  71     Useful e.g. for hybrid PDF
  72
  73     @param rPDFFile
  74     URI of the pdf file
  75
  76     @param o_rOutMimetype
  77     Output parameter. Receives the mime type of the
  78     substream. Used to distinguish between
  79     draw/impress/writer/calc during import
  80
  81     @param o_rOutPwd
  82     In/Out parameter. If given password is wrong, user is queried
  83     for another (if bMayUseUI is true)
  84
  85     @param xContext
  86     Component context
  87
  88     @param rFilterData
  89     Basically used to pass on XFilter::filter properties (function
  90     uses it to retrieve interaction handler)
  91
  92     @param bMayUseUI
  93     When false, no dialog is opened to query user for alternate
  94     password
