Properties
- AllowSignatureInvalidation
Consent to marking a digitally signed document. Marking rewrites the file, which invalidates every signature; without this opt-in a signed input is refused with PdfSignatureInvalidationException rather than silently breaking its signatures. Default:
false.
- PageIndices
The zero-based indices of the pages to mark or clear;
null(default) for every page. An index outside the document fails the call.
- Password
The password used to open an encrypted source document. The output is written unencrypted.
- ReplaceExisting
Whether a watermark this engine applied earlier is removed from each page before the new one is laid, so marking a document twice replaces the mark instead of stacking a second one. Default:
true.
