Enum PdfSignatureModificationDetectionPermission 

pub enum PdfSignatureModificationDetectionPermission {
    Mdp1,
    Mdp2,
    Mdp3,
}

The modification detection permission (MDP) applicable to a single digital signature in a PdfDocument.

For more information on MDP, refer to “DocMDP” in Section 8.7.1 on page 731 of The PDF Reference, Sixth Edition. The permission levels in this enumeration correspond to those listed in table 8.104 on page 733.

Variants

Mdp1

MDP access permission level 1: no changes to the document are permitted; any change to the document invalidates the signature.

Mdp2

MDP access permission level 2: permitted changes are filling in forms, instantiating page templates, and signing; other changes invalidate the signature.

Mdp3

MDP access permission level 3: permitted changes are the same as for level 2, as well as annotation creation, deletion, and modification; other changes invalidate the signature.
