Property Value

Type: Double
The low limit of the angle range (in radians). Default value is -pi/4.

Events

Event Type	Reason
ICogChangedEvent Changed	Fires when this property changes. The following state flag may be affected: SfLow
ICogChangedEvent Changed	Fires when this property changes and the high limit is also changed. The following state flags may be affected: SfLow SfHigh

Remarks

The low limit is only used if the Configuration property is set to LowHigh. In this case PMRedLine will find pattern instances whose result angle lies between the low and high limit values.

The result angle is measured from the selected space of the InputImage to the coordinate space of the pattern (as defined by the pattern Origin). It can be accessed using the Rotation property of the CogTransform2DLinear returned by the GetPose method of the CogPMRedLineResult class.

You can specify any value for the low angle limit. Setting the low limit to a value larger than the high limit also sets the high limit to the new value.

The tool always returns angle results in the range -pi to +pi.
