Abstract
Various embodiments described herein provide systems, methods, software, and data structures that allow a page description language reader application, such as Adobe® Acrobat®, to provide a view of the assets compressed within a compressed archive. These and other embodiments including applications that may interleave one or more compressed archives within a page description language file, such as a PDF file. This interleaving leverages properties of both compressed archive files and page description language files to insert object markers around compressed assets within the compressed archives and references to at least some of the object markers in an index portion of the page description language files. As a result, compressed assets of compressed archives included in a page description language file package may be viewed within the listing of assets of the page description language file. These and other embodiments are described in greater detail below.
