Try to understand from c# and use in vb.net void SplitePDF( string filepath) { iTextSharp.text.pdf.PdfReader reader = null ; int currentPage = 1; int pageCount = 0; //string filepath_New = filepath + "\PDFDestination\"; System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding(); //byte[] arrayofPassword = encoding.GetBytes(ExistingFilePassword); reader = new iTextSharp.text.pdf.PdfReader(filepath); reader.RemoveUnusedObjects(); pageCount = reader.NumberOfPages; string ext = System.IO.Path.GetExtension(filepath); for ( int i = 1; i { iTextSharp.text.pdf.PdfReader reader1 = new iTextSharp.text.pdf.PdfReader(filepath); string outfile = filepath.Replace((System.IO.Path.GetFileName(filepath)), (System.IO.Path.GetFileName(filepath).Replace( ".pdf" , "" ) + "_" + i.ToString()) + ext); reader1.RemoveUnusedObjects(); iTextSharp.text.Document doc = new iTextSharp.text.Document(reader.GetPageSizeWithRotation(currentPage)); iTextSharp.text.pdf.PdfCopy pdfCpy = new iTextSharp.text.pdf.PdfCopy(doc, new System.IO.FileStream(outfile, System.IO.FileMode.Create)); doc.Open(); for ( int j = 1; j { iTextSharp.text.pdf.PdfImportedPage page = pdfCpy.GetImportedPage(reader1, currentPage); pdfCpy.SetFullCompression(); pdfCpy.AddPage(page); currentPage += 1; } doc.Close(); pdfCpy.Close(); reader1.Close(); reader.Close(); } }

https://csharp.hotexamples.com/examples/iTextSharp.text.pdf/PdfWriter/CreateAnnotation/php-pdfwriter-createannotation-method-examples.html there are so many examples in the link one of them is virtual public PdfAnnotation CreateAnnotation(PdfWriter writer) { PdfAnnotation annotation = writer.CreateAnnotation( new Rectangle(llx, lly, urx, ury), null ); if (newPage != 0) { PdfIndirectReference refi = writer.GetPageReference(newPage); destination.Set(0, refi); } if (destination != null ) annotation.Put(PdfName.DEST, destination); foreach (PdfName key in parameters.Keys) annotation.hashMap[key] = parameters[key]; return annotation; }
