public interface Corrector

Interface for PDF corretors.

Often PDF documents generated by various document to PDF converters have an invalid structure that upsets PDF-AS. The correction mechanism allows these documents to be corrected before being signed.

A PDF corrector takes an incorrect PDF document and transforms it into a correct one.

Note that correcting a document destroys all signatures in that document, so never correct an already signed document.
