添加PDF的页眉和页脚

Aspose.PDF for .NET 使您能够向现有的 PDF 文件添加页眉和页脚。您可以将图像和文本插入文档中。

以下代码片段也适用于 Aspose.PDF.Drawing 库。

将页眉和页脚添加为文本片段

以下代码片段演示了如何使用 C# 将页眉和页脚作为文本片段添加到 PDF 中。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddHeaderAndFooterAsText()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_HeaderFooter();
  
    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "AddHeaderAndFooterAsTextInput.pdf"))
    {
        for (var i = 1; i <= document.Pages.Count; i++)
        {
            // Create header text
            var headerText = new Aspose.Pdf.Text.TextFragment("header");
            
            // Create header
            var header = new Aspose.Pdf.HeaderFooter();
            header.Paragraphs.Add(headerText);
