Problem with displaying image using Qlabel

[deck99]

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.

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);

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);

To copy to clipboard, switch view to plain text mode

I dont quite understand! If you don't want scrollbars, then don't put your label into a scrollarea. setScaledContents should scale your pixmap to fit the labels size.

As to the rotation: Could it be that your image viewer automatically rotates the file due to some meta information e.g. xmp or exif orientation? Because I don't think that QLabel will rotate the image by itself.

Try an image from a different source.
