推荐答案

在此页面上尝试示例: http://www.php.net/manual/zh/imagick.coalesceimages.php

Try the example on this page: http://www.php.net/manual/en/imagick.coalesceimages.php

取决于gif的创建方式，您可能需要合并.也不是关于版本问题的评论.

Depending on how the gif was created you may need the Coalesce; also not the coment about version problems.
