[Vxl-maintainers] left or right shifting pixels.

[Ian S. <ian...@st...>]

Marc,

I've been talking to some other users of non 8*n bit images here, and the
consensus is that vil file loaders should default to keeping data in the
least significant bits of the C++ pixel type.

So get_view() on an NITF image would return pixels valued at 0 to 2047. If
you think NITF and other non 8*n bit images should have their bits shifted
right, let me know and I'll open the debate to the reflector.

I've added a vil_property_quantisation_depth which you may find useful.

Ian.
