Subject DO NOT REPLY [Bug 49479] New: Option to make PDF binary equal between runs (for Apache Forrest)
Date Mon, 21 Jun 2010 12:39:00 GMT

           Summary: Option to make PDF binary equal between runs (for
                    Apache Forrest)
           Product: Fop
           Version: 1.0dev
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: pdf
        AssignedTo: fop-dev@xmlgraphics.apache.org
        ReportedBy: jeremias@apache.org

FOP currently always creates a file ID in the PDF trailer even though it's
optional. It is required mostly be PDF/A and PDF/X. It may make sense to
disable the generation via a configuration item. We probably shouldn't disable
it by default because some people may rely on it by now.

Second, the metadata date is always set to the current date even if it is given
in an XMP packet. That also prohibits binary equality.

Adding this would allow Forrest to produce the same PDFs from run to run so
they don't cause SVN diffs all the time.
