CI and fpdf/fpdi

[eluser]pendalpusher[/eluser]
Yesterday I got Fpdf and Fpdi working within the CI framework.

Currently to access the classes I am doing this.

Code:

$this->load->library('fpdf');
$this->load->library('fpdi');

//now do something with them
$this->fpdi->AddPage();
$this->fpdi->Output();

My question is how to make multiple instances? Outside of CI i would do it like this

Code:

$pdf1 = new fpdi();


$pdf2 = new fpdi();

Do I need make two seperate models? or what?

Thanks in advance.
