当 completed is set, the function is invoked when the data 可用。 format and pixelSize are set upon completion together with data .
注意： This is a RHI API with limited compatibility guarantees, see QRhi 了解细节。
Callback that is invoked upon completion, on the thread the
QRhi
operates on. Can be left set to
