screen shot m adding images in pdf file generate pdf document problem automatically adding 1st page blank page , remaining pages contain images fine. how should overcome problem. 

pdfpath = dir + "/" + txtfilename.gettext().tostring() + ".pdf";  string pdffilename = txtfilename.gettext().tostring() + ".pdf"; pdfwriter writer; file file = new file(dir, pdffilename); document document = new document();  try {      writer = pdfwriter.getinstance(document,             new fileoutputstream(file));     headerfooterpageevent event = new headerfooterpageevent();     writer.setpageevent(event); } catch (filenotfoundexception e) {     e.printstacktrace(); } catch (documentexception e) {     e.printstacktrace(); } document.open();  image image = null;  (int = 0; < listofimage.size(); i++) {     string imgfilename = listofimage.get(i).tostring();     try {          image = image.getinstance(imgfilename);     } catch (badelementexception e) {          e.printstacktrace();     } catch (malformedurlexception e) {         e.printstacktrace();     } catch (ioexception e) {          e.printstacktrace();     }      float scaler = ((document.getpagesize().getwidth()             - document.leftmargin() - document.rightmargin()) / image             .getwidth()) * 90;     log.i("scale percentage", scaler + "");     image.scalepercent(scaler);      try {          document.newpage();         document.add(image);         document.addauthor("genetech solutions");      } catch (documentexception e) {         e.printstacktrace();     } }  document.close();

headerfooterpageevent consists of:

public void onendpage(pdfwriter writer, document document) {     columntext.showtextaligned(writer.getdirectcontent(), element.align_center, new phrase("generated snap scanner powered genetech solutions"), 180, 30, 0);     columntext.showtextaligned(writer.getdirectcontent(), element.align_center, new phrase("page " + document.getpagenumber()), 550, 30, 0); }

screen shot

i burnt down code following test case, removing try-catch constructs keep short , inlining page event listener:

@test public void testyasirahmedkhanoriginal() throws ioexception, documentexception {     list<string> listofimage = collections.ncopies(3, "src/test/resources/mkl/testarea/itext5/layer/willi-1.jpg");     // collections.singletonlist("src/test/resources/mkl/testarea/itext5/layer/willi-1.jpg");     file file = new file(result_folder, "yasirahmedkhanoriginal.pdf");      document document = new document();     pdfwriter writer = pdfwriter.getinstance(document, new fileoutputstream(file));     writer.setpageevent(new pdfpageeventhelper()     {         public void onendpage(pdfwriter writer, document document)         {             columntext.showtextaligned(writer.getdirectcontent(), element.align_center, new phrase("generated snap scanner powered genetech solutions"), 180, 30, 0);             columntext.showtextaligned(writer.getdirectcontent(), element.align_center, new phrase("page " + document.getpagenumber()), 550, 30, 0);         }     });     document.open();      (int = 0; < listofimage.size(); i++)     {         string imgfilename = listofimage.get(i).tostring();         image image = image.getinstance(imgfilename);          float scaler = ((document.getpagesize().getwidth() - document.leftmargin() - document.rightmargin()) /                 image.getwidth()) * 90;         image.scalepercent(scaler);          document.newpage();         document.add(image);         document.addauthor("genetech solutions");     }      document.close(); }

(unwantedpage.java)

the result:

the result pdf

no empty first page, should be...

thus, either op additional causes empty page or uses old itext version may have had bug in respect.
