    Solved: pyUNO Converter

    Hi!

    This script will convert files to PDF with OpenOffice.
    Other formats (html, doc ...) should be possible, too.

    Have a nice day,
    thomas


    # OpenOffice1.1 comes with its own python interpreter.
    # This Script needs to be run with the python from OpenOffice.org:
    # /opt/OpenOffice.org/program/python
    # Start the Office before connecting:
    # soffice "-accept=socket,h ost=localhost,p ort=2002;urp;"
    #


    # pyUNO Imports

    import uno
    from com.sun.star.be ans import PropertyValue

    # Python Imports

    import os
    import sys



    # For a list of possible export formats see
    # http://www.openoffice.org/files/docu...scription.html
    # or
    # /opt/OpenOffice.org/share/registry/data/org/openoffice/Office/TypeDetection.x cu

      Nice.

      Is there any way to start soffice without a display?
      Could be used to offer a webservice-documentconvert er.

          No, but there is a special X-Server which does not need
          a real display. But I don't think that it is thread save.

          Untested:
          You could start e.g. 5 office instances listening on 5
          different ports and syncronize the access yourself.

          Fortunately I only need it for batch processing.

              Nice work!

              One question though, doesn't this work only for OOo writer files (not
              Draw or Calc files)?

              I tried hacking it, and in the end, simply tried all output filters
              that put out PDF in succession, until one worked.

              I _know_ this is a hack, but I couldn't find any information on how to
              use pyUNO to query OO and return what _type_ of file it had
              opened.....

              How _does_ one do that, anyway?

              Thanks,
              Duane

                  One could create the properties list in one go:

                  properties = [PropertyValue() for i in range(3)]

                  And then fill it in:

                  properties[0].Name = ...
                  properties[0].Value = ...
