Paste a PDF-file into another PDF with ZendPDF

Question

Is it possible to "merge" or "paste" a PDF-file into antother PDF? Or must it be a image instead?

The PDF i want to to paste or merge, is a simple picture that is going to appear at the bottom of the finished PDF:

//Generate the "Original" PDF here..

function addReklam($reklamblad) //The PDF that should be merged into the PDF that is created above
    {

     //Count how many pages that has been created, and add it at the bottom of the PDF:

        if($this->drawed_lines<52)
        {
            $this->active_page = $this->pdf->pages[2];
        }
        elseif($this->drawed_lines<92)
        {
            $this->active_page = $this->pdf->pages[3];
        }
        elseif($this->drawed_lines<132)
        {
            $this->active_page = $this->pdf->pages[4];
        }
        else
        {
            $this->active_page = $this->pdf->pages[5];
        }
        //$this->active_page = $this->pdf->pages[5];        // page 5 is the last
           //Add it here???         

    }

My recommendation would be to use the Zend_Pdf::load() method to load the "Original" PDF file into a local instance of Zend_Pdf and then you can access the pages using the pages[] array as in your sample code and use the all the standard functions like drawImage() etc to make the needed modifications prior to saving the updated version.
