Limitations
The approach in this project has the following limitations:
- The
PdfDocumentProcessorclass allows you to apply only one digital signature to a PDF document. - The
PdfDocumentProcessorremoves existing signatures from a document when the file is saved. However, if you usePdfDocumentProcessorto apply a signature, it is retained.
Use the solution from this example for more flexible approach: How to Apply Multiple Signatures
