The resulting features are those from the original state that also match features from the intersecting features. The interesected McFeatures is not affected.
This method behaves differently depending on the McFeatures type and state. For McPoints, McLines and McRegions with the mcofKeepRegionsAsUnion OptionFlags off, features that are identical to ones in the subtracted McFeatures are preserved, all others are removed (that is, only features common to both are preserved).; source features that have no match are ignored. In this mode, the source McFeatures must be of the same type (McPoints, McLines or McRegions) as this one.
For McRegions with the mcofKeepRegionsAsUnion OptionFlags on, any McFeatures type may be used as a source. Each pixel from the intersecting McFeatures, treated as a scan list, is AND'ed with the McRegions pixels. Only pixels that are foreground in both will be preserved. New Identifiers are assigned to the resulting connected regions.
