GetUserPermissions
Security and signatures
Description
Returns the raw /P permission word of the loaded document, verbatim as stored in the encryption dictionary. A set bit means the operation is permitted and a cleared bit means it is denied; the common bits follow ISO 32000-1 Table 22
Syntax
Delphi
Function TPDFlib.GetUserPermissions: Integer;Return values
| >= 0 | The raw /P permission word; test individual bits to decode the granted rights |
|---|---|
| 0 | No document is loaded |
Remarks
Common permission bits: 4 = print, 8 = modify contents, 16 = copy text and graphics, 32 = annotate, 256 = fill form fields, 512 = copy for accessibility, 1024 = assemble the document, 2048 = print high resolution. Permission restrictions only take effect in an encrypted document opened with the user password; use IsOwnerPassword to check whether the owner credential with full rights was used, and EncodePermissions to pack permission booleans when configuring encryption. The function takes no parameters
