Users looking to save with these functions should know it can be done easily, for example
<?php
header ("Content-Type: image/{$Imagick->getImageFormat()}");
$data = $Imagick->getImageBlob ();
echo $data;
file_put_contents ('test.png', $data);
?>
That would display the image, and then save it to test.png. Such things are helpful especially when you need to reload images after creating them or save for later. :)
