It is possible to get idempotent behavior by using the
:qpdf:ref:`--static-id` or :qpdf:ref:`--deterministic-id` option with
qpdf and running it *three* times so that you are processing the
output of qpdf on its own previous output. For example, in this
sequence of commands:
:qpdf:ref:`--deterministic-id` (or, for testing only,
:qpdf:ref:`--static-id`) option with qpdf and running it *three* times
so that you are processing the output of qpdf on its own previous
output. For example, in this sequence of commands:
::
qpdf any-file.pdf 1.pdf
qpdf --static-id 1.pdf 2.pdf
qpdf --static-id 2.pdf 3.pdf
qpdf --deterministic-id 1.pdf 2.pdf
qpdf --deterministic-id 2.pdf 3.pdf
the files :file:`2.pdf` and :file:`3.pdf` should be *byte-for-byte*
identical. The qpdf test suite relies on this behavior. See also
:qpdf:ref:`--static-aes-iv`.
:qpdf:ref:`--static-aes-iv`, which should also be used only for
testing.
