Cakephp和imagick -原始文件不需要上传

上传JPEG时一切正常。但是，当上传RAW时，它确实有效。我有php.ini上传限制设置为25M。我可以上传7MB的JPEG文件，但不能上传7MB的RAW文件。下面是我收到的错误:

下面是第264行代码:

$this->data['PhotoBankImage']['width'] = $this->image->getImageWidth();

以下是我认为相关的php.ini设置:

post_max_size = 25M
post_max_size = 25M
memory_limit = 512M
max_execution_time = 120
max_input_time = 120

我非常感谢任何帮助，如果您还需要我做什么，请告诉我，以便更好地理解问题。
