You can use the Reader Extensions service to apply usage
rights to PDF documents. Usage rights pertain to functionality that
is available in Acrobat Pro but not in Adobe Reader. Such functionality
includes the ability to add comments to a document, fill forms,
and save the document. PDF documents that have usage rights added
are called rights-enabled documents. A user who opens a rights-enabled
PDF document in Adobe Reader can perform the operations that are
enabled for that document.
Here is a list of the usage rights and the actions that users
can perform in Adobe Reader when each usage right is enabled:
- Basic form fill-in:
- Users can fill in form fields and save files locally.
Note: A message prompting users to fill the form is
displayed to users of Adobe Reader 7. This message is not displayed
in Adobe Reader 8.
- Import and export form data:
- Users can import and export form data as FDF, XFDF, XML,
and XDP files. If you select this feature, Basic Form Fill-In is
also automatically selected. When you select this usage right, also
enable the Database and Web Service Connectivity usage right or
the Embedded File Attachments usage right (depending on the usage
rights required).
- Submit outside web browser:
- Users can submit form data by email or offline. If you select
this feature, Basic Form Fill-In is also automatically selected.
- Database and web service connectivity:
- Users can access the database or call the web service that
is defined within the form. If you select this feature, Basic Form
Fill-In is also automatically selected.
- Add, delete, and change form fields:
- Users can add, delete, or modify fields on the form. If you
select this feature, Basic Form Fill-In is also automatically selected.
- Create pages from templates:
- Users can spawn pages from the form template for forms that
are created in Acrobat. Users create pages from template pages within
the same form. (Available in XFA documents but when selected, the
usage right is not applied to the final saved document.) If you
select this feature, Basic Form Fill-In is also automatically selected.
- 2D barcode decoding:
- Users can use 2D barcodes with third-party scan decode solutions.
If you select this feature, Basic Form Fill-In is also automatically selected.
- Digital signatures:
- Users can digitally sign and save the PDF document. If this option
is not selected, users can still validate, view, and print the document
that has a digital signature.
- Commenting:
- Users can create, edit, delete, import, and export comments. Comments
are stored with and transmitted with the entire file. If this option
is not selected, users can only review comments in the PDF document.
- Embedded file attachments:
- Users can add, remove, modify, or export file attachments
and files in a PDF package (formerly known as a PDF portfolio).
