to other pages objects or to page objects themselves.

METHODS

PDF::API2::Basic::PDF::Pages->new($pdf, $parent)

This creates a new Pages object in a PDF. Notice that $parent here is not the file context for the object but the parent pages object for this pages. If we are using this class to create a root node, then $parent should point to the file context, which is identified by not having a Type of Pages. $pdf is the file object (or a reference to an array of file objects) in which to create the new Pages object.

$p->find_page($page_number)

Returns the given page, using the page count values in the pages tree. Pages start at 0.

$p->add_page($page, $page_number)

Inserts the page before the given $page_number. $page_number can be negative to count from the END of the document. -1 is after the last page. Likewise $page_number can be greater than the number of pages currently in the document, to append.

@objects = $p->get_pages()

Returns a list of page objects in the document in page order

$p->find_prop($key)

Searches up through the inheritance tree to find a property.

$p->add_font($pdf, $font)

Creates or edits the resource dictionary at this level in the hierarchy. If the font is already supported even through the hierarchy, then it is not added.

$p->bbox($xmin, $ymin, $xmax, $ymax, [$param])

Specifies the bounding box for this and all child pages. If the values are identical to those inherited then no change is made. $param specifies the attribute name so that other 'bounding box'es can be set with this method.

$p->proc_set(@entries)

Ensures that the current resource contains all the entries in the proc_sets listed. If necessary it creates a local resource dictionary to achieve this.

$p->get_top

Returns the top of the pages tree
