Document Permissions
A set of flags specifying which operations shall be permitted when the document is opened with user access.
Entries
Modify the contents of the document by operations other than those controlled by bits 6, 9, and 11.
(Security handlers of revision 2) Copy or otherwise extract text and graphics from the document, including extracting text and graphics (in support of accessibility to users with disabilities or for other purposes). (Security handlers of revision 3 or greater) Copy or otherwise extract text and graphics from the document by operations other than that controlled by bit 10.
Add or modify text annotations, fill in interactive form fields, and, if bit 4 is also set, create or modify interactive form fields (including signature fields).
(Security handlers of revision 3 or greater) Fill in existing interactive form fields (including signature fields), even if bit 6 is clear.
(Security handlers of revision 3 or greater) Extract text and graphics (in support of accessibility to users with disabilities or for other purposes).
(Security handlers of revision 3 or greater) Print the document to a representation from which a faithful digital copy of the PDF content could be generated. When this bit is clear (and bit 3 is set), printing is limited to a low-level representation of the appearance, possibly of degraded quality.
Functions
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants.
