fpdf and bmp

Hi all,
I must display some images in a pdf report.
I’m using the sc_pdf_image command in the code section:

$finfo = finfo_open(FILEINFO_MIME_TYPE);
$t= finfo_file($finfo, $nomefileatt);
$t = strtoupper(substr(strrchr($t,"/"),1));
sc_pdf_image($nomefile,10,$y,$width,$height,$t);}

But it seems the fpdf library doesn’t support bmp files.
How can make it works with bmp ?
I found an extension to add bmp support to fpdf library (http://www.fpdf.de/downloads/addons/1000093/) but i don’t know how to make it works with sc.

Thanks
