  67     URI of the pdf file
  68
  69     @param o_rOutMimetype
  70     Output parameter. Receives the mime type of the

  72     draw/impress/writer/calc during import
  73
  74     @param o_rOutPwd
  75     In/Out parameter. If given password is wrong, user is queried

  79     Component context

  85     @param bMayUseUI
  86     When false, no dialog is opened to query user for alternate
