  60
  61     Useful e.g. for hybrid PDF
  62
  63     @param rPDFFile
  64     URI of the pdf file
  65
  66     @param o_rOutMimetype
  67     Output parameter. Receives the mime type of the
  68     substream. Used to distinguish between
  69     draw/impress/writer/calc during import
  70
  71     @param o_rOutPwd
  72     In/Out parameter. If given password is wrong, user is queried
  73     for another (if bMayUseUI is true)
  74
  75     @param xContext
  76     Component context
  77
  78     @param rFilterData
  79     Basically used to pass on XFilter::filter properties (function
  80     uses it to retrieve interaction handler)
  81
  82     @param bMayUseUI
  83     When false, no dialog is opened to query user for alternate
  84     password
