I've got raw image bytes - just a series of 8-bit grayscale bytes and a width and height - and I need to display them in a Qml page with high efficiency.
Right now I'm creating a QImage from the raw bytes which I am providing to the Qml page via a class derived from QQuickImageProvider, but I think I could also use glTexImage2D() to construct an OpenGL texture which I then send to the Qml page using a QQuickTextureFactory.
Is the extra work to generate an OpenGL texture worth it (in terms of efficiency)? Or is there even a third way I don't know of?
Thanks,
Chris
