Where is the oposite of imagecreatefromstring
<p>I have an image in a string <code>$data</code>. I need to resize that image, so I convert it to a <code>image</code> with <code>imagecreatefromstring</code>. How to I get that resized image back to <code>$data</code> variable? All I've found is <code>imagepng</code> in its ilk.</p>
