Byte Offset	Name	Description
4	mode	Mode for automatic and manual gain/exposure control. See Sensor Controls and Gain Modes Value Description 0 High bit depth automatic gain control (for 10 to 16 bit image conversion to 8 bits) 1 Manual gain and exposure control - set agHoldmax/agHoldmin for high bit depth imagers or set sensor Exposure and Gains if available in SLASetADCParameters_t 2 SightLine automatic exposure and gain control (SLA auto gain algorithm adjusts parameter registers on the sensor, see SLASetADCParameters_t) 4000/17XX only, New 3.1 3 Camera automatic exposure and gain control (camera controls its gain and exposure, see SLASetADCParameters_t) 4000/17XX only, New 3.6
5-6	agHoldmax	Autogain Max value used with Manual Gain mode control for high bit depth images (max value maps to 255 in 8 bit output)
7-8	agHoldmin	Autogain Min Value with Manual Gain mode control for high bit depth images (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	Camera Index
14-15	minAGRange	High Bit Depth Autogain mode: Minimum spread of auto gain. 0 = does nothing, 200 = max - min scale range must be at least 200. Prevents over-gaining of flat scenes. New 3.0 SightLine Auto Gain Mode mode: Difference limit for updates. 0 = does nothing, 10 = if image average is within 10 of target Brightness, don't update exposure and gain. Prevents image flashing and excessive setting of sensor registers. New 3.1
16	agRate8	Auto gain update rate. 1 = minimum rate, 255 = maximum rate, 32 = default. New 3.0 Use Manual mode to stop AGC updates
17	minExp	Minimum exposure or integration time 0 to 255. Default(0) = ignored. For cameras that support exposure control, see SLASetADCParameters_t. New 3.2
18	maxExp	Maximum exposure or integration time 0 to 255. Default(0) = ignored. For cameras that support exposure control, see SLASetADCParameters_t. New 3.2
19	rejectDarkTail	Reject or ignore 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 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
