Class FSDK.SecurityHandler is the base class that represents a security hander used for encrypting PDF document. It has following derived classes:
To set a security handler to a PDF document, please call function FSDK.PDFDoc.SetSecurityHandler, then the security handler will take effect in later saving process. To get the security handler used for a PDF document, please call function FSDK.PDFDoc.SetSecurityHandler.
| FSDK.SecurityHandler.GetSecurityType | ( | ) |
Get the encryption type of current security handler.
| FSDK.SecurityHandler.IsEmpty | ( | ) |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
