Hey Patrice thanks for your quick reply ,
I'm trying to use dynamic image feature using PHP app engine according to the official documentation in order to use this feature I have to use CloudStorageTools . as declared in the following code
require_once 'google/appengine/api/cloud_storage/CloudStorageTools.php';
use google\appengine\api\cloud_storage\CloudStorageTools;
$object_image_file = 'gs://my-bucket/myfile.png';
$object_image_url = CloudStorageTools::getImageServingUrl($object_image_file,
['size' => 400, 'crop' => true]);
header('Location:' .$object_image_url);
the problem that I can't find CloudStorageTools Class in Google PHP client library .
I have a doubt that CloudStorageTools is a part of Google cloud storage and I have to integrate both Google cloud storage and Google app engine together in order to do the above code I could be mistaken .
Thanks ,
