``'pxunit'``
the value of the ``px`` when used in image attributes ``width`` and
``height``. The default value is ``'0.75bp'`` which achieves
``96px=1in`` (``1in = 72bp = 72.27pt`` in TeX, and ``1pt=65536sp``,
all dimensions
in TeX are internally integer multiples of ``sp``). To obtain for
example ``100px=1in``, one can use ``'0.01in'`` but it is more precise
to use ``'47363sp'``. To obtain ``72px=1in``, use ``'1bp'``.
``96px=1in`` (``1in = 72bp = 72.27pt``.) To obtain for
example ``100px=1in`` use ``'0.01in'``; for ``72px=1in``,
simply use ``'1bp'``; for ``90px=1in``, use ``0.8bp`` or ``0.803pt``.
