ICAP_THRESHOLD

Description:	Specifies the dividing line between black and white. This is the value the Source will use to threshold, if needed, when ICAP_PIXELTYPE = TWPT_BW. The value is normalized so there is no unit of measure associated with this ICAP.
Remarks:	Application will typically set ICAP_BITDEPTHREDUCTION to TWBR_THRESHOLD to use this capability.
Data type:	Single(float)
Default value:	128
Allowed values:	0 to 255
CapType for GET:	TW_ENUMERATION, TW_ONEVALUE, TW_RANGE
CapType for SET:	TW_ENUMERATION, TW_ONEVALUE, TW_RANGE
