Break PDF by page numbers

[colinmhart]

Super easy one but I can't seem to get this working
I have a PDF with 100 pages
I want it to break it into two documents
one with pages 1-50 and the other would be pages 51-100
how would I do that?

Hi,

Thanks for your inquiry.
Please see the following code for reference.

Code: Select all

            PdfDocument oldPdf = new PdfDocument();
            oldPdf.LoadFromFile("old.pdf");
            PdfDocument newPdf1 = new PdfDocument();
            PdfDocument newPdf2 = new PdfDocument();
            PdfPageBase page1;
            PdfPageBase page2;

            for (int i = 0; i < 100; i++)
            {
                if (i < 50)
                {
                    //Add same size page for newPdf
                    page1 = newPdf1.Pages.Add(oldPdf.Pages[i].Size, new Spire.Pdf.Graphics.PdfMargins(0));

                    //Create template of the oldPdf page and draw into newPdf page
                    oldPdf.Pages[i].CreateTemplate().Draw(page1, new System.Drawing.PointF(0, 0));
                }
                else
                {
                    //Add same size page for newPdf
                    page2 = newPdf2.Pages.Add(oldPdf.Pages[i].Size, new Spire.Pdf.Graphics.PdfMargins(0));

                    //Create template of the oldPdf page and draw into newPdf page
                    oldPdf.Pages[i].CreateTemplate().Draw(page2, new System.Drawing.PointF(0, 0));
                }
               
            }

            String result1 = "new1.pdf";
            String result2 = "new2.pdf";

            //Save the document
            newPdf1.SaveToFile(result1);
            newPdf2.SaveToFile(result2);
