Really? AFAIK png and jpg use compression methods resulting in unpredictable information loss. IMHO converting them to a raw format will not often produce identical data.
Or am I missing a special magic feature?
I think I would rather try to calculate a diff and test the average distance for a threshold passed. Not sure if the result of ->compare can be used for this.
