PDF document page abstraction is represented by
PDF pages either are loaded from existing PDF, or created.
New page can be obtained by creating new

The difference is that

It's an array of
Zend_Pdf_Page objects. It completely defines set and order of document pages
and can be manipulated as a common array:

<?php ... // Reverse page order $pdf->pages = array_reverse($pdf->pages); ... // Add new page $pdf->pages = new Zend_Pad_Page(Zend_Pdf_Const::PAGESIZE_A4); // Add new page $pdf->pages = $pdf->newPage(Zend_Pdf_Const::PAGESIZE_A4); // Remove specified page. unset($pdf->pages[$id]); ... ?>
 It's a limitation of V1.0 version of Zend_Pdf module. It will be eliminated in future versions. But unattached pages will always give better (more optimal) result for sharing pages between documents.
