           Summary: Support extractions of embedded objects
           Product: Ghostscript
           Version: other
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P4
         Component: General
        AssignedTo: support at artifex.com
        ReportedBy: goldart.geo at yahoo.com

Ever since Adobe Acrobat 7 natively supports 3D objects, there is a growing
problem that documents created these revisions of Acrobat cannot be used by
Ghostscript. Not just part of the file, but potentially all of it.

So why not just download Adobe Reader? First of all, not all operating systems
supported by Ghostscript can run Adobe Reader. In particular, releases of Adobe
Reader for Unix-based systems (including Linux) tend to be 1 major revision
behind. Furthermore, the system requirements for Adobe Reader has been growing
in exponential scale, so even Windows machines will have trouble of getting the
Reader running, even when the embedded contents themselves do not need such
powerful hardware to run.

Since it is unlikely that Ghostscript will support viewing and executing
embedded document objects the way Adobe Reader does any time soon, a practical
alternative is to replace references to these objects into links when viewed by
Ghostscript viewers such as GSview, which can be chosen by users to save the
embedded objects into files, which can be viewed by external applications. This
can help document owners to convert PDF with embedded objects into a more
editable format such as (X)HTML, in which free tools are widely available.
