(QCameraImageProcessing )the function "setCorlorFilter()" and "setWhiteBalanceMode()" does not work

[FeiKing]

I can use the QCameraImageProcessing to change the camera' s Contrast , SharpeningLevel,Brightness,but i can not changed the colorfilter and the WhiteBalanceMode. (the function "setCorlorFilter()" and "setWhiteBalanceMode()" does not work as what i think)
i used the QCamera ,QCameraImageCapture,QCameraViewfinder,i don't know how to slove this bug.

Hi and welcome to devnet,

Not all backends support every operations.

You should check with the isWhiteBalanceModeSupported and isColorFilterSupported methods.

@SGaist thanks very much.
i used the isWhiteBalanceModeSupported and isColorFilterSupported methods，and i found only support the WhiteBalanceAuto, i want to know why and what can do for this case? Could you tell me?

Like I wrote before, it depends on the backend.

What you can do ? Check which backend you are using. Once identified, whether the feature you need can be implemented there and if so, implement the missing parts and contribute them back to Qt.
