Message ID 0x71

Byte Offset	Name	Description
4	mode	Mode (1 = freeze Autogain at min/max below)
5-6	agHoldmax	Autogain Max value (max value maps to 255 in 8 bit output)
7-8	agHoldmin	Autogain Min Value (min value maps to 0 in 8 bit output)
9	rowROIPct	Row ROI for Autogain stats. Row Offset in % of image height (255=100%); Full image(default) = 0
10	colROIPct	Col ROI for Autogain stats. Col Offset in % of image width (255=100%); Full image(default) = 0
11	highROIPct	High ROI for Autogain stats. Height in % of image height (255=100%); Full image(default) = 255
12	wideROIPct	Wide ROI for Autogain stats. Width in % of image width (255=100%); Full image(default) = 255
13	cameraIndex	Index of the camera where values are coming from
14-15	minAGRange	Minimum spread of auto gain. 0 = does nothing, 200 = max - min scale range must be at least 200. Prevents over-scaling of flat scenes. New 3.00
16	agRate8	Auto gain update rate. 0 = reset to 32, 1 = minimum rate, 255 = maximum rate, 32 = default. New 3.00 Use freeze Autogain to stop AGC updates
17	minExp	Minimum exposure or integration time New 3.1
18	maxExp	Maximum exposure or integration time New 3.1
19	rejectDarkTail	Reject or ignore the this percent/10 of the left/dark side of the histogram when calculating Autogain. 0 = reject none, 10 = reject 1.0%, 255 = reject 25.5%. Useful when there are a small number of very dark pixels in a scene. New 3.4
20	rejectBrightTail	Reject or ignore the this percent/10 of the right/bright side of the histogram when calculating Autogain. 0 = reject none, 10 = reject 1.0%, 255 = reject 25.5%. Useful when there are a small number of very bright pixels in a scene. New 3.4
