Create thumbnail of PDF or PPT file using php

Question

I want to make thumbnails of pdf or ppt being uploaded by the user I tried

$file = 'Digital Signage.pptx';    
$cache = $_SERVER['DOCUMENT_ROOT'].'/cache/';    
$ext = "jpg";//just the extension    
$dest = $cache.$file.'.'.$ext;    
if (file_exists($dest)){
    $img = new imagick();
    $img->readImage($dest);
    header( "Content-Type: image/jpg" );
    echo $img;
    exit;    
 } else {    
    $img = new imagick($_SERVER['DOCUMENT_ROOT'].'/'.$file.'[0]');
    $img->setImageFormat($ext);    
    $width = $img->getImageheight();
    //$img->cropImage($width, $width, 0, 0);
    $img->scaleImage(105, 149, true);    
    $img->writeImage($dest);    
    header( "Content-Type: image/jpg" );
    echo $img;
    exit;
}

Bu this needs imagic to be intalled on server and my host does not allow me as I am on shared hosting is there any other method to do this

I can use exec command also because it is not secure and I am bound not to use this

Answer 1

I know I am too late to answer this question but, this may help some one else.

There is no way to do the above mentioned task except to use imagick or ghost script(a command line tool), so finally I found a way too enable the imagick extension on another dedicated server and generated images over there and then downloaded them on the server where my site was being hosted file_get_content()
