PDF を画像に変換

構成

手順

1. Imagemagick がインストールされているか確認

  • sudo dpkg -l
  • pkg-config --cflags --libs MagickWand
    • 曰く

    • Check if pkg-config is able to find the right ImageMagick include and libs

2. 環境変数 CGO_CFLAGS_ALLOW を設定

なんか必要っぽい

3. ImageMagick-6 のポリシーを書き換える

脆弱性対策のために PDF の変換を許可しないポリシーが書いてあるので、コメントアウトする。

<!-- /etc/ImageMagick-6/policy.xml -->
<policymap>
  ...
  <policy domain="coder" rights="none" pattern="PDF" />
</policymap>

終わったら戻す。まぁローカルなら問題ないだろうけど。
