PdfLoadedDocument save time

[Martin]

When loading a 59mb PDF using PdfLoadedDocument, adding a page number to each page and then saving it is taing over 2 minutes to to save the document. Is this normal?

Code is as follows:

        Dim loadedDocument As PdfLoadedDocument = New PdfLoadedDocument(DocPath)

        Dim paginationFont As PdfFont = New PdfStandardFont(PdfFontFamily.Helvetica, 8.0F)

        Dim brush As PdfBrush = PdfBrushes.Black

        Dim pageNumber As PdfPageNumberField = New PdfPageNumberField(paginationFont, brush)

        For i As Integer = 0 To loadedDocument.Pages.Count - 1

            pageNumber.Draw(loadedDocument.Pages(i).Graphics, New PointF(loadedDocument.Pages(i).Size.Width - 20, loadedDocument.Pages(i).Size.Height - 20))

            If PrefixPageNumberChar = 1 Then

                Dim page As PdfLoadedPage = TryCast(loadedDocument.Pages(i), PdfLoadedPage)

                Dim graphics As PdfGraphics = page.Graphics

                graphics.DrawString(PrefixCharacter, paginationFont, brush, New PointF(loadedDocument.Pages(i).Size.Width - 30, loadedDocument.Pages(i).Size.Height - 20))

            End If

        Next

        loadedDocument.Save()

        loadedDocument.Close(True)
