 public class itseventshandler : pdfpageeventhelper          {              pdftemplate total;              basefont helv;                public override void onendpage(pdfwriter writer, document document)              {  itextsharp.text.image jpg = itextsharp.text.image.getinstance("c:/users/public/pictures/sample pictures/penguins.jpg");              jpg.scalepercent(35f);              jpg.setabsoluteposition(130f, 240f);                itextsharp.text.image imgfoot = jpg;                  //header image                   itextsharp.text.image imghead = itextsharp.text.image.getinstance("c:/users/public/pictures/sample pictures/penguins.jpg");                   imgfoot.setabsoluteposition(0, 0);                  imghead.setabsoluteposition(0, 0);                  imgfoot.scaleabsolute(826, 1100);                  pdfcontentbyte cbhead = writer.directcontent;                  pdftemplate tp = cbhead.createtemplate(2480, 370); // units in pixels i'm not sure if thats correct units                  tp.addimage(imghead);                   pdfcontentbyte cbfoot = writer.directcontent;                  pdftemplate tpl = cbfoot.createtemplate(2480, 664);                  tpl.addimage(imgfoot);                  cbhead.addtemplate(tp, 0, 715);                   helv = basefont.createfont(basefont.helvetica, basefont.winansi, basefont.not_embedded);                   /*pdfcontentbyte cb = writer.directcontent;                  cbfoot.savestate();                  document.setmargins(35, 35, 100, 82);                  cb.restorestate();*/                   //document.newpage();                   base.onstartpage(writer, document);              }               public override void onopendocument(pdfwriter writer, document document)              {                  total = writer.directcontent.createtemplate(100, 100);                  total.boundingbox = new itextsharp.text.rectangle(-20, -20, 100, 100);                  helv = basefont.createfont(basefont.helvetica, basefont.winansi, basefont.not_embedded);              }          }

code creating header images; images looks big.tried use imgfoot.scaleabsolute(826, 1100); dosent worked result image shows half.please me resolve. ...............................................................................................

assuming talking imghead, creating image width of 826 user units , height of 1100 user units. adding image @ position (0, 0) of form xobject width of 2480 user units (that's sufficient) , height of 370 user units (that's not sufficient height of image 1100 user units).

you image shows half. correct: have clipped image 33.6% of height (370 / 1100). change height value of form xobject tp image fits , you've solved problem.

also: user units aren't pixels! default 1 user unit corresponds 1 point.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
