As explained at the above link, the following script consistently segfaults if this image is saved in the same directory and named original.png. If the image data is retrieved via getImageBlob, duplicate.png is a proper copy of original.png; otherwise, it is empty. The test case is to be run via php -f test.php:
Code: Select all
<?php
$thumb = new Imagick('original.png');
$thumb->setImageFormat('png');
//echo $thumb->getImageBlob();
$thumb->writeImage('duplicate.png');
?>
