IMcProfileEdgesProfilesAncestor Property

Property Value

Type: McLineProfiles

Unless this is a global McProfileEdges instance, this operator will have an ancestor McLineProfiles object that is itself a child of some McLines or McRegions, which will be descended from some McImage operator. Data from these ancestor objects are relevant to the collection of "edges" detected and maintained by this operator. In particular, the ProfilesAncestor.CountOfProfiles property's current value is always the ancestor McFeatures.Count (McLines and McRegions are both derived from McFeatures). One set of edges is maintained for each of the ProfilesAncestor.CountOfProfiles profiles. Furthermore, edges are detected by the FindEdges method based on the sampled luminance profiles of the ProfilesAncestor, so the Interpretation and sampling parameters of that object will determine what the detection properties of this object will work on. For global instances (ones without a parent operator), then the ProfilesAncestor property is Nothing. In this case, all profile samples are taken from the RawProfiles property, and one set of edges is maintained for each of the supplied raw profiles.
