BalanceWhiteAuto: Querying and setting a sub-region
You can set an image area (sub-region) for auto white balance to be applied. Normally, the total image ROI is used for the white balance ROI. To set a different sub-region, first disable SubRegionFollowSource of the white balance ROI. Then you can set the new values for the position and size.
