Problem with loading an Image from raw data

[Dark Harlekin]

Hi everybody,

I'm trying to load an image from raw data, which I get from a database.
For testing purpose I saved the data to a file and wrote the code below but it won't display the image.
I'm not that into processing images, maybe I'm missing something else.

the raw image
an exported version of the image

QByteArray imagesData;
QFile *file = new QFile(QFileDialog::getOpenFileName(this,tr("Open Image"), "", tr("")));
 
if(file->exists())
{
        //get byteArray from raw data file
        file->open(QFile::ReadOnly);
        imagesData = file->readAll();
        file->close();
 
        //Create qimage
        QImage img((const uchar*)imagesData.data(),4320,2880,QImage::Format_RGB888);
 
        QPixmap pix;
        pix.fromImage(img);
 
        ui->label->setPixmap(pix);
}

QByteArray imagesData;
QFile *file = new QFile(QFileDialog::getOpenFileName(this,tr("Open Image"), "", tr("")));

if(file->exists())
{
        //get byteArray from raw data file
        file->open(QFile::ReadOnly);
        imagesData = file->readAll();
        file->close();

        //Create qimage
        QImage img((const uchar*)imagesData.data(),4320,2880,QImage::Format_RGB888);

        QPixmap pix;
        pix.fromImage(img);

        ui->label->setPixmap(pix);
}
