2 年後、MigraDoc と PDFsharp でいくつかのことをするために戻ってきました。生活を楽にするために、スタイルのヘルパー関数を作成しましたが、なぜこれが期待どおりに機能しないのだろうか?
フォントの割り当てはすべて問題なく機能します。フォント ファミリー、サイズ、タイプ、および色が正しく表示されます。また、リンクが作成され、それらも機能します。
ただし、段落スタイルはすべて無視されます。デバッガーで確認できるように、それらは新しいスタイルに割り当てられていますが、レンダリングされていません。
段落や節のルールなのかもしれませんが、私にはわかりません。
誰かが私を啓発できますか？
