When reading a PDF from an ImageBlob, and you want to set the page to be used, this is the function to use.

when you read pdf by getImageBlog and want to get the image or blob of a specific page, use this function as below.

$ims = new Imagick();

$ims->readImageBlob($pdfFileContent);

$ims->setImageIndex(5); //this will return 6th page of the pdf file
$image->setImageFormat('png');
//etc
$blob = $image->getImageBlob();
