Page Break in existing PDF

As a default layout, the contents inside PDF files are added in Top-Left to Bottom-Right layout. Once the contents exceed beyond page bottom margin, the page break occurs. However you may come across a requirement to insert page break depending upon requirement. A method named AddPageBreak(…) method is added in PdfFileEditor class to accomplish this requirement.)

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 is source document/path to document/stream with source document.
• dest is destination document/path where document will be saved/stream where document will be saved.
• PageBreak is array of page break objects. It have two properties: index of page where page break must be placed and vertical position of the page break on the page.

Example 1 (Add page break)

public static void PageBrakeExample01()
{
    // Instantiate Document instance
    Document document = new Document(dataDir + "Sample-Document-01.pdf");
    // Instantiate blank Document instance
    Document dest = new Document();
    // Create PdfFileEditor object
    PdfFileEditor fileEditor = new PdfFileEditor();
    fileEditor.AddPageBreak(document, dest, new PdfFileEditor.PageBreak[]
    {
        new PdfFileEditor.PageBreak(1, 450)
    });
    // Save resultant file
    dest.Save(dataDir + "PageBreak_out.pdf");
}

Example 2

public static void PageBrakeExample02()
{
    // Create PdfFileEditor object
    PdfFileEditor fileEditor = new PdfFileEditor();

    fileEditor.AddPageBreak(dataDir + "Sample-Document-02.pdf",
        dataDir + "PageBreakWithDestPath_out.pdf",
        new PdfFileEditor.PageBreak[]
        {
            new PdfFileEditor.PageBreak(1, 450)
        });
}

Example 3

public static void PageBrakeExample03()
{
    using (Stream src = new FileStream(dataDir + "Sample-Document-03.pdf", FileMode.Open, FileAccess.Read))
    {
        using (Stream dest = new FileStream(dataDir + "PageBreakWithStream_out.pdf", FileMode.Create, FileAccess.ReadWrite))
        {
            PdfFileEditor fileEditor = new PdfFileEditor();
            fileEditor.AddPageBreak(src, dest,
                new PdfFileEditor.PageBreak[]
                {
                    new PdfFileEditor.PageBreak(1, 450)
                });
        }
    }
}
