PDF Clown：リストの作成

Question

JavaでPDF Clownを使用してプログラムでPDFファイルを作成したいと考えています。私は箇条書きでリストを使う必要があります。これはPDF Clownの現在の安定版を使用して可能ですか？もしそうなら、私はAPIドキュメンテーションでどのクラスを調べるべきですか？私はドキュメントのリストを検索していますが、それについての言及はありません。

私が特定のサポートなしでこれを行うと考えることができる唯一の方法は、Xオフセットを持つBlockComposerを使用することですが、これはBulletポイントを持たないでしょう。どんな解決策ですか？

この機能は、PDF Clown（0.2.0）の次期リリースに向けて計画されていますが、それを待つのは遠すぎます。

Answer 1

あなたは、これが、これがまだ安定していない、新しい0.2.0作曲を使用しています。この

    to CSS styles defined through an element type selector).
