As of version 7.0 the Muhimbi PDF Converter Server Platform supports the ability to set PDF Viewer Preferences.
Viewer Preferences are hints for the application that is used to view the PDF file, e.g. Adobe Acrobat. These hints are embedded in the PDF file and control such things as the visibility of the Menu and Toolbars, the various panels such as Bookmarks / Attachments, or even viewing the PDF in full screen mode. Please be aware that these are merely hints and not every PDF Reader supports all of them.
