For PDFs this function indicates the number of pages on the PDF, NOT images that might be embedded within the PDF.



<?php



$document = new Imagick('2_pager.pdf');



var_dump($document->getNumberImages()); //returns 2



$document = new Imagick('1_pager.pdf');



var_dump($document->getNumberImages()); //returns 1



?>



From my research it is not possible to obtain the images embedded within a PDF by using the PHP Imagick library.
