This property can be used to verify that the overall image property state associated with some calculation is still the same as that used for a previous calculation. Changes to pixel data will change this count only once (when the Modified property is set True); use ActiveFrameUpdateCount for counting further image changes.
Changes made via the Properties or LookupTables collections are not captured by this change counter. If your calculation depends on the state of LookupTables or user-assigned image properties, then you will need to check those directly for changes.
