Is Rights issue a public offer?

Indian Contract Act, 1872 mentions that if an offer is made to a specific person or group of persons, which otherwise cannot be accepted by persons other than the ones to whom such an offer is made, it is called as Specific offer.

Keeping this concept into mind, plz clarify if rights issue is a public offer or private (specific offer)? If it is not a public offer, why does minimum subscripttion clause apply to it? Min subscripttion applies only to the IPO and not on FPO.
