Hi experts,

How do I load data from a QImage into a QByteArray ? I need only the raw data of the image in the array. For example, if I have a PNG, I only need to read the raw data of the image.

Thanks,
Peter

You can use 'QImage::bits()' (http://doc.qt.nokia.com/latest/qimage.html#bits-2) for that, e.g.
QImage img;

//...

QByteArray arr((char*)img.bits(),img.byteCount());

Open in new window
