This example illustrates how to use the PdfDocumentProcessor class to sign a PDF document.
Important
The Universal Subscription or an additional Office File API Subscription is required to use this example in production code. Please refer to the following page for pricing information: DevExpress Subscription
The approach in this project has the following limitations:
- The
PdfDocumentProcessor
class allows you to apply only one digital signature to a PDF document. - The
PdfDocumentProcessor
removes existing signatures from a document when the file is saved. However, if you usePdfDocumentProcessor
to apply a signature, it is retained.
Use the solution from this example for more flexible approach: How to Apply Multiple Signatures
