Problem with displaying image using Qlabel

Hi........
I have a problem while displaying an image in label. when u simply open l.png its image display is horizontal but when u open with code display is in vertical. i want the image as it is seen in simply opening and no scrollbar should come full image should be displayed on the label with no scollbars.

Code:

imageLabel = new QLabel;
    imageLabel->setBackgroundRole(QPalette::Base);
    imageLabel->setSizePolicy(QSizePolicy::Ignored,QSizePolicy::Ignored);
    imageLabel->setScaledContents(true);
 
    scrollArea = new QScrollArea;
    scrollArea->setBackgroundRole(QPalette::Dark);
    scrollArea->setWidget(imageLabel);
    setCentralWidget(scrollArea);
 
    setWindowTitle(tr("Image Viewer"));
    resize(800, 900);
 
     QImage image("/home/karl/Desktop/l.tif");
 
 
        imageLabel->setPixmap(QPixmap::fromImage(image));
 
        scaleFactor = 1.0;
 
        scrollArea->setWidgetResizable(1);
