How to add Page Numbering in PDF file


Often, we have documents in which it is necessary to make any edits. For example, add page numbering in PDF file!

This sample code will help you to add page numbering in an existing PDF file.

For example : We have the PDF file and we need to add Page Numbering.

Numbering Format: "Page N of M"

We place our page numbers into the footer using a new paragraph.

 

            // Create a footer. 
            HeaderFooter footer = new HeaderFooter(dc, HeaderFooterType.FooterDefault); 
 
            // Create a new paragraph to insert a page numbering. 
            // So that, our page numbering looks as: Page N of M. 
            Paragraph par = new Paragraph(dc); 
            par.ParagraphFormat.Alignment = HorizontalAlignment.Right; 
            CharacterFormat cf = new CharacterFormat() { FontName = "Consolas", Size = 14.0 }; 
            par.Content.Start.Insert("Page ", cf.Clone()); 
             
            

The next step is adding two Fields : FieldType.Page and FieldType.NumPages

            
            // Page numbering is a Field. 
            Field fPage = new Field(dc, FieldType.Page); 
            fPage.CharacterFormat = cf.Clone(); 
            par.Content.End.Insert(fPage.Content); 
            par.Content.End.Insert(" of ", cf.Clone()); 
            Field fPages = new Field(dc, FieldType.NumPages); 
            fPages.CharacterFormat = cf.Clone(); 
            par.Content.End.Insert(fPages.Content); 
            footer.Blocks.Add(par);
