在现有PDF中插入分页符

作为默认布局，PDF文件中的内容是从左上角到右下角添加的。一旦内容超过页面底部边距，就会发生分页符。然而，您可能会遇到根据需求插入分页符的要求。为了满足这一要求，在PdfFileEditor类中添加了一个名为AddPageBreak(…)的方法。

1. public void AddPageBreak(Document src, Document dest, PageBreak[] pageBreaks).
2. public void AddPageBreak(string src, string dest, PageBreak[] pageBreaks).
3. public void AddPageBreak(Stream src, Stream dest, PageBreak[] pageBreaks).

• src是源文档/文档路径/包含源文档的流。
• dest是目标文档/文档将保存的路径/文档将保存的流。
• PageBreak是分页符对象的数组。它有两个属性：分页符必须放置的页面索引和分页符在页面上的垂直位置。

示例 1（添加分页符）

private static void PageBrakeExample01()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_PageBreak();

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "PageBreak.pdf"))
    {
        // Create PDF document
        using (var dest = new Aspose.Pdf.Document())
        {
            // Create PdfFileEditor object
            var fileEditor = new Aspose.Pdf.Facades.PdfFileEditor();
            fileEditor.AddPageBreak(document, dest, new Aspose.Pdf.Facades.PdfFileEditor.PageBreak[]
            {
                new Aspose.Pdf.Facades.PdfFileEditor.PageBreak(1, 450)
            });
            // Save PDF document
            dest.Save(dataDir + "PageBreak_out.pdf");
        }
    }
}
