Public Shared Sub AddEmptyPageToPdfDocument(pdfFileName As String, pageSize As System.Drawing.SizeF)
	' open PDF document
	Using document As New Vintasoft.Imaging.Pdf.PdfDocument(pdfFileName)
		' get the collection of pages of PDF document
		Dim pages As Vintasoft.Imaging.Pdf.Tree.PdfPageCollection = document.Pages
            
		' add an empty page into collection of pages
		pages.Add(pageSize)
            
		' save changes to a file
		document.SaveChanges()
	End Using
End Sub

/// <summary>

/// </summary>
/// <param name="pdfFileName">The filename of PDF document.</param>
/// <param name="pageSize">The size of page.</param>
public static void AddEmptyPageToPdfDocument(string pdfFileName, System.Drawing.SizeF pageSize)

    // open PDF document
    using (Vintasoft.Imaging.Pdf.PdfDocument document = 
        new Vintasoft.Imaging.Pdf.PdfDocument(pdfFileName))
    {
        // get the collection of pages of PDF document
        Vintasoft.Imaging.Pdf.Tree.PdfPageCollection pages = document.Pages;
            
        // add an empty page into collection of pages
        pages.Add(pageSize);
