問題如下：

convert-im6.q16: attempt to perform an operation not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/408.

解法如下：

$ sudo vim /etc/ImageMagick-6/policy.xml
    <policy domain="coder" rights="read | write" pattern="PDF" />

P.S. 需要注意ImageMagick-X的版本差異，添加的內容是在</policymap>前一行
