Imagick::getNumberImages — Retorna o número de imagens no objeto
Retorna o número de imagens associadas ao objeto Imagick.
Esta função não possui parâmetros.
Retorna o número de imagens associadas ao objeto Imagick.
Lança uma exceção ImagickException em caso de erro.
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.<?php
/* Create the object */
$image = new Imagick('YourImageLocation.tif');
$count = $image->getNumberImages();
echo "<h3 style=\"font: bold 12pt Arial\">Total Number of Images Extracted ".
"from the TIF : ".$image->getNumberImages()."</h3>";
for ($x = 1;$x <= $image->getNumberImages(); $x++) {
$image->previousImage();
$image->thumbnailImage( 400, null );
$image->writeImage('img'.$count.'.png');
$count--;
}
?>
