Is there a way to map the Aspose.Pdf.Document.Permissions
to a Aspose.Pdf.Facades.DocumentPrivilege
?
I want to only modify specific PDF security properties on a document, e.g. ONLY disallow copy and leave the rest of the attributes untouched.
But to do so, I have to find the existing properties and modify them, before calling :
using (var pdfOutput = new PdfFileSecurity(doc))
{
pdfOutput.EncryptFile(Password, OwnerPassword, modifiedPrivileges, KeySize.x256, Algorithm.AES);
}
I have started like that:
var permissions = (Aspose.Pdf.Permissions)doc.Permissions;
var docP = DocumentPrivilege.AllowAll;
docP.AllowAssembly = permissions.HasFlag(Aspose.Pdf.Permissions.AssembleDocument);
docP.AllowCopy = permissions.HasFlag(Aspose.Pdf.Permissions.???);
But there is no matching property for AllowCopy
and some other properties.
Also, I will need to fill the ChangeAllowLevel
, CopyAllowLevel
, etc on the DocumentPrivilege
object and I have no idea how.
Any ideas?
