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.
