It seems that dompdf doesn't support it (and may take a while to do it): http://groups.google.com/group/dompdf/browse_thread/thread/d0560edc58ed6...

I would advise that you try wkhtmltopdf.

For users of dompdf, creating a copy instead of a clone in lib/class.pdf.php line 4971 should fix this:

//$alpha_channel = clone $imagick;
$alpha_channel = new Imagick($file);
$alpha_channel->setFormat('png');

Please report this in the dompdf issue queue (http://code.google.com/p/dompdf/issues/list), not here. I can't fix dompdf.
