positioning text using itextSharp in C3 -

i trying generate pdf on button click. having challenge design page. if can on, how position text in particular position.

say want address in top right corner , heading in center.

here code working on:

private void pdf_btn_click(object sender, eventargs e) {     savefiledialog svg = new savefiledialog();     svg.showdialog();     using (filestream stream = new filestream(svg.filename + ".pdf", filemode.create))     {         // create document object         var document = new document(pagesize.a4, 50, 50, 25, 25);         // create new pdfwrite object, writing output memorystream         // var output = new memorystream();         var writer = pdfwriter.getinstance(document, stream);                        document.open();         // first, create our fonts... (for more on working w/fonts in itextsharp, see: http://www.mikesdotnetting.com/article/81/itextsharp-working-with-fonts         var titlefont = fontfactory.getfont("arial", 18, convert.toint32(font.bold));         var addressfont = fontfactory.getfont("arial", 7, convert.toint32(font.bold));         var boldtablefont = fontfactory.getfont("arial", 12, convert.toint32(font.bold));         var endingmessagefont = fontfactory.getfont("arial", 10, convert.toint32(font.italic));         var bodyfont = fontfactory.getfont("arial", 12);         // add "" title         document.add(new paragraph("certificate of analysis", titlefont));         // add address          var text = document.add(new paragraph("abc company", addressfont));         document.add(new paragraph("tel:(xx) xxx-xxxx, (xxx) xxx-xxx", addressfont));         document.add(new paragraph("fax: (xxx) xxx-xxx, , addressfont));         document.close();         stream.close();     }             } 

there different ways achieve want.

currently, telling itext layout. if want center text "certificate of analysis", change alignment of paragraph this:

paragraph header = new paragraph("certificate of analysis", titlefont); header.alignment = element.align_center; document.add(header); 

if want text "abc company" right-aligned, can change alignment this:

paragraph company = new paragraph("abc company", addressfont); company.alignment = element.align_right; document.add(company); 

of course: when add company, start on new line under header. maybe want text on same line.

in case, why not use pdfptable?

pdfptable mytable = new pdfptable(3); mytable.widthpercentage = 100; pdfpcell mydate = new pdfpcell(new phrase("april 22, 2015", myfont)); mydate.border = rectangle.no_border; mytable.addcell(mydate); pdfpcell header = new pdfpcell(new phrase("certificate of analysis", titlefont)); header.border = rectangle.no_border; header.horizontalalignment = element.align_center; mytable.addcell(header); pdfpcell address = new pdfpcell(new phrase("company address", addressfont)); address.border = rectangle.no_border; address.horizontalalignment = element.align_right; mytable.addcell(address); doc.add(mytable); 

now available width of page divided in three, date aligned left, header centered, , address aligned right. obviously, can add more data pdfpcell , more rows pdfptable. simple proof of concept.

another option, add text @ absolute position (using coordinates). can done using columntext object. there plenty of examples on in the best itext questions on stackoverflow
