iTextSharp - Don't display page numbers if only one page -


i have pdf generated using itextsharp displays "page 1/4" etc. thing in footer. works fine , implemented using pdftemplate set in onendpage() method total number of pages added in onclosedocument() method.

what remove if there 1 page in document. i've tried in onclosedocument() method, doesn't remove template:

        public override void onclosedocument(pdfwriter writer, document document)         {             base.onclosedocument(writer, document);              if (writer.pagenumber >= 3)             {                 template.begintext();                 template.setfontandsize(f_cn, cocservice.footerfont.size);                 template.settextmatrix(0, 0);                 template.showtext("" + (writer.pagenumber - 1));                 template.endtext();             }             else             {                 template.reset();             }         }

just reference, here's relevant code onendpage() method:

        public override void onendpage(pdfwriter writer, document document)         {             base.onendpage(writer, document);              int pagen = writer.pagenumber;             string text = "page " + pagen.tostring() + "/";              float len = f_cn.getwidthpoint(text, cocservice.footerfont.size);             itextsharp.text.rectangle pagesize = document.pagesize;             cb.setrgbcolorfill(100, 100, 100);             cb.begintext();             cb.setfontandsize(f_cn, cocservice.footerfont.size);             cb.settextmatrix(document.leftmargin+520, pagesize.getbottom(document.bottommargin)+33);             cb.showtext(text);             cb.endtext();             cb.addtemplate(template, document.leftmargin + 520 + len, pagesize.getbottom(document.bottommargin)+33);         }

you writing text content stream in onendpage() method, , there's no way remove after fact because stream may have been sent outputstream.

the best way avoid having page numbers on document if there's 1 page, add page numbers in second go. take @ twopasses example, says "second pass". imo, elegant way solve problem. ask reader number of pages. if it's 1, nothing. if it's more, add page x of y.
