Hi ChrisW67

Thanks for your help..

the implementation Code for the Function LoadPDF

Qt Code: 
  1. extern inline QPixmap LoadPDF(QString fn, int Page, int w )
  2. {
  3.         QString tmp, cmd1, cmd2;
  4.         const QString pdfFile = PathConvert(fn);
  5.         const QString tmpFile = PathConvert(QDir::homePath()+"/sctodaytmps.png");
  6.     const QString qttmpFile = QDir::homePath()+"/sctodaytmps.png";
  7.         QPixmap pm;
  8.     tmp.setNum(Page);
  9.         int ret = -1;
  10.         tmp.setNum(Page);
  12.     args.append("-sDEVICE=png16m");
  13.     args.append("-r72");
  14.     args.append("-dGraphicsAlphaBits=4");
  15.     args.append("-o");
  16.         args.append(tmpFile);
  17.     args.append("-dFirstPage="+tmp);
  18.         args.append("-dLastPage="+tmp);
  19.         args.append(pdfFile);
  20.         ret = callGS(args);
  21.     ////////qDebug() << "### ret " << ret;
  22.         if (ret == 0)
  23.         {
  24.         QPixmap tmpimage(qttmpFile);
  25.         QPixmap penna = tmpimage.scaledToWidth(w);
  26.         tmpimage.detach();
  27.         QFile lastaction(qttmpFile);
  28.         lastaction.remove();
  30.                 p.begin(&penna);
  31.                 p.setBrush(Qt::NoBrush);
  32.                 p.setPen(QPen(QBrush(Qt::black),2,Qt::SolidLine));
  33.                 p.drawRect(0, 0, penna.width(), penna.height());
  34.                 p.end();
  35.         return penna;
  36.         }
  37.         return pm;
  38. }

I have tested the way you suggested with this code

Qt Code: 
  1. pdfFile   = LoadPDF( fixurl.absoluteFilePath() ,page,large);
  2.  
  3.                                     if (pdfFile.isNull())
  4.                                         QMessageBox::warning(0,"pdfFile.isNull() = True ","pdfFile.isNull() = True");
  5.  
  6.                                     QImage tImage =  pdfFile.toImage();
  7.                                     if (tImage.isNull())
  8.                                         QMessageBox::warning(0,"tImage.isNull() = True ","tImage.isNull() = True");

I'm getting both of the messages .. that mean it's not loading and converting to QPixmap

I think I will miss with the function more tomorrow..
