CrDeviceProperty_AF_Area_Position

Set the AF Area Position(x,y)

CrDataType: CrDataType_UInt32Range

Value	Explanation
0x00000000	min
0xFFFFFFFF	max
1	step

Set the center position of the AF frame.

The x coordinate is set in the upper two bytes and the y coordinate is set in the lower two bytes

The range of X is 0 ~ 639 (0x027F), and the range of Y is 0 ~ 479 (0x01DF).

AF frame size is acquired by CrFocusFrameInfo.

CrFocusFrameInfo is in LiveViewProperty.

The settable area is more inside by half the frame size than CrFocusFrameInfo.xDenominator/yDenominator.

Note:

The range in which the coordinates can be specified varies depending on the model, aspect setting, and AF setting.
