trailingBytesAreIncrementalUpdate property
When unsignedTrailingBytes is > 0, whether the trailing region looks
like a well-formed PDF incremental update (it contains a startxref and a
terminating %%EOF). null when there are no trailing bytes. false
signals raw appended data that is not part of the PDF revision structure —
a strong tampering indicator.
Implementation
final bool? trailingBytesAreIncrementalUpdate;
