class HexaPDF::Type::AcroForm::SignatureField::SeedValueDictionary

Parent	HexaPDF::Dictionary
Extended With	HexaPDF::Utils::BitField

A seed value dictionary contains information that constrains the properties of a signature that is applied to the associated signature field.

Flags¶ ↑

If a flag is set it means that the associated entry is a required constraint. Otherwise it is optional.

The available flags are: filter, sub_filter, v, reasons, legal_attestation, add_rev_info, digest_method, lock_document and appearance_filter.

See: PDF2.0 s12.7.5.5
