cannot save QPixmap as jpeg

[arunredi]

Hi,
I'm not able to save a pixmap data to jpeg format. but if I opt of png then it works. what am I missing here?

Note: I have my Qt built statically and thats when all this kind of wierd problems are showing up.

here is my code:

originalPixmap = QPixmap::grabWindow(QApplication::desktop()->winId());
     screenshotLabel->setPixmap(originalPixmap.scaled(screenshotLabel->size(),
                                                      Qt::KeepAspectRatio,
                                                      Qt::SmoothTransformation));
     QString format = "jpeg";
     QString initialPath = QDir::currentPath() + tr("/imagecapture/untitled.") + format;
	 QString fileName = initialPath;
     if (!fileName.isEmpty())
         originalPixmap.save(fileName, format.toAscii());

originalPixmap = QPixmap::grabWindow(QApplication::desktop()->winId());
     screenshotLabel->setPixmap(originalPixmap.scaled(screenshotLabel->size(),
                                                      Qt::KeepAspectRatio,
                                                      Qt::SmoothTransformation));
     QString format = "jpeg";
     QString initialPath = QDir::currentPath() + tr("/imagecapture/untitled.") + format;
	 QString fileName = initialPath;
     if (!fileName.isEmpty())
         originalPixmap.save(fileName, format.toAscii());
