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 doc = new Document(_dataDir + "Sample-Document-01.pdf");
        // Instantiate blank Document instance
        Document dest = new Document();
        // Create PdfFileEditor object
        PdfFileEditor fileEditor = new PdfFileEditor();
        fileEditor.AddPageBreak(doc, 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() {
        Stream src = new FileStream(_dataDir + "Sample-Document-03.pdf", FileMode.Open, FileAccess.Read);
        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) });
        dest.Close();
        src.Close();
    }
