Optional. Enable any of these values by adding it to the profile and setting it equal to ON.
|discard-alternate-images||Removes alternate versions of the same image found in the PDF document. A PDF document can be set up to specify alternate images, or multiple versions of one image within the same document. These images can be used to meet different needs. For example, a PDF could present one image with a lower resolution for display on a monitor, and an alternate image with a higher resolution to use when the PDF document is sent to a printer. These images can make a PDF document very large. Today alternate images are rarely used.|
|discard-thumbnails||Removes document thumbnails. Thumbnail images are used to preview pages in a PDF document and appear in a panel on the left side of the viewer window. A user could scroll through a series of thumbnails to find a page he or she is looking for.|
|discard-document-tags||Removes document tags. Tags are sometimes added to PDF documents to enable external applications, like Adobe Illustrator, to view and manipulate those documents if needed.|
|discard-bookmarks||Removes document bookmarks. Bookmarks make navigation easier. They appear on the left side of the viewer window, in the form of a Table of Contents, and are commonly attached to headings within the document. A user can click on any value in the Table of Contents and move directly to the part of the page where the bookmark is found. And bookmarks can be used apart from a table of contents to mark a place in a PDF document to navigate to. Defaults to off, bookmarks not removed. Note that bookmarks no longer appear in most PDF documents, because they can be generated automatically as needed by modern viewing tools.|
