When I add the pdf on the page manager "pm.Add(sourcefile.Document)", the following error is showed.
2) System.NotImplementedException - Encrypted files are currently not
I am sure that the file is existed. also, the file can be opened by adobe reader.
So, how do I enhance the program to read the pdf files?
As prompted by the exception, encrypted files are currently not supported.
In order to read encrypted files you have to implement § 3.5 of PDF Reference 1.7.
