Horizontally and Vertically Split a PDF Page into multiple Pages in C#

Spire.PDF supports to horizontally and vertically split a PDF page into two or more pages. This article will show you how to use Spire.PDF to accomplish this function.

The sample PDF file:

Detail steps:

Step 1: Load the sample PDF file and get the first page.

PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("New Zealand.pdf");

PdfPageBase page = pdf.Pages[0];

Step 2: Create a new PDF file and remove page margins.

PdfDocument newPdf = new PdfDocument();
newPdf.PageSettings.Margins.All = 0;

Step 3: Set page width and height in order to horizontally or vertically split the first page into 2 pages.

//Horizontally Split
newPdf.PageSettings.Width = page.Size.Width;
newPdf.PageSettings.Height = page.Size.Height / 2;
//Vertically split
//newPdf.PageSettings.Width = page.Size.Width / 2;
//newPdf.PageSettings.Height = page.Size.Height;

Step 5: Add a new page to the new PDF file.

PdfPageBase newPage = newPdf.Pages.Add();

Step 6: Create layout format.

PdfTextLayout format = new PdfTextLayout();
format.Break = PdfLayoutBreakType.FitPage;
format.Layout = PdfLayoutType.Paginate;

Step 7: Create template from the first Page of the sample PDF, and draw the template to the new added page with the layout format.

page.CreateTemplate().Draw(newPage, new PointF(0, 0), format);

Step 8: Save and close.

newPdf.SaveToFile("SplitPage.pdf");
newPdf.Close();
pdf.Close();
