Indicates whether FindEdges might find different edges than the current set.

A Boolean value.  

object.IsStale

The IsStale Property syntax has these parts:

IsStale will be True whenever any parameter or profile data changes that might affect profile weighting or edge detection. IsStale goes False when FindEdges is called for all profiles where a recomputation is necessary (by default FindEdges will work on all profiles, so IsStale will be set False).

IsStale also goes False after an assignment is made to the WeightedProfiles property for all stale profiles. An assignment to WeightedProfiles clears IsStale even though FindEdges might subsequently find different edges; by assigning to WeightedProfiles you are effectively bypassing the first, weighting phase of FindEdges with your own weighting.
