Page Numbering in Template

[dh29]

I have a PDF template defined and want to add automatic page numbering.

The 'demo' example shows:

Code: Select all

PdfPageNumberField pageNumber = new PdfPageNumberField();
PdfPageCountField pageCount = new PdfPageCountField();
PdfCompositeField pageNumberLabel = new PdfCompositeField();
pageNumberLabel.AutomaticFields = new PdfAutomaticField[] { pageNumber, pageCount };

I am using the Free Spire.PDF for .NET. I don't seem to have the above classes e.g. 'PdfPageNumberField' etc... Is this correct?

Is there any other way of adding page numbers to a PDF template?

Hello,

Thanks for your inquiry.
I have tested your issue with Free Spire.PDF，it worked well in our side.
The PdfPageNumberField is in Spire.Pdf.AutomaticFields namespace.
Here is the code about template defined and automatic page numbering for your reference.

Code: Select all

PdfDocument doc = new PdfDocument();

            //margin
            PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
            PdfMargins margin = new PdfMargins();
            margin.Top = unitCvtr.ConvertUnits(2f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Bottom = margin.Top;
            margin.Left = unitCvtr.ConvertUnits(0.5f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Right = margin.Left;
            SetDocumentTemplate(doc, PdfPageSize.A4, margin);
            doc.SaveToFile("output.pdf");
            System.Diagnostics.Process.Start("output.pdf");
        }
        static void SetDocumentTemplate(PdfDocument doc, SizeF pageSize, PdfMargins margin)
        {
            PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left);
            PdfPageTemplateElement bottomSpace = new PdfPageTemplateElement(pageSize.Width, margin.Bottom);
            bottomSpace.Foreground = true;
            doc.Template.Bottom = bottomSpace;
            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 9f, FontStyle.Italic));         
            float y = 0;
            PdfPageNumberField pageNumber = new PdfPageNumberField();
            PdfPageCountField pageCount = new PdfPageCountField();
            PdfCompositeField pageNumberLabel = new PdfCompositeField();
            pageNumberLabel.AutomaticFields = new PdfAutomaticField[] { pageNumber, pageCount };       
            pageNumberLabel.Brush = PdfBrushes.Black;
            pageNumberLabel.Font = font;
            pageNumberLabel.StringFormat = format;
            pageNumberLabel.Text = "page {0} of {1}";
            pageNumberLabel.Draw(bottomSpace.Graphics, pageSize.Width - 150, y);
        }

Hi Sweety1,

Thanks for your prompt reply.
Looks like a 'school-boy error' from me...I'd searched the Spire.Pdf-FE.chm help file...but obviously not well enough.
I'll give it a go and let you know how I get on.
