png_compression_level 选项应该是 0 到 9 之间的整数

Question

我使用的是 Symfony 2.3.*，当我使用 LiipImagineBundle 时，我在 app/logs/dev.log 中收到此错误。

request.CRITICAL: Uncaught PHP Exception Imagine\Exception\InvalidArgumentException: "png_compression_level option should be an integer from 0 to 9" at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php line 535 {"exception":"[object] (Imagine\\Exception\\InvalidArgumentException: png_compression_level option should be an integer from 0 to 9 at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php:535)"} []

有什么解决办法吗？谢谢

这是我的配置

liip_imagine:
    resolvers:
       default:
          web_path: ~
    filter_sets:
        cache: ~
        standard:
            quality: 200
            filters:
                thumbnail: { size: [400, 300], mode: outbound }

如果您使用 SonataMediaBundle，请检查它quality是否不超过 100。
