Technically your requirements could be done by transforming the page into a so called form XObject which can be place on a new created page. That's how FPDI works: http://www.setasign.com/products/fpdi/demos/thumbnails/ (maybee an alternative for you).
I just checked the code of ZendPdf but I cannot find any method that may allow this.
Rotation can be done with FPDF/FPDI too: http://fpdf.org/en/script/script2.php
