pdf manupulation problem

You need to create a template PDF, set its page size as A3, and then draw the content of page 1 to page 50 to the left and the content of page 51 to page 59 to the right of the pages in the template pdf.

Refer the following code:

//Load a PDF
PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("Sample.pdf");
//Create a blank template PDF
PdfDocument newPdf = new PdfDocument();
//Loop through the pages in the PDF
foreach (PdfPageBase page in pdf.Pages)
{
//Add pages to the template PDF and set page size as A3
PdfPageBase newPage = newPdf.Pages.Add(PdfPageSize.A3, new PdfMargins(0));
//Draw the content of the pages in the PDF to the pages of the template PDF at specified location
page.CreateTemplate().Draw(newPage, new PointF(0, 0));
}
//Save the result document
newPdf.SaveToFile("Result.pdf", FileFormat.PDF);
