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();

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