Reader Extensions

Reader Extensions allows you to manipulate usage rights on PDF documents. Usage rights pertain to functionality that is available in Acrobat but not in Adobe Reader. Functionality controlled by Reader Extensions 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.

In addition to PDF documents, you can use Reader Extensions operations to manipulate usage rights for PDF forms.

Wichtig: When you use Reader Extensions to add usage rights to a static PDF form for use with Workspace, save the form by clicking Take Offline. This step preserves the usage rights. Clicking the Save button in Adobe Reader causes the usage rights to be unavailable to the user.

For information about using the Reader Extensions service, see Services Reference for Adobe LiveCycle ES4.

    Apply Usage Rights operation

    Applies usage rights to a PDF document. Before you use the Apply Usage Rights operation, import and configure a Reader Extensions Credential. (See Configuring credentials for use with Reader Extensions inLiveCycle Administration Help.)

    If you are applying usage rights to a PDF form for use in Workspace, inject the Form Bridge library as well. Perform the steps in the following order:

    1. Create the PDF using, for example, renderPDFForm operation (Forms service).

    2. Use Inject Form Bridge operation (Form Augmenter service) to add the Form Bridge library.

    3. Apply usage rights.

      If you inject the Form Bridge libraries after applying usage rights, the usage rights are invalidated. Any combination of encrypting, certifying, and applying usage rights to the same document must occur in the following order. These services must be invoked within a short-lived process:

    4. Encrypt (Encryption service or Protect Document operation operation of the Rights Management service)

    5. Certify (Signature service)

    6. Apply usage rights
