A read-only property specifying whether the ProfileValues need to be recomputed.

A Boolean value.  

object.IsStale

The IsStale Property syntax has these parts:

Whenever ProfileValues is accessed, it will be computed as necessary using the ancestor McFeatures features and the ancestor McImage for luminance and, optionally, intensity calibration data. This recomputation will only occur if the IsStale property is True. An object manager property change notification is fired with ID_IMcLineProfiles_IsStale when IsStale goes True for any reason, but no notification is fired when it goes False (which will occur after any access to the ProfileValues property).

IsStale will go True whenever the ancestor McLines or McRegions changes, when the ancestor McImage luminance data changes or when any McLineProfiles property is changed.
