(although the latter would obviously be a massive overkill for image data coming from a file since that's what the Image element provides out of the box anyway). This can then be used with QPainter, can be passed to widgets, and can also be utilized in Qt Quick scenes via custom image provider implementations.
Getting a QImage that contains the pixel data of an image loaded from a file is fairly self-explanatory: QImage is the most common container for image data in Qt applications. Inside QImage (with a touch of Qt Quick and OpenGL)
