Class Overview
Handles storing signatures. A signature is usually an ink signature (hand-written signature) that
can be added to a PDF as an InkAnnotation. Additionally, a signature can be associated
with a Signer for digitally signing a PDF.
Implement this class when creating your own signature storage, which you can then pass to the
SignatureOptions.Builder. Additionally, you can use our
default DatabaseSignatureStorage with your own database name.
To set a default signature storage that will be used when the ElectronicSignatureFragment
is invoked by the framework, use setSignatureStorage(SignatureStorage).
