AVDisplay (Display Properties)
This preference category contains the following subfeature(s):
Reference Objects View Mode (XObjects)
Reference XObjects are defined in the PDF Reference fifth edition. A reference XObject is a form XObject which contains an optional Ref sub-dictionary. The sub-dictionary specifies a page in some target PDF file. The form XObject provides a proxy for the page in the target file, and Acrobat can display or print the proxy as well as the referenced page from the target file in place of the proxy.
On Windows, this feature interacts with the Trust Manager (TM). In fact, settings configured through the user interface work in tandem with TM settings and will not take effect unless privileged locations are defined for the parent document referencing the XObject. This is true whether enhanced security is enabled or not. To configure a privileged location manually (not through the UI), verify that cCrossDomain and cExternalStreams are set for the parent document.
