Reason

CogCaliper Changed

Fires when the value of this property changes.

The following state flag may be affected:

SfEdge0Position

Remarks

The expected position of the edge with respect to the edge model origin. In single edge mode, the reported edge location is offset by the Edge0Position value.

If you are using edge-pair mode, you need to specify values for both Edge0Position and Edge1Position. The values you specify determine both the expected width of the edge pair and the location which is reported for the edge pair. If you want to specify an edge model with its origin in the center, you should specify a value for Edge0Position that is the negative of the Edge1Positionvalue, as shown in the following figure:

Default Value: 0.0
