特定のページにヘッダー/フッターを追加

IronPDF には、既存の PDF ファイルにヘッダーとフッターを追加する機能があります。

また、IronPDF のメソッドを使用して、古いまたは新しいPDFドキュメントにカスタマイズされた Headers および Footers を追加することもできます。これを行うには、次の方法を使用して PDF がレンダリングされるまで待機します。

− IronPDFを用いたテキストヘッダーの追加はIronPdf.PdfDocument.AddHeaders(IronPdf.TextHeaderFooter, System.Boolean, System.Collections.Generic.IEnumerable<System.Int32>)を使用します − IronPDFを用いたテキストフッターの追加はIronPdf.PdfDocument.AddFooters(IronPdf.TextHeaderFooter, System.Boolean, System.Collections.Generic.IEnumerable<System.Int32>)を使用します − IronPDFを用いたHTMLヘッダーの追加はIronPdf.PdfDocument.AddHTMLHeaders(IronPdf.HtmlHeaderFooter, System.Boolean, System.Collections.Generic.IEnumerable<System.Int32>)を使用します − IronPDFを用いたHTMLフッターの追加はIronPdf.PdfDocument.AddHTMLFooters(IronPdf.HtmlHeaderFooter, System.Boolean, System.Collections.Generic.IEnumerable<System.Int32>)を使用します
