[Interest] Qt and OpenCL crash course

[Jason H]

I need to do some elementary graphics operations on QPixmap or QImage. I can do these in Qt to some extent already. But for this latest project I will be processing 4k resolution images.
My operations are:
Translate off origin
Rotate by an acute angle (around a point sometimes not in the image) 
Pixel value normailzation

To what extent does Qt support these operations in a hardware accelerated manner? Or how hard is it for me to use the hardware to produce those functions to inter-operate with Qt?

Many thanks!
