The second parameter will update the result of getFilename() if set. Otherwise the result of getFilename() will retain its original value, prior to calling readImageFile().

An example of reading an image file from a URL, using a handle returned by fopen():



<?php

$handle = fopen('http://example.com/foo.jpg', 'rb');

$img = new Imagick();

$img->readImageFile($handle);

$img->resizeImage(128, 128, 0, 0);

$img->writeImage('images/foo.jpg');

?>
